Hulls, Hydrofoils, and Float Tests in the NACA Tanks, 1915 to 1945

By Jay Shaw

Since the establishment of the National Advisory Committee for Aeronautics (NACA) in 1915, it had worked closely with the United States Navy. Not only had the US Navy partnered with NACA, but the creation of the latter was also a rider to the former’s funding bill.[1] This history of NACA has been overshadowed by its successor, the National Aeronautics and Space Administration (NASA), into which the former was absorbed in 1958. Thus, much of the critical work by NACA has been overlooked. Indeed, if NACA is remembered at all, it is for using wind tunnels in aeronautical research, but there was much more that it was responsible for. This article redresses this deficit by examining how NACA used water tanks in seaplanes’ aeronautical and hydronautical advancements after the First World War. It also highlights the people and agencies involved in the research and the means of conducting the research.

The United States Navy, Seaplanes, and the First World War

The US Navy, realising that aircraft would play a vital role in any future war, recognised that something had to be done to improve its readiness and improve its fleet of seaplanes The US Navy partnered with NACA to investigate and perform research on its aircraft, including seaplanes and flying boats. These planes would be critical in defence and coastal patrols. As a part of the first line of defence against German U-boats, the seaplanes would be a priority for the US Navy. The seaplane was considered a fixed-wing aircraft with a fuselage designed for floatation and containing a hull.[2] However, because it realised that aviation was still a technology in its infancy, the US Navy requested that NACA help make the naval seaplanes as efficient as possible. NACA, in supporting the tasking of the US Navy through its work on seaplanes, ensured a long and productive close bond with the Navy.

By the end of the First World War, the US Navy had several seaplanes with varying hulls, float types, and missions. These seaplanes operated from bases on shores because the US Navy did not have aircraft carriers or capital ships to launch such craft. The prevailing view then was that if the enemy were to attack, it would be by submarine, so it made sense to send patrols out from the shore to search for submarines. Several kinds of seaplanes were designed and used by the US Navy during the First World War. In 1919, Commander H.C. Richardson, the Superintending Constructor of Naval Aircraft for the US Naval Buffalo district in Buffalo, New York, who had also been Secretary to NACA’s main committee on formation in 1915, explained that:

[t]he principal work was done with two types of seaplanes, namely, the HS-2, the single-motored plane developed from the HS-1, and the H-16, a copy of an English seaplane.[3]

These two seaplanes were used because they were the most readily available. This shows how poorly the US Navy seaplane fleet was in 1919. However, according to Richardson:

The Navy Department fully appreciate[d] the desirability of experimenting to improve existing types and the development of new types of seaplanes and airplanes, directed to the solution of those problems which have arisen in the war and, more particularly, to the development of seaplanes or airplanes for operation with the fleet.[4]

Richardson was an active proponent of seaplanes for the US Navy. Therefore, because of the efforts of those such as Richardson, the US Navy was on track to update its seaplane fleet.

Unfortunately, the seaplanes of this period were unscientifically constructed. Their range was not that far, and their stability in flight left much to be desired. Actual aerodynamic testing was needed to ensure that any aircraft was worthy of combat and that the seaplanes were no exception. Richardson wrote in 1919 that:

[t]he problem confronting the Navy was largely determined at the time the United States entered the war [1917] by the fact that the operations of the German and Austrian fleets had been reduced principally to minor raids […] and the only real sea-going operations comprised the activity of submarines.[5]

This would be the primary mission of the seaplanes for many years: the patrol of waters in search of submarines. The submarines’ effect in the First and Second World Wars should not be taken lightly. The amount of cargo tonnage that could be destroyed by an undetected submarine could be immense.

Richardson’s 1919 article is crucial as he addressed the US Navy’s needs and how the seaplanes could aid it. His outline reads almost like a ‘wish list’ that NACA would eventually find itself working on. First, Richardson felt that performance, first and foremost, relied upon horsepower. He argued that:

[t]he performance in power flight is determined by the horsepower required and the horsepower available, and of course, the latter must always exceed the former or power flight is not attainable.[6]

Considering that Richardson wrote this in 1919, he seems to have firmly grasped the needs of seaplanes. However, the power plants of any aircraft currently were still in an age of infancy. As such, Richardson’s idea that seaplanes were reliant on horsepower was unfortunately ahead of the technology that would make the machines efficient.

Richardson also understood that lift was an essential component of flight. He explained that:

[t]he lift of an airplane surface and its resistance to advance are determined by the lift and drift factors, which vary with the type of section used and also with the angle of attack at which the surface is presented to the relative stream of air.[7]

The US Navy realised, however, as much as Richardson showed advanced thought on the subject, that the research involved was outside the Service’s scope. NACA, set up as an agency that was available to help government and civil agencies in aeronautics research, would be the agency to help the US Navy address the fundamental science of seaplane aeronautical research.

The Importance of NACA’s Research

While often overshadowed by NASA, the work of NACA deserves examination because of the enormity of its contribution to aeronautics. As NASA historian James Schultz explained:

[t]hroughout its history, with research and applied engineering, the Center [Langley] has been responsible for some of the 20th century’s fundamental aeronautical and aerospace breakthroughs. The Nation’s first streamlined aircraft engine cowling was developed at Langley Laboratory […] the tricycle landing gear; techniques involving low drag-producing flush riveting; [and the] development of the sweptback wing.[8]

Similarly, historian Michael Gorn asserted:

[t]he proliferation of wind tunnels [about thirty had been built at Langley up to the 1950s] reflected the NACA’s true institutional identity: it concentrated on aeronautics.[9]

While Gorn is correct, NACA could not have focused solely on aerodynamics and prospered. Aerodynamics was just one piece of what NACA did. It was established to investigate all flight modes, and hydrodynamics was a crucial part of NACA’s work. While not as aerodynamically sophisticated as land planes, seaplanes and flying boats needed hydrodynamical studies to meet the needs of the US Navy. It is a mistake to overlook this field that so many within NACA worked on.

Once NACA started its research on hydrodynamics, it did so without any presumptions and began its research by looking at the fundamentals of the aircraft. George W. Gray, in his early history of NACA, explained this adeptly. He stated that:

[a] large part of the effort of the hydrodynamic staff at Langley has been expended upon the twin problems: trying to effect a seaplane body that will combine low water resistance with low air drag.[10]

Even before this, however, the question was whether seaplanes could even take flight. Then, again, the problem was that of power plants. As Gray pointed out, the studies:

[h]ad yielded some disappointing surprises: new designs that would not take off at the speeds planned or that would not lift the desired loads at any attainable take-off speed.[11]

With the water tanks of NACA, however, the guesswork was taken out of the equation. However, none of this would have been possible, at least in a reasonable amount of time, without some organisation to make it happen.

Langley and the Water Tanks

Langley, located at Hampton Virginia, was NACA’s research centre, established in 1917. It focused primarily on aeronautical research but would eventually be used to test space equipment such as the Apollo lunar module. However, the first ten years at Langley comprised only the testing of aeroplanes. There was no work at all done on seaplanes. To do this work, NACA had to have something other than a wind tunnel to test the seaplanes.[12]

The drag tank also called a tow tank, drag tunnel, or even the drag basin, was the solution to the research needed. Gray stated that:

[m]any of the studies in wind tunnels were applicable to seaplanes, and they in common with landplanes benefited from improvements in wings, propellers, engine cowlings, and other developments of the 1920s.[13]

The study variables were applicable, but these were still seaplanes, and there was a need to test them in water. Gray elaborated that NACA knew that it needed a better way to test the seaplanes:

[i]t was recognised that the airplane on the water has problems that are not shared by the airplane in the air or on the landing strip, and in 1929 the Committee in Washington decided to enlarge the organisation and equipment at Langley to provide for research in hydrodynamics.[14]

It was then that hydrodynamic research began at Langley.

Langley constructed two tanks: tank number one and tank number two. Tank number one became operational on 27 May 1931 for $649,000.[15] Its purpose was ‘to study the hydrodynamic resistance and other performance features of water-based aircraft.’[16] A vital design team member was Starr Truscott, who published numerous studies based on research from tank one. A few additions were made to the tank, including a new higher-speed (80-MPH) carriage (a rail that the aircraft being tested sits on) installed in 1936-1937 and a tank extension of 900 feet to 2,960 feet in 1936.[17] Eventually, the need for another tank would arise, leading to the construction of tank two.

Tank number two, operational on 18 December 1942, again had Truscott, along with John B. Parkinson and John R. Dawson, on the design team.[18] The basin was 1,800 feet long by 18 feet wide and 6 feet deep. It also had a 60-MPH carriage.[19] The express purpose of tank number two was ‘to test models of floats for seaplanes and hulls for flying boats by dragging them through seawater.’[20] According to Gray, the significance of tank two was that:

[r]esearchers experimented with radical departures from accepted hull design, trying to find the specifications for a seaplane body that would combine freedom from porpoising and skipping, low water resistance, and superior performance in the air. Out of these experiments came a novel design known as the hull with a planing tail.[21]

Every step in the building of the tanks, from the basin to the tires on the towing carriage, had to be carefully thought out to ensure the best product for research use. Truscott, one of the designers of both tanks, realised that using NACA tanks required certain necessary features solely for use with the seaplanes.[22]

Truscott related that the tank located at Langley was:

[o]f the Froude type; that is, the model which is being tested is towed through still water at successive constant speeds from a carriage spanning the tank. At each constant speed, the towing pull is measured, the trim and the rise, or change of draft, are recorded and, if the model is being towed at a fixed trim, the moment required to hold it there is measured and recorded.[23]

The tank itself was covered by an enclosure meant to protect it from the water itself (so that turbulent water after a test could settle more quickly), wind, and the weather, rather than to provide any comfort to the engineers.[24]

Pneumatic tires were installed and were ‘each driven by an independent electric motor through a single-reduction herringbone pinion and gear. The […] tires are high-speed bus or truck tires, with smooth treads.’[25] The carriage had to have the means to propel itself, which was achieved using ‘our electric motors propelling the car […] nominally of 75 horsepower, but for short periods they may be safely called upon to deliver 220 horsepower each.’[26] ‘Finally, the device used electrical braking to break the current for regenerative braking.’[27]

Given the construction of the tanks, much work had to come together to test seaplanes. Of course, the whole purpose was to test the seaplanes for fundamental problems that could inhibit the aircraft’s performance. Resistance, porpoising, skipping, and performance were why the tanks existed. Solutions to these problems were needed for a more efficient aircraft. NACA engineers sought to reduce resistance; the force encountered when a plane is in the air moving forward or a seaplane in water, to help with take-off and landing.

