#AirWarVietnam #BookReview – Sherman Lead: Flying the F-4D Phantom II in Vietnam

Reviewed by Dr Brian Laslie

Gaillard R. Peck, Jr, Sherman Lead: Flying the F-4D Phantom II in Vietnam. Oxford: Osprey Publishing, 2019. Appendices. Glossary. Illustrations. Plates. Hbk, 304 pp.

In the 1990s there was a plethora of published material on D-Day and the Second World War writ large. For example, Stephen Ambrose’s Band of Brothers was published in 1992. The service members who served during that conflict were in their 70s and sought to tell their stories. Comparatively speaking, the veterans of the Vietnam War were in their 40s at the time; however, time marches on. In 2019, we are where we were in the 1990s, but this time it is the veterans of the Vietnam War who are now in the 70s, and a fresh new wave of scholarship and memoirs are being published on that most confusing of conflicts.

Into the mix comes, Gaillard R. Peck, Jr.’s Sherman Lead: Flying the F-4D Phantom II in Vietnam. Peck admitted early on that his mission here is not to rehash politics or make sweeping judgments, ‘It is not my intent to go into details as to how the war was fought. Nor will I delve into policy.’ This book is simply, and excellently presented. It provides one pilot’s perspective, through his own window on the world about his time flying during the Vietnam War. Peck’s work joins other recent accounts including David R. Honodel’s The Phantom Vietnam War (2018) and Terry L. Thorsen’s Phantom in the Sky (2019), as well as Dan Pederson’s TOP GUN: An American Story (2019).

Readers might recognise Peck’s name as he was also one of the commanders of the famed MiG-flying Red Eagles squadron and author of America’s Secret MiG Squadron: The Red Eagles of Project CONSTANT PEG (2012) that was also published by Osprey. Peck now turns his attention to his time as a young pilot flying and fighting in the F-4 Phantom II in 1968-1969. ‘Evil’ as he has been known to generations of fighter-pilots at Nellis Air Force Base has decided to add prolific writer to an already fantastic resume. Peck is something of a legend in the US Air Force’s Fighter community, as he has been a staple at the F-15 and F-22 Weapon’s School for decades.

Sherman Lead is ostensibly about flying the F-4 in combat, but this work is much richer than just that. Peck included the social side of life for American aircrews flying out of Thailand, something missing in other works. Peck also deftly included aspects of flying left out of so many books. This included the process and importance of mid-air refuelling, a nice tip of the hat to the tanker community.

The book generally follows his training progression, from learning to not only flying fighters but also how to employ them. Peck also deftly demonstrated how the training at an air-to-ground gunnery range was accomplished as well as the physics and geometry of putting bombs on a target. By using both the training environment as well as his experiences employing munitions in North Vietnam, Laos, and Cambodia, the reader gets the sense that there is a genuine difference between precision-guided munitions and the precision-employment of munitions. Peck adroitly described all of these without being overly technical; thus the book can be enjoyed by the professional and the enthusiast alike.

Of course, the real effort of the book is to be found in his operations flying out of Ubon Royal Thai Air Base, Thailand and his missions over North Vietnam as part of Operation ROLLING THUNDER or over Laos as part of Operation STEEL TIGER. Perhaps the most significant contribution Peck has made to our understanding of the Vietnam War is that this is a dual ‘biography’ in that it is a memoir of himself, but it is also the biography of the F-4 Phantom II. This book is as much about how the war changed man as it is about how the war changed the machine.

Sherman Lead is destined to join the other classic memoirs on air power in Vietnam, including Jack Broughton’s Thud Ridge (1969) and Rick Newman and Don Shepperd’s Bury Us Upside Down (2006). Historians of air power and the history of the US Air Force will especially enjoy this book, but it will also find a wider audience in those seeking to understand individual and unique perspectives on America’s participation in the war in Vietnam.

#AirWarVietnam – Weaponised Helicopters and Counterinsurgency: An Exploration of the Different Approaches Advocated in Vietnam by the US Army and the US Marine Corps

Editorial Note: During 2019, From Balloons to Drones is running a series of articles looking at various aspects of the air war over Vietnam from the French-Indochina War through to the end of the Vietnam War. In this article, Dr Robert Kodosky discusses the differing attitudes towards armed helicopters between the US Army and US Marine Corps as they entered the Vietnam War. If you would like to contribute to the series, then please email our editor, Dr Ross Mahoney, at airpowerstudies@gmail.com or via our contact page here. The official call for papers is here.

In Vietnam, the US Army utilised helicopters according to its thinking about conventional warfare during the previous decade. Without the ‘helicopter in Vietnam,’ US Army officials concluded that America and its allies in Vietnam ‘would not have been able to outmanoeuvre the enemy nor exercise their superior firepower.’[1] While accurate, this observation adhered to the assumption that these tactics aligned to an effective counterinsurgency strategy. As one wartime study commissioned by the Department of Defense contended, ‘the crude use of overwhelming firepower seems more appropriate to total war.’[2]

The US Army appropriated helicopters to fight the war it wanted in Vietnam, one of attrition. In comparison, Marines employed rotary craft to fight the war they got. The US Marine Corps (USMC) weaponised helicopters to align with counterinsurgency goals and remained cautious about the firepower they delivered. In July 1967, for example, the commander of Fleet Marine Forces, Pacific, General Charles Krulak noted that armed helicopters carried out two-thirds of all USMC UH-1E flights in Vietnam during the previous year. He found this unacceptable. More arms, Krulak observed, denied the USMC ‘the eyes which are so urgently needed over the jungle environment.’ He suggested that the USMC had erred in putting ‘too many rocket pods’ on UH-1Es and had ‘unconsciously encouraged their misuse.’[3]

