The Soyuz 2.1v (Russian: Союз 2.1в, Union 2.1v), GRAU index 14A15,[3] known early in development as the Soyuz-1, is a expendable Russian medium-lift launch vehicle. It is derivative of the Soyuz 2 but utilizing a single core stage (no boosters) built around the powerful NK-33 engine, 50-year-old refurbished remnants from the Soviet N1 moon rocket. It is a member of the R-7 family of rockets built by Progress in Samara. Launches have been conducted from the Plesetsk Cosmodrome in northwest Russia, and are expected to be conducted in the future from the Vostochny Cosmodrome in eastern Russia,[4] and the Baikonur Cosmodrome in Kazakhstan.[5]
