HMS Lassoo was a Laforey-class destroyer built for the Royal Navy during the 1910s.
Description
The Laforey class were improved and faster versions of the preceding Acasta class.[1] They displaced 965–1,010 long tons (980–1,026 t). The ships had an overall length of 268 feet 10 inches (81.9 m), a beam of 27 feet 8 inches (8.4 m) and a draught of 10 feet 6 inches (3.2 m). Lassoo was powered by two Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by four Yarrow boilers.[2] The turbines developed a total of 24,500 shaft horsepower (18,300 kW) and gave a maximum speed of 29 knots (54 km/h; 33 mph). The ships carried a maximum of 280 long tons (280 t) of fuel oil that gave them a range of 1,750 nautical miles (3,240 km; 2,010 mi) at 15 knots (28 km/h; 17 mph). The ships' complement was 74 officers and ratings.[3]
The ships were armed with three single QF 4-inch (102 mm) Mark IV guns and two QF 1.5-pounder (37 mm) anti-aircraft guns. These latter guns were later replaced by a pair of QF 2-pounder (40 mm) "pom-pom" anti-aircraft guns. The ships were also fitted with two above-water twin mounts for 21-inch (533 mm) torpedoes.[3]
Construction and service
She was built during the First World War as part of an emergency program of naval construction, to an Admiralty design by William Beardmore & Company, Dalmuir. She was originally to have been named Magic but she was renamed Lassoo on 15 February 1915 before being launched on 24 August 1915. She was sunk by the German U-boat SM UB-10 on 13 August 1916 off the Maas lightship in the North Sea.
