HMS Dreadnought (Fear Nothing) commissioned in 1906, was a revolutionary ship which was the first all big gun warship, consisting of ten 12-inch guns in five turrets, first ship to be powered with oil powered steam turbines which made it the fastest in the world at the time. She was the pride of First Sea Lord Sir John "Jackie" Fisher who was responsible for her construction in 1905 and she is the only battleship to have ever sunk a submarine when in in World War 1 she rammed the German Submarine U-29. She was scrapped on May 9, 1921. There is still a Dreadnought type battleship in existence, the USS Texas (BB-35) which is the only warship which served in World War 1 and World War 2, and she is being refurbished as a museum ship.
