The Chance Vought F4U Corsair was a carrier-capable fighter aircraft that saw service primarily in World War II and the Korean War. Goodyear-built Corsairs were designated FG and Brewster-built aircraft F3A. The Corsair served in smaller air forces until the 1960s, following the longest production run of any piston-engined fighter in U.S. history (1942-1952). Some Japanese pilots regarded it as the most formidable American fighter of World War II. The U.S. Navy counted an 11:1 kill ratio with the F4U Corsair.
Corsairs served with the U.S. Navy, U.S. Marines, Fleet Air Arm and the Royal New Zealand Air Force, as well the French Navy Aeronavale and other services postwar. It quickly became the most capable carrier-based fighter-bomber of World War II. Demand for the aircraft soon overwhelmed Vought's manufacturing capability, resulting in production by Goodyear (as the FG-1) and Brewster (as the F3A-1). From the first prototype delivery to the U.S. Navy in 1940, to final delivery in 1953 to the French, 12,571 F4U Corsairs were manufactured by Vought, in 16 separate models. - http://en.wikipedia.org/wiki/F4U_Corsair