This example, set by the USMC in Vietnam, remains vital today. Despite ‘deliberate application of COIN [counterinsurgency] practices in Iraq and Afghanistan,’ some aviators have remained ‘focused on killing insurgents.’ One AH-64 Apache battalion commander deployed to Iraq cited ‘winning hearts and minds’ as ‘ground-guy stuff.’[4]

As such, this article explores foundational thinking surrounding the decision to weaponise helicopters in both the US Army and the USMC. Each initially conceptualised weaponising helicopters to wage a conventional war, whether as weapons platforms to combat tanks or to facilitate amphibious landings. This resulted in experimentation in ways to arm helicopters to deliver indiscriminate firepower. While the US Army remained on this path, the USMC deviated from it, based on their observations of the French effort to quell insurgents in Algeria and their own early experience in Vietnam. The USMC then decided to weaponise helicopters in Vietnam because they perceived them better able to deliver discriminate firepower than fixed-wing craft.

Blitzkrieg from Above

Contemporary observers largely concurred that the Vietnam War provided the ‘crucible for the helicopter.’[5] Military officials reaffirmed this view afterwards, citing helicopters as counterinsurgency tools essential for ‘mobility, rapid deployment of troops and logistics support.’[6] The US Army declared that helicopters ‘represented the most revolutionary change in warfare since the blitzkrieg.’[7]

This view found widespread acceptance. According to US Army General William C. Westmoreland, commander of Military Assistance Command, Vietnam between 1964 and 1968, America ‘achieved the ability to use the helicopter and employ the tactics of air mobility.’ This reflected the US Army’s view that its efforts during the Korean War suffered from doctrinal and technological limitations that prohibited employing rotorcraft to gain the initiative by enabling mobility. In Korea, this resulted in a deadlock. Westmoreland observed that the Vietnam War readied America’s use of helicopters to ‘take off.’ This ‘is not the end,’ he advised, it ‘is only the beginning.’[8]

This proved prescient. In 2004, the US Army alone deployed more than 500 helicopters to Afghanistan and Iraq. In counterinsurgency missions especially, the helicopter played ‘a key role.’ It continues to do so. There exists an ‘intensive use of rotary wing aircraft,’ rendering the helicopter as ‘omnipresent across a large spectrum of defense missions.’[9]

There exists good cause, however, to explore the centrality of helicopters critically in the execution of counterinsurgency operations. A recent study concerned with American involvement in Vietnam, Soviet engagement in Afghanistan and French participation in Algeria argues that helicopters proved ‘indecisive or bad at enabling legitimacy, population control, and isolation, key tenets of successful COIN.’[10]

This view is reflected by commentary offered by a counterinsurgency veteran to the Armed Forces Journal. It cited the proclivity of AH-64 Apache and OH-58D operators for flying low to the ground. While this proved ‘occasionally fruitful in detecting enemy activity,’ it observed that helicopters ‘can only scatter a farmer’s sheep so many times before he sees coalition forces as an annoyance rather than an ally.’[11]

Such criticism is not new. Sir Robert Thompson, who directed the British Advisory Mission to the Republic of Vietnam between 1961-1965, became an outspoken critic of America’s strategy in Vietnam. Thompson was a widely respected expert on counterinsurgency based on his experience in Malaya. Thompson labelled attrition, using the number of Vietnamese communists killed as a metric of success, as an ‘error.’ The ‘main contributing factor to this,’ he contended, ‘was the helicopter.’[12]

The Army Way – Cavalry Without Horses

The development of the US Army’s thinking about the use of helicopters as air cavalry capable of aerial assault originated during the Korean War. In July 1952, the US Army’s 6th Transportation Company (Helicopter) received the H-19 Chickasaw. Capable of faster and farther travel than the H-13, the Chickasaw constituted the US Army’s first true cargo and transport helicopter. While used to assist medical evacuation and resupply efforts, the H-19 executed the US Army’s first air assault combat missions, shaping Army thinking about helicopters after the war.

In 1955, Redstone Rocket likened helicopter performance favourably in Korea to fixed-wing operations during the Second World War. It framed the helicopter’s potential within conventional missions such as ‘smoke laying’ and ‘armor column control.’ It observed that helicopters took with them ‘two American military traditions: To get there ‘fustest with the mostest’ and to ‘hit ‘em where they ain’t.’”[13]

James M. Gavin, a veteran of the Second World War and later a Lieutenant-General in the US Army of the 1950s, introduced his concept of airborne armoured cavalry in ‘The Future of Armor,’ an article that appeared in the US Army’s Infantry Journal in 1948. He argued that ‘striking at high speed by air’ and ‘entering ground combat’ enabled ‘mobility and the retention of the initiative.’ Armoured cavalry offered this potential, Gavin contended, rendering it uniquely able to ‘play the decisive role in future airborne combat.’[14]

Gavin expanded on his idea over the next 15 years, including in an article for Harper’s Magazine, published in 1954. In ‘Cavalry, and I Don’t Mean Horses,’ Gavin suggested that the US 8th Army in Korea suffered from a lack of airmobile cavalry. He pressed for the return of a ‘mobility differential,’ one that could make a difference for American commanders in Korean-style conflicts and any war waged directly against the Soviet Union.

