The Mustang was an American long-range, single-seat fighter and fighter-bomber used during WWII, the Korean War and other conflicts.
Built by North American Aviation in 1940 it was first flown operationally by the RAF as a tactical-reconnaissance aircraft and fighter-bomber. It was powered by the Packard V-1650-7, a license-built version of the Rolls-Royce Merlin 60 series two-stage two-speed supercharged engine, and armed with six .50 caliber (12.7 mm) M2 Browning machine guns.
The P-51 was also in service with Allied air forces in the North African, Mediterranean and Italian theatres, and saw limited service against the Japanese in the Pacific War. During WWII, Mustang pilots claimed 4,950 enemy aircraft shot down.
