Kwong Chi Man, “Debating ‘Douhetism’: Competing Airpower Theories in Republican China, 1928–1945,’ War in History 28, no. 1 (2021).

This article sheds lights on the difficulty faced by the minor powers when they were trying to build an effective air force during the interwar period (1919–1939) and the Second World War, using the experience of Chinese military aviation as an example. It argues that the Chinese were heavily influenced by the ideas of decisive action and strategic bombing, as well as similar ideas that were attributed (sometimes incorrectly) to the Italian General and air proponent Giulio Douhet. Only the harsh lessons of the war gradually persuaded the Chinese to adopt a more realistic approach to using air power.

Dan Ellin, ‘A ‘Lack of Moral Fibre’ in Royal Air Force Bomber Command and Popular Culture,’ British Journal for Military History 6, no. 3 (2020).

Royal Air Force aircrew endured mental and physical stresses during bombing operations. Their chances of completing a tour of operations unscathed were around one in four, and many were aware the chances were slim. Some who refused to fly were accused of ‘lacking moral fibre’ (LMF). Although this was not a medical diagnosis it is frequently viewed through the lens of mental health and reactions to trauma and it has become a powerful and important cultural phenomenon. This article re-examines LMF in the culture of the wartime Royal Air Force, before considering how and why LMF is remembered by veterans and in popular histories since the war.

James Halstead, ‘Air Power and Allenby’s Army: Arms in Palestine 1917–1918,’ War in History, (2020).

Historians have overlooked the important role played by airpower in combined arms during the Palestine Campaign, 1917–1918. This article argues the Egyptian Expeditionary Force adopted Western Front command structures, successfully integrating airpower within their command and control systems. Tactical and strategic airpower provided intelligence which allowed Corps and Army Headquarters to control the tempo of operations, while ground attack operations disrupted Ottoman command and control arrangements. This integration made a clear contribution to the success of the Egyptian Expeditionary Force at the crucial battles of Third Gaza and Megiddo.

Christian Moldjord, Paal Frederiksen, and Larry Browning, ‘Fear and Pride Among Fighter Pilots: Combat Emotions During a Bombing Campaign,’ Armed Forces & Society, (2021), doi:10.1177/0095327X20986925.

This article analyzes the combat emotions of Royal Norwegian Air Force Fighter pilots (hereafter RNoAF) during their bombing campaign over Libya in 2011. Using grounded theory in our interviews with them, we identified 12 categories of their emotions and behaviors, with variations in pride and fear emerging as the two key themes. We show how those two emotions thread through the literature of emotions in combat, and show further how our data, and the resulting matrix from an analysis of it, both apply to and extend that literature. We also show how the high and low variations of pride and fear interact to both support and counter each other. Our findings thus make an important contribution to the combat emotions literature on the action and behavior of fighter pilots.

Samuel Oyewole, ‘Struck and killed in Nigerian Air Force’s campaigns: Assessment of airstrike locations, targets and impacts in internal security operations,’ African Security Review, (2021) DOI: 10.1080/10246029.2020.1859394

The involvement of the air force in a series of Joint Task Force (JTF) arrangements, which were initiated to neutralise various security threats, accounted for a growing record of air campaigns in Nigeria. Although there is growing public attention for airpower in Nigeria, its operational relevance and associated concerns have received inadequate academic attention. Accordingly, the understanding of recent developments in Nigeria’s air campaigns to neutralise targeted threats against security across the country remains largely limited and incoherent. This study, therefore, seeks to examine trends in air campaigns, with emphasis on cases, locations, targets and impacts of airstrike, in Nigeria. For this purpose, 241 cases of airstrike with 3,210 fatalities and 273 cases of air/land operations with 2,186 fatalities that were recorded across Nigeria in the last two decades were assessed. This is expected to contribute to a growing body of knowledge on air campaigns of the Nigerian Air Force (NAF) as well as their relevance to neutralise targeted threats and associated human rights concerns in internal security operations.

