In production longer than any other US fighter of World War II, the Corsair had several claims to fame.  It was credited with an 11:1 ratio of kills to losses in action against Japanese aircraft and was the last piston-engined fighter in production of any of the US services.  Its greatest attribute, though, was the excellence of its overall performance, making it certainly the finest carrier-based fighter of any used by the combatants in World War II, and perhaps the best of any US fighters in that conflict.
