Sea launch

In 2016, S7 Group declared signing of the contract with Sea Launch Group of companies, providing purchase of complex "Sea Launch". Subjects of the transaction was Sea Launch Commander ship, “Odyssey” platform with the equipment of rocket segment installed on them, the land equipment in Home Port (Long Beach, USA) and all intellectual rights belonging to Sea Launch company including the trademark. Today S7 Space plans to provide 70 commercial launches within 15 years. The company has signed the cooperation agreement with RSC “Energia” directed to renewal of Sea Launch complex operation.

The program of the launch of launch vehicles "Zenit-3SL" (of the “Zenit” type) by the international consortium on operation of “Sea Launch” spaceport. The launch point settles down on the water area of the Pacific Ocean (its coordinates are 0 °00 ′ NL 154 °00 ′ WL and it’s located near Christmas Island).

“Sea Launch” project was developed in the early 90's when plans for the launching of commercial satellites assumed a global scale. The idea was to create a buoyant space-rocket complex, which unique characteristics would guarantee to satellite operators some numerous advantages (including significant increase in payload’s mass).  It could become real thanks to the launches of spacecrafts from the equatorial waters of the Pacific Ocean (a zone of the most favorable conditions for the launches) and thanks to delivery of launch vehicles to the Equator by sea. 

Technical capacity of the leading enterprises of space-rocket branch, such as American “Boeing”, the Russian RSC “Energia”, the Norwegian ship-building enterprise “Kvaerner” (nowadays “Aker Solutions”) and the Ukrainian “Yuzhnoye” and “Yuzhmash” was attracted to creation of such unique space-rocket complex. These enterprises became the Founders of ‘Sea Launch’ project that officially started in 1995.

By March, 1998 construction of special Home Port in the USA (California, Long Beach) and also construction of the mobile launch platform “ODYSSEY” and the assembly and command ship "SEA LAUNCH COMMANDER" came to the end.

By 2014 according to ‘Sea Launch’ program more than 30 successful launches of spacecrafts (including launch vehicles with heavy payloads) were made; more than 150 000 kilograms of the payload were sent on Orbit. Within the Project enormous experience (of rendering high-quality services in all cycle of preparatory and commissioning work, in the organization and carrying out all necessary operations with the spacecraft, including delivery, transportation, tests, integration and launch) was gained.

For a number of reasons in 2014 the launch activity of "Sea Launch" were paused. Until 2016, negotiations on sale of the project were conducted and measures for settlement of legal and material issues were taken. In September of the same year, “S7 group of companies” became the owner of "Sea Launch" space-rocket complex.

“S7 Space” company will carry out the launch activity of a complex. Despite sale of the project, RSC “Energia” will save the involvement in "Sea Launch" according to the agreements adopted with “S7 Space”. “Roskosmos” and “Yuzhmash” will also become “S7 Space” partners on the tasks of "Sea Launch" space-rocket complex’ launch activity. Project management will be performed from Moscow; nevertheless, for successful guiding of the international business “S7” organized “S7 Sea Launch Limited” company in the USA.

For decision of the tasks on restoration of “Sea Launch” space-rocket complex’ launch activity and its "degreasing" “S7 Space” company organized the constant headquarters in Home Port (Long Beach). By the last estimates of monitoring group, the complex is already ready for operation, and the beginning of launch activity is planned for 2018.