Porpoising, a dangerous event that often occurs in the water, is something that NACA was tasked to find a solution to. According to Kenneth Davidson and F. W. S. Locke, Jr., writing for the Stevens Institute of Technology in 1943:

[p]orpoising is a self-sustaining oscillatory motion in the vertical longitudinal plane [… ] and can originate in an instability of the uniform longitudinal motion in smooth water […] in the words of one test pilot, it is always unpleasant and it may be catastrophic.[28]

Essentially a seaplane will move up and down in the water out of control of the pilot. So it is easy to understand why the US Navy was interested in the dynamics of porpoising and what needed to be done to eliminate it. If left unchecked, not only could the seaplane not fly, but it could also be damaged, or worse yet, the pilot injured or killed.

Performance was made up of several things. Engine performance, aerodynamics, and propellers were factors in all aircraft, but with the seaplane, there was a demanding service life on the water. In addition, s were composed of thousands of rivets, so corrosion was a considerable fear. It could be disastrous if the corrosion worked through a rivet at the wrong time. The hull of the seaplane was another vital factor. The construction, what it was made of, the aerodynamics, and how to prevent porpoising and skipping of the aircraft were things that NACA still needed to work out.

With the tow tanks available, miniature models could be constructed of the hulls or floats of the seaplanes, put upon the carriage, and pulled at the desired speed. If the results did not achieve the desired results, costly mistakes could be prevented. This opened new doors for aeronautical research that paid huge dividends in the coming years. While NACA was still beginning its seaplane research, progress would come more rapidly with the tow tanks at hand.

Fundamental Research

In 1935, NACA found itself in a position to make future research easier. Engineer Antonio Eula performed tank tests on seventeen different hulls and floats.[29] Eula purposely picked a random number of floats that had been tested in the laboratory over the last few years. He did this because:

[i]t affords an opportunity to draw some general conclusions regarding seaplane floats of given weight, given wing structure, any given position of the center of gravity.[30]

Another reason is that not much data existed to make work easier for future engineers. His most important conclusion drawn from the tests was that ‘the best models have a maximum relative resistance not exceeding 20 percent of the total weight.’[31] Just that information itself was enough to help any future engineers working with the drag tanks to give them a starting point from which to work.

Along with porpoising, skipping continued to be a problem with seaplanes. During the Second World War, the problem of skipping was considered a significant enough problem that needed further research. In 1943, John B. Parkinson at NACA addressed the problem. He began by defining just what skipping was. He reported that ‘skipping is a form of instability encountered in water take-offs and landings, so-called because of the resemblance of the motions of the seaplane to those of a skipping stone.’[32] Rising out of the water before the seaplane achieved flight was hazardous. A plane entirely out of the pilot’s control can lead to injuries, if not death.

One of the critical problems with the testing up to this point was that scientific testing had not occurred. Parkinson explains that ‘investigations of skipping have been mainly qualitative and the data have been based on the impressions of pilots or observers.’[33] Using models and even full-size aircraft for testing, Parkinson established that instability caused most problems. Using measurements taken from the fore and aft of the step-in hull helped determine where the problem for each type of seaplane was located. Once that was established, the engineers could make the corrections. Of course, it could never eliminate all problems because any seaplane on the water is prone to unpredictable water. However, it did go far in helping establish methods to solve the skipping problems.

It was realised that the research had to be compiled to make it easier for future engineers to find the information they were looking for. So, in September 1945, engineers James M. Benson and Jerold M. Bidwell released a bibliography containing information about seaplanes.[34] In this bibliography, many details covering everything from conventional hulls and floats to floating and handling were written about in a way that compiled the common information in past reports. Not only would this make it easier for future researchers, but the bibliography also pointed out areas in which more work needed to be done. Examples such as this are one of the reasons that NACA was able to achieve the success that it had.

NACA Water Tank Research and its Impact on Second World War Seaplanes

The Consolidated PB2Y Coronado is an example of how this research aided in Seaplane use during the war. In its original design, when fuelled for a long-range mission, this seaplane had a gross weight of 46,000 pounds of which 3,000 pounds was the payload. The US Navy wished to increase the payload.[35] Using models of the Coronado in Tank No. 1, the NACA changed the line of the step of the hull and installed ducts for ventilating the bottom area aft of the step. This increased the gross weight to 68,000 pounds, of which 12,000 pounds was payload. It’s stability was so assured that the plane, during its war service in the Pacific Islands was repeatedly used to make landings on dark nights when the seeing is poor, and the craft must descend on a steady glide path until water is touched, a more hazardous procedure than daylight landing.[36]

Conclusion

The success of NACA was based on hard work and dedication to research. Working alongside government agencies such as the US Navy and even civilian aircraft manufacturers, NACA helped the United States evolve from a country far behind Europe in aeronautical research to the world’s leader in aeronautical research. The research conducted on seaplanes, long overlooked, helped refine the seaplanes, and even today, seaplanes are still in use.

#ResearchNote – It is time for another Biography of Ira Eaker

By Luke Truxal

For those who study the history of the United States Air Force and its forebears, there is a noticeable gap in the historiography regarding biographies of Second World War air force commanders. There are several biographies for men such as General Carl Spaatz, General of the Air Force Henry H. Arnold, General James Doolittle, General Curtis LeMay, and even Major General Haywood Hansell. Yet, many other prominent commanders, staff officers, and theorists do not have their own biographies. However, this research note solely focuses on General Ira Eaker, who, in 1943, commanded what became the US Eighth Air Force, the Mediterranean Allied Air Forces in 1944 and was deputy Chief of the Air Staff for the United States Army Air Forces in 1945.

James Parton has largely written Eaker’s history in “Air Force Spoken Here”: General Ira Eaker and the Command of the Air. Parton’s biography is a strong defence of Eaker. In many cases, he has created much of the narrative that we accept regarding Eaker’s performance as a commander during the Second World War. However, there is one problem with Parton’s book; he was Eaker’s staff officer. Given this, Parton’s book jumps between biography and personal memoir in several places. For example, when writing about Eaker’s defence of daylight precision bombing at the Casablanca Conference in 1943, Parton slips into a personal memoir. In a paragraph, he describes the trip to Spaatz’s headquarters, the poker game he played with Eaker and Spaatz, and how he edited Eaker’s proposals for the Casablanca Conference.[1] It is unclear whether this can be classified as a biography since it is unclear if Parton is writing about himself or Eaker. Also, as a staff officer deeply devoted to Eaker, Parton may not be the general’s best or most objective biographer. Simply put, Eaker needs a new biography.

For those interested in writing a biography on Eaker, there are several places to start. First, Parton’s biography is a great place to get background information on Eaker, even if the analysis is sometimes questionable. Another series of sources that need to be examined are the books that Eaker published with Arnold before the Second World War. Arnold and Eaker wrote: Army Flyer, Winged Warfare, and This Flying Game.[2] These books lay out their vision for the future of air power and, in some cases, offer analysis of air campaigns during the Second World War before the entrance of the United States into the conflict. These books give some insight into Eaker as an air power theorist and precision bombing advocate before the war. Three major archives should be consulted for wartime records. First, the Library Congress has Ira Eaker’s papers. Speaking from personal experience, they are well-organised and easy to work through. Even better, several vital figures whom Eaker corresponded with also deposited their papers at the Library of Congress. Another archive to consult is the Air Force Historical Research Agency, where you can find records on the Eighth Air Force and Mediterranean Allied Air Forces. Finally, the National Archives and Records Administration has more records and correspondence.

Research is not the problem with writing a biography on Eaker. He wrote a lot about air power before, during, and after the Second World War. There is much research readily available on Eaker. This is purely speculation, but the reason why there is not a biography on Eaker is most likely that it is a hard biography to write. Eaker is not a polarising figure. Biographers note that they either fall in love with or hate the person they are writing about. It is hard to do that with Eaker. He is a likeable person and, at times performs quite well as a commanding officer. Yet, he also makes several significant mistakes during the war as well. It is hard to write a book analysing an officer whom both deserves blame for the failures of the 1943 air offensives against Germany and, in the same breath, say he played a major role in the success of the air war in 1944 and 1945.

In conclusion, it is time to put the James Parton book on Eaker aside and write a new biography on Eaker to start a proper historical debate on his career. There is ample archival material available to sift through and analyse. The challenge will be how to assess his performance during the war. Here is a thought to possibly hang onto for those who might want to take up this project. Maybe the challenge of writing a biography about Eaker is that he is representative of the struggles that early American air commanders faced during the strategic bombing of Germany in 1942 and 1943. Eaker was testing new ideas in a new form of warfare and without ample resources as the commander of the Eighth Air Force. He made several errors in 1943 that was amplified by his lack of resources. Yet, with more resources and experience, his performance improved over time. In many ways, Eaker represents the struggles that many American officers faced during the air war against Germany.

