HMS Tactician was an Admiralty S-class destroyer built for the Royal Navy, launched on 7 August 1918. As one of thirty-three ships ordered in June 1917, it represented a development of the R class, featuring minor design modifications such as the relocation of the searchlight aft. The vessel measured 276 feet (84 meters) in overall length, with a length between perpendiculars of 265 feet (81 meters), a beam of 26 feet 8 inches (8.13 meters), and a draught of 9 feet 10 inches (3.00 meters). Its displacement was 1,075 long tons (1,092 metric tons) normal and 1,221 long tons (1,241 metric tons) at deep load. Powered by three Yarrow boilers feeding two Brown-Curtis geared steam turbines rated at 27,000 shaft horsepower, HMS Tactician could reach a maximum speed of 36 knots (67 km/h). Its fuel capacity of 301 long tons (306 metric tons) allowed for a range of approximately 2,750 nautical miles at 15 knots. The ship's armament consisted of three QF 4-inch (102 mm) guns on the centerline, complemented by a single 40 mm (1.6-inch) 2-pounder anti-aircraft gun, and four 21-inch (533 mm) torpedo tubes in two twin mounts (initially intended to carry two 18-inch torpedo tubes on each side, but these were replaced to accommodate heavier torpedoes). Additionally, it was equipped with four depth charge chutes and typical anti-submarine equipment. Constructed by William Beardmore and Company in Dalmuir, the vessel was laid down on 21 November 1917, launched on 7 August 1918, and completed by 23 October 1918. Upon commissioning, HMS Tactician joined the Fourteenth Destroyer Flotilla of the Grand Fleet, but it saw no combat action before the end of World War I, as the war concluded shortly after its commissioning. Following the war, HMS Tactician remained with the fleet until the dissolution of the Grand Fleet, after which it was placed in reserve at Nore in 1919. The vessel's condition deteriorated over the subsequent years. In 1930, after the signing of the London Naval Treaty which limited destroyer tonnage, HMS Tactician was deemed unfit for active service and was sold for scrapping on 5 February 1931. Its ship badge, featuring a chessboard and the phrase "Check-mate," was preserved and later used by the Western Approaches Tactical Unit and the Royal Navy Tactical School.
