HMS Moresby was an Admiralty M-class destroyer serving with the Royal Navy during World War I. Built by J. Samuel White at East Cowes on the Isle of Wight, she was laid down on 1 January 1915 and launched on 20 November 1915. Originally named HMS Marlion, she was renamed before her completion on 7 April 1916 to honor Admiral Fairfax Moresby. The vessel measured 265 feet (80.8 meters) in length overall, with a beam of 26 feet 7 inches (8.1 meters) and a draught of 8 feet 7 inches (2.6 meters). Displacing approximately 1,004 long tons (1,020 metric tons) at normal load, she was powered by three White-Forster boilers driving Parsons steam turbines rated at 25,000 shaft horsepower, enabling her to reach a maximum designed speed of 34 knots (63 km/h). Armament comprised three single QF 4-inch (102 mm) guns positioned along the centerline, two twin torpedo mounts for 21-inch (533 mm) torpedoes, and a single 2-pounder (40 mm) "pom-pom" anti-aircraft gun. For anti-submarine warfare, she was equipped with two depth charge chutes after February 1916, with increasing capacity throughout the war. Her crew complement was about 80 officers and ratings. During her service, HMS Moresby joined the Grand Fleet’s Thirteenth Destroyer Flotilla and participated notably in the Battle of Jutland in May 1916. She initially served as cover for the seaplane tender Engadine and later engaged in attack runs against German vessels, launching torpedoes at the battleship Markgraf and narrowly missing the battlecruiser Von der Tann. She also saw action in anti-submarine operations, notably sinking U-110 in March 1918 with the destroyer Michael. After the war, HMS Moresby was placed in reserve and ultimately sold for scrap on 9 May 1921. Her service record highlights her active role in naval combat and fleet operations during a pivotal period of maritime warfare, illustrating the capabilities and importance of the Admiralty M-class destroyers in the Royal Navy’s wartime fleet.
