NSA South Potomac serves as a vital support installation for the U.S. Navy and other Department of Defense tenants in Virginia. The base was originally established to provide logistical and administrative support to nearby naval activities, but its mission has evolved over time.
Today, NSA South Potomac encompasses a wide range of operational and research functions. The base primarily supports Naval Support Facility (NSF) Dahlgren and NSF Indian Head, which are key centers for research, development, testing, and evaluation (RDT&E) of naval warfare systems.
Major construction phases took place during World War II, when the demand for advanced weapons testing and support surged. Over the decades, the installation expanded its facilities to accommodate new technologies and the Navy’s growing needs.
During the Cold War era, the base supported critical research and development projects essential to national defense. This period saw further growth and modernization across the installation.
Significant units stationed at NSA South Potomac include the Naval Surface Warfare Center Dahlgren Division and the Naval Explosive Ordnance Disposal Technology Division at Indian Head. These units have contributed to major advances in naval weaponry and explosive ordnance disposal capabilities.
Today, NSA South Potomac functions as a regional support hub, providing security, infrastructure, and administrative services to tenant commands. The base also plays an important role in the local community by offering employment and supporting regional economic development.
The installation has consistently operated under the NSA South Potomac designation since its establishment as a regional support entity. There have been no significant official name changes throughout its history.

When you receive your PCS orders to NSA South Potomac, start by logging into the Defense Personal Property System (DPS) to schedule your move and review your entitlements. Contact your losing installation’s transportation office promptly to discuss your move options, including Household Goods (HHG) shipment or a Personally Procured Move (PPM/DITY). Both methods have specific requirements and reimbursement processes. DPS is your main portal for tracking shipments, uploading documents, and communicating with your transportation office. For moves to NSA South Potomac, most families choose HHG, but PPM may offer more flexibility if you prefer to handle your own move.
