HMS Cochrane was a Warrior-class armoured cruiser constructed for the Royal Navy in the early 20th century. Laid down on 24 March 1904 and launched on 28 May 1905 at Fairfield Shipbuilding and Engineering in Govan, Scotland, she displaced approximately 13,550 long tons (13,770 tonnes) as built, increasing to 14,500 long tons (14,700 tonnes) when fully loaded. The vessel measured 505 feet 4 inches (154.0 meters) in length, with a beam of 73 feet 6 inches (22.4 meters) and a draft of 27 feet 6 inches (8.4 meters). Her propulsion system consisted of two four-cylinder triple-expansion steam engines, each driving a propeller shaft, developing a total of 23,650 indicated horsepower (17,640 kW), enabling a maximum speed of 23.3 knots (43.2 km/h; 26.8 mph). The ship's boilers included 19 Yarrow water-tube boilers and six cylindrical boilers, providing a range of 7,960 nautical miles (14,740 km; 9,160 miles) at 10 knots. Her main armament comprised six BL 9.2-inch (234 mm) Mark X guns in single Mk V turrets—two on the centerline fore and aft, and four at the corners around the funnels—while secondary armament included four BL 7.5-inch (191 mm) guns in single Mk II turrets amidships. The vessel also carried twenty-six Vickers QF 3-pounder guns and several anti-aircraft guns added during her service, notably a Hotchkiss QF 6-pounder in 1915, later replaced by a 3-inch gun in 1916, along with additional 3-pounders installed amidships. The ship's stability was somewhat compromised due to the added topweight from turreted secondary guns, but her design made her a steady gun platform and seaworthy vessel. Cochrane's service included participation in the Battle of Jutland in 1916, where she was present but remained unengaged. She was part of the 2nd Cruiser Squadron and took part in various deployments, including escorting the Royal Yacht Medina and reinforcing defenses in the Shetland Islands at the outbreak of WWI. Later, she served on the North America and West Indies Station and was based in Murmansk during the Allied intervention in the Russian Civil War, notably ferrying Soviet troops to Pechenga. Her career ended abruptly when she stranded in the Mersey Estuary on 14 November 1918, breaking in two, and was subsequently broken up in situ by June 1919, marking the end of her maritime service.
