Shvetsov

Shvetsov was a Soviet design bureau founded in Perm, USSR, in 1934, to produce the Wright Cyclone-derived Shvetsov M-25. Originally headed by A.D. Shvetsov, the OKB became the primary provider of radial piston engines for Soviet aircraft industry (Mikulin's and Klimov's OKB were assigned to creation of in-line engines). After the founder's death in 1953, the OKB was taken over by Pavel Soloviev.
