The Brewster F2A Buffalo[1] was an American fighter aircraft which saw service early in World War II. Designed and built by the Brewster Aeronautical Corporation, it was one of the first U.S. monoplanes with an arrestor hook and other modifications for aircraft carriers. The Buffalo won a competition against the Grumman F4F Wildcat in 1939 to become the U.S. Navy's first monoplane fighter aircraft. Although superior to the Grumman F3F biplane it replaced and the early F4Fs,[2] the Buffalo was largely obsolete when the United States entered the war, being unstable and overweight, especially when compared to the Japanese Mitsubishi A6M Zero.[3]

Several nations, including Finland, Belgium, Britain and the Netherlands, ordered the Buffalo. The Finns were the most successful with their Buffalos, flying them in combat against early Soviet fighters with excellent results.[4] During the Continuation War of 1941–1944, the B-239s (a de-navalized F2A-1) operated by the Finnish Air Force proved capable of engaging and destroying most types of Soviet fighter aircraft operating against Finland at that time and achieving in the first phase of that conflict 32 Soviet aircraft shot down for every B-239 lost,[5] and producing 36 Buffalo "aces".[6]

In December 1941, Buffalos operated by both British Commonwealth (B-339E) and Dutch (B-339D) air forces in South East Asia suffered severe losses in combat against the Japanese Navy's Mitsubishi A6M Zero and the Japanese Army's Nakajima Ki-43 "Oscar". The British attempted to lighten their Buffalos by removing ammunition and fuel and installing lighter guns to improve performance, but it made little difference.[7] After the first few engagements, the Dutch halved the fuel and ammunition load in the wing, which allowed their Buffalos (and their Hurricanes) to stay with the Oscars in turns.[8]

The Buffalo was built in three variants for the U.S. Navy: the F2A-1, F2A-2 and F2A-3. (In foreign service, with lower horsepower engines, these types were designated B-239, B-339, and B-339-23 respectively.) The F2A-3 variant saw action with United States Marine Corps (USMC) squadrons at the Battle of Midway. Shown by the experience of Midway to be no match for the Zero,[2] the F2A-3 was derided by USMC pilots as a "flying coffin."[9] However, the F2A-3s performance was substantially inferior[10] to the F2A-2 variant used by the Navy before the outbreak of the war despite detail improvements.

Design and development

United States Navy

In 1935, the U.S. Navy issued a requirement for a carrier-based fighter intended to replace the Grumman F3F biplane. The Brewster XF2A-1 monoplane, designed by a team led by Dayton T. Brown, was one of two aircraft designs that were initially considered.[11] The XF4F-1 with a double-row radial engine was a "classic" biplane. The U.S. Navy competition was re-opened to allow another competitor, the XFNF-1, a navalized Seversky P-35 eliminated early on when the prototype could not reach more than 267 mph (430 km/h).[12] The XF2A-1 first flew on 2 December 1937 and early test results showed it was far in advance of the Grumman biplane entry. While the XF4F-1 would not enter production, it would later re-emerge as a monoplane, the Wildcat.

The Buffalo was manufactured at the Brewster Building in Long Island City, New York.

Brewster XF2A-1 prototype

The new Brewster fighter had a modern look with a stubby fuselage, mid-set monoplane wings and a host of advanced features. It was all-metal, with flush-riveted, stressed aluminum construction, although control surfaces were still fabric-covered. The XF2A-1 also featured split flaps, a hydraulically operated retractable main undercarriage (and partially retractable tailwheel), and a streamlined framed canopy. However (as was still common at this time), the aircraft lacked self-sealing fuel tanks and pilot armor. Fuel was only 160 U.S. gal (606 l), stored in the fuselage. Powered by a 950 hp (708 kW) single-row Wright R-1820-22 Cyclone radial engine, it had an impressive initial climb rate of 2,750 ft/min and a top speed of 277.5 mph (447 km/h). The aircraft was then tested in 1938 in the Langley Research Center full-scale wind tunnel, where it was determined that certain factors were contributing to parasitic drag. Based on the tests, improvements were made to the cowling streamlining and carburetor/oil cooler intakes, and the Buffalo's speed rose to 304 mph (489 km/h) at 16,000 ft (4,879 m) without any increase in power.[13][14][15] Other manufacturers took notice of this 10% increase in speed and efficiency, and wind tunnel tests grew to be standard procedure in the US.[16] With only a single-stage supercharger, high-altitude performance fell off rapidly.[10] Fuselage armament was one fixed .50 in (12.7 mm) M2 Browning machine gun with 200 rounds and one fixed .30 in (7.62 mm) AN Browning machine gun with 600 rounds, both in the nose.[N 1] The Navy awarded Brewster Aeronautical Corporation a production contract for 54 aircraft as the F2A-1.

Service testing of the XF2A-1 prototype began in January 1938 and in June, production started on the F2A-1. They were powered by the 940 hp (701 kW) Wright R-1820-34 engine and had a larger fin. The added weight of two additional .50 in (12.7 mm) Browning wing guns and other equipment specified by the Navy for combat operations reduced the initial rate of climb to 2,600 ft/min. Plagued by production difficulties, Brewster delivered only 11 F2A-1 aircraft to the Navy; the remainder of the order was later diverted to the Finnish Air Force in modified form under the export designation Model 239.

