Devonport’s First Battleship
128 years ago on 15th February, in Queen Victoria’s Diamond Jubilee year of 1897, HMS Ocean, the first Battleship to be built at Devonport, was laid down. In order to build this behemoth of almost 14,000 tons and 390ft long, No 3 slip had to be extended and its old roof taken off. Instructions were given that she be completed within 20 months, in an unofficial shipbuilding race AKA “The Canopus Stakes”, between Portsmouth and Chatham building Ocean’s sisters, Canopus and Goliath respectively. Unfortunately Devonport suffered a setback when some frames failed. This caused 90ft of the fore part of the ship, from stem to turret, to collapse. An investigation showed the cause to be a labourer who had removed some bolts, without understanding their purpose, to assist him move some plates through the ship. Further delays occurred owing to shortages of drillers and riveters, a strike, and a failure to deliver principal castings, such stern post and shaft brackets, on time. Consequently she remained on the slip for 17 months, twice as long as expected and was not completed until February 1900, a total of 36 months from start to finish.
Ocean initially commissioned for the Mediterranean, but sailed for China in 1901 as a consequence of the Boxer Rebellion. She returned to Devonport in August 1905. 1906-1913 saw her mainly in the Home Fleet, with a spell back in the Mediterranean. In 1914, she was sent to the East Indies, but with the outbreak of war, she moved to operations in the Persian Gulf, before being sent to the Dardanelles in 1915. On the 18th March, Ocean attempted to tow the battleship Irresistible, crippled by a mine, when the tow was abandoned, she also struck a mine and was hit by shore guns. Her crew were taken off by destroyers and she sank in Morto Bay. A Pre-Dreadnought battleship, Ocean’s vital statistics were as follows:
Displacement: 12,950t, Length: 390ft, Speed: 18kn, Complement: 750, Armament: 4x 12” and 12x 6” guns.
Compare the above with Devonport’s most famous battleship, completed only 15 years after Ocean, HMS Warspite, which displaced 33,000t and was armed with 8x 15” guns and could touch 25kn! That’s progress.
