HMAS Tamworth (J181/B250/A124), named for the city of Tamworth, New South Wales, was one of 60 Bathurst-class corvettes constructed during World War II and one of 20 built on Admiralty order but manned by personnel of and later commissioned into the Royal Australian Navy (RAN).^[1] Tamworth later saw service in the Royal Netherlands Navy (RNLN) and in the Indonesian Navy (TNI-AL).^[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 Mk XIX 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 Tamworth) ordered by the British Admiralty but manned and commissioned as RAN vessels, and 4 for the Royal Indian Navy.^[2]^[7]^[8]^[9]^[1]

Tamworth was laid down by Walkers Limited at Maryborough, Queensland on 25 August 1941.^[1] She was launched on 14 March 1942 by Mrs. A. M. Horsburgh, the wife of one of the shipyard's directors, and commissioned on 8 August 1942.^[1]

Operational history

From February 1943 until January 1945, Tamworth was assigned to the British Eastern Fleet.^[1] Following this, she was deployed with the British Pacific Fleet.^[1] Tamworth returned to Australian operational control on 28 September 1945.^[1] Tamworth earned two battle honours for her wartime service, "Pacific 1942–45" and "Indian Ocean 1943–44".^[10]^[11]

After a brief period of service as a training vessel in Australian waters was transferred to the Royal Netherlands Navy on 30 April 1946.^[1] In RNLN service, the ship operated under the name HNLMS Tidore, and served until December 1949.^[1]

Following this, the ship was transferred to the Indonesian Navy, renamed RI Pati Unus, and served until disposal in 1969.^[1]