A later variant, the F2A-2, of which 43 were ordered by the U.S. Navy, included a more powerful R-1820-40 engine, a better propeller, and integral flotation gear, but still lacked pilot armor and self-sealing tanks. The increase in engine power was welcomed, but to some extent offset by the increased loaded weight (5,942 lb/2,701 kg) of the aircraft; while top speed was increased to a respectable 323 mph (520 km/h) at 16,500 ft (5,029 m), initial climb rate dropped to 2,500 ft/min. Both the F2A-1 and the F2A-2 variants of the Brewster were liked by early Navy and Marine pilots, including Pappy Boyington, who praised the good turning and maneuvering abilities of the aircraft.[17] Boyington is alleged to have opined "...the early models, before they weighed it all down with armor plate, radios, and other [equipment], they were pretty sweet little ships. Not real fast, but the little [aircraft] could turn and roll in a phone booth." This might be expected from the low wing loading, in earlier versions comparable with the Mitsubishi A6M Zero's 22 pounds per square foot.[18]

The F2A-3 was the last version of the Buffalo to enter service with the U.S. Navy and Marine Corps. A total of 108 examples were ordered in January 1941. By this time, the Navy had become disenchanted with the Buffalo, and had become especially annoyed at Brewster Aeronautical Corporation's frequent production delays and its seemingly never-ending management difficulties. This order was seen more as a way of keeping Brewster's production lines running; they would eventually build Corsair fighters for the Navy as well as Buccaneer/Bermuda dive bombers.

The F2A-3s were conceived as a long range reconnaissance fighter with a new wet wing with self-sealing features and a larger fuselage tank which provided increased fuel capacity and protection, but this also increased the aircraft's weight by more than 500 lb (227 kg).[10] The wing and enlarged fuselage tank carried an additional 80 U.S. gal (300 L) of fuel; at 6 lb/U.S. gal (0.72 kg/L), the fuel alone weighed nearly 500 lb (227 kg). The addition of armor plating for the pilot and increased ammunition capacity further increased the aircraft's weight, resulting in a reduced top speed and rate of climb, while substantially degrading the Brewster's turning and maneuvering capability.[10] The Navy found that the added weight of the F2A-3 also aggravated the problem of landing gear failure during carrier landings. However, the -40 two speed [19] supercharged Cyclone engine in the F2A-3 was an excellent "cruising" engine and as such the F2A-3 had some value and saw initial service on the carriers Saratoga and Lexington.

Even in late 1940 it was apparent that the Buffalo was rapidly becoming obsolete.[N 2] It badly needed a more powerful engine, but the limits of the airframe had been reached, making installation of a larger engine impossible. Soon after deliveries of the F2A-3 began, the Navy decided to eliminate the type altogether. By then, considered a second line aircraft, some were transferred to the U.S. Marine Corps, which deployed two F2A-3 squadrons to the Pacific, one at Palmyra Atoll, and another at Midway Island. Those which still remained on board aircraft carriers narrowly missed a combat opportunity when a relief mission was dispatched to Wake Island, but the relief force was withdrawn before completing the mission. Shortly thereafter, F2A-3s still in naval service were transferred to training squadrons for use as advanced trainers.

Operational history

The first unit to be equipped with the F2A-1 was Lt. Cdr. Warren Harvey’s VF-3, assigned to USS Saratoga air group. On 8 December 1939, VF-3 received 10 of the 11 Buffalos delivered to the U.S. Navy.[20] The remaining 43 F2A-1s were declared surplus and sold to Finland.[21] Although it was becoming clear the F2A was inferior to the latest German and British fighters—one American observer wrote in late 1940 after visiting Britain that "The best American fighter planes already delivered to the British are used by them either as advanced trainers --or for fighting equally obsolete Italian planes in the Middle East. That is all they are good for"[22]—in the early years of World War II all modern monoplane fighter types were in high demand. Consequently, the United Kingdom, Belgium, and the Netherlands East Indies purchased several hundred export models of the Buffalo.[23]


Finnish company Nokia donated sufficient funds for the FAF to purchase a B-239. In return, the word NOKA was inscribed on BW-355. Operated by No. 24 Squadron, it was destroyed on 24 October 1944.[24] Future ace Paavo Mellin shot down an I-16 and shared in the destruction of a MiG-3 whilst flying this aircraft.[25] In April 1939, the Finnish government contacted the Roosevelt administration to acquire modern combat aircraft for its air force as quickly as possible. On 17 October 1939, the Finnish Embassy in Washington, DC, received a telegram clearing the purchase of fighter aircraft. Prompt availability and compatibility with 87-octane fuel were the only requirements stipulated by the Finns.[26] The U.S. Navy and State Department arranged to divert remaining F2A-1 fighter aircraft,[N 3] in exchange for its order of F2A-2 Buffalos scheduled to be delivered later.

Consequently, on 16 December, the Finns signed a contract to purchase 44 Model 239 fighters.[26] The total agreed price was U.S. $3.4 million, and the deal included spare parts, ten replacement engines and 20 Hamilton Standard propellers.[26] The Buffalos sent to Finland were de-navalized; all the naval equipment, such as tailhooks and life-raft containers were removed, resulting in a lighter aircraft.[27] The Finnish F2A-1s also lacked self-sealing fuel tanks and cockpit armor.

