Warships Military
The dreadnought was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's Dreadnought, had such an impact when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts," and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany.
Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armor, and propulsion throughout the dreadnought era. Within five years, new battleships outclassed Dreadnought herself. These more powerful vessels were known as "super-dreadnoughts". Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued serving throughout World War II.
While dreadnought-building consumed vast resources in the early 20th century, there was only one battle between large dreadnought fleets. At the Battle of Jutland, the British and German navies clashed with no decisive result. The term "dreadnought" gradually dropped from use after World War I, especially after the Washington Naval Treaty, as virtually all remaining battleships shared dreadnought characteristics; it can also be used to describe battlecruisers, the other type of ship resulting from the dreadnought revolution.
The designers of dreadnoughts sought to provide as much protection, speed, and firepower as possible in a ship of a realistic size and cost. The hallmark of dreadnought battleships was an "all-big-gun" armament, but they also had heavy armour concentrated mainly in a thick belt at the waterline and in one or more armoured decks. Secondary armament, fire control, command equipment, and protection against torpedoes also had to be crammed into the hull.
The inevitable consequence of demands for ever greater speed, striking power, and endurance meant that displacement, and hence cost, of dreadnoughts tended to increase. The Washington Naval Treaty of 1922 imposed a limit of 35,000 tons on the displacement of capital ships. In subsequent years treaty battleships were commissioned to build up to this limit. Japan's decision to leave the Treaty in the 1930s, and the arrival of the Second World War, eventually made this limit irrelevant. More details
