The Curtiss-Wright CW-21 Demon was an American, single-seat, fighter aircraft, which was introduced in 1939. In service with the Chinese Nationalist Air Force, it saw combat action in the Far East, in missions against Japanese fighters and bombers. It was also used by the Dutch East Indies Air Force. In the United States, it was used as a trainer. Since only 61 CW-21 fighters were built, it did not have any impact on the development of the war in the Far East.
The Demon was a light weight monoplane, with low-wing, an all-metal fuselage and retractable landing gear. Designed to fulfill the role of a fighter interceptor to attack enemy bombers, the CW-21 had a high rate of climb, 23 m/s (4,500 ft/min), much higher than that of the renown F4U Corsair fighter aircraft. Its armament consisted of two .50 (12.7mm) M2 Browning machine guns and two .30 (7.62mm) M1919 Browning machine guns.