Matthew Powell, ‘Debate, Discussion, and Disagreement: A Reassessment of the Development of British Tactical Air Power Doctrine, 1919–1940,’ War in History 28, no. 1 (2021).

This article investigates the work conducted by the Royal Air Force (RAF) in the development of tactical air power in the interwar period. It analyses the RAF’s theoretical doctrinal thinking during the period along with exercises conducted on a joint Service basis to further develop these ideas in practice. It will argue that, rather than neglecting tactical air power during this period as is the accepted view, much good theoretical work was done that formed a theoretical and intellectual basis for the further development of tactical air power in the light of operational experience during the Second World War.

Frank Blazich, “An Honorable Place in American Air Power” Civil Air Patrol Coastal Patrol Operations, 1942–1943 (Maxwell, AL: Air University Press, 2020).

Author Frank Blazich has spent years researching and compiling disparate records of Civil Air Patrol’s short-lived–but influential–coastal patrol operations of World War II, which he synthesizes into the first scholarly monograph that cements the legacy of this unique and vital wartime civil-military cooperative effort.

Benjamin Lambeth, Airpower in the War against ISIS (Annapolis, MD: Naval Institute Press, 2020).

Airpower in the War against ISIS chronicles the planning and conduct of Operation Inherent Resolve by U.S. Central Command (CENTCOM) from August 2014 to mid-2018, with a principal focus on the contributions of U.S. Air Forces Central Command (AFCENT). Benjamin S. Lambeth contends that the war’s costly and excessive duration resulted from CENTCOM’s inaccurate assessment of the Islamic State in Iraq and Syria (ISIS), determining it was simply a resurrected Iraqi insurgency rather than recognizing it as the emerging proto-state that it actually was. This erroneous decision, Lambeth argues, saw the application of an inappropriate counterinsurgency strategy and use of rules of engagement that imposed needless restrictions on the most effective use of the precision air assets at CENTCOM’s disposal. The author, through expert analysis of recent history, forcefully argues that CENTCOM erred badly by not using its ample air assets at the outset not merely for supporting Iraq’s initially noncombat-ready ground troops but also in an independent and uncompromising strategic interdiction campaign against ISIS’s most vital center-of-gravity targets in Syria from the effort’s first moments onward.

Richard Mead, Dambuster-in-chief: The Life of Air Chief Marshal Sir Ralph Cochrane (Barnsley: Pen and Sword, 2020).

Ralph Cochrane was born in 1895 into a distinguished naval family. After joining the Royal Navy, he volunteered in 1915 to serve with the RNAS in airships and was an early winner of the Air Force Cross. In 1918 he transferred to the fledgling RAF and learnt to fly, serving in Iraq as a flight commander under ‘Bomber’ Harris. His inter-war career saw him as a squadron commander in Aden before he became the first Chief of Air Staff of the Royal New Zealand Air Force. During the Second World War he served mainly in Bomber Command and commanded 5 Group from early 1943. He formed 617 Squadron and was instrumental in planning the legendary Dambuster Raid, the most spectacular of the War, as well as the sinking of the battleship Tirpitz. An inspirational leader, he trained 5 Group in low level target marking skills. Post war Cochrane held a string of senior appointments commanding Transport Command, Flying Training Command and finally as Vice Chief of Air Staff, retiring in 1952. He died in 1977.

Steven Paget (ed.), Allies in Air Power: A History of Multinational Air Operations (Lexington, KT: The University Press of Kentucky, 2020).

In the past century, multinational military operations have become the norm; but while contributions from different nations provide many benefits — from expanded capability to political credibility — they also present a number of challenges. Issues such as command and control, communications, equipment standardization, intelligence, logistics, planning, tactics, and training all require consideration. Cultural factors present challenges as well, particularly when language barriers are involved.

