HMAS Bunbury (J241/M241), named for the city of Bunbury, Western Australia, was one of 60 Bathurst class corvettes constructed during World War II, and one of 36 initially manned and commissioned solely by the Royal Australian Navy (RAN).[1]

Design and construction[edit]

In 1938, the Australian Commonwealth Naval Board (ACNB) identified the need for a general purpose 'local defence vessel' capable of both anti-submarine and mine-warfare duties, while easy to construct and operate.[2][3] The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least 10 knots (19 km/h; 12 mph), and a range of 2,000 nautical miles (3,700 km; 2,300 mi)[4] The opportunity to build a prototype in the place of a cancelled Bar-class boom defence vessel saw the proposed design increased to a 680-ton vessel, with a 15.5 knots (28.7 km/h; 17.8 mph) top speed, and a range of 2,850 nautical miles (5,280 km; 3,280 mi), armed with a 4-inch gun, equipped with asdic, and able to fitted with either depth charges or minesweeping equipment depending on the planned operations: although closer in size to a sloop than a local defence vessel, the resulting increased capabilities were accepted due to advantages over British-designed mine warfare and anti-submarine vessels.[2][5] Construction of the prototype HMAS Kangaroo did not go ahead, but the plans were retained.[6] The need for locally built 'all-rounder' vessels at the start of World War II saw the "Australian Minesweepers" (designated as such to hide their anti-submarine capability, but popularly referred to as "corvettes") approved in September 1939, with 60 constructed during the course of the war: 36 (including Bunbury) ordered by the RAN, 20 ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.[2][7][8][9][1]

Bunbury was laid down by Evans Deakin and Company at Brisbane on 1 November 1941, launched on 16 May 1942 by Mrs. F. A. Cooper, wife of the Treasurer of Queensland, and commissioned on 3 January 1943.

Operational history[edit]

The corvette received two battle honours for her service during World War II; "Pacific 1943–45" and "New Guinea 1943–44".[10][11]


Bunbury paid off to reserve on 26 August 1946 and was sold for scrap to the Kinoshita Company of Japan on 6 January 1961.
