Insider: The British navy is teaming up with the US to build a new ‘Dreadnought’ for a totally different battle at sea 

* The British Royal Navy is building a new class of nuclear-powered ballistic-missile submarines. 

* The British subs will have the same missile compartment as the US Navy’s new missile subs. 

* The name of the new subs recalls the first Dreadnought, a battleship that redefined naval warfare. 

In 1906 the British Royal Navy commissioned HMS Dreadnought, a battleship that changed how surface warships were designed and sparked a naval arms race. 

Armed with five turrets bearing twin 12-inch guns and featuring new technologies like steam turbines and electronic fire-control equipment, HMS Dreadnought became the standard on which future battleships were based and separated the “pre-dreadnought” and “dreadnought” eras. 

 Long after the battleship’s reign came to an end, the name Dreadnought is still a defining one. The Royal Navy’s first nuclear-powered submarine, in service from 1963 to 1980, was also called HMS Dreadnought.
