The Dreadnought programme is about the design, development and manufacture of four new Dreadnought class ballistic missile submarines.
When they enter service in the early 2030s, replacing the Vanguard Class, they will be the largest submarines ever operated by the Royal Navy.
The submarines will be built in 16 units, grouped into three ‘mega units’ (Aft, Mid and Forward) in order to optimise the overall build timeframe.
Each submarine will be built by BAE Systems Submarines in Barrow-in-Furness and their nuclear propulsion systems will be built by Rolls Royce Submarines in Derby.
The build phase for all four submarines will take approximately 20 years.
The Dreadnought Class – Key facts
Each submarine will be 153.6 metres long – the approximate length of three Olympic swimming pools.
Innovative new lighting will allow the crew to simulate night and day – another first for a Royal Navy submarine.
130 crew, including 3 chefs and one doctor
The doctor on board each of the submarines will work from a designated sick bay. Here they’ll conduct routine check-ups, dispense medicines and could care for a major casualty if needed.
Each submarine will have modern gym facilities for the crew, including exercise bikes, rowers, weights, benches a running machine and cross trainer.
This is the first Royal Navy submarine to be built with separate female crew quarters, toilets and washing facilities.