These F2A-1 Buffalos, given the export number Model B-239, were equipped with an export-approved Wright R-1820-G5 nine-cylinder radial engine of 950 hp (708 kW).[27] After their delivery to Finland, the Finnish Air Force added armored backrests, metric flight instruments, the Finnish Väisälä T.h.m.40 gunsight, and four .50 in (12.7 mm) machine guns. The top speed of the Finnish B-239s, as modified, was 297 mph (478 km/h) at 15,675 ft (4,750 m), and their loaded weight was 5,820 lb (2,640 kg).[11][28]

Built and shipped in four batches, the Finnish B-239s were shipped to Bergen, in Norway, in January and February 1940 from New York City. The crated fighters were then sent by railway to Sweden and assembled by SAAB at Trollhättan, northeast of Gothenburg.[29]

In February 1940, Finnish Air Force pilot Lieutenant Jorma "Joppe" Karhunen flight tested the first B-239.[11][30] Unfamiliar with the aircraft, he burned out the engine while flying very low at high speed; crashing on a snow-covered field, damaging the propeller and some belly panels.[11][30] Initially unimpressed, the Finns later witnessed a demonstration by a Brewster test pilot, who was able to stay on the tail of a Finnish Fiat G.50 Freccia [N 4] fighter from Italy; although the Fiat fighter was faster in level flight,[N 5] the Brewster could out-turn it.[31]

Of the six Buffalo B-239 fighters delivered to Finland before the end of the Winter War of 1939–1940, five of them became combat-ready, but they did not enter combat before the war ended.

The Brewster B-239E fighter aircraft was never referred to as the "Buffalo" in Finland; it was known simply as the "Brewster" or sometimes by the nicknames Taivaan helmi ("Sky Pearl") or Pohjoisten taivaiden helmi ("Pearl of the Northern Skies"). Other nicknames were Pylly-Valtteri, Amerikanrauta ("Butt-Walter" and "American hardware" or "American car", respectively) and Lentävä kaljapullo ("flying beer-bottle"). The 44 Buffalo Model B-239 (export) fighters used by the FAF received serial numbers BW-351 to BW-394.

In Finnish Air Force service, the B-239s were regarded as being easy to fly, a "gentleman's travelling plane."[32] The Buffalo was also popular within the FAF because of its relatively long range and also because of a good maintenance record. This was in part due to the efforts of the Finnish mechanics, who solved a problem that plagued the Wright Cyclone engine by inverting one of the piston rings in each cylinder, which had a positive effect on reliability. The cooler weather of Finland also helped, because the engine was prone to overheating as noted in tropical Pacific use. The Brewster Buffalo earned a reputation in Finnish Air Force service as one of their more successful fighter aircraft, with the Fiat G.50, that scored an unprecedented kill/loss ratio of 33/1.[33]

In service from 1941 to 1945, Buffalos of Lentolaivue 24 (Fighter Squadron 24) claimed 477 Soviet Air Force warplanes destroyed, with the combat loss of just 19 Buffalos, an outstanding victory ratio of 26:1.[34]

During the Continuation War, Lentolaivue 24 (Fighter Squadron 24) was equipped with the B-239s until May 1944, when the Buffalos were transferred to Hävittäjälentolaivue 26 (Fighter Squadron 26). Most of the pilots of Lentolaivue 24 were Winter War combat veterans. This squadron claimed a total of 459 Soviet aircraft with B-239s, while losing 15 Buffalos in combat.[11]

The Brewsters had their baptism by fire in Finland on 25 June 1941, when a pair of Buffalos from 2/LLv24 intercepted 27 Soviet Tupolev SBs from 201st SBAP [N 6] over Turku. Five SBs were claimed as downed. Subsequent attacks were repelled by LLv24 pilots who, by dusk, had flown 77 missions.[35]

Many Finnish pilots racked up enormous scores by using basic tactics against Soviet aircraft. The default tactic was the four-plane "parvi" (swarm), with a pair flying lower as bait, and a higher pair to dive on enemy interceptors. The Soviet Air Force was never able to counteract this tactic. The top-scoring B-239 pilot was Hans Wind, with 39 kills.[36] Lt Hans Wind, with six other Buffalos of LeLv 24, intercepted some 60 Soviet aircraft near Kronstad. Two Russian Pe-2 bombers, one Soviet Hawker Hurricane fighter, and 12 I-16s were claimed for the loss of just one B-239 (BW-378).[37] After evaluation of claims against actual Soviet losses, aircraft BW-364 was found to have been used to achieve 42½ kills in total by all pilots operating it, possibly making it the highest-scoring fighter airframe in the history of air warfare. The top scoring Finnish ace, Ilmari Juutilainen, scored 34 of his 94½ kills in B-239s, including 28 in BW-364.[38]

During the Continuation War, a lack of replacements led the Finns to develop a copy of the Buffalo built from non-strategic materials such as plywood, however the Humu, as they called it, was already obsolete and only a single prototype was built. By late 1943, the lack of spares, wear-and-tear, and better Soviet fighters and training greatly reduced the effectiveness of Finnish B-239s, though LeLv 26 pilots would still claim some 35 victories against Soviet aircraft in mid-1944. The last victory by a Buffalo against Soviet aircraft was claimed over the Karelian Isthmus on 17 June 1944.[23]

From 1943, Finland's air force received Messerschmitt Bf 109Gs from Germany, and this much-superior fighter re-equipped most Finnish Air Force fighter squadrons.

After Finland signed an armistice with the Soviet Union in September, 1944, they had to drive Finland's former ally, Nazi Germany out of the country during the "Lapland War". The only clash with the Luftwaffe took place on 3 October 1944 when HLeLV 26 intercepted Junkers Ju 87s, claiming two, the last victories to be made by Brewster pilots in World War II.[39] By the end of the war in Lapland, only eight B-239s were left.

