HMS Dreadnought (1906) : ウィキペディア英語版 | HMS Dreadnought (1906)
HMS ''Dreadnought'' was a battleship of the Royal Navy that revolutionised naval power. Her entry into service in 1906 represented such a paradigm shift in naval technology that her name came to be associated with an entire generation of battleships, the "dreadnoughts", as well as the class of ships named after her. The generation of ships she made obsolete became known as "pre-dreadnoughts". She was the sixth ship of that name in the Royal Navy. Admiral Sir John "Jacky" Fisher, First Sea Lord of the Board of Admiralty, is credited as the father of ''Dreadnought''. Shortly after he assumed office, he ordered design studies for a battleship armed solely with guns and a speed of . He convened a "Committee on Designs" to evaluate the alternative designs and to assist in the detailed design work. One ancillary benefit of the Committee was that it would shield him and the Admiralty from political charges that they had not consulted leading experts before designing such a radically different battleship. ''Dreadnought'' was the first battleship of her era to have a uniform main battery, rather than having a few large guns complemented by a heavy secondary battery of smaller guns. She was also the first capital ship to be powered by steam turbines, making her the fastest battleship in the world at the time of her completion.〔Sturton, pp. 76–77〕 Her launch helped spark a naval arms race as navies around the world, particularly the German Imperial Navy, rushed to match her in the build-up to World War I.〔 In 1915 ''Dreadnought'' became the only battleship to sink a submarine when she rammed the when it unexpectedly broke the surface after firing a torpedo at another dreadnought.〔 ''Dreadnought'' did not participate in the Battle of Jutland in 1916 as she was being refitted. This was the only time during the war that British dreadnought battleships fired on their German counterparts. Nor did ''Dreadnought'' participate in any of the other World War I naval battles. After the Battle of Jutland she was relegated to coastal defence duties in the English Channel, not rejoining the Grand Fleet until 1918. She was reduced to reserve in 1919 and sold for scrap two years later. ==Genesis==
