Portions of the Charleston, South Carolina metropolitan area (The City of Charleston, The City of North Charleston, The City of Goose Creek, and The City of Hanahan) are home to all branches of the United States Military. During the Cold War, the Naval Base (1902-1996) became the third largest U.S. homeport serving over 80 ships and submarines. In addition, the Charleston Naval Shipyard repaired frigates, destroyers, cruisers, sub tenders, and submarines. Also, the Shipyard was responsible for refueling nuclear subs.

During this period, the Weapons Station was the Atlantic Fleet's load out base for all nuclear ballistic missile submarines. Two SSBN "Boomer" squadrons and a sub tender were homeported at the Weapons Station, while one SSN attack squadron, Submarine Squadron 4, and a sub tender were homeported at the Naval Base. At the 1996 closure of the Station's Polaris Missile Facility Atlantic (POMFLANT), over 2,500 nuclear warheads and their UGM-27 Polaris, UGM-73 Poseidon, and UGM-96 Trident I delivery missiles (SLBM) were stored and maintained, guarded by a U.S. Marine Corps Security Force Company.

In 2010, the Air Force Base (3,877 acres) and Naval Weapons Station (>17,000 acres) merged to form Joint Base Charleston. Today, Joint Base Charleston, encompassing over 20,877 acres and supporting 53 Military Commands and Federal Agencies, provides service to over 79,000 Airmen, Sailors, Soldiers, Marines, Coast Guardsmen, DOD civilians, dependents, and retirees.