#BookReview – Rearming the RAF for the Second World War: Poor Strategy and Miscalculation

Adrian Phillips, Rearming the RAF for the Second World War: Poor Strategy and Miscalculation. Barnsley: Pen & Sword, 2022. Notes. Bibliography. Index. Hbk. xxvi + 350 pp.

Reviewed by Dr Matthew Powell

The history of the rearmament of the Royal Air Force (RAF), and the British aircraft industry in the inter-war period, more generally, has undergone a degree of revision over recent decades, mainly through the works of Sebastian Ritchie and David Edgerton. In this work, Adrian Phillips looks to challenge this new orthodoxy. Phillips seeks to show that the RAF adopted an incorrect way of conceptualising air warfare in the mid-to late-1930s. Phillips claims that the Air Ministry and the wider RAF incorrectly prioritised bombers over fighters when rearmament began in the 1930s. Phillips further contends that this prioritisation can be traced back to the theorising of Marshal of the Royal Air Force Lord Trenchard, the RAF’s Chief of the Air Staff in the 1920s. Despite dispelling several myths about RAF expansion in the inter-war period, Phillips does not provide an overly convincing case for several reasons.

The critical issue with Phillips’ book is that it suffers from a general lack of understanding of the wider historical context of the RAF’s development in this period. Despite a relatively extensive bibliography, it appears that many more recent works in this area have not been consulted. This illustrates a broader bias inherent in Phillips’ work, namely that the RAF was wrong in its thinking.

Several examples sufficiently highlight the problem of understanding present in this work. For instance, in seeking to rehabilitate the argument that the RAF took no interest in supporting the British army or developing its capabilities in this area, this has long been questioned by more recent studies showing the case to be far more complex and nuanced than Phillips is willing to give them credit for. Indeed, Phillips’ would have benefitted from a reading of the work of David Ian Hall or this author’s own research. The lack of engagement with such works suggests a wider lack of contextual knowledge of the inter-war period and the pressures the RAF faced regarding their survival as an independent Service.

Concerning issues related to aircraft development, an examination of the various works of Edgerton, would have aided in providing the wider context of the development of the British aircraft industry. This would allow for a greater understanding of the relationship between the Air Ministry and the aircraft industry to be explored within the book. This lack of understanding is a concern in a work of this length. For instance, the Air Ministry is criticised for its decision to continue authorising the production of obsolescent aircraft such as the Fairey Battle (p. 42). Phillips’ argument, however, does not consider the industrial problems of the British aircraft industry in enough depth to demonstrate the difficulties faced by the Air Ministry. For example, officials at the Air Ministry faced the difficult decision of whether to order aircraft from firms to retain labour and gain large-scale production experience or reduce the potential for losing skilled labour. If the latter option were chosen, the teething problems of ramping up production that had been experienced at the start of the rearmament drive would be experienced again.

Moreover, there also appears to be a further lack of specific understanding of the wider aircraft industry and the challenges the Air Ministry faced in getting aircraft through the design and development programme. This is used, again, as a stick with which to hit the Air Ministry, without taking the time to develop a more nuanced argument by considering the lead times from specifications being issued to the first production batch being delivered (p. 107). Aircraft that emerged from aircraft firms and went on to be household names during the Second World War were going through the design and development process at the time decisions were being made to expand the RAF and fall into the quantity versus quality argument that was had by those in the Air Ministry responsible for this area. Phillips is, however, correct in highlighting that this left Bomber Command with a significant capability gap from the start of the war in 1939 until the introduction of the four-engined Lancaster heavy bomber in 1941.

Combined with the issue of contextual understanding, Phillips’ work suffers from a degree of hindsight bias. Again, this bias is used to illustrate that the RAF were wrong. For example, the RAF and the wider Air Ministry are criticised for not realising the importance of the experiments being conducted by Robert Watson-Watt in developing a basic air defence system (pp. 30, 130-1). This feels like an overly harsh criticism given that the technology was being developed as decisions on arming the RAF were being made. Furthermore, a potential failure in this technology meant facing a similar problem to that of the First World War regarding advanced warning of incoming enemy aircraft.

Despite these criticisms, the chapters analysing the relationship between the wider government and the Air Ministry are the most engaging. They provide a real depth of understanding of the dynamics at play between the two. However, even here, there is a degree of reading history backwards and criticising the RAF on decisions where those looking after the event know what happened, but the protagonists do not.

As well as the areas identified above, several stylistic issues exist with the book’s structure and form. This makes gaining any momentum in the argument and analysis challenging to sustain. The book comprises 38 chapters, which, given the size of the work, means most are relatively short and jump around the topic area, thus making the overall argument and analysis challenging to follow. There is also a lack of analytical consistency tying each chapter together and a tendency to move around chronologically without setting the ideas being discussed in context, especially if they had been mentioned in previous chapters. This truncated style leaves an impression that a tighter structure would have helped with the flow of the argument and would have aided in making the links between developments clearer. In addition, a clearer statement of intent at the beginning of each chapter would have aided readers in understanding what the author wanted them to take away in terms of argument and viewpoint.

Critically, one of the significant issues with this work’s presentation is the lack of references within each chapter. Many statements lack supporting evidence (either primary or secondary), and quotes are also left unsupported. For example, chapter 2, which looks at the period when Sir Hugh Trenchard becomes Chief of the Air Staff for the second time, has only one reference, despite plentiful sources. Additionally, the primary evidence cited has been chosen to suit a particular pre-formed argument rather than the argument formed by the available evidence (of which the files in The National Archives alone are plentiful).

Overall, this attempt at post-revisionism largely fails in presenting a depth of analysis through the poor use of references and available evidence. It feels as if the author had their argument in mind before the research. The traditional bashing of the RAF of the inter-war period has yet to disappear from the annals of history.

#BookReview – Black Snow: Curtis LeMay, the Firebombing of Tokyo, and the Road to the Atomic Bomb

James M. Scott, Black Snow: Curtis LeMay, the Firebombing of Tokyo, and the Road to the Atomic Bomb. W.W. Norton: New York, NY, 2022. Hbk. 420 pp.

Reviewed by Dr Brian Laslie

There will always be an inevitable struggle between popular historians writing for the general public and academic authors whose writing is often aimed at those working in the so-called ‘ivory tower’ of academia. However, the work of academic historians inform that of popular historians whose work reaches a wider audience of readers, some of whom are thus, in turn, inspired to become academics. This was certainly how I became interested in the profession of being a historian. Nevertheless, every so often, an author comes along who is that rarest of creatures: the unicorn, or that rare writer who blends academic credentials and methodology and the ability to spin a readable tale. James Scott is that unicorn with his new book, Black Snow: Curtis LeMay, the Firebombing of Tokyo, and the Road to the Atomic Bomb. Scott, a journalist and former Nieman Fellow at Harvard University, is the author of several best-selling history books, including Rampage: MacArthur, Yamashita, and the Battle of Manila and Target Tokyo: Jimmy Doolittle and the Raid That Avenged Pearl Harbor, which was a finalist for the Pulitzer Prize in history.

The history of America’s strategic bombing during the Second World War has recently been sensationalized with the publication of Malcolm Gladwell’s The Bomber Mafia (2021). However, Black Snow is, in reality, the Bomber Mafia book you have wanted to read. Indeed, if Gladwell’s book was an appetizer, then this is the main course and dessert. Scott more fully explores the background and motivations of Generals Haywood Hansell and Curtis LeMay and, given the length of Scott’s work, produces a much more coherent explanation of how and why each man acted in accordance with their desires to end the war. Black Snow, focusing on the experience of Japan’s civilian population on the ground, is also reminiscent of Stephen Bourque’s Beyond the Beach (2018) and Richard Overy’s The Bombers and the Bombed (2014). Each of these volumes provides well-needed reminders of the horrific suffering faced by those on the receiving end of bombings. Moreover, Scott is at his best when describing the situation on the ground from the perspective of the Japanese who lived through the bombing. To achieve that end, Scott interviewed 11 survivors and spent research time at archives in the United States and the Center for the Tokyo Air Raids and War Damage, the Kyoto Museum for World Peace, and other institutions in Japan.

While other books have focused on the strategic bombing campaigns against Japan, such as Herman S. Wolk’s Cataclysm (2010), Barrett Tillman’s Whirlwind (2010), Daniel Schwabe’s Burning Japan (2015), and Kenneth Werrell’s Blankets of Fire (1996), few have done as well as Scott has in presenting a comprehensive treatment. Once again, Scott’s focus on those on the ground is where this book truly adds to the conversation and the historical record. While the morality of the bombing of Japan is not the subject of this review, and there is, again, a wide literature on the subject, Scott’s ability to detail and compare the actions of some of Japan’s citizens against those wing commander – and future commander of the United States Air Force’s Strategic Air Command – Thomas Power is thought-provoking rather one is an expert in the field or coming to this area fresh. Power called the bombing of Japan ‘the greatest show on earth’ (p. 248).

Black Snow is geared towards a wide audience and not for the expert in the field. Given this, one area where the book may be seen to fall down to those with more detailed knowledge of the subject is in the book’s biographies of Generals Henry “Hap” Arnold (pp. 13-9) and LeMay (pp. 97-109). These are slightly overextended to someone who is not approaching the subject for the first time. However, this is really a minor critique.

