Vought O2U-1 Corsair: The Vought O2U-1 was the first Vought airplane to carry the name Corsair. The O2U was built as an observation aircraft for the Navy, and the example flown by the NACA for evaluation and cowling tests was one of the last O2U-1s built. This Corsair came from the Naval Reserve squadron at Naval Air Station Anacostia, Washington, D. C.
