Concept
Rokot
Summary
Rokot (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 into a 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 US36 million).
Rokot's total mass was 107 tonnes, its length 29 metres and its maximum diameter 2.5 metres. The liquid-fueled launch vehicle comprised three stages. The lower two were based on the Soviet UR-100N ICBM; the first stage used an RD-0233 / RD-0234 engine complex, while the second stage used an RD-0235. The third stage was a Briz-KM (Бриз-КМ meaning Breeze-KM), which has a mass of about 6 tonnes when fuelled, and is capable of flying for 7 hours and reigniting its engine six times during flight, allowing different satellites to be placed into different orbits. All stages used Unsymmetrical dimethylhydrazine (UDMH) (unsymmetrical Dimethylhydrazine) as fuel and dinitrogen tetroxide (N2O4) as oxidiser. The Strela is a similar rocket, also based on the SS-19.
The first suborbital test launch succeeded on 20 November 1990 from Baikonur Cosmodrome. On 26 December 1994, Rokot brought its first satellite into Earth orbit. In 1995, Khrunichev State Research and Production Space Center formed a company with German DaimlerBenz Aerospace to market Rokot launches for commercial use. Later, the company was renamed to Eurockot Launch Services. Eurockot bought 45 Rokots from the Russian strategic missile forces to build its inventory.
