The Vought FU was a biplane fighter aircraft of the United States Navy in service during the late 1920s.

Vought already had a two-seat observation plane, the UO-1, basically a VE-7 with additional fuselage streamlining and a Wright J-3 radial engine.

This was made into a fighter simply by covering over the front cockpit of the observation plane, mounting machine guns in that area, and upgrading to a 220 hp (160 kW) Wright R-790 Whirlwind with a supercharger.

With their float gear mounted, one was assigned to each of the battleships of the Pacific Fleet, where these observation seaplanes were launched from catapults.
