HMS Dreadnaught, battleship with innovative design that made all other battleships obsolete and forced all the world's powers to build their own version that would be called dreadnaughts. Although built with specific aim to engage enemy surface capital ship, HMS Dreadnought saw relatively little action in WW1, except in case of ramming German submarine U-29 in 1915, becoming the only battleship to do so. The ship was decommissioned and sold fro scrap in 1921.#historyonleo #onthisday On February 10th 1906 British Royal Navy launches
