HMAS Rockhampton (J203/M203), named for the city of Rockhampton, Queensland, 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]
See main article: Bathurst-class corvette. 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, and a range of [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 top speed, and a range of, 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 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 Rockhampton) 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]
Rockhampton had a slightly wider beam than other Bathurst class corvettes; greater.[1]
Rockhampton was laid down by Walkers Limited at Maryborough, Queensland on 6 November 1940, launched on 26 June 1941, and commissioned into the RAN on 21 January 1942.[1]
Rockhampton began her career as a convoy escort along the east coast of Australia.[1] Following a series of Japanese submarine attacks along the east coast of Australia, a convoy system was established.[1] Rockhampton and escorted the first Sydney to Brisbane convoy.[1] The corvette remained in this role until January 1944, when she began escorting convoys to and from New Guinea.[1] She underwent refit in Sydney over April and May 1944, before returning to escort duties in New Guinea waters.[1] Rockhampton operated in both Australian and New Guinea waters up until the end of World War II.[1]
Following the end of the war, Rockhampton was involved in the rescue of Dutch and Indonesian prisoners-of-war and the occupation of Ambon.[1] On 8 October 1945, the corvette carried the Sultan of Ternate on his return home.[1] Rockhampton returned to Sydney in November 1945, where she was assigned to minesweeping duties off the east coast of Australia.[1] She later participated in survey duties off the coast of South Australia, before returning to Sydney on 29 April 1946.[1]
The corvette received two battle honours for her wartime service: "Pacific 1942–45" and "New Guinea 1944".[10] [11]
Rockhampton paid off to reserve on 5 August 1946, and was sold to Kino Shito (Australia) Pty Ltd for scrap on 6 January 1961.[1] She departed Australia for Japan under tow by the tug Benton Maru in 1962.
