Sea Launch will perform five launch operations for Intelsat, the sea-going launch platform company announced.

The firms signed a multiple launch services contract for five missions on the Sea Launch system, scheduled for late 2010 through 2012.

Sea Launch has performed eight successful missions for Intelsat so far, , most recently launching the Galaxy 19 satellite Sept. 24.

The new pact represents a significant addition to the Sea Launch manifest.

"This year, Sea Launch executed two successful launch missions for Intelsat, delivering our Galaxy 18 and Galaxy 19 spacecraft into orbit, which completely refreshed the North American Galaxy fleet," said Ken Lee, Intelsat senior vice president for space systems.