Overall, Black Snow is a terrific addition to the historiography of the use of air power in the Pacific War of the Second World Ward. As mentioned, the work will appeal to both buffs and scholars alike, and both will find much to engage within these pages. Black Snow is a needed addition to the conversation of what air power can and cannot do, but more importantly, what air power can do when restraints are removed and why the United States must guard against unrestricted aerial warfare in future conflicts.

Articles

Kristen Alexander and Kate Ariotti, ‘Mourning the Dead of the Great Escape: POWs, Grief, and the Memorial Vault of Stalag Luft III,’ Journal of War & Culture Studies (2022), DOI: 10.1080/17526272.2022.2097774.

In March 1944 seventy-six Allied prisoners of war escaped from Stalag Luft III. Nearly all were recaptured; fifty were later shot. This article examines what happened in the period between recapture and the interment of the dead prisoners’ cremated remains at Stalag Luft III. It positions what came to be known as ‘the Great Escape’ as an event of deep emotional resonance for those who grieved and reveals the dual narrative they constructed to make sense of their comrades’ deaths. In discussing the iconography of the vault constructed by the camp community to house the dead POWs’ ashes, this article also suggests a dissonance in meaning between that arising from personal, familial grief and the Imperial War Graves Commission’s standardised memorial practice. Focusing on the Great Escape’s immediate aftermath from the perspective of the POWs themselves provides a more nuanced understanding of the emotional impact of this infamous event.

Susan Allen, Sam Bell and Carla Machain, ‘Air Power, International Organizations, and Civilian Casualties in Afghanistan,’ Armed Forces & Society (2022), doi:10.1177/0095327X221100780.

Can the presence of international organizations reduce civilian deaths caused by aerial bombing? This commentary examines this question in the specific context of the U.S.-led war in Afghanistan. We evaluate this based on interviews conducted with members of international organizations that were present in Afghanistan during the conflict, existing intergovernmental organizations, nongovernmental organizations, and government reports, and with quantitative data on civilian casualties between 2008 and 2013. We conclude that there is tentative evidence from Afghanistan that international organizations can in fact reduce the severity of civilian killings that result from the use of air power. However, there is much need for greater data sharing to more fully answer this important question.

Derek Lutterbeck, ‘Airpower and Migration Control,’ Geopolitics (2022), DOI: 10.1080/14650045.2022.2094776.

Migration scholarship has thus far largely neglected the role of aircraft in both (irregular) migration and state policies aimed at controlling migration. Drawing inspiration from the field of strategic studies, where ‘airpower’ has been a key theoretical concept, this article explores the role of aerial assets in states’ migration control efforts. The article discusses three main dimensions of the use of airpower in controlling migration: the increasing resort to aircraft for border enforcement purposes – or what can be referred to as ‘vertical border policing’ –, states’ tight monitoring of the aerial migration infrastructure, and the use of aircraft in migrant return operations. As a core element of state power, it is airpower’s key features of reach, speed and height which have made it a particularly useful migration control instrument.

Priya Mirza “Sovereignty of the air’: The Indian princely states, the British Empire and carving out of air-space (1911–1933),’ History and Technology (2022), DOI: 10.1080/07341512.2022.2079370.

Who owns the skies? Under British colonialism, the ownership of the skies of India was a contested matter. The onset of aviation presented a challenge to the territorial understanding between the British and semi-sovereign Indian princes, Paramountcy (1858–1947). Technology itself was a tricky area: roadways, railways, telegraphs, and the wireless were nibbling away at the sovereign spheres which Paramountcy had put in place. This paper looks at the history of aviation in princely India, from aviation enthusiasts such as the rulers of Kapurthala, Jodhpur and Bikaner to subversive princes like the Maharaja of Patiala who worked towards a military air force. The paper tracks the three stages of the journey of aviation in princely India, from individual consumption, to the historical context of World War One which aided its access and usage, and finally, the collective princely legal assertion over the vertical air above them in the position, ‘sovereignty of air’. The government’s civil aviation policy in India remained ambiguous about the princes’ rights over the air till 1931 when their sovereignty of the sky was finally recognised. The paper focuses on the Indian princes varied engagement with aviation, modernity and their space in the world.

Ayodeji Olukoju ‘Creating ‘an air sense:’ Governor Hugh Clifford and the beginnings of civil aviation in Nigeria, 1919-1920,’ African Identities (2022), DOI: 10.1080/14725843.2022.2096566.

This paper focuses on the neglected subject of the beginnings of civil aviation in Nigeria in the aftermath of World War I. Until now, the literature on civil aviation in British colonial Africa had focused largely on Kenya, Central and South Africa and on post-World War II West Africa. This paper, relying on previously unexploited archival material, examines policy debates and options considered by the Colonial Office, the Air Ministry and the Nigerian colonial government. The unique, pioneering aviation drive of Nigeria’s Governor Hugh Clifford took place in the context of immediate post-World War I dynamics: economic vicissitudes, Anglo-French rivalry in West Africa and the policy interface between London and the colonies. This paper demonstrates that aviation development in Nigeria had roots in the early 1920s, and that the initiative was not a metropolitan monopoly, thereby illustrating the extent of colonial gubernatorial autonomy vis-à-vis London.

S. Seyer, ‘An Industry Worth Protecting? The Manufacturers Aircraft Association’s Struggle against the British Surplus, 1919–1922,’ Journal of Policy History 34, no. 3 (2022), pp. 403-39.

The American aircraft industry’s important role in the economic, military, and cultural expansion of the United States over the past one hundred years has been well documented by historians. But America’s twentieth century aerial dominance was not preordained. After World War I, the nascent American aircraft industry faced a concerted British effort to dump thousands of war surplus machines on the U.S. market. With aircraft outside of the nation’s tariff regime, members of the Manufacturers Aircraft Association turned to Congress for emergency protections in the face of what they considered an existential threat. Despite efforts to equate a strong industrial base for aviation with the national defense, aircraft antidumping legislation became mired in partisan debates over tariff policy and accusations of wartime corruption. In the absence of relief from Congress, the Wright patent served as a barrier against the importation of foreign surplus machines.

Ameya Tripathi, ‘Bombing Cultural Heritage: Nancy Cunard, Art Humanitarianism, and Primitivist Wars in Morocco, Ethiopia, and Spain,’ Modernist Cultures 17, no. 2 (2022), pp. 191-220.

This article examines Nancy Cunard’s later writing on Spain as a direct legacy of her previous projects as a modernist poet, publisher and black rights activist. Cunard was a rare analyst of the links between total war, colonial counter-insurgency, and cultural destruction. Noting the desire of both the air power theorist and art collector to stereotype peoples, from Morocco to Ethiopia to Spain, as ‘primitive’, the article brings original archival materials from Cunard’s notes into dialogue with her journalism, and published and unpublished poetry, to examine how she reclaimed and repurposed primitivism. Her poems devise a metonymic and palimpsestic literary geopolitics, juxtaposing fragments from ancient cultures atop one another to argue, simultaneously, for Spain’s essential dignity as both a primitive and a civilised nation. Cunard reconciles Spain’s liminal status, between Africa and Europe, to argue for Spain’s art, and people, as part of a syncretic, universal human cultural heritage, anticipating the art humanitarianism of organisations such as UNESCO.

Books

Stephen Bourque, D-Day 1944: The Deadly Failure of Allied Heavy Bombing on June 6 (Osprey: Osprey Publishing, 2022).

D-Day is one of the most written-about events in military history. One aspect of the invasion, however, continues to be ignored: the massive pre-assault bombardment by the Allied Expeditionary Air Force (AEAF), reinforced by RAF Bomber Command and the US Eighth Air Force on June 6 which sought to neutralize the German defenses along the Atlantic Wall. Unfortunately, this failed series of attacks resulted in death or injury to hundreds of soldiers, and killed many French civilians.

Despite an initial successful attack performed by the Allied forces, the most crucial phase of the operation, which was the assault from the Eighth Air Force against the defenses along the Calvados coast, was disastrous. The bombers missed almost all of their targets, inflicting little damage to the German defenses, which resulted in a high number of casualties among the Allied infantry. The primary cause of this failure was that planners at Eighth Air Force Headquarters had changed aircraft drop times at the last moment, to prevent casualties amongst the landing forces, without notifying either Eisenhower or Doolittle.

This book examines this generally overlooked event in detail, answering several fundamental questions: What was the AEAF supposed to accomplish along the Atlantic Wall on D-Day and why did it not achieve its bombardment objectives? Offering a new perspective on a little-known air campaign, it is packed with illustrations, maps and diagrams exploring in detail the features and ramifications of this mission.

Laurence Burke II, At the Dawn of Airpower: The U.S. Army, Navy and Marine Corps’ Approach to the Airplane 1907–1917 (Annapolis, MD: Naval Institute Press, 2022).

At the Dawn of Airpower: The U.S. Army, Navy, and Marine Corps’ Approach to the Airplane, 1907-1917 examines the development of aviation in the U.S. Army, Navy, and Marine Corps from their first official steps into aviation up to the United States’ declaration of war against Germany in April, 1917. Burke explains why each of the services wanted airplanes and show how they developed their respective air arms and the doctrine that guided them.   His narrative follows aviation developments closely, delving deep into the official and personal papers of those involved and teasing out the ideas and intents of the early pioneers who drove military aviation   Burke also closely examines the consequences of both accidental and conscious decisions on the development of the nascent aviation arms.  

