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 armament 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.Her launch helped spark a naval arms race as navies around the world, particularly the Imperial German Navy, rushed to match it in the build-up to the First World War.
Although designed to engage enemy battleships, her only significant action was the ramming and sinking of German submarine SM U-29; thus she became the only battleship confirmed to have sunk a submarine. Dreadnought did not participate in the Battle of Jutland in 1916 as she was being refitted. Nor did Dreadnought participate in any of the other First World War naval battles. In May 1916 she was relegated to coastal defence duties in the English Channel, before rejoining the Grand Fleet in 1918. The ship was reduced to reserve in 1919 and sold for scrap two years later.Photograph credit: United States Navy photograph; restored by Adam Cuerden
