HMS Nereus was an Admiralty M-class destroyer built for the Royal Navy during World War I. Launched on 24 February 1916 and completed in May of the same year, she measured approximately 265 feet (80.8 meters) in length between perpendiculars, with a beam of 26 feet 7 inches (8.1 meters) and a draught of 8 feet 7 inches (2.6 meters). Displacing around 994 long tons (1,010 tonnes) at normal load, the vessel was powered by three oil-fired Yarrow boilers feeding Parsons steam turbines rated at 25,000 shaft horsepower, which enabled her to reach a designed speed of 34 knots (63 km/h). Her armament comprised three single QF 4-inch (102 mm) Mk IV guns positioned along the centerline—one on the forecastle, one aft on a raised platform, and one amidships—along with two twin torpedo mounts for 21-inch (533 mm) torpedoes. Additionally, she was equipped with a single QF 2-pounder (40 mm) "pom-pom" anti-aircraft gun and two depth charge chutes for anti-submarine defense. Her complement was approximately 80 officers and ratings. Constructed by John I. Thornycroft & Company in Woolston, Southampton (yard number 790), HMS Nereus was assigned to the Grand Fleet’s Thirteenth Destroyer Flotilla, based at Rosyth, where she supported convoy operations and participated in fleet patrols. Notably, on 13 December 1916, her forecastle was damaged by rough seas during a hunting operation, leading to the flotilla’s withdrawal. She also took part in a late-war sortie against the German High Seas Fleet on 24 April 1918, although she saw no combat. Following the war, Nereus was transferred to the Fourth Destroyer Flotilla at Devonport but was soon worn out by demanding high-speed operations in harsh weather conditions, exacerbated by her ungalvanized hull. Decommissioned in 1921 after less than five years of service, she was sold to Cashmore of Newport and broken up in 1922. Her ship’s bell was preserved and is now housed in the Imperial War Museum, serving as a relic of her brief but active wartime career.