Five B-239s continued to fly until 1948, with last flights of Brewsters by the Finnish Air Force on 14 September 1948, when they were stored until scrapped in 1953.[40]


Just before the start of the war, Belgium sought more modern aircraft to expand and modernize its air force. Belgium ordered 40 Brewster B-339 aircraft, a de-navalized F2A-2, fitted with the Wright R-1820-G-105 engine approved for export use. The G-105 engine had a power output of 1,000 hp (745.7 kW) (peak) on takeoff, some 200 hp (149 kW) less than the engine fitted to the U.S. Navy F2A-2. The arrestor hook and liferaft container were removed, and the aircraft was modified with a slightly longer tail.

Only one aircraft[41][42][N 7] reached France by the time Germany launched its Blitzkrieg in the West on 10 May 1940. The Buffalo was later captured intact by the Germans.

Six more Belgian Brewsters were offloaded at the French Caribbean island of Martinique and languished on a coastal hillside, never to be flown.[43] The rest of the order went to the RAF.

British Commonwealth (Malaya)

Facing a shortage of combat aircraft in January 1940, the British government established the British Purchasing Commission to acquire U.S. aircraft that would help supplement domestic production. Among the U.S. fighter aircraft that caught the Commission's attention was the Brewster. The remaining 32 B-339 aircraft ordered by the Belgians, suspended at the fall of France, were passed on to the United Kingdom.[44] Appraisal by Royal Air Force acceptance personnel criticized it on numerous points including inadequate armament and lack of pilot armor, poor high-altitude performance, engine overheating, maintenance issues, and cockpit controls, while it was praised for its handling, roomy cockpit, and visibility.[11] With a top speed of about 323 mph (520 km/h) at 21,000 ft (6,400 m), but with fuel starvation issues over 15,000 ft (4,600 m), it was considered unfit for duty in western Europe.[11] Still desperately in need of fighter aircraft in the Pacific and Asia for British and Commonwealth air forces, the UK ordered an additional 170 aircraft under the type specification B-339E.[45] The aircraft were sent to Royal Australian Air Force, RAF and Royal New Zealand Air Force fighter squadrons in Singapore, Malaya and Burma, shortly before the outbreak of war with Japan.

Brewster B-339E (AN196/WP-W) of No. 243 Squadron RAF. This aircraft was flown by Flying Officer Maurice Holder, who flew the first Buffalo sortie in the Malayan Campaign on 8 December 1941, strafing landing barges on the Kelantan River.[46] Damaged by ground fire, it was abandoned at RAF Kota Bharu before its fall to the Japanese.[46] The B-339E, or Brewster Buffalo Mk I as it was designated in British service, was initially intended to be fitted with an export-approved Wright R-1820-G-105 Cyclone engine with a 1,000 hp (745.7 kW) (peak takeoff) engine.[47][N 8] The Brewster aircraft delivered to British and Commonwealth air forces were significantly altered from the B-339 type sold to the Belgium and French forces in accordance with their purchase order. The Brewster factory removed the Navy life raft container and arrestor hook, while adding many new items of equipment, including a British Mk III reflector gun sight, a gun camera, a larger fixed pneumatic tire tail wheel, fire extinguisher, engine shutters, a larger battery, and reinforced armor plating and armored glass behind the canopy windshield.[48]

The Brewster Model B-339E, as modified and supplied to Great Britain was distinctly inferior in performance to the F2A-2 (Model B-339) from the original order. It had a less powerful (1,000 hp (745.7 kW)) engine compared to the F2A-2's 1,200 hp (895 kW) Cyclone, yet was substantially heavier due to all of the additional modifications (some 900 lb/400 kg). The semi-retractable tail wheel had been exchanged for a larger fixed model, which was also less aerodynamic. Top speed was reduced from 323 mph (520 km/h) to 313 mph (504 km/h) at combat altitudes.[11]

Brewster B-339E wrecks cannibalized for parts, probably in Singapore circa late January 1942. Two of the Buffalos, serials W8156 and W8207, were operated by 453 Squadron RAAF.[49]

In its original form, the B-339 had a theoretical maximum speed of 323 mph (520 km/h) at a rather unrealistic 21,000 ft (6,400 m), but fuel starvation problems and poor supercharger performance at higher altitudes meant that this figure was never achieved in combat; the B-339E was no different in this regard. Its maneuverability was severely impaired (the aircraft was unable to perform loops), and initial rate of climb was reduced to 2,300 ft/min. The Wright Cyclone 1890-G-105 engine designated for use in the Brewster Mk I was in short supply; many aircraft were fitted with secondhand Wright engines sourced from Douglas DC-3 airliners and rebuilt to G105 or G102A specifications by Wright.[45] In service, some effort was made by at least one Brewster squadron to improve the type's sluggish performance; a few aircraft were lightened by some 1,000 lb (450 kg) by removing armor plate, armored windshields, radios, gun camera, and all other unnecessary equipment, and by replacing the .50 in (12.7 mm) machine guns with .303 in (7.7 mm) machine guns.[50] The fuselage tanks were filled with a minimum of fuel, and run on high-octane aviation petrol where available. At Alor Star airfield in Malaya, the Japanese captured over 1,000 barrels (160 m3) of high-octane aviation petrol from British forces, which they promptly used in their own fighter aircraft.[51]

