HMS Monarch (1911)

HMS Monarch was the second of four Orion-class dreadnought battleships built for the Royal Navy and the third ship of her name. Armstrong Whitworth laid her down at its Elswick shipyard on 1 April 1910, launched her on 30 March 1911 and completed her on 31 March 1912. Two sets of Parsons direct-drive steam turbines, fed by 18 Yarrow boilers, were rated at 27,000 shaft horsepower, and on her trials on 9 December 1911 she reached 21.9 knots. She spent the bulk of her career in the Home and Grand Fleets and took part in the Battle of Jutland in May 1916. After the Grand Fleet was dissolved in 1919 she went to the Reserve Fleet, was listed for disposal in 1922 and was hulked as a stationary training ship. In late 1923 she became a target ship, used to test the blast effects of large bombs against a replica of the Nelson-class underwater protection, and she was sunk in early 1925.