In Allies in Air Power, experts from around the world survey these operations from the birth of aviation to the present day. Chapters cover conflicts including World War I, multiple theaters of World War II, the Korean War, the Vietnam War, the Gulf War, Kosovo, the Iraq War, and various United Nations peacekeeping missions. Contributors also analyze the role of organizations such as the UN, NATO, and so-called “coalitions of the willing” in laying the groundwork for multinational air operations.

While multinational military action has become commonplace, there have been few detailed studies of air power cooperation over a prolonged period or across multiple conflicts. The case studies in this volume not only assess the effectiveness of multinational operations over time, but also provide vital insights into how they may be improved in the future.

Randall Wakelam, David Varey, and Emanuele Sica (eds.), Educating Air Forces: Global Perspectives on Airpower Learning (Lexington, KT: The University Press of Kentucky, 2020).

Compared to armies and navies, which have existed as professional fighting services for centuries, the technology that makes air forces possible is much newer. As a result, these services have had to quickly develop methods of preparing aviators to operate in conditions ranging from peace or routine security to full-scale war. The first book to address the history and scope of air power professionalization through learning programs, Educating Air Forces offers valuable new insight into strategy and tactics worldwide.

Here, a group of international experts examine the philosophies, policies, and practices of air service educational efforts in the United States, France, Italy, Germany, Australia, Canada, and the UK. The contributors discuss the founding, successes, and failures of European air force learning programs between the Great War and World War II and explore how the tense Cold War political climate influenced the creation, curriculum, and results of various programs. They also consider how educational programs are adapting to soldiers’ needs and the demands of modern warfare.

Featuring contributions from eminent scholars in the field, this volume surveys the learning approaches globally employed by air forces in the past century and evaluates their effectiveness. Educating Air Forces reveals how experiential learning and formal education are not only inextricably intertwined, but also necessary to cope with advances in modern warfare.

Darrel Whitcomb, Moral Imperative: 1972, Combat Rescue, and the End of America’s War in Vietnam (Lawrence, KS: University Press of Kansas, 2021).

In 1972, America was completing its withdrawal from the long and divisive war in Vietnam. Air power covered the departure of ground forces, and search and rescue teams from all services and Air America covered the airmen and soldiers still in the fight. Day and night these military and civilian aircrews stood alert to respond to “Mayday” calls. The rescue forces were the answer to every mans prayer, and those forces brought home airmen, sailors, marines, and soldiers downed or trapped across the breadth and depth of the entire Southeast Asia theater. Moral Imperative relies on a trove of declassified documents and unit histories to tell their tales.

Focusing on 1972, Darrel Whitcomb combines stories of soldiers cut off from their units, advisors trapped with allied forces, and airmen downed deep in enemy territory, with the narratives of the US Air Force, Army, Navy, Marines, contract pilots, and special operations teams ready to conduct rescues in Laos, Cambodia, North Vietnam, and South Vietnam. All of these missions occur against the backdrop of our withdrawal from the war and our diplomatic efforts to achieve a lasting peace. In detail, Whitcomb shows how American rescue forces supported the military response to the North Vietnamese’s massive three-pronged invasion of South Vietnam, America’s subsequent interdiction operations against North Vietnam, and ultimately the strategic bombing of Linebacker II.

A Forgotten Revolution? RAF Army Co-operation Command and Artillery Co-operation

A Forgotten Revolution? RAF Army Co-operation Command and Artillery Co-operation

By Dr Matthew Powell[1]

Jonathan Bailey wrote that the First World War was the time of a true revolution in military affairs about the development of artillery firing.[2] One of the first significant developments that took place was the creation and refinement of the ‘clock code’ system.[3] Using this system, a pilot of the Royal Flying Corps, the forerunner to the Royal Air Force (RAF), was able to correct the fall of shot of the artillery by passing to the artillery battery commander details of how far from the target the guns were. The pilot would correct the shooting of the artillery by pointing out how far away and in what direction the shells of the guns had landed. The distance would be passed on using numbers and the direction using the picture of a clock face. The target was placed in the middle of the clock face and shells that fell beyond the target and on a straight line to the target would be corrected with a call of twelve, if it fell short on the same line the call would be six, at ninety degrees left of the target nine and ninety degrees right three. Any other direction would be corrected by using the hour on the clock with which it corresponded. This system would prove to function perfectly well throughout the whole of the First World War and was the system with which the RAF went to war in 1939.

