HMS Tiger was a battlecruiser of the Royal Navy and the eleventh ship to bear that name. She was built by John Brown and Company of Clydebank, Scotland, and launched in 1913. Tiger was the most heavily armoured battlecruiser of the Royal Navy at the start of the First World War, but was not yet ready for service.
Art Me & Boravejder 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 Queen Elizabeth class, but there is no record of any additional battlecruiser being provided for in any naval estimates before 1914.[3][4][5] Tiger had an overall length of 704 feet (214.6 m), a beam of 90 feet 6 inches (27.6 m), and a mean draught of 32 feet 5 inches (9.88 m) at deep load. She normally displaced 28,430 long tons (28,890 t) and 33,260 long tons (33,790 t) at deep load. Although Tiger was only 4 feet (1.2 m) longer and 1 foot 5.5 inches (0.4 m) wider than the previous battlecruiser, Queen Mary, she displaced almost 2,000 long tons (2,000 t) more than the older ship. She had a metacentric height of 6.1 feet (1.9 m) at deep load.[6] In September 1914, her complement consisted of 1,112 officers and ratings; in April 1918, they totalled 1,459.
