Vought O2U Corsair

The Vought O2U Corsair is a 1920s biplane scout and observation aircraft. Developed by Vought Corporation, the O2U was ordered by the United States Navy (USN) in 1927. Powered by a 400 hp (300 kW) Pratt & Whitney R-1340 engine, it incorporated a steel-tube fuselage structure and a wood wing structure with fabric covering. Many were seaplanes or amphibians.
The O2U was the first of several Vought aircraft to bear the name Corsair. The Vought SBU Corsair of 1933, Vought F4U Corsair of 1938, and A-7 Corsair II of 1963 all also bore the name.
