Barry (DD 933) - Naval Cruise Book

-«l I BARRY III POST CONVL, BARRY III During this period BARRY was equipped with the latest modifications to her long range sonar, and employs this accurate sensor with an underwater battery fire control computer - one of the most sophisticated of its kind. This computer directs the fire of the Anti-Submarine Rocket System (ASROC) located aft, and the dual triple torpedo mounts forward. Another advance which was added somewhat later is the IVDS or Independent Variable Depth Sonar which enables BARRY to track submarines which attempt to hide under temperature layers at variable depths. An enlarged communications center and Combat Information Center were also included in the conversion. These modifications give BARRY one of the most advanced AntiSubmarine Warfare systems in the Navy. A secondary mission of the BARRY is to provide shore bombardment in support of Amphibious assault and ground forces. Her two rapid-fire 5 " /54 guns, mounted forward and aft, provide an effective deterrent to modern aircraft and surface targets. BARRY is 420 feet long with a maximum beam of 45 feet. Fully loaded she displaces 4000 tons with a navigational draft of 20 feet. She is designed to travel at extended periods at speeds over 30 knots. Her main propulsion plant consists of four high-pressure boilers (1200 lbs PSD and two main engines driving twin four bladed propellers. Maximum power developed by the plant is 20000 kilowatts of power, while her evaporators will produce 24,000 gallons of fresh water daily. She accelerates and maneuvers in the best destroyer tradition while possessing superior riding characteristics. Modern air-conditioned working spaces and living compartments are provided for a crew of 300 officers and men. Complete facilities are available for a squadron commander and his staff. On this cruise, COMDESRON 10 used BARRY as his flagship.
