Volga (GRAU index 14S46, also designated 141KS) is a rocket upper stage designed in Russia used with the Soyuz 2.1a and Soyuz 2.1v rockets. It is derived from the propulsion module of the Yantar spy satellites.[4] It is closely related to the retired Ikar upper stage.[3] It was developed as a lighter and cheaper alternative to the Fregat upper stage that is used on many Soyuz 2 missions.
