HMS "Cockatrice" was an of the British Royal Navy. She was built by Hawthorn Leslie and Company, launching in 1912 and served throughout the First World War. She was sold for scrap in 1921. Construction. "Cockatrice" was one of three s ordered from the Newcastle upon Tyne shipbuilder Hawthorn Leslie and Company as part of the 1911–1912 shipbuilding programme for the Royal Navy. In all, 20 "Acasta"-class ships were ordered as part of this programme, of which 12, including "Cockatrice", were to the standard Admiralty design with the other 8 ships to their builder's own designs . "Cockatrice" was laid down on 23 October 1911 and launched on 8 November 1912. In 1912, as part of a general reorganisation of the Royal Navy's destroyers into alphabetical classes, the "Acasta"s became the K class, and in 1913, it was decided to switch to names beginning with the class letter, with "Cockatrice" being allocated the name "Kingfisher", but this plan was abandoned for the class and "Cockatrice" completed under her original name in March 1913. "Cockatrice" was long between perpendiculars and overall, with a beam of and a draught of . Displacement was normal and deep load. Four Yarrow  boilers fed steam to direct drive Parsons steam turbines rated at and driving two shafts. This gave a speed of . The ships had a crew of 73 officers and ratings. The ship's main gun armament consisted of three BL Mk VIII guns, with 120 rounds of ammunition carried per gun. Two torpedo tubes were fitted, while two reload torpedoes could be carried. By January 1916, "Cockatrice" was recorded as being fitted with minesweeping gear. In 1916, one of "Cockatrice"s 4-inch guns was converted to a high-angle mount, allowing it to be used for anti-aircraft fire, but  in 1918, this gun, together with both torpedo tubes, was removed to allow a heavy depth charge armament. Service. "Cockatrice" joined her sister ships in the 4th Destroyer Flotilla of the Home Fleet based at Portsmouth. With the outbreak of the First World War in August 1914, the 4th Flotilla, including "Cockatrice", joined the newly established Grand Fleet, based at Scapa Flow in Orkney. "Cockatrice" was damaged during a severe storm in December 1914. "Cockatrice" remained part of the 4th Flotilla in May 1916, but was absent from the Battle of Jutland, when most of the 4th Flotilla took part , as she was undergoing refit. The 4th Flotilla, including "Cockatrice", left the Grand Fleet and moved to the Humber in July 1916, with the role of protecting British minesweepers and deterring German minelayers off the east coast of England. By December that year, "Cockatrice" had relocated again as the 4th Flotilla transferred to Portsmouth to carry out anti-submarine operations in the English Channel, while by March 1917, the 4th Flotilla had moved to Devonport. On 13 and 14 May 1918, "Cockatrice", on patrol with sister ships and , attacked possible submarine contacts with depth charges with no apparent results. "Cockatrice  was still part of the 4th Destroyer Flotilla in August 1918, but by the end of the war had joined the Northern Patrol Force based at Dundee. Disposal.
