Soyuz is a family of Soviet and later Russian expendable medium-lift launch vehicles initially developed by the OKB-1 design bureau and manufactured by the Progress Rocket Space Centre factory in Samara, Russia. It holds the record for the most launches in the history of spaceflight. Soyuz rockets are part of the R-7 rocket family, which evolved from the R-7 Semyorka, the world's first intercontinental ballistic missile.
