At approximately 0900 EST, U.S. Navy Support Facility Dahlgren in Virginia was placed on lockdown for a “security incident”. At 1000 the lockdown was lifted with no arrests. There were unconfirmed reports of shots fired on the facility.
The United States Naval Surface Warfare Center Dahlgren Division (NSWCDD), is located in King George County, Virginia. NSWCDD was initially established 16 October 1918 as a remote extension of Maryland’s Indian Head Proving Ground used for testing naval guns. The location on the Potomac River was specifically chosen for the development of a long ballistic test range on the Potomac River, required for the testing of modern, high-powered munitions.
