HMS Onslow was an Admiralty M-class destroyer constructed for the Royal Navy during World War I, representing an improved and faster design over the preceding Laforey class. Displacing approximately 971 long tons, the vessel measured 273 feet 4 inches (83.3 meters) in length, with a beam of 26 feet 8 inches (8.1 meters) and a draught of 9 feet 8 inches (2.9 meters). Powered by three Parsons direct-drive steam turbines driven by four Yarrow boilers, HMS Onslow could reach a maximum speed of 34 knots (63 km/h). Her propulsion system generated a total of 25,000 shaft horsepower, and she carried up to 237 long tons (241 tonnes) of fuel oil, which provided a range of 2,100 nautical miles (3,900 km) at 15 knots. The ship's crew numbered around 76 officers and ratings. Armament on HMS Onslow included three single QF 4-inch (102 mm) Mark IV guns and two QF 1.5-pounder (37 mm) anti-aircraft guns, which were later replaced by a pair of QF 2-pounder (40 mm) "pom-pom" guns. She was also equipped with two twin mounts for 21-inch (533 mm) torpedoes, enhancing her offensive capabilities. Launched on 15 February 1916 and completed by April of the same year, HMS Onslow was built by Fairfield Shipbuilding & Engineering Company at Govan. Her first commanding officer was John Tovey, who later became Admiral of the Fleet. During her service, she played a notable role in escorting transports carrying British troops during the Easter Rising in Ireland in April 1916. HMS Onslow participated prominently in the Battle of Jutland in 1916, where she was badly damaged. Despite her injuries, she pressed home attacks against enemy vessels, including a cruiser and a line of battlecruisers. Under heavy fire, she was towed out of action by HMS Defender, which sustained damage itself. The battle report lauded her and Defender’s gallantry, with both officers receiving the Distinguished Service Order (DSO). Following her recovery, HMS Onslow was eventually sold for scrap in October 1921, marking the end of her brief but distinguished service life.
