HMS Royalist was one of eight Arethusa-class cruiser (1913) light cruisers built for the Royal Navy in the 1910s. She fought in the First World War, participating in the Battle of Jutland. Following the war, she was scrapped.

Design and description

The Arethusa-class cruisers were intended to lead destroyer flotillas and defend the fleet against attacks by enemy destroyers. The ships were 456 ft long overall, with a beam of 49 ft and a deep draught of 15 ft. Displacement was 5185 LT at normal and 5795 LT at full load. Royalist was powered by four Parsons steam turbines, each driving one propeller shaft, which produced a total of 40000 ihp. The turbines used steam generated by eight Yarrow boilers which gave her a speed of about 28.5 kn. She carried 840 LT tons of fuel oil that gave a range of 5000 nmi at 16 kn. The main armament of the Arethusa-class ships was two BL 6-inch (152 mm) Mk XII guns that were mounted on the centreline fore and aft of the superstructure and six QF 4-inch Mk V guns in waist mountings. They were also fitted with a single QF 3-pounder 47 mm anti-aircraft gun and four 21 in torpedo tubes in two twin mounts.

Construction and career

She was launched on 14 January 1915 at William Beardmore and Company's shipyard. On being commissioned, she was assigned to the 4th Light Cruiser Squadron of the Grand Fleet. From 31 May to 1 June 1916 Royalist took part in the Battle of Jutland. She survived the battle and in February 1917 was reassigned to the 1st Light Cruiser Squadron of the Grand Fleet. She survived the First World War, and was sold for scrapping on 24 August 1922 to Cashmore, of Newport.