Many of the pilots assigned the Buffalo lacked adequate training and experience in the type. A total of 20 of the original 169 Buffalos were lost in training accidents during 1941. By December 1941, approximately 150 Buffalo B-339E aircraft made up the bulk of the British fighter defenses of Burma, Malaya and Singapore. The two RAAF, two RAF, and one RNZAF squadrons, during December 1941-January 1942, were beset with numerous problems,[52] including poorly built and ill-equipped aircraft.[11] Aviation historian Dan Ford characterized it as, "The performance... was pathetic." Inadequate spare parts and support staff, airfields that were difficult to defend against air attack, lack of a clear and coherent command structure, a Japanese spy in the Army air liaison staff, antagonism between RAF and RAAF squadrons and personnel, and inexperienced pilots lacking appropriate training would lead to disaster. Although the Mk I had .50-inch guns, many aircraft were equipped with .30 Browning mounts and electric firing solenoids, which tended to fail in service.[45]

Buffalos of No. 453 Squadron RAAF lined up at RAF Sembawang in November 1941. Buffalo AN185/TD-V was flown by Flt Lt Doug Vanderfield, who shot down three Japanese bombers (two Ki-48s and one Ki-51) over Butterworth, Penang on 13 December 1941, while his undercarriage was still down.[53]

When the Japanese invaded northern Malaya on 8 December 1941, the B-339E initially performed adequately. Against the Nakajima Ki-27 "Nate", the overloaded Brewsters could at least hold their own if given time to get to altitude, and at first achieved a respectable number of kills. However, the appearance of ever greater numbers of Japanese fighters, including markedly superior types such as the Nakajima Ki-43 "Oscar" soon overwhelmed the Buffalo pilots, both in the air and on the ground. Another significant factor was the Brewster engine's tendency to overheat in the tropical climate, which caused oil to spray over the windscreen, usually forcing an aborted mission and greatly complicating attempts to intercept and destroy enemy aircraft. In the end, more than 60 Brewster Mk I (B-339E) aircraft were shot down in combat, 40 destroyed on the ground, and approximately 20 more destroyed in accidents. Only about 20 Buffalos survived to reach India or the Dutch East Indies.[54] The last airworthy Buffalo in Singapore flew out on 10 February, five days before the island fell.[55]

It is not entirely clear how many Japanese aircraft the Buffalo squadrons shot down, although RAAF pilots alone managed to shoot down at least 20.[56] Eighty were claimed in total, a ratio of kills to losses of just 1.3 to 1. Additionally, most of the Japanese aircraft shot down by the Buffalos were bombers.[45] The Hawker Hurricane, which fought in Singapore alongside the Buffalo from 20 January, also suffered severe losses from ground attack; most were destroyed.[57] The Fleet Air Arm also used the Buffalo in the Mediterranean in the Battle of Crete in early 1941.

The Brewster Mark I produced four Commonwealth aces: Geoff Fisken, Maurice Holder, A. W. B. (Alf) Clare and R. D. (Doug) Vanderfield.[58] New Zealander Fisken, the top-scoring pilot, later flew RNZAF P-40s and became the highest-scoring Commonwealth pilot within the Pacific theatre.


No. 67 Squadron RAF was equipped with thirty Buffalos when the Japanese invaded Burma. They were joined by Curtiss P-40 fighters of the American Volunteer Group (Flying Tigers). AVG crews were initially impressed with the Buffalo, some even urging General Claire Chennault to trade a squadron of P-40s for Buffalos.[59] In response, Chennault arranged a mock dogfight between both fighters, with 1st Lieutenant Erik Shilling flying the P-40 and Squadron Leader Jack Brandt flying the Buffalo.[59] Over their training base in Toungoo, the P-40 proved to be superior to the Buffalo.[59] When Shilling and Brandt met again fifty years later, the RAF pilot said, "how I wish I could have swapped my aircraft for yours".[59]

The Buffalos and P-40s carried out air defences over Rangoon and Mingaladon as well as strafing missions on Japanese airfields.[60] Like Malaya and Singapore, lack of effective early warning systems greatly hampered British and AVG efforts to defend Burma from air raids.[60] Reports of Japanese aircraft performance from the Malayan Campaign prompted Buffalo pilots in Burma to employ different tactics; according to Flight Sergeant Vic Bargh, "come in from above, or at the same level at the very least, then dive away before they got onto you, because if they did get onto you, well, you were shot down".[61] One of the Buffalo's final victories of the Burma Campaign was claimed by Bargh; he found the wreckage of the bomber and had his picture taken with it as proof.[62]

The IJAAF secured air superiority over Rangoon by early February 1942, and with the situation on the ground rapidly deteriorating, No. 67 Squadron withdrew north to Toungoo.[62] On 13 February, the squadron moved further north to Magwe with only eight Buffalos, where they continued to carry out reconnaissance flights as well as escorting Westland Lysanders on ground attack missions.[62] The Buffalo flew its last combat sortie with the RAF on 5 March, escorting Hawker Hurricanes and Bristol Blenheims for an attack on a Japanese airbase in Chiang Mai, Thailand.[62] Only six Buffalos remained when the squadron withdrew to Calcutta, India on 11 March to re-equip with Hurricanes.[63] They were swiftly relegated to training duties, though two were briefly acquired by No. 146 Squadron RAF in early April, one of which was regularly flown by Squadron Leader Count Manfred Czernin.[63] No. 67 Squadron claimed 27 Japanese aircraft destroyed; eight Buffalos were shot down and eight pilots were killed.[63] For their actions, Squadron Leader Jack Brandt and Flight Lieutenant Colin Pinckney were awarded the Distinguished Flying Cross (the latter posthumously), while Sergeant Gordon Williams received the Distinguished Flying Medal.[63]

Netherlands East Indies

The Militaire Luchtvaart van het Koninklijk Nederlands-Indisch Leger ("Military Air Service of the Royal Netherlands East Indian Army", ML-KNIL) had ordered 144 Brewster B-339C and 339D models, the former with rebuilt Wright G-105 engines supplied by the Dutch and the latter with new 1,200 hp (895 kW) Wright R-1820-40 engines Brewster purchased from Wright. At the outbreak of war, only 71 had arrived in the Dutch East Indies, and not all were in service. A small number served briefly at Singapore before being withdrawn for the defense of Borneo and Java.

