Volga, GRAU index 14S46, also designated 141KS, is a rocket upper stage designed in Russia. It is used with the Soyuz-2.1a and Soyuz-2-1v rockets to insert payloads into Sun-synchronous orbit. It is derived from the propulsion module of the Yantar spy satellites. [4] It is closely related to the retired Ikar upper stage. [3]