Mobility comprised more than speed, Gavin clarified, it included the capability to deliver superior firepower.[15] The Second World War informed Gavin’s thinking and influenced the US Army’s development of its air assault concept. During the Second World War, in addition to its functions of target acquisition and artillery fire observation, organic US Army aviation ‘provided highly responsive capabilities.’[16]

Gavin served in President Dwight Eisenhower’s administration as Assistant Chief of Staff for Operations (G-3) and was a critic of the President’s ‘New Look’ national security policy that prioritised massive nuclear retaliation. Gavin advocated the need for force readiness, ‘based on his concepts of mobility, firepower and control derived from his experience in World War II.’ He cited helicopters as able to ‘provide the mobility advantage that U.S. forces needed.’ These fulfilled the traditional cavalry missions of ‘reconnaissance, screening and exploitation.’[17]

Gavin’s notions about air mobility became those of the US Army. General Hamilton Howze, appointed by Gavin as the first Director of Army Aviation in 1955, instituted them. In this capacity, Howze ‘saw to it that every imaginable weapon was strapped onto a US-1 (Huey).’[18] Also a veteran of the Second World War, Howze envisioned the utility of air mobility within conventional thinking about linear warfare against a mechanised adversary.

By the winter of 1961, with ‘the Army’s aviation resources suddenly in high demand’ due to America’s increasing commitment in Vietnam, Secretary of Defense for the President John F. Kennedy’s administration, Robert S. McNamara, grew ‘sharply critical of the Army’s conservative approach’ to improve air mobility.

Kennedy had shifted national defence from the massive retaliation endorsed by Eisenhower’s New Look. He called for ‘Flexible Response.’ This aimed to counter Soviet aggression using proxies throughout the world. It emphasised a rebuilt conventional force with the capacity to deploy quickly. McNamara pressed the military for ‘maximum mobility.’ He tasked the US Army with figuring out how to achieve this, within ‘an atmosphere divorced from traditional viewpoints and past policies.’[19] Howze, McNamara suggested, stood capable of creating such a climate.

The Howze Board

The US Army’s Tactical Mobility Requirements Board convened under Howze’s direction in May 1962. Its membership included 200 officers and 41 enlisted personnel from the Army, along with 53 civilians. The US Air Force (USAF) observed the Board’s work, carried out from May until the end of July. Testing utilised 125 helicopters and 25 fixed-wing aircraft to log over 11,000 hours of flight time. Conditions simulated a variety of scenarios, from Lieutenant-General Walton Walker’s withdrawal to Pusan in 1950 to counter-guerrilla exercises.

It all constituted ‘tactical experimentation’ with considerable attention provided to wargaming against the Soviet Union and an emphasis on the potential to deliver ‘heavy firepower.’ One ‘suggestive scenario’ featured in the Board’s final report, for example, simulated a Soviet incursion in Iran through the Zagros mountains.[20]

Howze briefed the Pentagon in 1957 about the potential of air mobility to defend against a Soviet attack. Only the terrain shifted between then and 1962 as the earlier simulation situated the campaign in Bavaria. The interest in maximising the firepower of helicopters remained unabated.

As Director of Army Aviation, Howze worked ‘to prove that the helicopter’ constituted a ‘superior weapons platform.’[21] In 1958 the US Army successfully tested an H-34 loaded with 40 2.75- and 2.5-inch rockets, nine machine guns and two 20mm cannon.[22]

For McNamara, the Howze Board staged a full field demonstration which featured four gunship helicopters attacking fortifications with machine guns and 2.75-inch rockets. It all climaxed with 30 Hueys ‘flying low, from behind the grandstands, at 110 miles per hour.’ Loaded with infantry, the helicopters landed in the smoke where soldiers dismounted and attacked. It all took two minutes.[23]

The Howze Board sought out information about Southeast Asia by dispatching a team to visit Military Advisory Assistance Groups in Vietnam, Laos, Thailand, Cambodia, and Marine Task Force 116 Headquarters at Udorn, Thailand. Since the middle of 1962, a UH-1 Tactical Transport Helicopter Company armed with machine guns and 2.75-inch rockets operated in Vietnam to escort CH-21 helicopters. Nevertheless, the visiting Board members reported back that there existed resistance to arming helicopters from the USAF.

This only intensified with the Board’s recommendation for US Army air mobility, to include weaponised helicopters. A USAF Board headed by Lieutenant-General Gabriel Disosway issued a four-volume rebuttal to the Howze findings. It criticised weaponising helicopters, utilising an OV-1 Mohawk as a close-support aircraft and argued that USAF fighter-bombers provided better support.

This resulted in the decision to further test the airmobile concept by activating the 11th Air Assault Division (Test) at Fort Benning in 1963. Eighteen months of tests and exercises brought approval from all members of the Joint Chiefs of Staff except USAF General John McConnell who maintained his services’ opposition. For the USAF, the fundamental issue remained ‘centralised versus decentralised aircraft management and command.[24]

Ultimately, the USAF won the battle, but it lost the war. The US Army relinquished the 24-armed Mohawks recommended by Howze. It activated the 1st Cavalry Division, however, in July 1965. By the 3 October 1965, the entire division reached its base area at An Khe in Vietnam’s Central Highlands. Its orders to seek out and destroy a North Vietnamese force building up in the area culminated in the Battle of Ia Drang in November.

