The MiG-15 was a Soviet jet fighter known for its swept wings and transonic speeds. It dominated straight-winged jets during the Korean War, forcing the US to deploy the F-86 Sabre. The MiG-15's design influenced later Soviet jets like the MiG-17 which remained effective even against supersonic fighters in the Vietnam War. The MiG-15 was one of the most produced jet aircraft and is still used for training in North Korea.
