The Mikoyan-Gurevich MiG-15, NATO reporting name "Fagot", was one of the first truly successful swept-wing jet fighters, shock-triggering a paradigm shift in aerial warfare during the Korean War. First flown in 1947, it featured a robust 35-degree swept wing and was powered by the Klimov RD-45 engine, a Soviet reverse-engineered version of the British Rolls-Royce Nene. The MiG-15's introduction in Korea completely outclassed the straight-wing American jets like the F-80 Shooting Star, forcing the rapid deployment of the F-86 Sabre. Its combination of high-altitude performance, heavy cannon armament (two 23 mm and one 37 mm), and rugged construction made it a classic adversary and one of the most-produced jet aircraft in history.
