Sea Launch is a spacecraft launch service that uses a mobile sea platform for equatorial launches of commercial payloads on specialized Zenit 3SL rockets. It has assembled and launched thirty-one rockets, with two failures and one partial failure.
The sea-based launch system means the rockets can be fired from the optimum position on Earth's surface, considerably increasing payload capacity and reducing launch costs compared to land-based systems.
Sea Launch was established in 1995 as a consortium of four companies from Norway, Russia, Ukraine and the United States, managed by Boeing with participation from the other shareholders. The first rocket was launched in March 1999.
All commercial payloads have been communications satellites intended for geostationary transfer orbit with such customers as EchoStar, DirecTV, XM Satellite Radio, and PanAmSat.
The launcher and its payload are assembled on a purpose-built ship Sea Launch Commander in Long Beach, California, USA. It is then positioned on top of the self-propelled platform Ocean Odyssey and moved to the equatorial Pacific Ocean for launch, with the Sea Launch Commander serving as command center.
In June 2009 the provider of the Sea Launch service, Sea Launch Co. LLC, filed for Chapter 11 bankruptcy protection. Sea Launch emerged from bankruptcy effective October 27, 2010. Energia Overseas Limited, a Russian corporation, is majority owner of the reorganized entity.

Famous quotes containing the words sea and/or launch:
“And then the man whom Sorrow named his friend
Cried out, Dim sea, hear my most piteous story!
The sea swept on and cried her old cry still,
Rolling along in dreams from hill to hill.
He fled the persecution of her glory....”
—William Butler Yeats (1865–1939)
“I had often stood on the banks of the Concord, watching the lapse of the current, an emblem of all progress, following the same law with the system, with time, and all that is made ... and at last I resolved to launch myself on its bosom and float whither it would bear me.”
—Henry David Thoreau (1817–1862)
