HMAS Quadrant (G11)

HMAS ''Quadrant'' (G11/D11/F01), named for the navigational instrument, was a Q-class destroyer operated by the Royal Navy as HMS ''Quadrant'' (G67/D17) during World War II, and the Royal Australian Navy (RAN) from 1945 to 1957. The ship was built during the early 1940s as one of the War Emergency Programme destroyers, and entered service in 1942.

During World War II, ''Quadrant'' served as a convoy escort in the Arctic, South Atlantic, and Indian Oceans, and operated with the British Eastern and British Pacific Fleets. At the war's end, the ship was decommissioned and transferred to the RAN, which operated her for two years before placing her in reserve. In 1950, the ship was docked for conversion into an anti-submarine frigate. ''Quadrant'' was recommissioned in 1953, and operated with the RAN until 1957, when she was paid off. The ship was sold for breaking in 1963.

Design and construction

''Quadrant'' was built to the wartime Q-class design; the third flotilla of War Emergency Programme destroyers. These ships had a displacement of 1,750 tons at standard load, and 2,388 tons at full load.Cassells, ''The Destroyers'', p. 87 The destroyer was in length overall, long between perpendiculars, and had a beam of . Propulsion was provided by two Admiralty 3-drum boilers connected to Parsons geared turbines; these provided to the destroyer's two propellers.Cassells, ''The Destroyers'', p. 88 ''Quadrant'' could reach speeds of . The ship's company consisted of 220 officers and sailors.

''Quadrant''s armament (at the end of World War II) consisted of four single 4.7-inch QF Mark XI** guns, a quadruple 2-pounder "pom-pom", six single 20 mm Oerlikon anti-aircraft guns, and two quadruple torpedo tube sets for torpedoes. The ship was also fitted with four depth charge throwers, with up to 70 depth charges carried.

The destroyer was laid down by R. and W. Hawthorn, Leslie and Company Limited at Hebburn-on-Tyne, England on 24 September 1940. She was launched on 28 February 1942 by the wife of one of the shipyard's directors. ''Quadrant'' was commissioned into the Royal Navy on 26 November 1942.

Royal Navy service

During World War II, ''Quadrant'' served with the British Eastern and British Pacific Fleets.

''Quadrant'' was engaged in convoy escort duties in the Arctic, South Atlantic, and Indian Oceans. She took part in the North African landings, aircraft carrier strikes against Surabaya and bombardment of the Nicobar Islands. She served with the British Pacific Fleet in 1945 where she took part in operations against Formosa (Taiwan), Okinawa, and the Japanese home islands.

Transfer to RAN

''Quadrant'' was loaned to the Royal Australian Navy (RAN) in exchange for the return of one of the N-class destroyers. ''Quadrant'' commissioned into the RAN on 18 October 1945, and was used to transport soldiers from New Guinea home to Australia. On 16 August 1947, the destroyer was paid off into reserve.Cassells, ''The Destroyers'', p. 89

Frigate conversion

On 15 February 1950, the heavy cruiser departed Sydney for Melbourne with ''Quadrant'' in tow. The vessels arrived at Melbourne on 18 February. Conversion of ''Quadrant'' to a fast anti-submarine frigate began at the Williamstown Naval Dockyard in Melbourne during April 1950.

During the conversion; all of ''Quadrant''s previous armament was stripped off, and replaced with two 4-inch guns, two 40 mm Bofors cannon, and two Squids (ahead throwing anti-submarine weapons). The conversion was completed in mid 1953, and the ship recommissioned into the RAN on 16 July.

RAN service

After recommissioning, ''Quadrant''s service was mainly in Australian waters. ''Quadrant'' escorted the Royal Yacht during the visit to Australia of Queen Elizabeth II and the Duke of Edinburgh in February 1954. ''Quadrant'' visited New Guinea, Manus, and New Britain in October 1954, New Zealand in March 1955, and spent a period on exercises in Far East waters in June 1955. In March 1956, she took part in exercises in Malayan waters. During June 1956 she served for a period as a surveillance vessel with the Japanese pearling fleet in the Arafura Sea. In October 1956, ''Quadrant'' again proceeded to the Far East for further exercises, visiting Hong Kong, Singapore, and Manila. By 1957 the frigate was already worn out and the decision to decommission the vessel was made before sister ship s frigate conversion was complete and after the premature decommissioning due to hull failure.

Decommissioning and fate

''Quadrant'' paid off at Sydney on 16 August 1957 and was sold for scrap to the Japanese firm of Kinoshita and Company Limited on 15 February 1963.
