It will use the Rolls-Royce PWR3 nuclear reactor, a US design that is said to be simpler and safer than the PWR2 nuclear reactor on the Vanguard class, while also having a longer lifespan and lower maintenance requirements. It will be larger than the previous class, with a length of around 153.6m and a total displacement of 17,200t. The new Dreadnought class, built by BAE Systems, is expected to replace the existing Vanguard class within the Royal Navy. ![]()