The US Marine Corps Mantra – Tolerance, Sympathy and Kindness,

The USMC had long expressed interest in the idea of weaponising helicopters. As far back as 1949 they ‘envisioned that the supporting tactics’ of helicopters ‘might include the use of covering artillery fire’ to ‘neutralize anti-aircraft weapons’ and tanks.[25] The limited lift capability and the instability of helicopters at the time rendered it unworkable. The idea remained, however, and the war in Vietnam reinvigorated it.

Lieutenant Colonel Victor J. Croizat served as the first USMC advisor to the Army of the Republic of Vietnam (ARVN). An authority on French military matters, Croizat visited Algeria where the French faced an insurgency. Accompanied by Major David Riley, Croizat reported their observations to Washington in July 1957.

The French employed helicopters judiciously, in support of ground elements, only until these became ‘capable of self-support with organic weapons.’ While obsolete helicopters ‘hampered’ French efforts, Croizat recommended that the USMC remain ‘abreast of the French experiences.’ As the USMC did that, the Division of Aviation cited that ‘the basic problem [still remaining] is that of determining whether or not Marine Corps Helicopters should be armed.’[26]

There existed a few reasons for opposing armed helicopters in the USMC. These included the inadequacy of rotary-wing aircraft to serve as weapons platforms and the perceived inferiority of helicopter pilots. The most substantial objection, however, stemmed from fears of helicopters replacing fixed-wing to protect helicopter transports.

This necessitated a ‘major change of concept’ while threatening the identity of the USMC. According to Major General Norman J. Anderson, planners foresaw that ‘sacrificing fixed wing capabilities to helicopters’ risked the USMC losing its primary distinction from the US Army; ‘its combination of ground and air combat power.’[27]

By April 1962, a USMC medium helicopter squadron had deployed to Vietnam. Marine Medium Helicopter Squadron 362 (HMM-362) constituted the second element of task unit SHUFLY which occupied an old Japanese landing strip near Soc Trang, 85 miles south of Saigon. It operated in support of ARVN forces throughout southern Vietnam.

Unlike US Army helicopters already operating in other parts of South Vietnam, the USMC HUS-ls remained unarmed. USMC commanders reasoned that weapons mounted in the cargo hatch mitigated against efficient loading and unloading in landing zones. Moreover, armed aircraft presented hostile appearance to Vietnamese civilians. They acknowledged this as counterproductive to counterinsurgency by providing fodder for insurgent propaganda.[28]

The USMC began devising counterinsurgency-specific roles for helicopters. For example, they soon observed that during large engagements, small numbers of insurgents peeled away to escape into covered areas. The USMC instituted ‘Eagle Flights’ aimed to thwart such escapes in which four helicopters loaded with ARVN troops circled over contested areas and timed landing to cut off any attempted escapes.

The USMC quickly deduced the ‘unique links’ between the ‘political and military aspects of the struggle in Vietnam.’[29] By August 1962, the US marines at Soc Trang began arming their helicopters by mounting M-60 machine guns inside the cargo hatch. While this constituted a radical change, one that realised fears of surrendering fixed-wing capabilities to rotary craft, the USMC adopted it as a defensive tactic, one compliant with the counterinsurgency they sought to execute. The M-60s served as protection for landing and only fired at clearly identified enemies. The USMC refrained from their use in the Mekong Delta’s heavily populated areas.[30]

The US marines who served at Soc Trang became the most vocal advocates of weaponising helicopters. Their argument, however, derived from their conviction, gained from experience. That argument was that counterinsurgency success hinged on a discriminate application of firepower. The early operational experience gained by the US marines that served at Soc Tran convinced them that helicopters could operate with restraint better than fixed-wing aircraft. They sought to explain that in the densely populated areas where helicopter assaults transpired, the application of firepower required ‘almost surgical precision.’

While 500-pound bombs delivered by fixed-wing aircraft ‘might indeed suppress fire,’ this would ‘hardly win the ‘hearts and minds’ of the frightened or uncommitted residents.’[31] According to Colonel Noah C. New, the USMC ‘learned early’ the incompatibility of helicopters and jets in Vietnam. Because there ‘were so few Marines involved, at Soc Trang’ however, making a ‘convincing argument’ to others that the war in Southeast Asia required ‘new approaches’ proved difficult.[32]

General Wallace M. Greene, Commandant of the USMC between 1964 and 1967, grasped the problem. In May 1965, six-armed Marine UH-1Es arrived at Da Nang. Greene explained this to the press, attributing the development to the ‘peculiar circumstances’ that the USMC confronted. He rationalised it as a counterinsurgency imperative, noting that ‘tactical fixed wing aircraft have not been available because of political considerations.’ The armed helicopter, Greene insisted, represented an appropriate tool for the USMC ‘in the environment of political-military artificialities which exist in the Republic of Vietnam.’[33]

The decision by the USMC to weaponise helicopters exhibited recognition of the Vietnam War’s nature. It derived from the early experience at Soc Trang but also profited from the USMC’s experience in waging America’s ‘small wars’ in the early twentieth century.[34] This is evident through the efforts initiated by USMC General Lew Walt. He commanded Marine Amphibious Force III that operated in I Corps, the tactical zone that included South Vietnam’s five northernmost provinces.

Walt, a veteran of both the Second World War and the Korean War, identified the conflict in Vietnam as something different. It resembled the kinds of engagements he heard about as a young officer ‘from men who fought Sandino in Nicaragua or Charlemagne in Haiti.’ Walt understood the USMC mission in Vietnam as framed by ‘sympathy, understanding, regard for the people.’[35] This echoed advice from the Small Wars Manual of 1940 that noted that ‘tolerance, sympathy and kindness should be the keynote of our relationship with the mass of the population.’[36] That insight informed the decision made by the Marines to weaponise helicopters in Vietnam.

