When HMS Dreadnought was commissioned into the Royal Navy in 1906 this revolutionary new class of big-gun iron-clad warship immediately changed the face of naval warfare, rendering all other battleships worldwide obsolete. The Admiralty realised that as soon as the ship was revealed to the global naval community Britain would be a in race to stay ahead, and so the first dreadnoughts were built in record time. While there were those who regarded the vessel as a triumphant revolution in naval design, the dreadnought initially had its critics, including those who thought its slower, heavier guns left it vulnerable to the secondary armament of other warships. Nevertheless, other countries, notably Germany, and the United States soon began to lay down dreadnoughts. The culmination of this arms race would be the confrontation of the British and German fleets at the Battle of Jutland in May 1916 - the greatest clash of naval firepower in history. This book gives detailed insights into the design, operation and combat history of these incredible vessels.
