The programme will eventually deliver four submarines to replace the current Vanguard class of submarines, meaning the UK will be able to have at least one submarine at sea at all times. Yet another one to be named HMS Dreadnought, the first in class is in development by BAE Systems with support from Rolls-Royce. The ship will also be the first to simulate night and day schedules through lighting to make the transition from surface to submersion easier for the crew. In comparison, the Royal Navy’s new Dreadnought class of nuclear deterrent carrying submarines will be the largest ever built for service, at 150m long with a displacement of more than 17,000 tonnes. The SM U-21 a German submarine commissioned shortly before the outbreak of the war was 65m long, could travel 50m, below the surface, and had a displacement of 824 tonnes when submerged. Submarines have come a long way since they revolutionised underwater warfare in the WWI era. The new Dreadnought and the nuclear deterrent Nautilus broke all speed and distance records of its generation and in 1958 was the first watercraft to travel under the North Pole. Acquiring US nuclear technology rapidly sped up the development of the HMS Dreadnought, which entered service in 1963.īy the time the submarine had been completed, Rolls -Royce and its partners had generated their own nuclear propulsion system, paving the way for the UK’s next nuclear submarine to be built completely in the UK.Īlthough the original Dreadnought submarine was the first British nuclear-powered boat, the USS Nautilus was the first nuclear powered submarine to enter service in 1955. The hull and offensive systems on the submarine were designed in the UK but the boat’s propulsion system was supplied by the US. In the 1960s, the first British nuclear-powered submarine, and the first submarine to bear the name Dreadnought, was born from a US and UK defence partnership. HMS Voracious was one of the British submarines built for the Royal Navy during WWI Cold War era: nuclear-powered submarines Since then, no other submarine has done the same. Venturer’s crew calculated the path of the adversarial submarine and launched torpedoes in a fan pattern, meaning that when the German U-boat turned, its crew unwittingly steered into the line of fire. After learning it was being followed the U-864 conducted evasive manoeuvres in order to escape the British sub. In 1945, the UK’s HMS Venturer spotted the German Navy submarine U-864. WWII also saw the first and only sinking of a submerged submarine by another submarine using manual calculations that formed the basis of modern targeting computers.

In other theatres the Japanese Navy pioneered the use of small-scale submarines, which were intended to defend the home islands from invasion while the Royal Navy used the boats to blockade Axis-occupied Europe. Crewed by 39 sailors, the boats could travel around 9,000 miles from port. Most of them were Type 93 class submarines, carrying 16 torpedoes as well deck guns to guard the ships when they surfaced. The U-21 was said to have ventured deep into UK waters, reaching Forth Bridge close to the UK’s naval base in Rosyth.īy the end of war, Germany had built over 370 U-boats, sending the vessels out into the Atlantic to interfere with shipping. The incident also showed how deep into enemy waters submarines could penetrate. This belief was swiftly shattered when, just months into the war, the German SM U-21 sank the scout cruiser HMS Pathfinder. As a result, Germany all but gave up on attempting to confront the Royal Navy, instead adopting submarine warfare as a means of striking back.Īt the onset of the war, submarine development also shook up the status quo of naval combat: commanders of the time believed that no submarine could sink a capital ship.

Huge at the time, the British fleet effectively cut off all Germany’s maritime trade, blockading the North Sea and English Channel. In the years preceding the war, Germany massively expanded its undersea fleet, largely in an effort to counteract the vast naval power of the UK’s Royal Navy.
