HMAS Horsham (J235/M235), named for the city of Horsham, Victoria, 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]

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 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 (including Horsham) 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]}

Horsham was laid down by HMA Naval Dockyard at Melbourne, Victoria on 26 June 1941. ^[1] She was launched on 16 May 1942, and was commissioned into the RAN on 18 November 1942.

Operational history

Horsham entered active service in January 1943. ^[1] She was initially assigned to Fremantle as an anti-submarine patrol ship, where she remained until August 1944. ^[1] The corvette was then deployed to Darwin as a survey ship, and remained there until the end of World War II. ^[1] In September 1945, Horsham was present at the Japanese surrender of Timor. ^[1] She continued in the survey role until November 1945, when she returned to Fremantle. ^[1]

Decommissioning and fate

Horsham paid off into reserve in Fremantle on 17 December 1945. ^[1] She was sold for scrapping to the Hong Kong Delta Shipping Company on 8 August 1956. ^[1]