Certainly, the slow advancement of the technology of the airplane itself in the United States (compared to Europe) in this period affected the creation of doctrine in this period.  Likewise, notions that the war that broke out in 1914 was strictly a European concern, reinforced by President Woodrow Wilson’s intentions to keep the United States out of that war, meant that the U.S. military had no incentive to “keep up” with European military aviation.  Ultimately, however, he concludes that it was the respective services’ inability to create a strong, durable network connecting those flying the airplanes regularly (technology advocates) with the senior officers exercising control over their budget and organization (technology patrons) that hindered military aviation during this period.

Jim Leeke, Turtle and the Dreamboat: The Cold War Flights That Forever Changed the Course of Global Aviation (Dulles, VA: Potomac Books, 2022).

The Turtle and the Dreamboat is the first detailed account of the race for long-distance flight records between the U.S. Army and U.S. Navy less than fourteen months after World War II. The flights were risky and unprecedented. Each service intended to demonstrate its offensive capabilities during the new nuclear age, a time when America was realigning its military structure and preparing to create a new armed service – the United States Air Force.

The first week of October 1946 saw the conclusion of both record-breaking, nonstop flights by the military fliers. The first aircraft, a two-engine U.S. Navy P2V Neptune patrol plane nicknamed the Truculent Turtle, flew more than eleven thousand miles from Perth, Western Australia, to Columbus, Ohio. The Turtle carried four war-honed pilots and a young kangaroo as a passenger. The second plane, a four-engine U.S. Army B-29 Superfortress bomber dubbed the Pacusan Dreamboat, flew nearly ten thousand miles from Honolulu to Cairo via the Arctic. Although presented as a friendly rivalry, the two flights were anything but collegial. These military missions were meant to capture public opinion and establish aviation leadership within the coming Department of Defense.

Both audacious flights above oceans, deserts, mountains, and icecaps helped to shape the future of worldwide commercial aviation, greatly reducing the length and costs of international routes. Jim Leeke provides an account of the remarkable and record-breaking flights that forever changed aviation.

Micheal Napier, Flashpoints: Air Warfare in the Cold War (Oxford: Osprey Publishing, 2022).

The Cold War years were a period of unprecedented peace in Europe, yet they also saw a number of localised but nonetheless very intense wars throughout the wider world in which air power played a vital role. Flashpoints describes eight of these Cold War conflicts: the Suez Crisis of 1956, the Congo Crisis of 1960-65, the Indo-Pakistan Wars of 1965 and 1971, the Arab-Israeli Wars of 1967 and 1973, the Falklands War of 1982 and the Iran-Iraq War of 1980-88. In all of them both sides had a credible air force equipped with modern types, and air power shaped the final outcome.

Acclaimed aviation historian Michael Napier details the wide range of aircraft types used and the development of tactics over the period. The postwar years saw a revolution in aviation technology and design, particularly in the fields of missile development and electronic warfare, and these conflicts saw some of the most modern technology that the NATO and Warsaw Pact forces deployed, alongside some relatively obscure aircraft types such as the Westland Wyvern and the Folland Gnat.

Highly illustrated, with over 240 images and maps, Flashpoints is an authoritative account of the most important air wars of the Cold War.

David Nicolle and Gabr Ali Gabr, Air Power and the Arab World – Volume 6: World in Crisis, 1936-March 1941 (Warwick: Helion and Company, 2022).

Volume 6 of the Air Power and the Arab World mini-series continues the story of the men and machines of the first half century of military aviation in the Arab world. These years saw the Arab countries and their military forces caught up in the events of the Second World War.

For those Arab nations which had some degree of independence, the resulting political, cultural and economic strains had a profound impact upon their military forces. In Egypt the Army generally remained quiet, continuing with its often unglamorous and little appreciated duties. Within the Royal Egyptian Air Force (REAF), however, there were a significant number of men who wanted to take action in expectation of what they, and many around the world, expected to be the defeat of the British Empire.

The result was division, widespread mistrust, humiliation, and for a while the grounding of the entire REAF. In Iraq the strains of the early war years sowed the seeds of a yet to come direct armed confrontation with the British.

Volume 6 of Air Power and the Arab World then looks at the first efforts to revive both the REAF and the Royal Iraqi Air Force (RIrAF), along with events in the air and on the ground elsewhere in the Arab world from 1939 until March 1941.

This volume is illustrated throughout with photographs of the REAF, RIrAF and RAF and a selection of specially commissioned colour artworks.

Adrian Phillips, Rearming the RAF for the Second World War: Poor Strategy and Miscalculation (Barnsley: Pen and Sword, 2022).

When the RAF rearmed to meet the growing threat from Nazi Germany’s remorseless expansion in the late 1930s, it faced immense challenges. It had to manage a huge increase in size as well as mastering rapid advances in aviation technology. To protect Britain from attack, the RAF’s commanders had to choose the right strategy and the right balance in its forces. The choices had to be made in peacetime with no guidance from combat experience. These visions then had to be translated into practical reality. A shifting cast of government ministers, civil servants and industrialists with their own financial, political and military agendas brought further dynamics into play. The RAF’s readiness for war was crucial to Britain’s ability to respond to Nazi aggression before war broke out and when it did, the RAF’s rearmament was put to the acid test of battle. Adrian Phillips uses the penetrating grasp of how top level decisions are made that he honed in his inside accounts of the abdication crisis and appeasement, to dissect the process which shaped the RAF of 1940. He looks beyond the familiar legends of the Battle of Britain and explores in depth the successes and failures of a vital element in British preparations for war.

John Quaife, Battle of the Atlantic: Royal Australian Air Force in Coastal Command 1939-1945 (Newport, NSW: Big Sky Publishing, 2022).

At the outbreak of World War II, somewhat by accident — and just as the first shots of the war were fired — young Australian airmen from the Royal Australian Air Force were engaged in operations that would become known collectively as the Battle of the Atlantic. Arguably lesser-known than air campaigns in other theatres, large numbers of Australians who volunteered for service with Royal Australian Air Force, found themselves fighting in this battle. Australians were there at the outbreak and many would go on to fly some of the final missions of the war in Europe.

This book captures some of the experiences of the Royal Australian Air Force members who served with Coastal Command and, through the weight of numbers alone, stories of the Sunderland squadrons and the Battle of the Atlantic dominate the narrative. Being critical to Britain’s survival, the battle also dominated Coastal Command throughout the war but Australians served in a surprising variety of other roles. The nature of many of those tasks demanded persistence that could only be achieved by large numbers of young men and women being prepared to ‘do what it took’ to get a tedious and unrewarding job done. Over 400 did not come home.

Steven Zaloga, The Oil Campaign 1944–45: Draining the Wehrmacht’s Lifeblood (Oxford: OIsprey Publishing, 2022).

With retreating German forces losing their oilfields on the Eastern Front, Germany was reliant on its own facilities, particularly for producing synthetic oil from coal. However, these were within range of the increasingly mighty Allied air forces. In 1944 the head of the US Strategic Air Forces, General Carl Spaatz was intent on a new campaign that aimed to cripple the German war machine by depriving it of fuel.

The USAAF’s Oil Campaign built up momentum during the summer of 1944 and targeted these refineries and plants with its daylight heavy bombers. Decrypted German communications made it clear that the Oil Campaign was having an effect against the Wehrmacht. Fuel shortages in the autumn of 1944 forced the Luftwaffe to ground most of its combat units except for fighters involved in the defense of the Reich. Fuel shortages also forced the Kriegsmarine to place most of its warships in harbor except for the U-boats and greatly hampered German army campaigns such as the Battle of the Bulge in December 1944-45.

This fascinating book packed with key photos and illustrations examines the controversies and debates over the focus of the US bombing campaign in the final year of the war, and the impact it had on the war effort overall.

The British Strategic Air Offensive against Germany (SAOG) and the Allied Combined Bomber Offensive (CBO) remain contentious and divisive areas of debate within the historiography of the Second World War and the development of air power, respectively. Essentially the central debate on the bomber offensive has been polarised between discussing the exigencies of military effectiveness – the contribution the campaign made to the overall war effort – and the philosophical view that it was a morally reprehensible act.[1] More recently, the historiographical trend has shifted towards understanding the impact that bombing had upon civilian populations.[2] Into this field in 2012 came a new and important work by Peter Gray that examined the conduct of the SAOG innovatively, namely through a deep understanding of the role of strategic leadership in war and its relationship with the legality and legitimacy of the bombing campaign against Germany.

Gray’s book focuses on strategic leadership and the interface between key senior leaders involved in the direction of the bomber offensive against Germany. Leadership remains an often discussed but little understood area of study within military history. As a result, books are replete with inadequate or ineffective leadership claims without understanding the factors underpinning it and how it interacts with operations. Nevertheless, effective leadership remains the key to understanding military performance at all levels of war.

Gray’s professional experience both as a senior officer in the RAF – he retired as an Air Commodore – and in academia meant that he was well equipped to write this book and the PhD on which it is based. While at the time of writing, Gray is a Professor of Air Power Studies at the University of Wolverhampton; he was previously the Royal Aeronautical Society’s Senior Research Fellow in Air Power Studies at the University of Birmingham and is an acknowledged expert in air power studies and leadership. Before he retired from the RAF, Gray served in several important positions, including Director of Defence Studies (RAF) at the Joint Services Command and Staff College and as Director of the Defence Leadership and Management Centre. However, that Gray is a retired officer does not affect his objectivity towards the subject he studies. Indeed, while it can be easy to suggest that retired senior officers often suffer from what might be described as cultural blindness towards the subjects they write on, this is not the case with Gray, as evidenced by his analysis of the role of Marshal of the Royal Air Force (MRAF) Sir Arthur Harris noted below.

