The MiG-15 (Russian: Микоян и Гуревич МиГ-15; USAF/DoD designation: Type 14; NATO reporting name: Fagot) was one of the first successful jet fighters to incorporate swept wings to achieve high transonic speeds. In combat over Korea, it outclassed straight-winged jet day fighters, which were largely relegated to ground-attack roles, and was quickly countered by the similar American swept-wing North American F-86 Sabre. The MiG-15 is believed to have been one of the most produced jet aircraft; in excess of 13,000 were manufactured. Licensed foreign production may have raised the production total to almost 18,000. The MiG-15 remains in service with the Korean People's Army Air Force as an advanced trainer. For an extensive history of the desugn and development, and the 21 variants, click here.