Conclusion

In contrast to the US Army, the USMC sought to apply firepower discriminately. They also recognised the value of helicopters to provide reconnaissance, a critical task of counterinsurgency as ‘the enemy relies on stealth instead of mass.’[37] According to Major General William Gayler, commander of the US Army’s Aviation Center of Excellence, ‘the most critical gap for the Army is a light armed reconnaissance helicopter.’ One with the ability ‘to fight for information about terrain and enemy, that enables ground force commanders, that gives decision space, manoeuvre room and reaction time.’[38] Superior eyesight is sometimes more important than superior firepower. In Vietnam, the USMC understood this well. As military officials contemplate the use of helicopters in contemporary counterinsurgencies, ones where ‘hearts and minds’ remain as vital to secure as they did in Vietnam, the history of thinking within both the USMC and the US Army about weaponising helicopters for use in Vietnam offers valuable lessons.

#Commentary – Biplanes against Battleships: The Fairey Swordfish Biplane and Lessons for Today’s Air Power

#Commentary – Biplanes against Battleships: The Fairey Swordfish Biplane and Lessons for Today’s Air Power

By Dr Adam Leong Kok Wey

The Fairey Swordfish flew just above the sea waves at about 30 feet while anti-aircraft artillery shells exploded around it, the sea waters splashing high due to the impact. The pilot, Lieutenant M.R. Maund, struggled to keep his plane steady to release his torpedo at an Italian battleship.[1] Maund flew a Swordfish biplane: one of the 20 Swordfish aircraft from HMS Illustrious that took part in the air attack on the Italian Navy’s (Regia Marina) battleship fleet in the harbour of Taranto on the night of 11-12 November 1940. The Italians had six battleships, 14 cruisers and 27 destroyers at Taranto.[2] During this night attack, the Swordfish aircraft dropped torpedoes and bombs and managed to sink a battleship (Conte di Cavour) while severely damaging two more (Caio Duilio and Littorio). Only two Swordfish aircraft were shot down. As a result of the attack, half of the Regia Marina’s capital ship fleet was disabled, giving the Royal Navy (RN) some tactical space and time to conduct its maritime operations in the Mediterranean.[3]

More importantly, the Battle of Taranto signalled a change in naval power and the use of air power.  It demonstrated the value of using aircraft to destroy an enemy’s fleet. The lessons of the Battle of Taranto were not lost on those who observed the effects of the operation. The Japanese Assistant Naval Attaché in Berlin visited Taranto and studied the raid. His findings then fed into the planning process for the massive surprise air raid against the US Navy at Pearl Harbor on 7 December 1941. The use of precision airstrikes against naval targets rendered the fleet-in-being strategy as a highly risky practice, and subsequent Second World War naval battles with air power serve to highlight this point.

The Swordfish aircraft, which was successfully used in the attack against Taranto, was an obsolete aircraft when the Second World War started. It was a fabric wire biplane first flown in 1934 and became operational in July 1936 with the Fleet Air Arm (FAA) of the Royal Air Force, which was later transferred to the control of the Royal Navy. It had a top speed of just 138 mph; a service ceiling of 10,890 feet; a range of 1,028 miles; and it could carry either a 1,600 lb torpedo or a 1,500 lb load of depth charges, mines or bombs.[4]  For self-defence, it was armed with a .303 Vickers machine gun above its engine and another .303 Vickers machine gun operated by the rear gunner. It had a crew of three – a pilot, a navigator-observer, and a radioman-rear gunner – flying in an open cockpit. Due to its fabric skin-cover holding the aircraft together, it was nicknamed the ‘Stringbag.’

By the time of the outbreak of the Second World War, the Swordfish was slow and vulnerable to faster and more agile monoplane fighters. Nevertheless, the FAA used it as its primary torpedo and reconnaissance aircraft on the RN’s aircraft carriers during the war. However, its slow speed and crude design allowed it to fly slow and manoeuvre at low altitude. These qualities were crucial to victory at Taranto, when the Swordfish aircraft flew low, almost at sea wave height, enabling them to avoid Italian anti-aircraft artillery. The slow speed also allowed the Swordfish aircraft to fly around some barrage balloons and unleash their ordnance with accuracy. The fabric skin construction of the Swordfish also saved it from light cannon shells armed with contact fuses as the shells shot through the soft fabric.

The anti-battleship feat of the Swordfish was repeated when they took part in the hunt for the German Navy’s (Kriegsmarine) battleship, Bismarck. Swordfish aircraft from HMS Ark Royal launched a torpedo attack against Bismarck on 26 May 1941 and managed to destroy its port-side rudder. This caused the Bismarck to turn in circles.[5] The RN’s surface fleet eventually caught up with the Bismarck and sank it the next day. Ironically, the HMS Prince of Wales, which took part in the sinking of Bismarck, was sunk by Japanese air power on 10 December 1941 off the coast of eastern Malaya.

The Swordfish continued to be manufactured (2,391 were built) and used by the FAA until the end of the Second World War.[6] Despite its obsolescence at the start of the war, it doggedly flew on and even outlived some of its more modern contemporary aircraft. The Swordfish gained a solid reputation as the most successful British naval aircraft with the highest score of Axis ships sunk during the Second World War.[7] The rugged biplane was finally retired from active service in 1946.