The system of correcting artillery fire remained unchanged until 1938. The Air Council were against making alterations to the clock code system as they felt that it was adequate to meet the needs that the army would face in future conflicts. They felt that light aircraft could not be kept in action close to artillery units, as had been the case in the First World War.[4] The Air Council were also fearful of introducing a new, untried, and unfamiliar system with the growing tensions in Europe at this time. The War Office was unimpressed with the Air Councils attitude and pushed for more to be done. The Air Ministry agreed to trials between the Air Officer Commanding No. 22 (Army Co-operation) Group and the Commandant of the School of Artillery in December 1938.[5] The results of these trials and further trials conducted to test aircraft as well as procedure. The results were that light aircraft over the battlefield could observe fire with the ‘clock code’ system.[6] Spitfires conducted mock attacks on the aircraft and the Taylorcraft light aircraft observing the artillery fire had a good chance of dodging the fire of a modern fighter.[7] There was, however, no training for pilots in registering targets for the artillery. If an artillery officer required an appraisal of a prospective target, the request would have to be sent along the command chain via an air liaison officer. When the artillery battery received the information, it was usually out of date.[8] There was also pressure from within the War Office to establish a Flying Observation Post (Flying OP) and to begin plans to train Gunner Officers to fly. A Flying OP was to work in conjunction with Ground Observation Post (Ground OP) in establishing targets to be engaged and operating deep behind their lines to be afforded the protection of friendly anti-aircraft guns.

The first of these Flying OPs was established in February 1940.[9] This force was established to:

[d]etermine in the light of practical experience obtained under war conditions the possibilities and limitations of the Flying OP, the most suitable type of aircraft and the most suitable organization [sic].[10]

The tests were to be conducted in three parts. The first was an initial training period. The second a practical training with the French, and a final test in the French Army area in conditions of actual warfare including shoots against German targets it was at this time that the term Air Observation Post (Air OP) was adopted.[11] The flight was sent to France on 19 April 1940.[12] The first of the three tests were conducted after the flight had moved to the continent. The final of the three tests was due to be carried out in early May, and the forces were established ready to conduct the tests on 9 May 1940.[13] The following day the Germans began to implement Fall Gelb (Case Yellow): the invasion of France and the Low Countries.[14] The artillery designated for the tests were forced to move back to their formations leaving the Air OP Flight (D Flight) waiting for the campaign to stabilise when it was clear that this would not happen D Flight was recalled to England.[15]

One of the first official moves at changing artillery co-operation policy was a letter regarding the subject sent from the Director of Military Co-operation Air Commodore Victor Goddard to Barratt at Army Co-operation Command. In this letter, Goddard states that the Air Staff were against the formation of:

[s]pecial air units for artillery observation or reconnaissance, unless it can be clearly shown that there is an urgent requirement for such units which cannot be met by Army Co-operations squadrons.[16]

The School of Artillery recommended that a certain number of aircraft should specialise in artillery work and should be trained by the School of Artillery so that they had the same tactical knowledge and the same the understanding of gunnery as an artillery officer.[17] This was just one aspect of an idea by the School of Artillery to allow aircraft to have tactical control over the fire of artillery batteries. To facilitate this, the school further recommended that a multi-seater aircraft should be employed in this work to allow an artillery officer to conduct the shoot according to artillery methods without the need for the artillery officer learning to fly. Artillery officers were also to be seconded to army co-operation squadrons specifically for artillery work.[18] The co-operation between the School of Artillery and Army Co-operation Command is evident and is surprising given the general relations that existed between the army and RAF in the wake of the Battle of France and the fall out that it had caused between the two services.[19]

Barratt, in a letter to the Under-Secretary of State for Air, wrote that:

