The ‘most advanced boats of their kind’
The HMS Dreadnought will be a nuclear-powered and armed submarine. According to a Royal Navy press release, the submarine will displace “17,000 tonnes, [will be] the length of 14 buses and [will have] a crew of around 130.”
This will make HMS Dreadnoughts “the most advanced boats of their kind in service anywhere.”
The nuclear submarine will feature a Rolls-Royce PWR3 nuclear reactor paired with an advanced pump-jet system. It will be armed with 12 Trident II D5 SLBMs with a range of about 7,500 miles (12,000 km). The nuclear submarine will have the capacity to carry as many as 144 nuclear warheads.
