HMS Sharpshooter was a Halcyon-class minesweeper constructed at Devonport Dockyard, launched on 10 December 1936, and completed in December 1937. Measuring approximately 245 feet 6 inches (74.83 meters) in overall length and 230 feet (70.10 meters) between perpendiculars, she had a beam of 33 feet 6 inches (10.21 meters) and a draught of 10 feet 3 inches (3.12 meters) at deep load. Her displacement was 835 long tons (848 tonnes) standard and 1,330 long tons (1,350 tonnes) at deep load. The vessel was powered by two Admiralty 3-drum water-tube boilers driving geared steam turbines, which developed 1,750 shaft horsepower, enabling her to reach a speed of 17 knots (20 mph). Her armament initially comprised two QF 4-inch (102 mm) Mk V guns on High-Angle mounts, suitable for anti-aircraft roles, and a quadruple Vickers .50 machine gun mount for close-in defense. During the war, her armament was modified: one 4-inch gun was removed, and the machine guns replaced with 4–8 Oerlikon 20 mm cannons. She carried up to 40 depth charges for escort duties and had a crew of 80 officers and ratings. Commissioned in 1937, HMS Sharpshooter served with the 1st Minesweeping Flotilla, initially based at Portland, later moving to Scapa Flow. During WWII, she performed minesweeping operations around Scapa Flow, Loch Ewe, and the Clyde estuary. Notably, she participated in the Dunkirk evacuation in May 1940, making multiple runs and rescuing troops. Her bow was damaged in a collision with the steamer St Helier during the evacuation, requiring repairs. Sharpshooter was actively involved in Arctic convoy escort duties, notably sinking the German U-boat U-655 in 1942 after a collision that damaged her bow. She also participated in Operation Husky in the Mediterranean, contributing to minesweeping and convoy escort activities. Post-war, she was converted into a survey ship in 1945, renamed HMS Shackleton in 1953, and undertook survey missions in Malaya and Borneo, discovering submerged wrecks. Throughout her service, HMS Sharpshooter was notable for her versatility—serving as a minesweeper, escort vessel, and survey ship—contributing significantly to wartime mine clearance, convoy protection, and post-war maritime surveying. She was decommissioned and scrapped in 1965, marking the end of her distinguished maritime career.
