P-51 Mustang

Sep 29, 2011 No Comments by

The North American Aviation P-51 Mustang was an American long-range, single-seat fighter and fighter-bomber used during World War II, the Korean War and in several other conflicts. During World War II Mustang pilots claimed 4,950 enemy aircraft shot down, the most of any Allied fighter.

It was conceived, designed and built by North American Aviation (NAA), under the direction of lead engineer Edgar Schmued, in response to a specification issued directly to NAA by the British Purchasing Commission; the prototype NA-73X airframe was rolled out, although without an engine, 102 days after the contract was signed.[2] The Mustang was originally designed to use a low-altitude rated Allison V-1710 engine, and was first flown operationally by the Royal Air Force (RAF) as a tactical-reconnaissance aircraft and fighter-bomber. The definitive version, the P-51D, was powered by the Packard V-1650-7, a licence-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.

From late 1943, P-51Bs (supplemented by P-51Ds from mid-1944) were used by the USAAF’s Eighth Air Force to escort bombers in raids over Germany, while the RAF’s 2 TAF and the USAAF’s Ninth Air Force used the Merlin-powered Mustangs as fighter-bombers, roles in which the Mustang helped ensure Allied air superiority in 1944.[3] 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.

At the start of Korean War the Mustang was the main fighter used by the United Nations. However, jet fighters, including the F-86, took over this role, and the Mustang became a specialised ground-attack fighter-bomber.

Despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After World War II and the Korean War, many Mustangs were converted for civilian use, especially air racing.
