The Chance Vought F4U Corsair was an American fighter aircraft that saw service primarily in World War II and the Korean War.Demand for the aircraft soon overwhelmed Vought’s manufacturing capability, resulting in production by Goodyear: Goodyear-built Corsairs were designated FG. 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, in the longest production run of any piston-engined fighter in U.S. history.
