When the Korean War erupted in late June 1950, the USAF"s standard fighter in the Far East was the F-80 Shooting Star. Although the F-80 mastered the North Korean Air Force, its lack of endurance resulted in the USAF rushing 145 obsolescent F-51 (nee P-51) Mustangs to Korea to serve principally in ground attack and reconnaissance roles for the USAF, the South African Air Force, the Royal Australian Air Force, and the embryonic Republic of Korea Air Force. By the time the war ended in 1953, some 194 Mustangs had been lost, most to anti-aircraft fire. These F-5 is were some of the most colorful Mustangs to ever see action, and the author has used his extensive contact base to accumulate the largest private collection of Korean War period color material in the world. Accompanying the photos are detailed captions, quotes from pilots, full appendices listing the units and F-51s that served in Korea, plus specifications, cutaways of the aircraft, and cockpit diagrams.
