HMS Opossum was a modified Black Swan-class sloop of the Royal Navy, constructed by William Denny and Brothers at Dumbarton. Laid down on 28 July 1943 and launched on 30 November 1944, she was commissioned on 16 June 1945 with the pennant number U33. The vessel measured approximately 299.5 feet in length overall, with a beam of 38 feet 6 inches and a draught of 11 feet 4 inches at deep load. Her displacement ranged from 1,350 to 1,490 long tons standard, increasing to between 1,880 and 1,950 long tons at deep load, depending on her armament and equipment. Powered by two Admiralty three-drum water-tube boilers driving Parsons geared steam turbines, Opossum’s machinery produced 4,300 shaft horsepower, allowing her to reach a maximum speed of nearly 20 knots. Her armament included three twin QF 4-inch Mk XVI guns, capable of both anti-ship and anti-aircraft roles. Her close-in anti-aircraft defenses comprised various Bofors and Oerlikon cannons, with her initial complement including two twin 40 mm Bofors guns and multiple twin and single 20 mm Oerlikon cannons. She was also equipped with 110 depth charges for anti-submarine warfare and later received a Hedgehog anti-submarine mortar. Opossum’s early service saw her join the British Pacific Fleet shortly after World War II ended, operating out of Hong Kong. Notably, in May 1946, she rescued eight survivors from a crashed RAAF Liberator near Mindanao. After a refit in Sydney, she returned to Britain in late 1947, entering reserve at Portsmouth. Recommissioned in 1952, she served in the Far East, participating in patrols, exercises such as Operation Full Back, and engagements during the Korean War and Malayan Emergency, including shelling suspected Communist targets. Her career concluded with her return to Britain in 1958, after which she joined the 7th Frigate Squadron on the South Atlantic Station. She was decommissioned and sold for scrap in 1960, arriving at the breakers yard on 26 April. The HMS Opossum thus exemplifies the transition of Royal Navy sloops from wartime patrol vessels to post-war auxiliary roles, with notable service in the Pacific, Korean War, and Malayan Emergency.
