HMS Umpire was a modified Admiralty R-class destroyer built for the Royal Navy, launched on 9 June 1917 by William Doxford & Sons of Sunderland. As a modified R-class vessel, Umpire incorporated design enhancements from the Yarrow Later M class, primarily aimed at improving seaworthiness in bad weather. The ship measured 276 feet (84.1 meters) in length overall, with a beam of 27 feet (8.2 meters) and a draught of 11 feet (3.4 meters). Displacing approximately 1,035 long tons (1,052 metric tons) at normal load, Umpire was powered by three Yarrow boilers supplying two Brown-Curtis geared steam turbines rated at 27,000 shaft horsepower, enabling a top speed of 36 knots (67 km/h). Its fuel capacity allowed for a range of 3,450 nautical miles at 15 knots. The vessel's armament comprised three single QF 4-inch (102 mm) guns positioned along the centerline—one on the forecastle, one aft on a raised platform, and one between the funnels—along with an increased elevation that extended its range to 11,000 meters. Additionally, it was equipped with a single 2-pounder "pom-pom" anti-aircraft gun and twin 21-inch torpedo tubes, with a crew complement of 82 officers and ratings. During World War I, HMS Umpire served with the Thirteenth Destroyer Flotilla of the Grand Fleet, actively participating in escort duties and naval battles, including the Second Battle of Heligoland Bight in November 1917. She played a notable role in launching torpedoes at German vessels and assisted in rescuing aviation pioneer Jack McCleery in 1918. Post-war, she was transferred to the Fifth Destroyer Flotilla of the Home Fleet and later placed in reserve in 1919 as the Royal Navy downsized. Umpire continued to serve in various capacities, including rescuing Gwendolin Huggins in 1924, the founder of Veterans Aid, and escorting the Sultan of Oman's visit in 1928. Decommissioned and sold for scrap in 1930, HMS Umpire’s service exemplifies the wartime evolution of destroyer design and the Fleet’s strategic roles during and after WWI.
