The Mikoyan-Gurevich MiG-15 (NATO reporting name: Fagot) is a jet fighter aircraft developed by Mikoyan-Gurevich for the Soviet Union. The MiG-15 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.
