Design and construction

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

Cessnock was laid down by Cockatoo Docks and Engineering at Sydney, New South Wales on 16 April 1941.^[1] She was launched on 17 October 1941 by Lady Gordon, wife of Sir Thomas Gordon, a director of the constructing firm, and commissioned on 26 January 1942.^[1]

Operational history

After a period of working up, Cessnock commenced duty as an escort vessel and escorted Allied shipping travelling between Townsville and New Guinea until September 1942.^[1] Cessnock was then assigned as an anti-submarine patrol ship operating in Western Australian waters from October until November 1942, when she was assigned to the British Eastern Fleet and based in Kenya.^[1]

Cessnock escorted Allied convoys in the Indian Ocean and Mediterranean Sea during 1943 and 1944.^[1] In January 1945 she returned to Australia and became part of the British Pacific Fleet in February.^[1] The ship operated as an escort in the Pacific until the end of the war.^[1]

Cessnock was present in Tokyo Bay on Victory over Japan Day (2 September 1945), when the Japanese Instrument of Surrender was signed.^[10]

Four battle honours were awarded to Cessnock for her wartime service: "Pacific 1942", "New Guinea 1942", "Indian Ocean 1942–45", and "Sicily 1943".^[11][12]

Fate

Cessnock paid off on 12 July 1946 and was sold for scrap to the Nan Chiao Shipping and Salvage Company of Shanghai, China on 23 April 1947.^[1]
