HMAS Castlemaine (J244/M244/A248), named for the city of Castlemaine, Victoria, was one of 60 Bathurst-class corvettes constructed during World War II, and one of 36 initially crewed and commissioned solely by the Royal Australian Navy (RAN).
Launched in 1941 and commissioned in 1942, Castlemaine operated during World War II in the waters of Australia, New Guinea, and Timor. She remained in service until 1945, when she was decommissioned into reserve and converted into an immobilised training ship. In 1973, Castlemaine was presented to the Maritime Trust of Australia for conversion to a museum ship. She is one of two surviving examples of the Bathurst class, the other being HMAS Whyalla.
Design and construction
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. The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least , and a range of . 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 top speed, and a range of , 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. Main armament was initially a BL 4-inch Mk IX naval gun on a Mk I mounting, but this was replaced in 1943 by a QF 4-inch Mk XIX gun on a Mk XXIII mounting. 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 Castlemaine) ordered by the RAN, 20 ordered by the British Admiralty but crewed and commissioned as RAN vessels, and 4 for the Royal Indian Navy. Castlemaine, sister ship , and the auxiliary patrol boat were assigned to the operation by Commodore Cuthbert Pope, Naval Officer in Charge Darwin, with Castlemaine the commanding ship.
Decommissioning and preservation
Castlemaine paid off to reserve on 14 December 1945.
