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 (298 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 planes 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.
Two prototypes were ordered in 1926 and tested by the Navy Trial Board before the first production batches were ordered. In 1927, a total of 291 O2Us were produced. The O2U-2, -3 and -4 were ordered in 1928 with minor changes. By 1930 they were being superseded by the O3U which was basically similar to the O2U-4, one variant of which was fitted with the Grumman float, and were manufactured until 1936. A total of 289 were built. Many of them had cowled engines and some had enclosed cockpits.
The 600-690 hp (448-515 kW) Pratt & Whitney R-1690-42 Hornet engine was used to power Corsairs designated SU-1 to SU-4. The change in designation reflected their role as scouts (their larger engines and heavier weight precluded their use as floatplanes, and USN examples were only used on wheels from either carrier decks or land bases). A total of 289 SU designated aircraft were built for the USN. No fewer than 141 Corsairs were still serving with the United States Navy and United States Marine Corps when the United States entered World War II in December 1941.[citation needed]
Export versions included the Corsair V-65F, V-66F and V-80F for the Argentine Navy, the V-80P for the Peruvian Air Force, and the V-85G for Germany. China purchased Corsair variants V-65C and V-92C. Brazil purchased 36 aircraft V-65B, some hydroplanes V-66B and 15 V-65F.
In March 1929, Mexico purchased 12 armed aircraft O2U-2M versions with the 400 hp (300 kW) Wasp engine to quell a military coup; Mexico then built 31 more units under licence, and called them Corsarios Azcárate O2U-4A. In 1937, Mexico purchased 10 V-99M equipped with the Pratt & Whitney R-1340-T1H-1 550 hp Wasp engine, some of them may have been sent to Spain.
China purchased the 42 export versions of O2U-1 from 1929 to 1933, and 21 export versions of O3U between 1933 and 1934 and they saw extensive bombing actions. The O2U-1 versions participated in the Central Plains War and in the January 28 Incident against Japanese targets, while the O3U versions first participated in the Battle of Pingxingguan to support the Chinese ground forces, and later against the Japanese targets in Shanghai.
Peru purchased two Vought OSUs which were designated UO-1A. Later, in 1929, 12 O2U-1 were acquired. Used first as trainers, they saw action against APRA rebels in the northern areas of the country, and against Colombian ships and aircraft during the Colombia-Peru War. None were lost due to enemy fire, but several were destroyed due to accidents. These aircraft were also used for light bombing and casualty evacuation by the U.S. Marine Corps during the U.S. intervention in Nicaragua in the late 1920s.