I consider that in order to get a true and undistorted picture of this problem, it is first desirable to set out the problem as the Army [sic] sees it, and to show in this picture what they conceive to be their requirements.[20]

Again the desire to see the problem from a view that would almost certainly be contradictory to the RAF shows that Barratt and his command were willing to adopt a different approach and attitude in co-operating with at least one part of the army. Barratt also voiced his concerns regarding the ability of the Air OP to operate in the face of enemy action. It was felt that ‘the Air OP must be entirely vulnerable to any enemy fighters which cares to shoot it down’.[21] Barratt’s concern over the safety of his pilots who may be conducting shoots using the Air OP system was to be a recurring issue in the development of artillery reconnaissance.

Barratt’s response to the trials was one of scepticism, and he considered ‘that body of experience gained in the late war and since has all pointed to the advantages of the ‘Clock Code’ system’.[22] Barratt’s belief in the ‘clock code’ system stemmed more from the fear of false conclusions being drawn from brief experiments than from any sense of conservatism about changing the system used for artillery reconnaissance.[23] This became a realisation when Barratt was forced to explain to the Under Secretary of State for Air about the lack of efficiency regarding artillery co-operation in Army Co-operation Squadrons. Barratt wrote that:

I feel that much of the falling off in efficiency in this part of the Army Co-operation Squadron task has been due to the propagation of rumour as to other and better methods than those shown in AP 1176.[24]

Further trials were conducted using the artillery method during April 1941, and the conclusions reached were similar to those seen previously. These were that the artillery methods of ranging by corrections to line and range are simpler, quicker, and more efficient than any method based on the ‘clock code’.

The failures of the ‘clock code’ system in France combined with further problems faced in the fighting in Libya led to a loss of confidence in the system in the army.[25] Barratt responded that the ‘clock code’ system was not at fault in these operations but that the aircraft employed in it were operating in the face of intense enemy opposition. He was concerned that the trials had been too few and were skewed in favour of a positive result by the School of Artillery.[26] While these concerns may be interpreted as merely blocking a new development that had been shown to work to preserve the autonomy of the RAF while conducting army co-operation work. The evidence of co-operation between Army Co-operation Command and the School of Artillery, shown above, leads more to the conclusion that Barratt felt that the procedure could not be successfully carried out, and wished to see more trials conducted before it would receive his approval.

The procedure for artillery reconnaissance first developed during the First World War was only suitable for the conditions of that war. The lack of fluidity and almost stable front lines allowed a system to develop, quickly, this system, however, was only suited to those conditions. This was very quickly discovered during the first major test of this procedure against the quicker and more mobile warfare of the German Wehrmacht in 1940. The attitudes of both the British Army and the RAF to co-operation during the inter-war period, in Britain at least, did little to improve the situation before the British Expeditionary Force was stationed in France. This left those charged with the responsibility of modifying the existing procedure with only the experience of the First World War to guide them and on which to base their expectations. Much co-operation between the School of Artillery and Nos. 70 and 71 Groups of Army Co-operation Command occurred, despite the general feeling of animosity still felt by both services in Britain.[27] This co-operation was the most that had been seen between the army and RAF since the formation of the RAF as an independent force in 1918. Barratt’s move to block the adoption of the new procedure that was being trialled during 1941 can be interpreted in several ways. His reasoning for doing so, however, appears to be that of confirming the results already achieved through more rigorous and testing trials to confirm the results. Through further testing at a higher level the procedure, as well as those responsible for carrying it out, would be exposed to more stress and so a greater degree of authenticity could be achieved. Trials of this nature would also confirm if the procedure could be implemented with ease by the majority of pilots whose responsibility would be increased from observing the fall of shot to conducting shoots, potentially in the face of enemy opposition. Barratt’s major concern with the new system appears to be its increased complexity, and he was rightly concerned after his experiences in France that pilots would be unable to conduct the shoot if they had to keep a lookout for enemy fighter activity continually.
