HMAS Brisbane : Gun Plot Room : Gun Plot valve unit

Valve, manually operated for a vent system of unknown purpose (probably fresh air), painted white. The valve has an oval shaped body with flanges at the bottom. One circular flange provides a connection point to a pipe and is secured by six bolts (two missing). On the opposite side of the valve is mounted a cylindrical vent with wire grating. At the top of the unit is a circular operating wheel, (painted red) with a small additional handle. On the back of the unit is written DESCO. While on the side is written DESCO 5000.54824.841350. The unit is ceiling-mounted above the right corner of the GPR work bench.

This component was removed from HMAS Brisbane after the ship was de-commissioned in 2001. The vavle is fitted in the Gun Plot Room. This unit was attached to one wall, close to the ceiling. HMAS Brisbane [II] was commissioned into the Royal Australian Navy in December 1967 and was the second vessel of that name to serve in the RAN. Known officially as DDG-41, Brisbane was the third of the RAN's American-built "Charles F. Adams" class guided-missiles destroyers. This class were the first major Australian warships designed and built in America, and were constructed by the Defoe Shipbuilding Co. The original complement of the Brisbane was 20 officers and over 300 sailors. Main armament was two 5-inch/54 calibre guns and anti-submarine torpedoes. The Ikara missile system was subsequently added. In later service the ship was known by the nick-name ‘the Steel Cat’. The HMAS Brisbane saw operational service in two conflicts. During the Vietnam War the ship undertook two tours of duty with the United States Seventh Fleet, in 1969 and again in 1971. The ship’s major task was to provide gunfire support for the land campaign. During the Gulf War (1990-91), Brisbane was one of four Australian warships to serve a tour in Gulf waters. The Brisbane arrived in the Gulf in December 1990 and operated there until March 1991, performing a number of roles. Apart from contributing to the anti-aircraft defences in the carrier screen, the ship also kept watch for mines and ensured that small civilian craft kept well away from the carrier group. Later, during Operation Desert Storm, the Brisbane controlled fighter combat air patrols and tanker aircraft. The ship’s final role was as an escort for US replenishment ships. In 2003 HMAS Brisbane was retired from service in the Royal Australian Navy. The Brisbane was the last steam powered ship in the RAN. HMAS Brisbane was sunk as a recreational dive wreck off the coast of southern Queensland in July 2005.
