Question to the Ministry of Defence:

To ask the Secretary of State for Defence, when contracts (a) will be signed with Rolls Royce for the reactors for the Dreadnought ballistic missile submarines and (b) need to be delivered by so as not to delay the overall Dreadnought-class build programme.

As referenced in the 2019 Annual Update to Parliament on the UK's Future Nuclear Deterrent, the contract to deliver the nuclear propulsion power plants for all four Dreadnought class submarines was awarded to Rolls-Royce in May 2019. Equipment deliveries to the BAE Systems' Barrow-in-Furness shipyard are ongoing and will support the entry to service of the First of Class in the early 2030s.
