HMS Parthian was an Admiralty M-class destroyer constructed for the Royal Navy during the First World War. Launched on 3 July 1916 by Scotts Shipbuilding and Engineering Company in Greenock, she measured 265 feet (80.8 meters) in overall length, with a beam of 26 feet 8 inches (8.1 meters) and a draught of 9 feet 3 inches (2.8 meters). Displacing approximately 994 long tons (1,010 tonnes) at normal load and up to 1,025 long tons (1,041 tonnes) fully loaded, Parthian was powered by three Yarrow boilers feeding two Brown-Curtis steam turbines, rated at 25,000 shaft horsepower, enabling her to reach a designed top speed of 34 knots (63 km/h). Her armament comprised three 4-inch (102 mm) guns positioned along the centerline—one on the forecastle, one aft on a raised platform, and one between the funnels—along with a single 2-pounder (40 mm) anti-aircraft gun and two twin mounts for 21-inch (533 mm) torpedoes. Her complement consisted of approximately 76 officers and ratings. Constructed at Scotts' yard number 472, Parthian was commissioned into the Royal Navy and assigned initially to the Grand Fleet. In February 1917, she was transferred to the Southwest Approaches, based from Cobh, Ireland, to conduct anti-submarine and escort duties amidst rising German U-boat activity. She actively engaged enemy submarines, notably assisting SS Arataca against U-44 and pressing an attack on an unidentified U-boat in April 1917, using gunfire, depth charges, and attempted ramming. Parthian also participated in the arrival of the first US Navy destroyers in European waters in May 1917, and her successful anti-submarine actions were notable, including a credited sinking of a submarine after a swift and vigilant engagement described by Admiral Sir Lewis Bayly. Following the Armistice in November 1918, Parthian was placed in reserve. She was transferred to Devonport in October 1919 and, after a period of deactivation, was decommissioned and sold for scrapping on 8 November 1921. Her service exemplifies the critical role of destroyers in wartime patrol, convoy escort, and anti-submarine warfare, marking her as a significant component of Britain’s naval efforts during the tumult of the First World War.
