HMS Alacrity was a modified Black Swan-class sloop of the Royal Navy, designed primarily as a convoy escort during World War II. Constructed by William Denny and Brothers at their Dunbarton shipyard, she was laid down on 5 April 1943, launched on 1 September 1944, and completed on 13 April 1945. The vessel measured 299 feet 6 inches (91.29 meters) in overall length, with a beam of 38 feet 6 inches (11.73 meters) and a deep load draught of 11 feet 4 inches (3.45 meters). Her standard displacement ranged between 1,350 and 1,490 long tons, increasing to approximately 1,880–1,950 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, Alacrity produced 4,300 shaft horsepower, allowing her to reach a top speed of nearly 19.75 knots (36.58 km/h). Her armament included three twin QF 4-inch (102 mm) Mk XVI guns in dual-purpose mounts suitable for both anti-ship and anti-aircraft roles. Her close-in anti-aircraft defenses consisted of two twin 40 mm Bofors guns and two single Oerlikon 20 mm cannon, later upgraded to include additional Bofors guns post-war. For anti-submarine warfare, she was equipped with a split Hedgehog mortar and carried 110 depth charges. Initially assigned the pennant number U60, HMS Alacrity conducted training in home waters before deploying to the Far East with the British Pacific Fleet, arriving in Colombo after Japan’s surrender. She remained in the Far East post-war, undergoing a refit in New Zealand in 1946, and was reclassified with the pennant number F60. She served with the 1st Escort Flotilla, later the 3rd Frigate Flotilla, until her deployment in the Korean War with United Nations naval forces in 1950. After returning to Portsmouth in 1952, she was placed in reserve and eventually placed on the disposal list in 1956. HMS Alacrity was sold for scrap to W H Arnold Young and was broken up at Dalmuir on 15 December 1956, marking the end of her service.
