History
The Yakovlev Yak-1 series design work began in the late thirties, with the first flight taking place in 1939. Production started in the same year, and by 1941, these planes were beginning to be issued to Soviet Air Force fighter squadrons. The type went through a considerable amount of development, resulting in the Yak-7, Yak-9 and later the Yak-3. At first designated I-26, the Yak-1 was later redesignated Yak-1 in honor of its designer, and during its service life was upgraded in several ways, including replacing the faired-in canopy with a version allowing the pilot to see directly behind him. Some units modified their aircraft, using what was known as the Shinkarenkov Modification, which was later incorporated into all Yak production aircraft. The Yak-1 was the first of a series of fighters that became the mainstay of the Soviet Air Force for the duration of World War II.
