The Vought F4U Corsair is an American fighter aircraft that saw service primarily in World War II and the Korean War. Designed and initially manufactured by Chance Vought, the Corsair was soon in great demand; additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A.

The United States Navy donated an F4U-1D to the National Air and Space Museum in September 1960. Vought delivered this Corsair, Bureau of Aeronautics serial number 50375, to the Navy on April 26, 1944.

F4U-1D/FG-1D/F3A-1D (Corsair Mk IV and Mk III) – Ground attack and fighter version, developed and built in parallel to the F4U-1C. It had the new engine fitted in the F4U-1A, yielding speeds of up to 684 km/h (417 mph).

The F4U-1D, introduced since the start of the Open Beta Test prior to Update 1.27, does not have many external differences from the F4U-1A. Despite the more powerful engine, the F4U-1D actually has lower maximum speed in comparison to its predecessor due to additional drags from its modifications.

The F4U-1D was the first fighter-bomber version, with racks for 2 1000 lb (454 kg) bombs or eight rockets and a 160 gallon (606 liter) drop tank. It also replaced the birdcage canopy with a bubble canopy, which greatly improved visibility.
