The Arethusa-class cruisers were intended to lead destroyerflotillas 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[3] and 5,795 long tons (5,888 t) at full load. Arethusa was powered by four Parsonssteam 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).[4] She carried 840 long tons (853 t) tons of fuel oil[3] that gave a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 16 knots (30 km/h; 18 mph).[5]
She was launched on 14 May 1914 at William Beardmore and Company shipyard. On her commissioning she was assigned as the leader to the 2nd Destroyer Flotilla of the Harwich Force, guarding the eastern approaches to the English Channel. On 4 May 1916, she took part in the shooting down of Zeppelin L 7. At the Battle of Jutland, she was the flagship of the 1st Light Cruiser Squadron under Commodore E.S. Alexander-Sinclair. She was the first ship to report the presence of German ships, triggering the battle. Galatea was also the first to receive a hit by the German light cruiser SMS Elbing, but no explosion occurred. She was sold for scrapping on 25 October 1921.[6]Mount Galatea in Alberta, Canada is named after this ship.
