Based on the two-seat Corsair reconnaissance biplane, the Vought V-80 was purchased by Peru (shown) and Argentina.
Among 1933 single-seater fighter variants of the Corsair were: V-80F with twin Colt MG-40s, 675 h.p. Hornet SD in N.A.C.A. cowling, and 150-gal. tankage; V-80P with Townend ring and unspatted wheels, for Peru; V-85G (similar to V-80F) for Germany. Series was adaptable as single-float seaplane.

Flown in 1933, the Vought XF3U-1 met a US Navy requirement for a two-seat fighter that was abandoned after prototype evaluation.

VL PYORREMYRSKY. The supply of fighters by Germany to the Finnish Air Force in 1945 had to be suspended because of the worsening position of production for the Luftwaffe. To safeguard against this eventuality, the Finnish Air Force laid down a specification for a single-seat interceptor fighter which would be powered by the German 1,475-h.p. Daimler-Benz DB 605 AC 12-cylinder inverted-Vee inline motor. The design was to use wooden construction in order to conserve vital metal supplies. The result was the trim-looking VL Pyorremyrsky (Whirlwind) which was first flown in 1945. Only one prototype was completed when the final truce with the Russians was concluded. Two cannon, one in each wing, were fitted. The Pyorremyrsky was designed and built by VL-Valtion Metallitehtaat, Lentokonetehaat - the State Metal Works, Aircraft Factories. The roundels are white, blue and white.

Design of the VL Pyorremyrsky, of which this was the only example, was clearly influenced by the Bf 109.

For service ashore, the Vought FU-1 could be fitted with a wheeled undercarriage, but it served primarily as a floatplane aboard US battleships.

Protracted development prevented the Vought XF2U-1 from competing for the US Navy requirement for which it was designed.
