This is a captured P-51D Mustang HISTORY The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The commission approached NAA to build Curtiss P-40 fighters and the newer P-46 under license for the Royal Air Force (RAF). Rather than build an old design from another company, NAA proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October.[5] The Mustang was designed to use the Allison V-1710 engine without an export-sensitive turbosupercharger[6] or a multi-stage supercharger, resulting in limited high-altitude performance. The aircraft was first flown operationally and very successfully by the RAF and as a tactical-reconnaissance aircraft and fighter-bomber (Mustang Mk I). In mid 1942, Rolls Royce replaced the Allison with a Rolls-Royce Merlin 65, two-stage intercooled supercharged engine, resulting in a series of development aircraft known as the Mustang X. During testing at Hucknall , it quickly became clear that this dramatically improved the aircraft's performance at altitudes above 15,000 ft (4,600 m) (without sacrificing range).[7] Following receipt of the test results and after further flights by a number of USAAF pilots, the results were so positive that North American began work on converting several aircraft and these were developed into the P-51B/C (Mustang Mk III) model, which became the first long range fighter to be able to compete with the Luftwaffe's fighters.[8] The definitive version, the P-51D, was powered by the Pac
