Assembly and Command Ship


Assembly and command ship (ACS) was built at a Kvaerner shipyard in Glasgow, Scotland. ACS design was developed on the basis of a Roll On/Roll Off (RO/RO) cargo vessel. The installation on the ACS of the rocket segment systems and equipment was performed at Kanonersky shipyard (St. Petersburg)

When at port, ACS serves as an assembly shop, and when at sea, it serves as a control center for the launch vehicle pre-launch processing and launch, also providing accommodations for the crew, specialists who service rocket and space hardware and control launches, and customer representatives. ACS is outfitted with systems and equipment which allow to conduct on its board integrated tests of the launch vehicle and the upper stage, fill the upper stage with high-boiling propellant components and gases, assemble and test the integrated launch vehicle. ACS houses a command station for controlling the upper stage flight, and facilities for receiving and processing telemetry measurements.

The ship can accommodate up to 240 people, placing at their disposal a conference room, a movie theater, a cafeteria, lounges, rooms for recreation and exercise, a swimming pool, and a first aid clinic.

ACS home port is Long Beach port located in south-western USA (California).

The ship arrived to the Home Port from Europe under its own power by way of Panama Canal.