The tactical lessons drawn from the experience of the Swordfish in the Second World War should not be lost on modern observers. Many modern countries are looking to procure the latest technologically superior combat aircraft to equip their air forces, at very expensive prices. For example, there are continued debates today on the viability for some air forces to acquire either the F-35 Lightning II or modernised versions of the F/A-18 Super Hornet or the F-16V Viper. Perhaps it might be prudent to understand that sometimes older platforms if used smartly and asymmetrically to offset their disadvantages, can yield some strategic utility as the humble Fairey Swordfish did during the Second World War. After all, it is not the machines that count, but the tactical effects yielding strategic utility that matter.

#AirWarVietnam – Making a MiG-Killer: Technology and Signals Intelligence for Air-to-Air Combat in Vietnam

#AirWarVietnam – Making a MiG-Killer: Technology and Signals Intelligence for Air-to-Air Combat in Vietnam

By Dr Mike Hankins

Editorial Note: During 2019, From Balloons to Drones is running a series of articles looking at various aspects of the air war over Vietnam from the French-Indochina War through to the end of the Vietnam War. In this article, Dr Mike Hankins discusses the use of signals intelligence via Project Teaball that helped to improve the air-to-air combat ratios of the United States Air Force during the Vietnam War. If you would like to contribute to the series, then please email our editor, Dr Ross Mahoney, at airpowerstudies@gmail.com or via our contact page here. The official call for papers is here.

Air-to-air combat in the Vietnam War has long been a sore subject for some observers.[1] Sources vary, but U.S. forces overall killed approximately 200 MiGs while losing about 90 planes to them, for a ratio of about 2.2:1.[2] Robert Wilcox, in his history of the Top Gun program, calls this ‘embarrassingly low.’[3] Looking just at 1968, the picture is even bleaker. The US Navy was disappointed with its 3:1 ratio and the US Air Force (USAF) traded McDonnell Douglas F-4 Phantoms for MiGs at nearly a 1:1 rate. During the bombing halt between 1968 and 1972, both services sought to upgrade their technology and training, including the creation of the US Navy Fighter Weapons School, also known as ‘Top Gun.’ In 1972 when the LINEBACKER bombing campaign began, the US Navy’s air-to-air record jumped to 6:1. The USAF struggled in the early months of LINEBACKER, earning a negative kill ratio for the first time in the war and perhaps in its existence.[4]

The US Navy is often praised for their changes to training procedures (even though Top Gun initially had little support from US Navy leaders) while the USAF is often criticised for over-reliance on technological solutions.[5] However, the most significant improvement in air-to-air combat for the USAF was the result of a technological system: Project Teaball – a Ground Controlled Intercept (GCI) system that allowed analysts on the ground to track enemy planes in real-time and communicate that information to pilots in the air.

‘Teaball’ was just as critical to the USAF’s air combat success during the LINEBACKER campaigns as Top Gun was for the US Navy. It demonstrated that the USAF was open to change and adapted its technological culture to meet new challenges. This is not to take away from the undeniable success of the Top Gun program, nor to diminish the importance the USAF’s effective RED FLAG program that began shortly afterwards. In the last throes of the Vietnam War, both technology and training worked in tandem.

Web of Confusion

North Vietnamese pilots had long relied on GCI to direct their movements – ground controllers used their extensive radar coverage of the area to track aircraft and give detailed second-by-second instructions to MiG pilots.[6] American forces were different. They tended to rely more on the initiative and skill of individual pilots, but they also had far less radar coverage of the areas they flew over in North Vietnam. Complicating, this was the fact that US radar stations were not well integrated, creating a confusing web of systems competing for pilots’ attention.

The USAF operated a ground radar covering the southeast at Da Nang. Another radar further north at Dong Ha known as ‘Waterboy’ covered the lowest reaches of North Vietnam, although few air-to-air engagements occurred there. For further coverage, USAF flew a Lockheed EC-121 known as ‘College Eye,’ which was excellent over water but was less accurate over land. Other radar stations existed in Thailand, including ‘Brigham,’ at Udorn, and ‘Invert,’ at Nakon Phanom. These stations contributed ground control and navigational assistance, although their short-range provided almost no coverage of North Vietnam itself.

Hankins Radar Map
This map shows the radar coverage of systems prior to Project Teaball. Note that coverage above the 20th parallel, where air combat was much more likely, was almost nonexistent.

The US Navy used a system called ‘Red Crown,’ a ship-based radar located in the Gulf of Tonkin, to provide early warning of approaching MiGs. There was some limited cooperation between ‘Red Crown’ and ‘College Eye’ during Operation ROLLING THUNDER. The bottom line for all these radar systems was that none of them was effective for strikes further North than the 19th parallel, where air combat was more likely, and some of these systems, such as ‘Red Crown,’ could not effectively track planes below 10,000 feet, where MiGs often flew.[7]

However, radar was only one way to gain situational awareness of enemy MiGs. Communications surveillance, or signals intelligence (SIGINT), could track enemy movements and plans. In 1967, the USAF brought in new EC-121s known as ‘Rivet Top; to do just that: Intercept North Vietnamese communications and pass on vital information to American pilots. ‘Rivet Top’ was a success. In its limited time of employment, American forces claimed 20 MiG kills, 13 of which received direct contributions from ‘Rivet Top.’[8] However, the ROLLING THUNDER campaign ended before they could make a more significant contribution. At the beginning of the LINEBACKER Campaign, the US Navy’s ‘Red Crown’ ship returned, and the USAF instituted a system known as ‘Disco,’ essentially a slightly upgraded version of ‘College Eye.’ Under ‘Disco,’ multiple EC-121s provided a larger area of radar coverage and continued the SIGINT role provided by the ‘Rivet Top’ equipment, although the system suffered many of the same problems that plagued the ‘College Eye’ system, such as a limited range, limited crew and equipment capacity, and the need to stay in slow, controlled orbits.[9]

