Launch System

Home Port Segment



The Sea Launch Home Port complex provides the facilities, equipment, supplies, personnel, and procedures necessary to receive, transport, process, test, and integrate the spacecraft and its associated support equipment with the Sea Launch system.

Home Port is a seventeen acre site located in Long Beach, California, USA. The secure facility has a main gate that is staffed twenty-four hours a day, seven days a week. Situated just south of Los Angeles, California, USA the complex is within the boundaries of the Port of Long Beach and is at the eastern end of the former Navy mole that partially forms the Long Beach harbor. Proximity to international airports such as Los Angeles International (forty kilometers away) provides easy access for customers and offers inherent advantages in transportation costs and risk avoidance. The Home Port also serves as the base of operations for both of the Sea Launch vessels. The personnel providing the day-to-day support and service during pre-launch processing and launch are located at the Home Port. 

The Sea Launch facility provides a customer office area, separate from the spacecraft provider office area, that will either accommodate six customer employees and a separate conference room with a seating capacity of fifteen, or an office area for up to ten employees and use of a shared conference room with the spacecraft manufacturer. This office area also provides twelve Internet and international capable telephone connections. Sea Launch can provide photocopier, telephone, and fax capability, and will provide office supplies in support of customer requirements. Sea Launch cannot provide personal computers but will provide technical support for routine computer problems. Sea Launch can arrange for and support connection of international leased data circuits. 

Sea Launch can provide paging capability for up to six persons, and local cellular phone capability to the spacecraft owner-operator for up to three persons. Sea Launch can assist in identifying such services as secretarial and translation services and can support the office requirements associated with these services.

Sea Launch security will provide a secure office access system unique to the spacecraft owner-operator. Sea Launch Security will coordinate all specific requirements with the customer and provide support when and where required. 

Launch operations begin at Home Port in Long Beach, Calif., where the satellite is received. Following the fueling and encapsulation of the satellite in our state-of-the-art payload processing facility, the integrated payload unit is transferred to the Assembly and Command Ship for integration with the launch vehicle.

While at Home Port, the horizontally integrated rocket is transferred to the Launch Platform Odyssey, where it is stored in an environmentally controlled hangar during transit to the equator.


Customer spacecraft are processed in the specially designed Payload Processing Facility (PPF). Here, the payload, is loaded with fuels, encapsulated within a payload fairing and prepared for mating with the Sea Launch Zenit-3SL rocket.

The PPF provides two parallel cells for spacecraft testing and fueling operations and a separate encapsulation cell. All processing/fueling cells have backup emergency power and an uninterrupted power supply. If required, satellite standalone processing can be conducted twenty-four hours a day, seven days a week. Sea Launch logistics can assist in arranging calibration and measuring equipment services.

There are remote control rooms, with closed circuit television, adjacent to the customer offices for monitoring operations in the PPF.

The spacecraft provider office and remote control facilities are equipped with closed circuit television enabling observation of fueling and encapsulation operations. Additional information is provided in the Sea Launch Facilities Handbook

Once the satellite has been thoroughly checked out by customer technicians, the encapsulated payload is rolled out to the ACS and integrated with the launch vehicle. Vehicle and spacecraft segments are mated with the launch vehicle in a horizontal orientation. The fully integrated launch vehicle is then transferred by an on-board crane system from the ACS to the Launch Platform Odyssey.