Gray’s work used an interdisciplinary approach grounded in an understanding of leadership theory to examine the direction of the bomber offensive. Utilising his extensive background in the military and his teaching and writing about the subject, Gray explored some of the theoretical aspects of leadership while making it clear that leadership is both complex and ambiguous at the senior/strategic level. For example, in examining the interface between the relationship of the Air Officer Commander-in-C of RAF Bomber Command, Air Chief Marshal Sir Arthur Harris, and the RAF’s Air Staff, in particular Harris’ relationship with the Chief of the Air Staff (CAS), MRAF Sir Charles Portal, it is evident that numerous factors related to the complexity of ambiguity of senior leadership influenced the conduct of SOAG. These factors included relationships with allies, operational commanders, inter-service rivalry, and moral and ethical considerations. Harris does not emerge from this analysis well, with, for example, Gray describing him as ‘naïve’ to expect the lion’s share of the national resources for the bomber offensive. In addition, Harris struggled to ‘accept the vicissitudes of coalition warfare’. Nevertheless, Gray does admit that Harris operated within a problematic area where the ‘operational and strategic levels’ overlapped (p. 291).

There are numerous reasons why Harris arguably struggled in looking up and outside of his operational silo. However, as Gray lamented, Portal probably regretted that Harris never went to the RAF Staff College at Andover and instead attended the British Army’s Staff College at Camberley (p. 43). This is an important cultural point that still requires further examination. Nevertheless, while Harris has often been portrayed as the archetypal advocate of the RAF’s perceived singular focus on bombing in his development as a leader, he lacked the intellectual underpinnings that most future senior RAF commanders shared: attendance at Andover. It should, however, be noted that his attendance at Camberley also illustrated that he was well regarded in the RAF as students attending the other service Staff College’s also acted as representatives of their parent services and sought to inform fellow students about their work. Also, unlike many of his contemporaries operating at the senior level, including Portal, Harris never attended the Imperial Defence College (IDC), where he would have learned to speak the language of a combined military.

Another example of Harris’ inability to look up and out of his silo concerns the debates over relations with the other services. While Harris issued directives and loyally carried out orders, he often soured relations with a poor choice of language for a senior leader. The use of terms such ‘oily boys’ did not aid him or the Air Staff’s ability to explain complicated arguments over the effectiveness of air power to both colleagues within other services and politicians and allies (pp. 255-7). These leadership challenges were a key issue throughout 1944, especially in the lead up to Operation OVERLORD (pp. 215-28). Nevertheless, a vital problem for senior leaders is the maintenance of vision and purpose for an organisation in the face of the leadership challenges that faced both Harris and the Air Staff. Maintaining this vision and purpose had implications for the direction of the bomber offensive.

Marshal, Admiral W.D. Leahy, Admiral E.J. King, and Captain Forrest B. Royal (Source: © IWM A 18825)

In comparison to Harris, the RAF was fortunate that, in Portal, they had a CAS who had the vision and ability to see the organisation’s central purpose through to fruition. Portal managed the shift to area bombing, and he was able to work well with both politicians and allies alike. However, Portal was perhaps aided in his work given that his key ally, the United States Army Air Force, placed as much importance as the RAF did on the bomber. However, the decision by the Combined Chiefs of Staff to place Portal in charge of the strategic direction of the Combined Bomber Offensive at the Casablanca Conference of January 1943 (p. 211) highlighted not only an indication of his abilities as a senior leader but also his standing amongst his peers. Unlike Harris, Portal was able to look up and out of his silo and interface with ‘the various organizations that contribute[d] to the greater enterprise […] across the range of Whitehall and into international arenas’ (p. 291).

Gray’s discussion of legitimacy is useful as it helps set the context for the conduct and direction of the bomber offensive and the challenges that confronted the RAF’s senior leadership during the Second World War. The interwar period saw significant discussions over air power in modern warfare. It also saw attempts to codify and limit its role through international law. While the Hague Conference of 1923 produced a report on the Rules of Aerial Warfare with genuine humanitarian intentions, it was not ratified by the nations involved. The attempt to codify laws relating to the use of air power failed most significantly at the Geneva Disarmament Conference, 1932-33. Nevertheless, this failure to agree did not mean that the RAF ignored the implications of the ethics of air power when formulating doctrine and strategy. However, beyond legal discussions, there was, as Gray argued, little in the way of contemporary philosophical debate over war in general. Indeed, the historiography concerning anti-war movements in the interwar period is ‘muddled at best’, thus raising significant questions over interpretations, such as Grayling’s (p. 48).

For Gray, the most influential writer in this period regarding issues surrounding legitimacy and international law was the jurist J.M Spaight (pp. 54-7). The reason for Spaight’s importance stems from his relationship with MRAF Sir Hugh Trenchard during his tenure as CAS, his standing within the Air Ministry and perhaps most importantly, the simple fact that his voluminous works appeared on the reading list for Andover, where future leaders would have been exposed to his writings. Although Gray does not make this point, Spaight wrote for the Royal Air Force Quarterly in the 1930s. This would have seen a broader audience in the RAF exposed his work, though the question remains how much journals such as the Quarterly were read beyond those attending Staff College.[3]

The failure to gain effective international agreement over the use of air power in war led Spaight to note that inevitably ‘cities would be bombed’ (p. 57). Similar ideas pervaded the development of air power doctrine but did not mean that other areas of operations were ignored. The focus on bombing was the logical development of an inherently offensive weapons system. When applied in the strategic sense, the application of bombing was going to raise moral issues. However, the British had a tradition of utilising its other strategic arm, the Royal Navy, to bombard and blockade so that the use of the British Army in continental warfare could be ‘sidestepped’ (p. 59). This, coupled with ineffective international control concerning the laws of war, allowed for the development of an offensively minded doctrine.

Moreover, this did not mean, as Spaight’s own writings indicated, that there was no desire to fight the war as humanely as possible. However, there was a realisation amongst the Air Staff that, as Gray has written elsewhere, ‘The Gloves Will Have to Come Off’ (p. 57).[4] This had clear operational implications for the conduct of the bomber offensive when the decision was taken to shift to both night attacks and area bombing. However, it should be seen as an incremental shift and not the obvious solution as traditionally portrayed. Nonetheless, questions over the humane use of strategic air power became acutely apparent in 1945 when the Prime Minister, Winston Churchill, began to distance himself from the campaign after the raid on Dresden. Concerning this episode, Grey argues it had a degree of logic to it but must be placed within the context of being aware of the growing resilience of Germany’s military in the face of allied advances, and that the Air Staff argued that an early end to the bomber offensive might cause the loss of more lives in the long-term (p. 228).

Overall, this excellent book adds a fresh perspective to a well-trodden path in the historiography of the Second World War. Gray makes clear that before any evaluation can be made on the key areas that have occupied historians of the bomber offensive, namely the issues of effectiveness and morality; we must understand the challenges that confronted those responsible for its conduct and how they sought to deal with the ambiguities and complexities of senior leadership under the stress and strain of global conflict. It also illustrates that historians should not be afraid to learn from allied disciplines. In understanding alternative methodologies, we can bring new light to old subjects.

[1] The view that bombing was morally reprehensible can be summarised by the work of A.C. Grayling. However, this work should be treated with care given the author’s clear lack of understanding of how both the SAOG and CBO were conducted. See A.C. Grayling, Among the Dead Cities: Is the Targeting of Civilians in War ever Justified?, Paperback Edition (London: Bloomsbury, 2007). Within the debate over the effectiveness of the CBO there are several continuing debates on themes such as the question of the bombing techniques employed by the RAF and the USAAF as well as the contribution made by the campaign in achieving air superiority over Europe before Operation OVERLORD. A key work on the debate over precision versus area bombing remains W. Hays Park, “Precision’ and ‘Area’ Bombing: Who did which, and when?,’ Journal of Strategic Studies 18, no. 1 (1995), pp. 145-74. For an examination of the role played in achieving air superiority over Europe, see: Stephen McFarland and Wesley Phillips Newton, To Command the Sky: The Battle for Air Superiority Over Germany, 1942-1944 (Washington DC: Smithsonian Institution Press, 1991). For a discussion of how RAF Bomber Command sought to overcome some of the challenges it faced with reference to the use of operational research techniques, see: Randall Wakelam, The Science of Bombing: Operational Research in RAF Bomber Command (Toronto: University of Toronto Press, 2009).

During the Second World War, many allied air crews were shot down over Europe. Some escaped, some were captured, but many others became victims of Lynchjustiz (lynch justice) by Germans. These lynchings were committed not just by Nazi officials, but civilians as well, as Nazi propaganda emphasized the air war. Dr Kevin Hall, the author of of recent book on the subject, Terror Flyers: The Lynching of American Airmen in Nazi Germany (2021), joins us for a look at this difficult topic.

Dr Kevin T. Hall is a postdoctoral researcher at the Ruhr-Universtiät Bochum, Germany. He was a Fulbright grantee in Cologne in 2013–2014 and obtained his PhD from Central Michigan University in 2018. In 2019, he was a postdoctoral research historian at the Defense Prisoner of War/Missing in Action Accounting Agency (DPAA) in Honolulu, where he assisted the agency in accounting for US servicemen missing from past conflicts.

#HistoricBookReview – The Air War, 1930-1945

Richard J. Overy, The Air War, 1930-1945. Potomac Edition. Washington DC: Potomac Books, 2005. Appendices. Tables. Photographs. Notes. Bibliographic Note. Bibliography. Index. vii + 267 pp.

