Brewster F2A Buffalo
The Brewster F2A Buffalo 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,〔Wheeler 1992, p. 58.〕 the Buffalo was largely obsolete when the United States entered World War 2 being unstable and overweight, especially when compared to the Japanese Mitsubishi A6M Zero.
Several nations, including Finland, Belgium, Britain and the Netherlands, ordered the Buffalo. Of all the users, the Finns were the most successful with their Buffalos, flying them in combat against early Soviet fighters with excellent results.〔Ethell 1995, p. 212.〕 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,〔Neulen 2000, p. 217.〕 and producing 36 Buffalo "aces".〔Stenman and Thomas 2010, p. 85.〕
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 increase performance, but it made little difference.〔Ethell 1995, p. 213.〕 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.〔Boer 2006, p. 83.〕
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,〔 the F2A-3 was derided by USMC pilots as a "flying coffin."〔Theodore, Taylor. ''The Battle Off Midway Island''. New York: Avon, 1982. ISBN 0-380-78790-3.〕 However the F2A-3s performance was substantially inferior〔 to the F2A-2 variant used by the Navy before the outbreak of the war despite detail improvements.
