context_page_description: 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 design team headed by James Kindelberger of North American Aviation in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force. Rather than build an old design from another company, North American Aviation 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.
  The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the Royal Air Force as a tactical-reconnaissance aircraft and fighter-bomber.
context_section_description: After World War II, the P-51 Mustang served in the air arms of more than 25 nations. During the war, a Mustang cost about $51,000, while many hundreds were sold postwar for the nominal price of one dollar to signatories of the Inter-American Treaty of Reciprocal Assistance, ratified in Rio de Janeiro in 1947.
  These countries used the P-51 Mustang:
   Australia
  In November 1944, 3 Squadron RAAF became the first Royal Australian Air Force unit to use Mustangs. At the time of its conversion from the P-40 to the Mustang, the squadron was based in Italy with the RAF's First Tactical Air Force.
  3 Squadron was renumbered 4 Squadron after returning to Australia from Italy, and converted to P-51Ds. Several other Australian or Pacific-based squadrons converted to either CAC-built Mustangs or to imported P-51Ks from July 1945, having been equipped with P-40s or Boomerangs for wartime service; these units were: 76, 77, 82, 83, 84 and 86 Squadrons. Only 17 Mustangs reached the RAAF's First Tactical Air Force front-line squadrons by the time World War II ended in August 1945.
  76, 77 and 82 Squadrons were formed into 81 Fighter Wing of the British Commonwealth Air Force, which was part of the British Commonwealth Occupation Force stationed in Japan from February 1946. 77 Squadron used its P-51s extensively during the first months of the Korean War, before converting to Gloster Meteor jets.
  Five reserve units from the Citizen Air Force also operated Mustangs. 21 "City of Melbourne" Squadron, based in the state of Victoria; 22 "City of Sydney" Squadron, based in New South Wales; 23 "City of Brisbane" Squadron, based in Queensland; 24 "City of Adelaide" Squadron, based in South Australia; and 25 "City of Perth" Squadron, based in Western Australia; all of these units were equipped with CAC Mustangs, rather than P-51D or Ks. The last Mustangs were retired from these units in 1960 when CAF units adopted a nonflying role.
   Bolivia
  Nine Cavalier F-51D (including the two TF-51s) were given to Bolivia, under a program called Peace Condor.
   Canada
  Canada had five squadrons equipped with Mustangs during World War II. RCAF 400, 414, and 430 squadrons flew Mustang Mk Is (1942–1944) and 441 and 442 Squadrons flew Mustang Mk IIIs and IVAs in 1945. Postwar, a total of 150 Mustang P-51Ds was purchased and served in two regular (416 "Lynx" and 417 "City of Windsor") and six auxiliary fighter squadrons (402 "City of Winnipeg", 403 "City of Calgary", 420 "City of London", 424 "City of Hamilton", 442 "City of Vancouver" and 443 "City of New Westminster"). The Mustangs were declared obsolete in 1956, but a number of special-duty versions served on into the early 1960s.
   China
  The Chinese Nationalist Air Force obtained the P-51 during the late Sino-Japanese War to fight against the Japanese. After the war, Chiang Kai-shek's Nationalist government used the planes against insurgent Communist forces. The Nationalists retreated to Taiwan in 1949. Pilots supporting Chiang brought most of the Mustangs with them, where the aircraft became part of the island's defense arsenal.
   People's Republic of China
  The Communist Chinese captured 39 P-51s from the Nationalists while they were retreating to Taiwan.
   Costa Rica
  The Costa Rica Air Force flew four P-51Ds from 1955 to 1964.
   Cuba
  In November 1958, three US-registered civilian P-51D Mustangs were illegally flown separately from Miami to Cuba, on delivery to the rebel forces of the 26th of July Movement, then headed by Fidel Castro during the Cuban Revolution. One of the Mustangs was damaged during delivery and none of them was used operationally. After the success of the revolution in January 1959, with other rebel aircraft plus those of the existing Cuban government forces, they were adopted into the Fuerza Aérea Revolucionaria. Due to increasing U.S. restrictions and lack of spares and maintenance experience, they never achieved operational status. At the time of the Bay of Pigs invasion, the two intact Mustangs were already effectively grounded at Campo Columbia and at Santiago. After the failed invasion, they were