As the Brewster B-339 aircraft used by the ML-KNIL were lighter than the modified B-339E Brewster Mark Is used by British, Australian, and New Zealand air forces, they were able to successfully engage the Japanese Army Nakajima Ki-43 "Oscar", although both the "Oscar" and the Japanese Navy's A6M Zero still out-climbed the B-339 at combat altitudes (the Zero was faster as well).[64] After the first few engagements, the Dutch halved the fuel and ammo load in the wing, which allowed their Buffalos (and their Hurricanes) to stay with the Oscars in turns.[8] In February 1942 they received new model gunsights. Around the same time the Dutch started to use tracer ammunition as well. These two improved their hit ratio. Still, their lack of heavy machine guns (.50") meant their success rate wasn't as high as it could have been.[8]

Apart from their role as fighters, the Brewster fighters were also used as dive bombers against Japanese troopships. Although reinforced by British Commonwealth Brewster Mk I (B-339E) aircraft retreating from Malaya, the Dutch squadrons faced superior numbers in the air, usually odds of one against two or three. Timely early warning from British radar would have countered this deficit, especially in avoiding unnecessary losses from raids on airfields, but the British government had decided too late to send these: the first British radar stations became operational only towards the end of February. Had they been ready two weeks earlier, the outcome of the Japanese invasion here might well have been different (read Boer's book).

In a major engagement above Semplak on 19 February 1942, eight Dutch Brewster fighters intercepted a formation of about 35 Japanese bombers with an escort of about 20 Zeros. The Brewster pilots destroyed 11 Japanese aircraft and lost four Brewsters; two Dutch pilots died.[65]

Only four airworthy Buffalos remained on 7 March.[55] Capt. Jacob van Helsdingen led this flight on its final sortie that day, and was credited with a Zero before he was killed.[55] This made him and Lt. August Deibel the most successful Dutch pilots on the Buffalo with three victories each.[55] Altogether, 17 ML-KNIL pilots were killed, and 30 aircraft shot down; 15 were destroyed on the ground, and several were lost to misadventure. Dutch pilots claimed 55 enemy aircraft destroyed.[58]

USAAF/RAAF in Australia

Following the surrender of the Netherlands East Indies on 8 March 1942, 17 Buffalos belonging to the ML-KNIL were transferred to the U.S. Fifth Air Force in Australia. All of these USAAF aircraft were lent to the RAAF, with which they were used mainly for air defence duties outside frontline areas, photo-reconnaissance and gunnery training.[66] Buffalos served with 1 PRU, 24 Sqn, 25 Sqn, 85 Sqn and the RAAF Gunnery Training School.[66]

Between August 1942 and November 1943, 10 of these Buffalos constituted the air defence force for Perth, Western Australia, while assigned to 25 and 85 Sqns at RAAF Pearce and RAAF Guildford. In 1944, all of the surviving aircraft were transferred to the USAAF.[56]

U.S. Marine Corps

At Midway Island, United States Marine Corps fighter squadron VMF-221 operated a mixed group of 20 Brewster F2A-3 Buffalos and seven Grumman F4F-3 Wildcats.[67] They were originally assigned to the USS Saratoga as part of a relief force bound for Wake Island, but were diverted to Midway instead after the force was controversially recalled on 22 December 1941. Wake Island fell on the following day.[68] The squadron first saw action on 10 March 1942 when a Kawanishi H8K "Emily" flying boat was shot down by Captain James L. Neefus near Midway, the Buffalo's first kill in U.S. service.[69][70][71][72]

During the Battle of Midway in 1942, VMF-221 was destined to participate in one of the few aerial combats involving the Buffalo in U.S. military service. The initial Buffalo interception of the first Japanese air raid was led by Major Floyd B. Parks, whose 13-aircraft division did not fly in paired flights of mutually supporting aircraft. After attacking a formation of 30-40 Aichi D3A1 "Val" dive bombers escorted by 36 Zeros, the Marines, flying in two divisions of aircraft, downed several Japanese bombers before the escorting Zeros reacted; a furious dogfight developed. Thirteen out of 20 Buffalos were lost;[73] of the six Wildcats, only two remained flyable at the end of the mission. The losses included the Marine air commander, Major Parks, who bailed out of his burning Buffalo, only to be strafed by Zeros after parachuting into the sea.[67]

The Marine pilots who managed to shake off the Zeros used high speed split-s turns or very steep dives.[67] These maneuvers were later found to be the best means to evade pursuit by the highly maneuverable Japanese fighters. One F2A-3 pilot, Marine Captain William Humberd, dove away from his pursuers, then attacked a Zero in a head-on pass, shooting his opponent down.[74] In the battle, some F2A-3s suffered from inoperative guns.[11] The nose-mounted guns' occasional failure to fire was noticed by other users as well; the phenomenon may have been caused by frayed electrical wires in the mechanism that synchronized the nose guns with the propeller. Other Buffalos had not been fitted with plate armor behind the pilot, making them vulnerable to even a single bullet or shell. Losses were aggravated due to the Japanese practice of strafing pilots who had bailed out.[67]

