HMS Lassoo was a Laforey-class destroyer constructed for the Royal Navy during the 1910s, embodying the improvements and increased speed characteristic of its class over the preceding Acasta class. The vessel displaced approximately 965 to 1,010 long tons (980 to 1,026 metric tons) and measured 268 feet 10 inches (81.9 meters) in overall length, with a beam of 27 feet 8 inches (8.4 meters) and a draught of 10 feet 6 inches (3.2 meters). Powered by two Parsons direct-drive steam turbines, each driving a single propeller shaft and fueled by four Yarrow boilers, HMS Lassoo generated a total of 24,500 shaft horsepower (18,300 kW). This propulsion system enabled the destroyer to reach a maximum speed of 29 knots (54 km/h; 33 mph). Its fuel capacity of 280 long tons (280 tonnes) of fuel oil provided a range of approximately 1,750 nautical miles (3,240 km; 2,010 miles) at a cruising speed of 15 knots (28 km/h; 17 mph). The ship's crew comprised 74 officers and ratings. In terms of armament, HMS Lassoo was equipped with three single QF 4-inch (102 mm) Mark IV guns, suitable for engaging surface targets, and initially carried two QF 1.5-pounder (37 mm) anti-aircraft guns. These were later replaced by two QF 2-pounder (40 mm) "pom-pom" guns, enhancing her anti-aircraft capabilities. Additionally, she was fitted with two above-water twin mounts for 21-inch (533 mm) torpedoes, allowing for offensive operations against larger vessels. Built during World War I as part of an emergency naval construction program, she was designed by William Beardmore & Company, Dalmuir. Originally slated to be named Magic, she was renamed Lassoo on 15 February 1915 and launched on 24 August 1915. HMS Lassoo's service was brief; she was sunk by the German U-boat SM UB-10 on 13 August 1916 off the Maas lightship in the North Sea, marking a tragic loss during wartime operations.
