Project Study Area
The study area for the JLUS includes the Counties of King George and Westmoreland in Virginia; the Town of Colonial Beach, Virginia; the Counties of Charles and St. Mary's in Maryland; and, the Naval Support Facility (NSF) Dahlgren and Pumpkin Neck Annex.
NSF Dahlgren is a United States (US) Department of the Navy (Navy) facility under the supporting command of Naval Support Activity (NSA), South Potomac, Naval District Washington. NSF Dahlgren is located 25 miles east of Fredericksburg, Virginia and 53 miles south of Washington, DC. NSF Dahlgren consists of 4,300 acres located on the Potomac River in King George County. The installation supports eight major Joint Navy and other DOD commands that account for a wide range of operational military support missions, including research, development, test, and evaluation (RDT&E) of weapon systems.
Active ranges on NSF Dahlgren are used to test and evaluate weapons systems and ordnance. The Potomac River Test Range's (PRTR) instrumentation allows evaluation of projectile speed, performance, and other parameters, a unique capability among DOD ranges. This invaluable live-fire range is located southeast of NSF Dahlgren on the Potomac River extending approximately 50 miles southward from Dahlgren to the Chesapeake Bay. Similarly, a second range, the Explosive Experimental Area (EEA) or Pumpkin Neck Annex to NSF Dahlgren, provides a unique facility for static tests of ordnance and explosives for operational military systems, as well as RDT&E for new capabilities. The EEA is located south of the base on the Potomac River.
