# Naval Support Activity Charleston

Naval Support Activity Charleston, originally designated Naval Weapons Station Charleston, is a base of the United States Navy located on the west bank of the Cooper River, in the cities of Goose Creek and Hanahan South Carolina. The base encompasses more than 17,000 acres (69 km$^2$) of land with 10,000 acres (40 km$^2$) of forest and wetlands, 16-plus miles of waterfront, four deep-water piers, 38.2 miles (61.5 km) of railroad and 292 miles (470 km) of road. The current workforce (military/civil service/contractor) numbers more than 11,000 with an additional 3,600 people in on-base family housing.
Of the three Naval Weapons Stations on the U.S. East Coast, the Charleston facility is the largest.
Under the 2005 Base Realignment and Closure Commission's recommendations, the Air Force is to jointly manage Naval Weapons Station Charleston and Charleston Air Force Base as Joint Base Charleston.

## History

Commissioned on November 5, 1941 as the United States Naval Ammunition Depot (NAD) consisted of 6,368 acres this is now the Station's Southside area including the Cooper River waterfront. The facility was used as an ammunition collection and distribution point during World War II. Ammunition manufactured throughout the country was sent to the base and then used to supply ordnance to Atlantic fleet vessels. Following WWII, the Depot was charged with the removal of ordnance from ships being deactivated and was used as a weapons storage site. The NAD's status changed from caretaker to inactive to maintenance to active from 1947 through 1952.
During the mid-1950s, the installation was expanded, the Northside area, another 5,219 acres, was acquired by the Navy in January 1954 and called the Naval Weapons Station Annex and charged with new duties that included the handling of guided missiles and the docking, servicing and loading of submarines. Base personnel were tasked with arming submarines with the UGM-27 Polaris missile.
In 1960 the Polaris Missile Facility Atlantic (POMFLANT) was constructed within the base to enable the handling of Terrier, Tarter, and, Hawk, missiles. Buildings were added again in 1969 for the Standard and Red Eye missiles. The base continued to grow through the 1970s, the Marrington area, an additional 2,894 acres located between Red Bank Road and Foster Creek, was added to the Station. The Navy designated the eastern half as the Marrington Plantation Outdoor Recreation Area and used the western half for the construction of MenRiv Housing and the adjacent support facilities. On September 30, 1981, the Station acquired the nearby Charleston Army Depot. The station's name was then changed to Naval Weapons Station South. In 1995 POMFLANT was decommissioned and the fleet ballistic missile operations moved to Kings Bay, Georgia.
The Naval Nuclear Power Training Command school opened in 1998 and occupies over 50 acres in the central part of the original Marrington tract.
Under the 2005 BRAC the Naval Weapons Station was combined with Charleston Air Force Base to create Joint Base Charleston.

## Current status

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 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. The Shipyard was also equipped for the refueling of nuclear subs.
During this period, the Weapons Station was the Atlantic Fleet's load out base for all "41 for Freedom" 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.
During the 1960's through the early 1990's Submarine Group Six was headquartered in Charleston. Being the largest submarine group in the U.S. Navy, and one of the largest in the world, including five submarine squadrons in three home ports with five submarine tenders, more than 50 submarines and more than 18,000 active duty members. Of which 12,000 of the active duty members were home ported in Charleston.
The Naval Support Activity expanded its mission and Department of Defense support role over time with over 40 tenant commands, and today is a training center, with the Naval Nuclear Power Training Command (NNPTC), Nuclear Power Training Unit, Propulsion Facility, and Border Patrol satellite academy; Naval Consolidated Brig, Charleston; Navy Munitions Command Unit Charleston; Explosive Ordnance Detachments; Marine Corps Reserve Center; Naval Information Warface Center Atlantic (NIWC-LANT, the largest employer in the Charleston area); 269 above-ground ammunition magazines, maintenance and storage of military ordnance including mines, and serves as an Army logistics hub, the busiest continental United States surface port in the defense transportation system. In addition, it contains more than 1,800 on-base houses for Navy enlisted and officer dependents as well as Coast Guard dependents, and has a child care facility, elementary and middle schools. A large medical clinic near NNPTC in Goose Creek was added in 2008.
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.
The former Charleston Naval Base has been transformed into a multi-use Federal Complex (231 acres) with 17 government and armed forces tenants, as well as homeport for 6 Roll-On/Roll-Off (RORO) Military Sealift Command Ships, 4 Coast Guard National Security Cutters, and 2 National Oceanic and Atmospheric Administration (NOAA) Research Ships.
NSA Charleston remains a Commander, Navy Installations Command administrative support installation assigned to Commander, Navy Region Southeast, located on the Joint Base Charleston Naval Weapons Station. NSA Charleston was reorganized as an "Embedded Military Unit" within the Joint Base Charleston 628th Air Base Wing. NSA Charleston Navy personnel are embedded into the Air Base Wing installation support squadrons to carry out their functions. After the creation of the Joint Base, the NSA Charleston Commanding Officer became the Deputy Commander of the 628th Air Base Wing, responsible to the Wing Commander for base installation support operations.
