HMS Inconstant was an Arethusa-class light cruiser constructed for the Royal Navy in the 1910s, representing a key component of British naval forces during World War I. She was launched on 6 July 1914 by William Beardmore and Company. The vessel measured approximately 456 feet 6 inches (139.1 meters) in overall length, with a beam of 49 feet 10 inches (15.2 meters) and a deep draught of 15 feet 3 inches (4.6 meters). Displacing 5,185 long tons (5,268 tonnes) at normal load and up to 5,795 long tons (5,888 tonnes) at full load, HMS Inconstant was designed for fleet leading and destroyer flotilla guidance. Powered by four Parsons steam turbines, each driving a separate propeller shaft, she generated a total of 40,000 indicated horsepower (30,000 kW). These turbines were fueled by eight Yarrow boilers, enabling her to reach a top speed of approximately 28.5 knots (52.8 km/h; 32.8 mph). Her fuel capacity of 840 long tons (853 tonnes) of oil provided an operational range of about 5,000 nautical miles (9,300 km; 5,800 miles) at a cruising speed of 16 knots. The ship's armament comprised two BL 6-inch (152 mm) Mk XII guns mounted on the centerline fore and aft, six QF 4-inch (102 mm) guns in waist mountings, a single QF 3-pounder (47 mm) anti-aircraft gun, and four 21-inch (533 mm) torpedo tubes arranged in two twin mounts. HMS Inconstant served with the 1st Light Cruiser Squadron of the Grand Fleet and participated in the Battle of Jutland from 31 May to 1 June 1916. She survived the battle and the war, continuing her service until she was sold for scrapping on 9 June 1922 to Cashmore in Newport. Her operational history and participation in a pivotal naval engagement underscore her role in early 20th-century naval warfare.
