HMS Tiger was a battlecruiser built for the Royal Navy during the 1910s. The ship was the most heavily armoured British battlecruiser at the start of the First World War in 1914, but was not yet ready for service. The ship was assigned to the 1st Battlecruiser Squadron (1st BCS) for the duration of the war and participated in the Battle of Dogger Bank in early 1915, though she was still shaking down and did not perform well. Tiger next participated in the Battle of Jutland in 1916, where she was only lightly damaged despite suffering many hits by German shells. Apart from providing distant cover during the Second Battle of Heligoland Bight in 1917, she spent the rest of the war on uneventful patrols in the North Sea. The ship was the oldest battlecruiser retained by the Royal Navy after the tonnage limits of the Washington Naval Treaty came into effect in 1922. She became a gunnery training ship in 1924 and then joined the Battlecruiser Squadron in 1929 when its flagship, , underwent a lengthy refit. Upon Hoods return to service in 1931, Tiger was decommissioned and sold for scrap in 1932 in accordance with the terms of the London Naval Treaty of 1930. In his book, The Price of Admiralty, British military historian John Keegan described her as "certainly the most beautiful warship in the world then, and perhaps ever[.]" Design and description Tiger was the sole battlecruiser authorised in the 1911–12 Naval Programme. According to naval historian Siegfried Breyer, a sister ship named Leopard was considered in the 1912–13 Programme and deferred until 1914 as a sixth member of the , but there is no record of any additional battlecruiser being provided for in any naval estimates before 1914. Tiger had an overall length of , a beam of , and a mean draught of at deep load. She normally displaced and at deep load. Although Tiger was only longer and wider than the previous battlecruiser, , she displaced almost more than the older ship. She had a metacentric height of at deep load. In September 1914, her complement consisted of 1,112 officers and ratings; in April 1918, they totalled 1,459. Propulsion Tiger had two paired sets of Brown-Curtis direct-drive steam turbines housed in separate engine-rooms. Each set consisted of high-pressure ahead and astern turbines driving an outboard shaft and low-pressure ahead and astern turbines, housed
