While this spacecraft is designed for a 15-year service life on orbit, Sea Launch’s direct insertionFact|date=May 2008 into equatorial orbit is expected to yield additional years of fuel life. Galaxy 18 was scheduled to be launched by Sea Launch on May 8, 2008 but was pushed to May 25Fact|date=May 2008. It was subsequently moved up to 21 May. The launch took place successfully at 09:43 GMT.
