HMAS Cairns (J183), named for the city of Cairns, Queensland, was one of 60 Bathurst-class corvettes constructed during World War II and one of 20 built for the Admiralty but manned by personnel of and commissioned into the Royal Australian Navy (RAN).^[1]

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.^[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 ordered by the RAN, 20 (including Cairns) ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.^{[2][7][8][9][1]}

Cairns was laid down by Walkers Limited at Maryborough, Queensland on 31 March 1941.^[1] She was launched on 7 October 1941 by Mrs. R. D. Walker, wife of the Works Manager of Walkers Limited, and commissioned into the RAN on 11 May 1942.^[1]

Operational history

Royal Australian Navy

From entering service until 16 October 1942, Cairns was based in Fremantle and operated as a convoy escort, anti-submarine patroller, and minesweeper.^[1] On 16 October, the corvette was reassigned to the British Eastern Fleet and ordered to Kilindini, Kenya, arriving on 14 November.^[1]

Cairns remained with the Eastern Fleet until January 1945.^[1] Most of this time was spent on patrol or escort duties in the Indian Ocean. The corvette was reassigned to the Mediterranean from June until September 1943.^[1] During this time, Cairns was involved in the Allied invasion of Sicily.^[1] On 11 February 1944, a convoy Cairns was assigned to was attacked by Ro-110.^[1] The corvette was involved in the successful destruction of the submarine, but one convoy ship was torpedoed.^[1] Following a refit in Adelaide from May to July 1944, Cairns was redeployed to Colombo, which was her base of operations until January 1945, when the corvette was sent back to Australia.^[1]

On arrival in Australian waters, Cairns was assigned to the British Pacific Fleet.^[1]

The ship received four battle honours for her wartime service: "Pacific 1942–45", "Indian Ocean 1942–45", "Sicily 1943", and "Okinawa 1945".^[10][11]

Royal Netherlands Navy

Following the end of World War II, all Admiralty-owned Bathurst class corvettes were disposed of. Cairns was paid off in Brisbane on 17 January 1946.^[1] She was immediately recommissioned into the Royal Netherlands Navy (RNLN) and renamed HNLMS Ambon.^[1]

Indonesian Navy

Following four years of service with the RNLN, the ship was transferred to the Indonesian Navy on 6 April 1950 and renamed KRI Banteng.^[1]

Fate

The corvette was broken up for scrap in April 1968.^[1]