  Second Lt. Charles S. Hughes, whose Buffalo was forced to retire at the start of the raid due to engine trouble, had a ringside view of the aerial combat:
The Zeros came in strafing immediately afterward. I saw two Brewsters trying to fight the Zeros. One was shot down and the other was saved by ground fires covering his tail. Both looked like they were tied to a string while the Zeros made passes at them.[75]
Second Lt. Charles M. Kunz reported that after successfully downing two Val bombers, he was attacked by Japanese fighters:
I was at an altitude of about 9,000 ft, and shoved over in a dive trying to shake the plane on my tail until I was about 20 feet from the water. I was making radical turns hoping the pilot couldn't get steadied on me. I glanced out of the rear and saw that it was a Zero fighter. I continued flying on a rapid turning course at full throttle when I was hit in the head by a glancing bullet. After he fired a few short burst he left as I had been in a general direction of 205 degrees heading away from the island. My plane was badly shot up... In my opinion the Zero fighter has been far underestimated. I think it is probably one of the finest fighters in the present war. As for the F2A-3, (or Brewster trainer) it should be in Miami as a training plane, rather than used as a first line fighter.[74]
Claire Chennault's report on the Zero and air combat reached Washington in 1941, where it was disseminated to aviation forces of the U.S. Army and Navy.[76] This information, along with the development of two-plane mutual defensive formations and tactics, were incorporated into U.S. and Marine Corps air combat training doctrine by some prescient U.S. commanders, including Lieutenant Commander "Jimmy" Thach. The Thach Weave was developed for use by Wildcat pilots against the Zero, and was later adopted by other Wildcat squadrons in the Pacific.[76]


With the emergence of new tactics for the F4F-3 and F4F-4 Wildcat (which was superior in all respects to the F2A-3 Buffalo, with the sole exception of maximum range), the Battle of Midway marked the end of the Buffalo in both U.S. Navy and Marine Corps fighting squadrons. Surviving F2A-3 aircraft were hastily transported to the U.S. mainland, where they were used as advanced trainers. The introduction in late 1943 of vastly superior American carrier-borne fighters such as the F6F Hellcat and Vought F4U Corsair soon relegated the Brewster F2A-3 to a distant memory.

Buffalo aces

The Finnish Air Force produced 36 Buffalo aces. The top three were Capt. Hans Wind, with 39 Buffalo air victories (out of 75), WO Eino Ilmari Juutilainen, with 34 (out of 94) and Capt. Jorma Karhunen, with 25.5 (out of 31.5). First Lt Lauri V. Nissinen also had victories in the type (22.5 out of 32.5).[6]

The non-Finnish Buffalo aces were: Geoff Fisken (RNZAF), with six air victories, and Doug Vanderfield (RAAF) with five individual kills, plus one shared. Alf Clare (RAAF) and Maurice Holder (RAF) had five victories each.[58][77]


Replica of Lt. Gerard Bruggink's B-339C at the National Military Museum in Soesterberg, Netherlands

Lauri Pekuri's FAF BW-372 at the Aviation Museum of Central Finland

There is currently one extant complete Finnish B-239 (BW-372), a restored B-239 fuselage mated to wooden wings with a Russian engine, a rebuilt variant VL-HUMU, and two static replicas- one in ML-KNIL markings and the other in U.S. Navy markings.

Finnish B-239 (serial no. BW-372) flown by Lt. Lauri Pekuri was damaged by a Russian Hawker Hurricane and crashed in 1942 on Lake Big Kolejärvi, about 31 mi (50 km) from Segezha, Russia and was rediscovered in 1998.

The aircraft was transported to the National Naval Aviation Museum at NAS Pensacola, Florida, USA on 18 August 2004. In early 2008 the aircraft was sent to the Aviation Museum of Central Finland for the 90th anniversary of the Finnish Air Force.[78]

In addition to BW-372, the hood and fin of FAF BW-393 (credited with 41 kills) survive in a Finnish museum; FAF BW-372 is on display at the Keski-Suomen Ilmailumuseo (Aviation Museum of Central Finland).[78]

In July 2008, a static full-scale replica B-339C was completed by the Cradle of Aviation Museum in Long Island, New York. The aircraft carries the markings of an ML-KNIL fighter flown by Lt. Gerard Bruggink (two kills). It was built for the Militaire-Luchtvaartmuseum (Military Aviation Museum) at Soesterberg, the Netherlands.[78][79] The Cradle of Aviation Museum houses a static full-scale replica/model F2A-2, carrying the markings of unit "201-S-13" from VS-201, aboard USS Long Island.[80]

In June 2012, divers discovered the partial wreckage of a Buffalo in shallow water just off Midway Atoll. The aircraft had been ditched during February 1942, after an aborted landing attempt in bad weather, by Lt. Charles W. Somers Jr. Officials at the Papahanaumokuakea Marine National Monument, where the wreckage was found, have not decided whether to recover any of the parts or leave them in place.[81]

In 1942, Indonesian pro-independence guerrillas captured a small number of aircraft at numerous air bases during the invasion of Japan to Dutch East Indies and saved them in remote areas for the preparation for incoming war. Most aircraft were destroyed in military conflicts between the Netherlands and the newly proclaimed-Republic of Indonesia during the Indonesian National Revolution of 1945-1949.


