Chance Vought F4U Corsair was an US fighter aircraft that entered service primarily in WWII and the Korean War. Demand for the aircraft soon overwhelmed Vought's manufacturing capability, resulting in production by Goodyear.
F8F Bearcat was the last of Grumman's piston-engine carrier-based fighters. Two XF8F-1 prototypes were ordered in November 1943, and the first of these was flown on 21 August 1944. Grumman decided once again to use the most powerful engine available at the moment.
Wildcat was the main shipboard fighter when the US entered WWII. The F4F was barrel-shaped, with angular wingtips and rudder and a narrow-track undercarriage. The F4F was well-armed and reliable, and was a natural shipboard aircraft, probably more easier to land on a carrier deck than on land.
