A space shuttle is a reusable spacecraft built before the Great War. There is one located in the ruins of San Francisco in Fallout 2, though it lacks either rocket boosters or an external fuel tank; a quest involves finding fuel for it. The Enclave may have planned to use one or more shuttles to leave Earth and colonize other planets, but it seems likely that most were destroyed in the Great War or succumbed to neglect in the years that followed.
