Yakovlev Yak-9

The Yakovlev Yak-9 (Russian: Яковлев Як-9) is a single-engine, single-seat multipurpose fighter aircraft. It was used by the Soviet Union and its allies during World War II and the early Cold War. The Yak-9 played a major role in taking back air superiority from the Luftwaffe's new Focke-Wulf Fw 190 and Messerschmitt Bf 109G fighters during the Battle of Kursk in summer 1943. It was one of the most produced Soviet fighters of World War II. The Yak-9 stayed in production from 1942 to 1948, with 16,769 built (14,579 during the war).[2] After World War II, the Yak-9 would also be used by the North Korean Air Force during the Korean War.[3]
