HMAS Katoomba

HMAS ''Katoomba'' (J204/M204), named after the tourist resort of Katoomba, New South Wales, 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).

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.Stevens, ''The Australian Corvettes'', p. 1Stevens, ''A Critical Vulnerability'', p. 103 The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least , and a range of .Stevens, ''A Critical Vulnerability'', pp. 103–4 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. Construction of the prototype did not go ahead, but the plans were retained.Stevens, ''A Critical Vulnerability'', p. 104 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 ''Katoomba'') ordered by the RAN, 20 ordered by the British Admiralty but crewed and commissioned as RAN vessels, and 4 for the Royal Indian Navy.Stevens, ''A Critical Vulnerability'', pp. 105, 148Donohue, ''From Empire Defence to the Long Haul'', p. 29Stevens et al., ''The Royal Australian Navy'', p. 108

''Katoomba'' was laid down by Poole & Steel at Balmain, New South Wales on 9 September 1940. She was launched on 16 April 1941 by Mrs. Lloyd, then deputy mayoress of Katoomba, and was commissioned into the RAN on 17 December 1941.

Operational history

''Katoomba'' entered active service with an assignment to Darwin, where she arrived on 19 December 1941. The next day, ''Katoomba'', along with sister ships ''Deloraine'' and ''Lithgow'', and the United States destroyer ''Edsall'', was involved in the prosecution and successful sinking of Japanese submarine ''I-124'', the first enemy submarine sunk in Australian waters. ''Katoomba'' was present during the Japanese bombing of Darwin on 19 February, but was not significantly damaged.

At the end of June, ''Katoomba'' was reassigned as a convoy escort and anti-submarine patrol ship in the waters of northern Queensland and New Guinea. On 14 August, ''Katoomba'' was sent to assist United States submarine ''S-39'', which had run aground on a reef off Rossel Island. Attempts to refloat the submarine were unsuccessful, and on 16 August, the corvette left Rossel Island with ''S-39''’s entire crew of 47 embarked. The submarine was gutted and left to break up naturally. On 28 November, ''Katoomba'' and sister ship ''Ballarat'' were attacked by a force of ten Japanese dive bombers. The corvettes escaped without serious damage. ''Katoomba'' was attacked again during January 1943, when a force of six Japanese aircraft attacked the corvette and the Dutch merchant ship ''Van Heutz''. ''Katoomba'' escaped serious damage, but the merchantman was hit, with one man killed and three injured.

In February 1944, ''Katoomba'' ended her escort duties, and after a short period on patrol, was sent to Sydney for refitting. Upon her return to New Guinea waters in early May 1944, the corvette was assigned as an anti-submarine patrol ship. She remained in this role until the start of March 1945, although during this period she was occasionally used as an escort ship. The corvette returned to Australian waters, spent three months in Fremantle, then was assigned to Darwin, where she operated until the end of World War II.

After the war's end, ''Katoomba'' was sent to the Japanese surrender at Timor, before assignment to mine-clearance duties throughout New Guinea waters. She returned to Sydney in October 1946, and was prepared for decommissioning, but was instead reactivated to help clear the coast of Queensland of mines.

''Katoomba'' received three battle honours for her wartime service: "Darwin 1942", "Pacific 1942–45", and "New Guinea 1942–44".

Decommissioning and fate

''Katoomba'' arrived in Fremantle on 16 January 1948, and was paid off into reserve on 2 August. She remained in reserve until 2 May 1957, when she was sold for breaking up as scrap to the Hong Kong Rolling Mills.
