Vought XF5U

Developed from the original V-173 prototype, the XF5U-1 was a larger lifting body like aircraft of all-metal construction with two 1,600 hp (1,193 kW) Pratt & Whitney R-2000 radial engines. The configuration was designed to create a low aspect ratio aircraft with low takeoff and landing speeds but high top speed. The XF5U design was promising: specifications given at the time promised great maneuverability and speeds up to 550 mph.
