Dahlgren, is located in Dahlgren, Virginia, with a geographically separated command, "Combat Direction Systems Activity Dam Neck" (CDSADN), located in Virginia Beach, VA, 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). The 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.
Document 10: Sea Jet: Sea Jet, or Advanced Electric Ship Demonstrator (AESD), is a naval testbed funded by the U.S. Navy's Office of Naval Research. The 133 ft vessel is operated out of the Carderock Division's Acoustic Research Detachment in Bayview, Idaho. "Sea Jet" was operated on Lake Pend Oreille, where she was used for test and demonstration of various technologies. Among the first technologies tested was an underwater discharge water jet from Rolls-Royce Naval Marine, Inc., called AWJ-21, a propulsion concept with the goals of providing increased propulsive efficiency, reduced acoustic signature, and improved maneuverability over previous Destroyer Class combatants.
Document 11: AN/SQQ-32 Mine-hunting sonar: The AN/SQQ-32 Minehunting Sonar Set (MSS) is a variable-depth mine-hunting sonar system originally developed by Raytheon and Thales Underwater Systems (formerly Thomson Marconi Sonar) for the United States Navy. It includes two separate active sonar systems to detect and classify mine-like objects on the surface, in the volume, or on the bottom of the sea. The sonar systems are packaged in a single towed body tethered to the ship through a cable providing power and data transmission, with the cable length variable via an electric winch. A hole in the ship extending from the Sonar Maintenance Room (SMR) to the hull allows movement of the towed body in different configurations for maintenance, stowage at sea, and minehunting operations. The towed body can be configured for minehunting by either locking to the bottom of the ship’s hull for shallow water operations, or by extending and retracting the tow cable to allow for variable depth sonar (VDS) operations. VDS operations are necessary in deep water due to refraction of the sonar from the various temperature layers present in the ocean; with the sonar positioned in the same thermal layer as the suspected mines the error induced by refraction is minimized. The detect and classify sonar subsystems are independently monitored and controlled by two operators at independent panels working together to find and characterize underwater objects as mine or non-mine like objects.
Document 12: Arrow-class patrol boat: The Arrow class is a series of fast patrol/assault speed boat constructed by the Sri Lanka Navy for use by its littoral warfare units, the elite Special Boat Squadron (SBS) and the Rapid Action Boat Squadron (RABS).
