Smolensk Aircraft Plant was founded in1926 as an aircraft repairs enterprise. In the 1930s the enterprise mastered series repairs of the R-5, RD, R-6, TB-1, and SB aircraft, as well as the M-17, M-25 and M-100 aero-engines.
In 1934 the plant took possession of a special constructions bureau -BOK. Its primary task was the development of stratospheric and extra-long-range aircraft. V.A.Chizhevsky was appointed BOK's Chief Designer.
The enterprise developed and built the BOK-1 first Soviet statospheric aircraft with a pressurized cockpit, BOK-5 "flying wing" aircraft, BOK-7 experimental high-altitude aircraft, BOK-15 record-setting circumnavigating aircraft, and nacelles for the SSSR-2 and SSSR-3 stratospheric airships.
In 1939 through 1941 the plant prepared production of the II-2 striker (it was launched after the plant was evacuated to Kuibyshev). The restoration of the plant began after liberation of Smolensk.
In the spring of 1944 the plant set going rapairs of the II-2, La-5, Yak-7 and La-7, and after the war repairs of the Yak-3, Yak-9 and Yak-11 aircraft. In subsequent years the plant mastered experimental and series production of units, unmanned aerial vehicles and rockets, developed by the design bureaus of A.I.Mikoyan, V.N.Chelomey, S.V.Ilyushin, A.S.Yakovlev, A.Ya.Bereznyak and S.A.Lavochkin.
The most important landmarks in the plant's post-war history are participation in the manufacture of the Yak-40, Yak-42, Yak-18T and Tu-154M passenger aircraft, Buran reusable orbiter system, M-55 Geophysika high-altitude aircraft, SM-92T Turbo-Finist light multipurpose aircract and manufacture of units for the Yak-130 combat trainer and Pchela UAVs. The plant participates in a number of programmes, including the production of some military products, developed by "Raduga" State Machine-Building Design Bureau.
The enterprise also manufactures consumer goods: camping folding forniture and recreation goods.
