Spillwater Fleet base was a naval base that was operated by the Galactic Empire during the Galactic Civil War. In 0 ABY, fifty Caldorf VII interceptor missiles were removed from the Dreadnaught-class heavy cruiser Sarissa, purportedly to be taken to the Spillwater Fleet base to be checked for malfunctions. However, the missiles never made it to the base and they were instead stolen by the forces of the alien warlord Nuso Esva.
