Rokot (Russian: Рокот meaning Rumble or Boom), also transliterated Rockot, was a Soviet Union (later Russian) space launch vehicle that was capable of launching a payload of 1,950 kilograms (4,300 lb) into a 200-kilometre (120 mi) Earth orbit with 63° inclination. It was based on the UR-100N (SS-19 Stiletto) intercontinental ballistic missile (ICBM), supplied and operated by Khrunichev State Research and Production Space Center. The first launches started in the 1990s from Baikonur Cosmodrome out of a silo. Later commercial launches commenced from Plesetsk Cosmodrome using a launch ramp specially rebuilt from one for the Kosmos-3M launch vehicle. The cost of the launcher itself was about US$15 million in 1999;[6][7] The contract with European Space Agency (ESA) for launching Swarm in September 2013 was worth €27.1 million (US$36 million).[8]
