Technical parameters

The Assembly and Command Ship—or ACS—is an all-new, specially designed vessel that serves as a floating rocket assembly factory while in port, provides crew and customer accommodations and also houses mission control facilities for launches at sea. In the fall of 1997, the ship sailed for Russia, where special equipment for handling rocket components and for commanding and controlling launches was installed and tested. It arrived in Long Beach, Calif., on July 13, 1998, after a voyage through the Panama Canal.

The ACS is approximately 200m long, 32.3m wide, with a displacement of more than 30000 tonnes and has a cruising range of 33000km. The ACS provides accommodations for up to 240 crew members, customers and VIPs—including medical facilities, dining room, recreation and entertainment facilities. (Sea Launch Website, 2008)
