The P-66 Vanguard was an American single-engine fighter designed and developed by Vultee Aircraft. Not only was it manufactured in a limited number (147), but also saw limited combat action during World War II, in China, asigned to the Chinese 3rd and 5th Combat Groups until it was replaced by Curtiss P-40 Warhawk aircraft. Although it was slightly faster than the A6M Zero and the Nakajima Ki-44, the Vanguard was not as maneuverable as these Japanese fighters.
