Soyuz Scientific Production Association (Russian: Московское научно-производственное предприятие (МНПК) "Союз") is a company based in Moscow, Russia. The Moscow Soyuz Scientific Production Complex was founded by Alexander Mikulin as an experimental design bureau in 1943. Mikulin's wartime engine designs powered MiG-3 interceptors and Il-2 Shturmovik attack aircraft. Sergei Tumansky succeeded Mikulin as general director of the design bureau in 1956. As the Tumanskiy OKB, the bureau produced designs for the RD-9 (used in the MiG-19 Farmer), the RD-11/RD-13/RD-25 (used in the many variants of the MiG-21 Fishbed), the R-195 (used in the Su-25 Frogfoot), the R-15 (used in the MiG-25 Foxbat), the RU-19 auxiliary power unit, the R-27/R-29 (used in the MiG-23/27 Flogger), and the R-79 (intended as the main thrust engine in the Yak-141 Freestyle). The engines designed by MNPK Soyuz are built by the Ufa Motor-Building Corporation and other plants. More information...