Both sides found that GCI was key to air-to-air victory. General John Vogt, Director of the Joint Staff and later commander of the Seventh Air Force, argued that MiG successes were attributable entirely to how their radar systems connected to their command and control practices.[10] USAF Ace fighter pilot Richard ‘Steve’ Ritchie went so far as to state that flying a protective escort without GCI warning of incoming MiGs was ‘useless,’ and that employment of US GCI ‘was one of the primary reasons that we were able to engage MiGs and effect kills.’[11] Yet the limited range, communications problems, and frequent technical failures limited US GCI efforts.

Green Door Syndrome

An equally serious bureaucratic problem aggravated these technological difficulties. Unknown to most fighter pilots, the National Security Agency (NSA) frequently intercepted North Vietnamese communications – including information about MiG flights. Some NSA analysts, such as Delmar Lang, had previously advocated combining these intercepts with GCI to provide a more accurate picture of enemy locations and movements. Lang had developed such a system in the Korean War, contributing to the success of North American F-86 Sabre pilots. Lang had offered to create a similar program in Vietnam, but both NSA and USAF leaders, particularly Major General George Keegan, Director of Air Force Intelligence, repeatedly turned him down.[12] Interception of North Vietnamese transmissions was classified, and American pilots did not have proper security clearance. This policy was not unfounded. Using these intercepts could undoubtedly aid American pilots but using them too frequently risked alerting the North Vietnamese that the US was intercepting their signals.[13]

This was a dilemma for American planners who needed to balance using the data with keeping its existence secret. However, USAF leaders such as Keegan simply refused to pass on any information to American pilots in combat. This created a sense of ill will between pilots and intelligence agents. As former USAF intelligence officer, Gilles Van Nederveen noted, ‘US pilots, already frustrated by the small amount of data provided to them, felt betrayed when they learned that some losses over Vietnam could have been prevented if intelligence data had been shared with them.’ This animosity grew so prevalent that it received a name: ‘green door syndrome,’ so labelled because, in many combat wing bases in the theatre, classified information was kept in vaults usually behind a green door.[14]

LINEBACKER and Project Teaball

When bombing (and air-to-air combat) resumed in earnest with the LINEBACKER campaign in May 1972, the US, particularly the USAF, received what Colonel Russ Everts, an F-4 Pilot, generously called ‘an old fashioned butt kicking, pure and simple.’[15] After some initial successes that May, in June and July, USAF F-4 Phantoms claimed 8 MiGs, with the US Navy shooting down only 3. While the US Navy only lost one F-4, USAF lost 13.[16] The US Navy could still claim their previous 3:1 ratio; the USAF had sunk to its lowest ratio during the war, 0.6:1. For the first time in the war, the kill ratios favoured the North Vietnamese.

These reversals rippled through USAF quickly, prompting investigations into the quality of fighter pilots. General William Momyer, then commander of Tactical Air Command (TAC), who had previously resisted any alterations to training procedures, changed his mind and recommended the creation of an ‘Aggressor’ squadron to simulate MiGs in air combat training (building on a program at Nellis run by Major Roger Wells). Although Chief of Staff of the Air Force General John Ryan approved the Aggressor concept at that time, the program did not begin until after the war was over and thus it had no effect on air combat in Vietnam.[17]

However, one element the USAF could fix in time to make a difference was their GCI system. The summer’s heavy losses, increasing concern from Vogt about the shortcomings of American GCI, and pressure from eager NSA analysts and USAF pilots all overrode earlier concerns with sharing classified intelligence and pushed the issue higher up the chain of command. Ryan directly contacted the head of the NSA, Admiral Noel Gayler – himself a former US Navy aviator – and requested the creation of an improved early warning system to alert pilots to approaching MiGs. With Ryan and Gayler’s approval, General Vogt worked with Delmar Lang and Lieutenant Colonel William Kirk to establish Project Teaball at Nakhom Phanom Air Force Base in Thailand in August 1972.[18]

‘Teaball’ took the classified NSA intercepts and combined them with other US radar sources. These included the radio calls sent from North Vietnamese pilots to their ground controllers and vice versa, revealing precise locations and vectors for their MiGs. This information was fed into a computer known as ‘Iron Horse’ that took data from these sources and quickly synthesised it into a composite display showing a near real-time picture of the location of all friendly and enemy aircraft over North Vietnam.[19] ‘Teaball’ operators then sent this information directly to pilots via Ultra-High Frequency (UHF) radio signals relayed through a Boeing KC-135 aircraft code-named ‘Luzon.’

There was still tension between some pilots and the intelligence community. Kirk worked to build trust between the two groups and overcome ‘green door syndrome’ by personally visiting every single wing in the theatre to brief them on ‘Teaball’s’ capabilities, the accuracy of its data, and the methods he used to contact pilots directly.[20] Finally, US pilots could have situational awareness of the aerial battlefield and early warning of MiG threats. However, ‘Teaball’s’ implementation differed from the authoritarian North Vietnamese GCI system and simply provided information to pilots. The American ground controllers often suggested courses of action, but individual pilots handled threats at their discretion.

