When flown in 1940, the XF4U-1 became the first U.S. single-engine production aircraft capable of 400 mph in level flight. It was a remarkable achievement for Vought, as carrier aircraft were necessarily heavier than their land-based counterparts to withstand the rigors of deck landings.
Looking at a Corsair, the most striking feature is the inverted "gull" wing. The initial design concept for the Corsair, incorporating the then-largest available fighter engine (the Pratt & Whitney 2,000 hp / 18-cylinder R-2800 Double Wasp) with an enormous 13'4" Hamilton Standard propeller, required the bent wing to keep the landing gear reasonably short while still providing ground clearance for the propeller.
However, numerous technical problems had to be solved before the Corsair entered service. Carrier suitability was especially troublesome, leading to changes of the landing gear, tailwheel, and tailhook. Additionally, a small spoiler was added to the leading edge of the port wing to reduce adverse stall characteristics.
Because of visibilty problems on landing caused by a combination of the pilot's position with the length of the nose, Corsairs were largely barred from carrier service until the end of 1944. But Marine Corps squadrons readily took to the radical new fighter. From February 1943 onward, the "U-Bird" was increasingly the leathernecks' favorite mount, flying from Guadalcanal and ultimately other bases in the Solomon Islands. Corsairs also served well as fighter-bombers in the Central Pacific and the Philippines. Night-fighter versions were produced, equipping Navy and Marine units ashore and afloat. British units flying from carriers developed a curved approach to the carrier that allowed the Corsair pilot to maintain a view of the carrier's deck, allowing safe carrier operations. At war's end, Corsairs were ashore on Okinawa combating the Kamikazes and flying from fleet and escort carriers.
During the war, Corsair production expanded beyond Vought to include Brewster (F3A) and Goodyear (FG) models. Allied nations flying the bent-wing bird included the Royal Navy and Royal New Zealand Air Force.
The F4U-4 and -5 logged combat in Korea between 1950 and 1953 while the "dash seven" model flew with the French Navy during the same period. Corsairs flew their final combat missions during the 1969 "Football War" between Honduras and El Salvador.
The AU Corsair was a ground-attack version produced for the Korean War. The Pratt & Whitney R-2800 engine, while it was supercharged, was not as highly "blown" as on the F4U.
