HMS Cochrane ( 1905 ) HMS " Cochrane " was a armoured cruiser built for the Royal Navy in the first decade of the 20th century . She served in the 2nd Cruiser Squadron during the First World War under Rear - Admiral Herbert Heath , taking part in the Battle of Jutland in 1916 . She was based in Murmansk in mid - 1918 during the Allied intervention in the Russian Civil War . She became stranded in the River Mersey on 14 November 1918 and broke in two . The wreck was broken up in place by June 1919 . Description . " Cochrane " displaced as built and fully loaded , with a length of , a beam of and a draft of . She was powered by four - cylinder triple - expansion steam engine s , driving two shafts , which developed a total of and gave a maximum speed of . The engines were powered by 19 Yarrow water - tube boilers and six cylindrical boilers . The ship carried a maximum of of coal and an additional of fuel oil that was sprayed on the coal to increase its burn rate . At full capacity , she could steam for at a speed of . Her main armament consisted of six BL Mark X guns in single Mk V turrets distributed in two centerline turrets ( one each fore and one aft ) and four turrets disposed in the corners about the funnels . Her secondary armament of four BL Mark II or Mark V guns in single Mk II turrets was carried amidships , between the wing 9 . 2 - inch guns . Twenty - six Vickers QF 3 pounders were fitted , ten on turret roofs and eight each on the forward and aft superstructures . The last four ships of the cruisers had a secondary armament of turreted 7 . 5 - inch guns rather than the guns in open barbettes of the first two ships ; these latter four were sometimes referred to as the " Warrior " class . Because of the extra topweight of the turrets in comparison to their half - sisters their stability was reduced which made them very good seaboats and steady gun platforms . Wartime modifications . A single Hotchkiss QF 6 - pounder anti - aircraft gun on a high - angle Mark Ic mounting was mounted on the quarterdeck in 1915 . It had a maximum depression of 8° and a maximum elevation of 60° . The gun fired a shell at a muzzle velocity of at a rate of fire of 20 rounds per minute . They had a maximum ceiling of , but an effective range of only . It was replaced by a QF 3 inch 20 cwt guns on a high - angle Mark II mount in 1916 . This gun had a maximum depression of 10° and a maximum elevation of 90° . It fired a shell at a muzzle velocity of at a rate of 12 – 14 rounds per minute . It had a maximum effective ceiling of . A pair of Vickers QF 3 pounder on HA Mark III mountings were probably installed amidships during 1915 – 16 . They could elevate to + 80° and depress to - 5° . This gun fired a shell at a muzzle velocity of at a rate of 25 rounds per minute . They had a maximum ceiling of , but an effective range of only . The guns on top of ' A ' and ' Y ' turrets were removed in 1915 – 16 . The aftermost 3 - pounder guns on the superstructure were removed during 1917 as well as the guns on top of the forward 9 . 2 - inch wing turrets . This reduced her total to twenty 3 - pounder guns , excluding the AA guns . Some of these guns were landed at Murmansk while she was based there . Seventeen 3 - pounders were on board when she was lost in 1919 , but it is unclear if that total includes the AA guns . " Cochrane " s foremast was converted to a tripod mast to support the weight of a fire - control director in 1917 , but the director was not actually fitted until August 1918 . Service . " Cochrane " was laid down on 24 March 1904 and launched on 28 May 1905 at Fairfield Shipbuilding and Engineering , Govan , Scotland . The ship was commissioned with a nucleus crew on 18 February 1907 and cost £1 , 193 , 121 . She " joined the Nore Division of the Home Fleet on 6 March 1907 and shortly afterwards was brought into to full commission for service with the 5th Cruiser Squadron . On 1 April 1909 she recommissioned for service with the 2nd Cruiser Squadron with which she remained until September 1917 . " She escorted the Royal Yacht " Medina " in 1911 – 12 . " Cochrane " , accompanied by her sister and three other armoured cruisers were sent to reinforce the defences of the Shetland Islands on 2 August 1914 , days before the start of the First World War . She , and her squadron , were assigned to the Grand Fleet for most of the First World War . She took part in the Battle of Jutland on 31 May – 1 June 1916 , along with the cruisers , , and under the command of Rear - Admiral Heath . However , the ship remained unengaged throughout the battle , and did not fire her 9 . 2 or 7 . 5 - inch guns at all during the battle . " Cochrane " was transferred to the North America and West Indies station in November 1917 , but rejoined the 2nd Cruiser Squadron early in 1918 . She was based in Murmansk between March and September 1918 during the Allied intervention in the Russian Civil War . She ferried Soviet troops to Pechenga on 3 May to forestall an attempt by White Finns to seize the town . On 14 November 1918 she was stranded in the Mersey Estuary , while under the control of the pilot , and later broke in two , becoming a total loss . The wreck had been broken up in situ by June 1919 .
