The XF4U-3 was an experimental aircraft, designed to test out to possibility of fitting a pair of Bierman superchargers to the engine in a F4U, in an attempt to improve its high altitude performance. Work was carried out during 1943 and 1944, with test flights in April 1944. However, the superchargers were not reliable, rarely lasting for two entire test flights without a failure. April 1944 also saw the first flights of the F4U-4, and the dash three was abandoned in favour of the more conventional dash four.

A Vought-Sikorsky F4U-1 is tested inside the NASA Full Scale Wind Tunnel to verify drag reduction recommendations. The Vought F4U-1A Corsair was among the many World War II aircraft tested in the wind tunnel. The NACA's drag reduction efforts increased speed and range and gave Allied pilots critical advantages in combat.
