The Vultee P-66 Vanguard was an accidental addition to the USAAF's inventory of fighter aircraft. It was initially ordered by Sweden but by the time the aircraft were ready for delivery in 1941 the United States would not allow them to be exported designating them as P-66s and retaining them for defensive and training purposes. Eventually a large number were sent to China where they were pressed into service as combat aircraft with indifferent results.
