HMS Raider was a Royal Navy R-class destroyer launched in 1916, serving during World War I primarily with the Grand Fleet. As the second vessel of her class, she was constructed by Swan Hunter & Wigham Richardson at Wallsend, with her keel laid in October 1915 and launched on 17 July 1916. Raider measured 265 feet (80.8 meters) between perpendiculars and 276 feet (84.1 meters) overall, with a beam of 26 feet 8 inches (8.13 meters) and a mean draught of 9 feet (2.7 meters). Her displacement was 975 long tons (991 tons) at normal load, increasing to 1,065 long tons (1,082 tons) at deep load. Powered by three Yarrow boilers and two Brown-Curtis geared steam turbines rated at 27,000 shaft horsepower, Raider achieved a speed of 36 knots (67 km/h). She carried 296 long tons (301 tons) of fuel oil, granting her a range of approximately 3,450 nautical miles (6,390 km) at 15 knots. The ship's armament included three single 4-inch (100 mm) Mk IV guns, one on the forecastle, one aft on a raised platform, and one between the funnels. She also mounted a single 2-pounder "pom-pom" anti-aircraft gun and two twin 21-inch (533 mm) torpedo tubes. Raider's wartime service involved anti-submarine patrols, notably east of the Shetland Islands in June 1917, although she did not succeed in sinking any German submarines. After the war, she was stationed initially at Nore in reserve, then returned to active duty at Harwich in November 1919. She participated in memorial services in 1920 and was briefly deployed to Derry and Lough Swilly in July 1923 during the Irish Civil War. In the mid-1920s, the Navy prepared many older destroyers for decommissioning, and Raider was refitted to join the Portland Anti-Submarine Flotilla, where she was used for training in anti-submarine warfare techniques such as ASDIC. However, she was ultimately decommissioned and sold for scrap in 1927. Her service exemplifies the transition period of naval warfare, moving from traditional gun and torpedo armament toward anti-submarine tactics.
