John A. Dahlgren in the context of "Ulric Dahlgren"

The United States Naval Surface Warfare Center Dahlgren Division (NSWCDD), named for Rear Admiral John A. Dahlgren, is located in King George County, Virginia, in close proximity to the largest fleet concentration area in the Navy. NSWCDD is part of the Naval Surface Warfare Centers under the Naval Sea Systems Command (NAVSEA). NSWCDD was initially established 16 October 1918 as a remote extension of Maryland's Indian Head Proving Ground used for testing naval guns. The Dahlgren site was named the Lower Station, Dahlgren Naval Proving Ground when it first opened. 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.

The NSWCDD employs approximately 4,700 scientists, engineers and support personnel at the Dahlgren organization and more than 350 at NSWCDD DNA. Prior to 2007, Panama City Coastal Systems Station located at the Naval Support Activity Panama City was part of Dahlgren Division, but in 2008, it became its own division within the NAVSEA Naval Surface Warfare Center structure.