The Best Show We’ve Had

‘Teaball’ was only active from August 1972 until the end of LINEBACKER operations in October. In that time, USAF F-4’s shot down 21 MiGs with only six losses. Of those kills, 13 were a direct result of vectoring from ‘Teaball.’[21] Of those losses, five of the six occurred when ‘Teaball’ was down due to technical failure, demonstrating just how critical the system was to the USAF effort. When examining only MiGCAP flights, USAF F-4s claimed 18 kills with five losses, a nearly 6:1 ratio.[22] During that same timespan, the US Navy got two kills but lost two Phantoms.[23] General Vogt extolled the program’s success:

This is the most effective show we’ve had during the entire war with the battle against the MiGs […] This proved one thing – if you can show the American fighter pilot where [the enemy] is in sufficient time, he’ll shoot him down.[24]

Vogt went on to say:

Same airplane, same environment, same situation, same tactics; largely [the] difference [was] Teaball. It was one of the most impressive developments we’ve had out here.[25]

Pilots praised ‘Teaball’ as well. One mission report stated: ‘A good GCI capability made the difference, and will in the future.’ Another echoed: ‘Computerized real-time intelligence will get more kills than all the fighter sweeps we can put together.’[26]

No matter how well-trained a pilot is, if they do not realise they’re under attack, they cannot use their training. ‘Teaball’ gave them that warning, preventing further losses. ‘Teaball’ also provided more accurate visual recording of encounters than the memory of pilots could provide, enabling both a better study of enemy tactics and a useful training tool. It was also invaluable for search and rescue efforts, as ‘Teaball’ data could pinpoint the location of downed aircrews, enabling rescue craft to arrive quickly.[27]

However, the program, literally operating out of the back of a van, was not without problems.[28] The ‘Iron Horse’ computer was powerful for its time, but processing the data of all the SIGINT and radar inputs took an average of two minutes – an eternity in a dogfight. For this reason, ‘Teaball’s’ role was limited to providing early warning only. Once combat began, most pilots relied on more timely information from ‘Disco’ or ‘Red Crown’ if in range.[29] Also, the UHF radio relays in F-4 cockpits were old and broke down frequently.[30]

Increased American success forced the North Vietnamese Air Force to scale back its operations, flying fewer missions and attempting to counter ‘Teaball’s’ tracking ability by turning off their IFF (Identify-Friend-or-Foe) signals. However, that separated North Vietnamese pilots from their GCI, their chief advantage to this point. They could run with radio silence, but that risked making them vulnerable to their surface-to-air missiles (SAMs). ‘Teaball’ operators could spot them as soon as they tried to alert their missile sites. The more common technique the North Vietnamese used to get around ‘Teaball’ was deception. Ground controllers sent messages pretending to be pilots, essentially creating ‘ghost MiGs.’ However, ‘Teaball’s’ operators could easily distinguish between these fake calls and authentic ones due to differences in the signal itself.[31]

When LINEBACKER ended, so did most air-to-air combat, but ‘Teaball’ stood ready when LINEBACKER II commenced on 18 December 1972. Lieutenant General Horace Wade, Vice Chief of Staff of the Air Force, was impressed enough with ‘Teaball’ to move it into a permanent facility at Nakom Phenom.[32] However, MiGs barely flew during the operation – only 26 were even sighted. USAF Phantoms took down four, the US Navy got one more, and B-52 gunners shot down two. USAF lost two Phantoms to MiGs. North Vietnamese sources claim that MiGs shot down two B-52s as well, but this is unconfirmed by the U.S.[33] This 3.5:1 is above average for the war, if not as impressive as when ‘Teaball’ was most active in LINEBACKER. However, the sample size for LINEBACKER II is incredibly small, and the operation was unique. In any case, although SAMs wreaked havoc on the B-52 fleet, MiGs did not pose a significant threat. By 28 December 1972, North Vietnam had exhausted its SAM supply and was incapable of defending itself from the B-52 raids. When Hanoi expressed its desire to renew serious negotiations, President Nixon halted all bombing north of the 20th parallel. With the signing of final settlements on 23 January 1973, air-to-air combat in the Vietnam War ended.[34]

Conclusion

The typical, perhaps romanticised narrative of air combat in Vietnam is that the US Navy used the ‘correct’ approach when creating the Top Gun program and that the USAF deserves criticism for its failure to produce a similar program and its adherence to technological chimeras. However, this story ignores that the US Navy also used technological improvements, including upgrades to their missiles and the jamming of enemy communications. It fails to note that the US Navy engaged fewer MiGs during the LINEBACKER period, with little contact with the more advanced MiG-21 Fishbed, so perhaps a direct comparison of each service’s kill counts is misleading.

Furthermore, this narrative fails to recognise that the USAF saw a more significant improvement in its effectiveness than did the US Navy in the same period owing to the systems-based, technological approach of Project Teaball. Top Gun worked, but ‘Teaball’ worked better. The role performed by ‘Teaball’ laid the foundation for the later role of Airborne Warning and Control Systems (AWACS) that has become an essential element of American air power strategy. In the final phase of the Vietnam War, the USAF demonstrated that technological solutions could be effective.

See also, István Toperczer, Mig-21 Units of the Vietnam War and MiG-17 and MiG-19 Units of the Vietnam War, both from Osprey Press. Toperczer and Boniface each claimed to have examined North Vietnamese records, but make no mention or citation of specific documents, and their work has not been peer reviewed. Naturally their claims for NVAF victories are significantly higher that official US records. While their claims may have merit, this article has chosen to rely on official US records where possible, admitting that these are also not perfect.
