Yakovlev Yak-9

The Yakovlev Yak-9 is a Soviet single-engine fighter aircraft built by the Yakovlev design bureau, entering Soviet Air Force service in 1942 and produced in greater numbers than any other Soviet fighter of the Second World War, becoming the most common Soviet fighter type on the Eastern Front by the war's later years. Built as a refined and lightened development of the earlier Yak-7, using a mixed wood and metal structure that let Soviet industry produce it in very large numbers despite wartime aluminum shortages, the Yak-9 was built in several specialized variants, including long-range escort fighters carrying additional fuel and dedicated anti-tank variants carrying a large-caliber cannon for use against German armored vehicles. The Yak-9's combination of good performance, structural simplicity suited to mass wartime production and tactical flexibility across its variants made it one of the most significant Soviet fighter contributions to the Eastern Front air war.
