  • Zenit Zenit was to be a modular new generation medium Soviet launch vehicle, replacing the various ICBM-derived launch vehicles in use since the 1960's (Tsiklon and Soyuz). A version of the first stage was used as strap-ons for the cancelled Energia heavy booster. But it was built by Yuzhnoye in the Ukraine; when the Soviet Union broke up planned large-scale production for the Soviet military was abandoned (Angara development was begun as an indigenous alternative). Launch pads were completed only at Baikonur; those at Plesetsk were never finished and are planned to be completed as Angara pads. However the vehicle found new life as a commercial launch vehicle, launched from a sea platform by an American/Ukrainian consortium. More...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