Reviewed by Ryan Clauser

Few historical works have altered the course of a field of study in the way Richard Overy’s The Air War, 1939-1945 did when it was first published in 1980. When the book was published initially, air power history, as a field of academic study, was in its infancy and had been mainly regarded as the ‘Cinderella’ of military history (p. 240). However, Overy’s work transformed the historiography of air power history with his comparative study of the most important air forces of the Second World War.

The importance of Overy’s The Air War is hard to overstate, especially as the book has been reprinted twice in 1987 and 2005. In the most recent edition, that under reviewe here, Overy, now an Honorary Professor at the University of Exeter in the UK, provided the reader with new additions in the form of new statistical figures, updated research, and notes from the author. These new additions illustrate Overy’s dedication to his work and has helped keep The Air War an essential source for historians and remains one of the premier air power history texts. Since the publication of the first edition of The Air War, Overy has continued to write extensively about air power history and the history of the Second World War, including works such as Why the Allies Won (1995), The Battle of Britain: Myth and the Reality (2001), Interrogations: The Nazi Elite in the Allied Hands, 1945 (2001), The Bombing War: Europe 1939-1945 (2013) and most recently Blood and Ruins: The Great Imperial War, 1931-1945 (2021). Potomac Books published the latest edition of The Air War as part of their Cornerstones of Military History collection.

Overy starts his work by proclaiming that ‘this is not a ‘blood and guts’ book about the air war’ (p. xiii), but rather a study that aims to compare and contrast the air forces of the warring nations along with their preparations, strategies, leadership, economics, and development. The Air War sought to provide a greater overview and understanding of the discrepancies between Allied and Axis air forces and fully explain air power’s role throughout the war.

The Air War begins with an overview of each combatant nation’s preparations for war and their overall use of air power. Overy wrote that air power theory and doctrine had matured in the years leading up to and throughout the Second World War. These new ideas stated that air power could be used in many ways, such as: protecting naval power, close air support, strategic bombing, and air defence. For example, naval aviation was invaluable for Japan as the Imperial Japanese Navy used it to develop carrier strike forces. The development of Japanese naval air power sought to offset the advantages that western navies, such as the United States and Great Britain, held over Japan. However, for other Axis nations, naval air power was non-existent as Germany and Italy saw no merit in committing resources to build aircraft carriers. Instead, Germany and Italy subscribed to the theory that air power was best suited for a role in supporting their armies. However, the Allies crafted their air power doctrine more holistically to encompass all aspects of military aviation, including naval support, support of armies, strategic bombing, and aerial defence, all of which played critical roles in the Allied air war.

Overy breaks down the Second World War by year and the theatre of operation beginning with the early War in Europe spanning from 1939 to 1941. This section discusses Germany’s and the Axis’ initial success with close air support and air interdiction. However, Germany’s victories were quickly halted following the fall of France and the beginning of the Battle of Britain. Left as the only attacking force capable of striking the United Kingdom from occupied France, the Luftwaffe found itself in a role for which it was wholly unprepared. In contrast, the British utilised a far more general strategy to successfully defend their nation and launch a strategic bombing campaign of their own. Overy stated that, ‘the German rejection of a more general air strategy coincided with shifts in the war itself that made such a strategy more rather than less necessary’ (p. 37). While the air war was still an essential facet of the Second World War in its first two years, it had yet to fully mature on the battlefield.

For the rest of the war in Europe, 1941 to 1945, Overy explains how the allies’ general air strategy put them at a far more significant advantage in the air war compared to their Axis counterparts. As described by Overy, this generalist strategy allowed the allies to combine the many facets of air power, including aerial defence, ground and naval support, and strategic bombing, into one encompassing approach to the war in the air. This perspective also helped mature the Allies use of air power throughout the war. Further, the economics of the air war is also stressed. As Overy pointed out, the United States alone had seen a steady increase in aircraft production every year since 1942, and by 1944 they were outproducing Germany at a rate of nearly three to one in aircraft. Additionally, the Americans suffered less than half the losses of the Germans in the air throughout the war. These factors combined led the allies to victory in the air war and the war in general.

The war in the Pacific was strategically a much different conflict than the one in Europe. Japan’s approach to air power was to use it mainly as a supporting arm of its navy to create a multi-faceted naval strike force. Japan used their war with China to hone this strategy and their aviation technology. This early period of war for Japan allowed them to create a superior fighter aircraft in the Mitsubishi A6M Zero and allowed them to hold the upper hand for a time in their war against the United States and Great Britain following the attack on Pearl Harbor. As the war in the Pacific persisted, the Allies again found multiple roles for airpower and again committed to a generalist strategy in the east. Continuously, like the war in Europe, economics played an essential role in the Pacific, as even by 1941, Japan had begun realising that their economy was in short supply of the raw materials needed to fight a war. This hampered the Japanese war effort and nearly crippled its ability to produce aircraft. By the end of the war, Japan’s aircraft industry could barely replace what was being lost in combat, while the Americans kept producing increasingly better aircraft at staggeringly higher rates. Again, Overy emphasises that the Allied generalist strategies and superior economies were able to win the air war in the east.

While strategy and economics are at the heart of Overy’s work, he also delved into other aspects of the air war, including leadership, training, organisation, science, and research of each nation’s air force, all of which played a crucial role in the air war at large. Each of these additional factors was eventually influenced at some juncture in the war by the strategy and economics of each nation and how they chose to operate their air forces. Nonetheless, each of these additional factors played a significant role in the air war of the Second World War.

Throughout the course of Overy’s research, he relied heavily on official documents, public records, and memoirs of pilots, military commanders, and government officials. Overy was also fortunate to have access to various German records housed with the Imperial War Museum in London while researching the book in the 1970s. That said, while access to some sources was abundant, others, specifically those dealing with the Soviet Air Force, were scant at best and were limited to what the Soviet government saw fit to publish. Another issue in researching this project was the state of air power scholarship, which was in its infancy. Due to this, Overy was forced to depend on more general studies of aircraft, economics, and World War II for secondary sources. A problem that the publication of the book itself began to rectify. Overy also admits that he utilised fictional and popular publications to get a well-rounded perspective of the air war but did not include these works among his cited sources.

In this new edition, Overy has added a new preface in which he claims to have changed very little of his original text, but instead focused his edits on updating the charts and statistics. These illustrations show how economics influenced the air war and exhibit the discrepancies in how Allied and Axis powers produced aircraft. Also, in this newest edition, Overy included a valuable bibliographic note in which he evaluated the development of the historiography of air power and provided the authors and titles of works that have extrapolated further on the ideas laid out in the original Air War text such as tactics and leaderships and economics. Notably, among these works are Richard Davis’s Carl A. Spaatz and the Air War in Europe (1992), John Gooch’s collection of essays Airpower: Theory and Practice (1995), and John Buckley’s Air Power in the Age of Total War (1999). This section was not meant for Overy to vaunt his own influence on the field, but rather to provide readers with a greater historiographic picture of Second World War air power scholarship and show how the field has grown since 1980.

To describe The Air War as notable would be an understatement, as Overy took on the monumental task of comparing and contrasting the primary air forces of the Axis and Allied powers of the Second World War. Even from the outset of this book Overy admitted that he only spent paragraphs on what could be volumes worth of work, yet he was still somehow able to distil mass amounts of information and statistics into only 211 pages of content. From these pages, Overy concluded that the allies were able to gain the upper hand and win the air war largely because of their generalist strategic approach and superior economies. In totality, Overy’s The Air War is still among the preeminent air power works and should continue to be heralded for ushering air power history into the mainstream of academic study.

John Alexander, ‘The Worsted Manufacturer, Roderick Hill and ‘the most courageous decision of the War’: The Decision to Reorganise Britain’s Air Defence to Counter the V-1 Flying Bomb,’ RAF Air and Space Power Review 23, no. 1 (2021).

The first four V-1 flying bombs crossed the Channel in the early hours of 13 June 1944, exactly one week after D-Day; none were engaged and one reached Bethnal Green killing four people. When overnight 15/16 June the German Air Force launched 244 V-1s against London, the long-planned British counter V-1 defences, consisting of fighter, gun and balloon belts, brought down only thirty-three V-1s, including eleven shot-down by anti-aircraft (AA) guns, and seventy landed on London. This paper explores the decision to reorganise Britain’s Air Defence during this crucial stage of the War.

On 7 September 1933, military officers of the Italian Air Force led by Colonel Roberto Lordi departed from Naples to reach China with the task, agreed upon by Italian fascist and Chinese nationalist governments, of building a factory assembling Italian-made aircraft and training pilots for the Republic of China. The mission was stationed at Nanchang, in today’s Jiangxi province. The initiative was developed in competition with a similar American mission, which had operated since 1932 in Hankou, in the Hubei province, at the time led by Colonel John H. Jouett. The Italian government won Chiang’s attention with the agreement to use the military airfield and Italian aircraft against the Communist resistance, which pleased the expectations of the Generalissimo. In April 1934, the headquarters of the Chinese military aviation finally moved to Nanchang. The mission’s commander, Roberto Lordi, was promoted Brigadier General of the Italian Royal Air Force and appointed Chief of Staff of the Chinese Air Force. This article presents, through extensive use of unpublished private and public archive documents, the controversial history of the Italian military mission and unveils the circumstances that changed the fortune of that successful story, as well as the career and personal life of its commander.

Steven Paget, ‘The ‘Eeles Memorandum’: A Timeless Study of Professional Military Education,’ RAF Air and Space Power Review 23, no. 1 (2021).

