First flown in 1999, it has been launched 36 times, with three failures and one partial failure. It is a member of the Zenit family of rockets, and is built by the Yuzhnoye Design Bureau. RKK Energia produces the Block DM-SL upper stage, whilst the payload fairing is produced by Boeing. Launches are conducted from the Ocean Odyssey platform anchored on the equator in the Pacific Ocean, at a point with 154°W longitude, about 370 kilometres east of Kiritimati.The Zenit-3SL design began in the late 1980s as the Zenit-3, a proposed replacement for the Proton-K, which would have used a Zenit-2 rocket with a Block D upper stage. This proposal was shelved after the dissolution of the Soviet Union, as Russia inherited the space programme, however the Zenit was manufactured in Ukraine. Boeing became involved in the programme in 1994. The design was subsequently modified, with a modified version of the Block DM replacing the Block D.Sea Launch integrates the rockets in California, and transfers them to Odyssey via the Sea Launch Commander for transportation to the launch site. Once at the launch site, the rocket is erected on the platform, and a three-day countdown is initiated. The countdown is fully automated, and personnel are evacuated from the launch platform to Commander prior to launch.Zenit-3SL launches predominantly carry communications satellites into geosynchronous transfer orbits. As of 2009, the only payload to be launched by a Zenit-3SL that was not a communications satellite was a DemoSat, on the maiden flight. The only launch to be conducted to an orbit other than GTO was that of ICO F-1, which was intended to be placed into medium Earth orbit, however the rocket failed to reach orbit."@en }