Captured Buffalos were repaired and test flown, both in Japanese markings, and - starring in recreated combat footage - in incorrect RAF markings.

Additional Information

It operated three aircraft plants, at the Brewster Building in Long Island City, New York, Newark, New Jersey, and, in 1941, in Warminster Township, Pennsylvania, which was then known as NAS Johnsville.

In early 1940, the British Purchasing Commission ordered a total of 170 Model 339Es in two separate contracts under the British designation Buffalo Mk. I. This was a major turnaround, since as recently as October of 1939 the British Air Ministry had declared the Brewster fighter as unsuitable for RAF use. However, they were deemed suitable for use in the Far East.

The 339E was basically a denavalized variant of the F2A-2, powered by an export-approved Wright R-1820-G105 Cyclone engine of 1100 hp. A number of changes were made to bring the aircraft up to current European combat standards: a British-built Mark III reflector gunsight replaced the ring-and-bead arrangement, armor plate was provided for the pilot, and armored glass was added to the wind screen. The Curtiss Electric cuffed propeller was replaced with a 10-foot one-inch Hamilton Standard propeller. The 339E was the only Buffalo variant to feature an internal gun camera. The small retractable naval-type tail wheel was replaced by a larger fixed tail wheel.

These changes brought the gross weight to 6500 pounds, almost a thousand pounds heavier than the standard F2A-2. The maximum speed was lowered to 330 mph and the rate of climb was lowered to only 2600 feet per minute. In addition, this increased weight raised the wing loading, increased the landing speed, and adversely affected the maneuverability. Another problem was that the Buffalo Mk. I did not use the same fuel line pressurization system as the F2A-2, and fuel starvation problems were often experienced above 18,000 feet.

The Wright Cyclone R-1820-G105 engine installed in the Buffalo Mk. I had been selected in part because there were sufficient numbers of this engine available at the time to meet the first British contract. However, when the second contract was issued, there were not enough new Cyclone engines available, and Brewster was forced to purchase used Cyclone engines from commercial airlines which had been using them to power their Douglas DC-3 airliners. These used engines were returned to Wright, which remanufactured them to -G105 standards.

The first three production Model 339Es were sent to Great Britain in April of 1941 for trials. The remaining Buffalos of the British order were shipped directly to the Far East to serve with units in Malaya, Singapore and Burma. The first Buffalos arrived in Singapore in the spring of 1941.

Five Commonwealth squadrons were formed around the Buffalo -- Nos. 67 and 243 Squadrons, RAF; Nos. 21 and 43 Squadrons of the RAAF; and No. 488 Squadron of the RNZAF. No. 67 Squadron was based in Burma and the other four were stationed at bases near Singapore. Each squadron was issued with 15 aircraft. A shortage of pilots prevented the formation of additional squadrons, and many Buffalos were placed in storage. Many of the pilots in the Commonwealth Buffalo squadrons were relatively new and inexperienced, and some 20 Buffalos were lost in training accidents during the autumn of 1941.

War in the Burma/Malaya theater began on December 8, 1941 with a Japanese landing on the Malayan coast. The Brewsters did experience some initial successes against Japanese Army Air Force Ki-27s and Ki-43s, and there were at least three Commonwealth pilots who became aces during this period. However, when the Japanese Navy A6M Reisen (Zero Fighter) appeared, the Buffalo was completely outclassed. The Zero was faster, more maneuverable and had a heavier armament. In an attempt to improve the Buffalo's performance, ground crews removed all unnecessary equipment to lower the weight, sometimes replacing the 0.50-inch machine guns with lighter 0.303-inch guns and reducing the ammunition and fuel load. However, these modifications did not even come close to closing the performance gap between the Buffalo and the Zero.

The situation in Malaya rapidly deteriorated as the Japanese advance gained momentum, and Commonwealth squadrons were forced to withdraw to Singapore Island. Attrition and combat losses took their toll, and by February of 1942 there were only a few airworthy Buffalos left. These were withdrawn to the nearby islands of the Netherlands East Indies. When the British evacuated the aircrews to Australis, at least four Buffalos were turned over to Dutch squadrons.

In Burma, No. 67 Squadron flew alongside the 3rd Squadron, American Volunteer Group (the famous 'Flying Tigers') in the defense of Rangoon. No. 67 Squadron had some initial successes against attacking Japanese bomber formations. However, attrition and the lack of spare parts steadily eroded the squadron's strength, and by the time that Rangoon fell, only six Buffalos were still airworthy. The surviving No. 67 Squadron Buffalos were evacuated to India, along with a few Hawker Hurricanes that had been rushed to Rangoon's defense. Some of the Buffalos that made it to India were taken on strength by No. 146 Squadron, RAF. There are even reports that at least one Buffalo was transferred to the Indian Air Force.

Many official British historical sources blame the loss of Malaya and Singapore largely on the Buffalo's poor performance. However, the picture is not entirely that of an unmitigated disaster, and many Buffalo-equipped units gave a good account of themselves before they were overwhelmed by superior Japanese numbers. Accurate figures on the combat losses of British Buffalos are difficult to come by. Approximately 60 to 70 Buffalos were lost in air combat, 40 were destroyed on the ground, twenty were lost in various non-combat related accidents, four were transferred to the Dutch, and six were evacuated to India. Commonwealth Buffalo squadrons claimed at least 80 kills, and some units may have achieved a 2-to-1 kill ratio.
