About this Unit
Shore Intermediate Maintenance Activity (SIMA) Charleston, S.C., was established to provide essential maintenance and repair support to the U.S. Navy’s Atlantic Fleet ships stationed at the historic Charleston Naval Base. Activated during the buildup of the Cold War, SIMA Charleston played a crucial role in ensuring operational readiness by delivering technical expertise, equipment repairs, and modernization services for a wide range of vessels. Throughout its tenure, the unit supported numerous naval operations, including deployments during the Vietnam War, Cold War patrols, and fleet exercises in the Atlantic and Caribbean. SIMA Charleston's contributions were integral to the Navy’s mission until the base realignment and closure process in the 1990s led to its deactivation, marking the end of an era for Charleston’s naval maintenance community.
