LP Odyssey is a self-propelled semi-submersible mobile spacecraft launch platform converted from a mobile drilling rig in 1997.

The vessel was used by Sea Launch for equatorial Pacific Ocean launches. She works in concert with the assembly and control ship Sea Launch Commander. Her home port was at the Port of Long Beach in the United States.

In her current form, Odyssey is 436 feet (133 m) long and about 220 feet (67 m) wide, with an empty draft displacement of 30,000 tonnes (29,500 long tons), and a submerged draft displacement of 50,600 tonnes (49,800 long tons).^[2] The vessel has accommodations for 68 crew and launch system personnel, including living, dining, medical and recreation facilities. A large environmentally-controlled hangar stores the rocket during transit, from which the rocket is rolled out and erected prior to fueling and launch.

In September 2016 the platform along with other Sea Launch assets was sold to S7 Group, the parent company of S7 Airlines.^{[3][needs update]} Since then she has been moved to a port on the east coast of Russia, along with the other ship.
