The name Yakovlev is used commonly in the West, but in Russia it is always abbreviated as Yak as a part of an aircraft name. The bureau was formed in 1934 under designer Alexander Sergeyevich Yakovlev.
The Yakovlev Yak-9 was a single-engine fighter aircraft used by the Soviet Union in World War II and after. A lighter development of the Yak-7 with the same armament, it arrived at the front at the end of 1942. The Yak-9 had a lowered rear fuselage decking and all-around vision canopy. Its lighter airframe gave the new fighter a flexibility that previous models had lacked. The Yak-9 was the most mass-produced Soviet fighter of all time. It remained in production from 1942 to 1948, with 16,769 built. Following World War II it was used by the North Korean Air Force during the Korean War. -wiki