Examinations of historical examples are an important element of the professional military education debate and demonstrate the enduring nature of some of the necessary considerations. Air Commodore Henry Eeles, the Commandant of Royal Air Force (RAF) College Cranwell between August 1952 and April 1956 wrote a prescient report in 1955. The military, political and social changes that were occurring have some parallels to the contemporary context, including expectations about access to higher education and the introduction of new technology, which was viewed as leading to an era of so-called ‘push button warfare’. Eeles was also cognisant of issues such as balance, time and life-long learning that are just as pertinent today as in 1955. The context and content of the report has ensured that it has enduring relevance for the RAF.

Matthew Powell, ‘Royalties, Patents and Sub-Contracting: The Curious Case of the Hawker Hart,’ RAF Air and Space Power Review 23, no. 1 (2021).

Aircraft procurement by the Air Ministry in the inter-war period was beset by various problems, with numerous solutions proposed in an attempt to resolve them. One such potential solution was the proposal to sub-contract the production to other aircraft manufacturers within the Air Ministry’s ring of firms who were allocated firm orders. This action by the Air Ministry, it was believed, would spread the technical knowledge of aircraft production to a wider base that could be built upon in a time of national emergency or war. This approach was also a way of ‘artificially’ keeping firms alive where they had been unsuccessful in being awarded contracts. Such a scheme would, from the industry’s perspective, however, lead to less orders for firms successful in aircraft design and allow the potential sharing of industry secrets amongst direct competitors.

Richard Worrall, “Bumps along “The Berlin Road”’: Bomber Command’s forgotten Battle of Hanover, September-October 1943,’ RAF Air and Space Power Review 23, no. 1 (2021).

The many accounts on RAF Bomber Command follow the usual chronology of the ‘Main Offensive’ against Germany throughout 1943/4, with a linear progression from the Battle of the Ruhr, to the Battle of Hamburg, to the Battle of Berlin. Yet adopting this approach is problematic. The Battle of Berlin was halted by Harris in mid-September only to be recommenced in mid-November, but it, therefore, begs the simple question: what was Bomber Command doing during the interim ten weeks? Harris’ force was far from inactive during this time, in which the centrepiece was the ‘Battle of Hanover’ that comprised four heavy-attacks in twenty-six days. This article identifies what happened during this period of the ‘Main Offensive’, to suggest why this ‘bomber battle’ has remained forgotten, highlighting how Bomber Command’s experiences over Hanover revealed its limitations at this critical stage of the bombing war.

On 20 April 1941, a group of distinguished Americans headed by the US Ambassador to the United Kingdom, John Winant, and which included Major General Henry ‘Hap’ Arnold, Chief of the US Army Air Corps, visited the de Havilland Aircraft Company’s airfield at Hatfield, England.

The party was there ostensibly to gain an insight into how various US aircraft supplied to Britain were performing, as well as to observe some of the latest British products being put through their paces. The eighteen types on display included both US and British bombers and fighters. But the star of the day was undoubtedly the de Havilland Mosquito.

Having first flown only a few months earlier, on 25 November 1940, the aircraft that was put through its paces was flown by none other than Geoffrey de Havilland. Striving to impress the trans-Atlantic visitors, de Havilland provided an outstanding display of speed and manoeuvrability. It was a routine that impressed the Americans and left them in no doubt as to the Mosquito’s abilities.

Though the visitors harboured doubts about an aircraft made of wood, they returned to the United States with full details of the design. The Mosquito had also caught the eye of Elliott Roosevelt, son of the US President and a serving officer in the USAAC. An early specialist in military aerial mapping and reconnaissance, ‘ER’ swiftly realized the value of the Mosquito in the reconnaissance role and began lobbying vigorously for its acquisition. The Air Ministry duly noted ‘ER’s’ interest and influence.

Following America’s entry into the war, formal requests for Mosquitoes began in earnest in 1942. Initial deliveries for evaluation purposes in the United States soon followed in June 1943, the aircraft initially being supplied by de Havilland Canada. From February 1944 a steady flow of the photographic reconnaissance version, from Hatfield, were provided to what would become the USAAF’s 25th Bomb Group at Watton, England. There they served with distinction in a variety of specialist roles, including day and night photography, weather reconnaissance, ‘chaff’ (Window) dropping, scouting for the bomber force, raid assessment, and filming of special weapons projects.

A number of these Mosquitoes, serving with the 492nd Bomb Group at Harrington, were involved in the so-called ‘Joan-Eleanor’ project, working with OSS secret agents on the Continent. Finally, in 1945, the USAAF received much-anticipated night fighter Mosquitoes which enjoyed combat success with the 416th Night Fighter Squadron in Italy.

In this highly illustrated work, the author explores the full story of why the Americans wanted Mosquitoes, how they went about obtaining them, and their noted success and popularity with USAAF units.

Michael Hankins, Flying Camelot: The F-15, the F-16, and the Weaponization of Fighter Pilot Nostalgia (Ithaca, NY: Cornell University Press, 2021).

Flying Camelot brings us back to the post-Vietnam era, when the US Air Force launched two new, state-of-the art fighter aircraft: the F-15 Eagle and the F-16 Fighting Falcon. It was an era when debates about aircraft superiority went public—and these were not uncontested discussions. Michael W. Hankins delves deep into the fighter pilot culture that gave rise to both designs, showing how a small but vocal group of pilots, engineers, and analysts in the Department of Defense weaponized their own culture to affect technological development and larger political change.

The design and advancement of the F-15 and F-16 reflected this group’s nostalgic desire to recapture the best of World War I air combat. Known as the “Fighter Mafia,” and later growing into the media savvy political powerhouse “Reform Movement,” it believed that American weapons systems were too complicated and expensive, and thus vulnerable. The group’s leader was Colonel John Boyd, a contentious former fighter pilot heralded as a messianic figure by many in its ranks. He and his group advocated for a shift in focus from the multi-role interceptors the Air Force had designed in the early Cold War towards specialized air-to-air combat dogfighters. Their influence stretched beyond design and into larger politicized debates about US national security, debates that still resonate today.

A biography of fighter pilot culture and the nostalgia that drove decision-making, Flying Camelot deftly engages both popular culture and archives to animate the movement that shook the foundations of the Pentagon and Congress.

Norman Ridley, The Role of Intelligence in the Battle of Britain (Barnsley: Pen and Sword, 2021).

The Battle of Britain was fought between two airborne military elites and was a classic example of pure attack against pure defence. Though it was essentially a ‘war of attrition’, it was an engagement in which the gathering, assessment and reaction to intelligence played a significant role on both sides.

In some respects, both the RAF and the Luftwaffe were hamstrung in their endeavours during the Battle of Britain by poor intelligence. The most egregious Luftwaffe blunder was its failure to appreciate the true nature of Fighter Command’s operational systems and consequently it made fundamental strategic errors when evaluating its plans to degrade them. This was compounded by the Luftwaffe’s Intelligence chief, Major Josef ‘Beppo’ Schmid, whose consistent underestimation of Fighter Command’s capabilities had a huge negative impact upon Reichsmarschall Göring’s decision-making at all stages of the conflict.

Both the Luftwaffe and the RAF lacked detailed information about each other’s war production capacity. While the Luftwaffe did have the benefit of pre-war aerial surveillance data it had been unable to update it significantly since the declaration of war in September 1939. Fighter Command did have an distinct advantage through its radar surveillance systems, but this was, in the early stages of the conflict at least, less than totally reliable and it was often difficult to interpret the data coming through due to the inexperience of many of its operators. Another promising source of intelligence was the interception of Luftwaffe communications.

It is clear that the Luftwaffe was unable to use intelligence as a ‘force multiplier’, by concentrating resources effectively, and actually fell into a negative spiral where poor intelligence acted as a ‘force diluter’, thus wasting resources in strategically questionable areas. The British, despite being essentially unable to predict enemy intentions, did have the means, however imperfect, to respond quickly and effectively to each new strategic initiative rolled out by the Luftwaffe.

The result of three years intensive research, in this book the author analyses the way in which both the British and German Intelligence services played a part in the Battle of Britain, thereby attempting to throw light on an aspect of the battle that has been hitherto underexposed to scrutiny.

Stephen Wynn, Hitler’s Air Defences (Barnsley: Pen and Sword, 2021).

The first Allied bombing raid on Berlin during the course of the Second World War, took place on 7 June 1940, when a French naval aircraft dropped 8 bombs on the German capital, but the first British raid on German soil took place on the night of 10/11 May 1940, when RAF aircraft attacked Dortmund.

Initially, Nazi Germany hadn’t given much thought about its aerial defences. being attacked in its ‘own back yard’ wasn’t something that was anticipated to be an issue. Germany had been on the offensive from the beginning of the war and Hitler believed that the Luftwaffe was the much stronger air force.

In addition, from 1939-1942, the Allied policy of aerial attacks on German soil was to hit targets with a distinct military purpose, such as munitions factories, airfields etc. This meant that the Germany military could focus where they placed their anti-aircraft batteries and had a very good idea of how many they would need.

However, Germany’s defensive capabilities were forced to improve as Allied raids on towns and cities increased in size and frequency. Fighter aircraft were included as part of anti-aircraft defences and flak units mastered the art of keeping attacking Allied aircraft at a specific height. This made it more difficult for them to identify their specific targets, and easier for German fighter aircraft to shoot them down before they could jettison their bomb loads.

With the Allied tactic of ‘area bombing’, Germany’s anti-aircraft capabilities became harder to maintain as demand increased. The longer the war went on, along with the increased Allied bombing raids, sometimes involving more than 1,000 bomber aircraft, so the worth and effectiveness of German air-defences dwindled.
