Originally designed as a fighter, the aircraft was increasingly used as a fighter-bomber from the end of 1950. This was due to the appearance of the enemy’s 2nd generation MiG-15 jet fighters. However, for such a fighter there was a lot of combat work in the Korean War. The F-80C modification differed from previous ones in the presence of an ejection seat for the pilot, a new, more advanced version of the General Electric J33-A35 engine with improved performance, as well as improved machine gun armament.
