HMS Penelope (1914)

The Arethusa-class cruisers were intended to lead destroyer flotillas and defend the fleet against attacks by enemy destroyers. The ships were 456 feet 6 inches (139.1 m) long overall, with a beam of 49 feet 10 inches (15.2 m) and a deep draught of 15 feet 3 inches (4.6 m). Displacement was 5,185 long tons (5,268 t) at normal[1] and 5,795 long tons (5,888 t) at full load. Penelope was powered by four Parsons steam turbines, each driving one propeller shaft, which produced a total of 40,000 indicated horsepower (30,000 kW). The turbines used steam generated by eight Yarrow boilers which gave her a speed of about 28.5 knots (52.8 km/h; 32.8 mph).[2] She carried 840 long tons (853 t) tons of fuel oil[1] that gave a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 16 knots (30 km/h; 18 mph).[3]

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 (1.9 in) anti-aircraft gun and four 21 in (533 mm) torpedo tubes in two twin mounts.[2]

She was launched on 25 August 1914 at Vickers Limited's shipyard. Unlike her sisters, she carried an extra 4-inch anti-aircraft gun in place of two 3-inch anti-aircraft guns. In August 1915, she was assigned to the 5th Light Cruiser Squadron of the Harwich Force, guarding the eastern approaches to the English Channel. On 25 April 1916 Penelope was damaged by a torpedo from the German submarine UB-29 off the Norfolk coast. She was repaired and in March 1918 was reassigned to the 7th Light Cruiser Squadron of the Grand Fleet. She survived to the end of the First World War, and was sold for scrap in October 1924 to Stanlee, of Dover.[4]
