The Mikoyan-Gurevich MiG-15 (Russian: Микоян и Гуревич МиГ-15; USAF/DoD designation: Type 14; 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 aerial combat during the Korean War, it outclassed straight-winged jet day fighters, which were largely relegated to ground-attack roles. In response to the MiG-15’s appearance and in order to counter it, the United States Air Force rushed the North American F-86 Sabre to Korea in many fights over "MiG Alley".
The MiG-15 is believed to have been one of the most produced jet aircraft with more than 13,000 manufactured.
The MiG-15 remains in limited service with the Korean People's Army Air Force as an advanced trainer, but they are in bad shape due to the lack of nessasery spare parts and expertise needed to keep them going.
