The North American Aviation P-51 Mustang was an American long-range single-seat WWII fighter aircraft.
Designed and built in just 117 days, the Mustang first flew with the Royal Air Force (RAF), serving as a fighter-bomber and reconnaissance aircraft before conversion to a bomber escort, employed in raids over Germany, helping ensure Allied air superiority from early 1944. The P-51 was in service with Allied air forces in Europe and also saw limited service against the Empire of Japan in the Pacific War. The Mustang began the Korean War as the United Nations' main fighter, but was relegated to a ground attack role when superseded by jet fighters early in the conflict. Nevertheless, it remained with some air forces until the early 1980s.
