Trident Submarines

Question

To ask the Secretary of State for Defence, what steps have been taken to consider the successor to Dreadnought.

Answer

I refer the hon. Member to the answer I gave to Question 15525 from the hon. Member for Huntingdon on 10 July 2026:

As announced in the Defence Investment Plan, this Government will invest over £20 billion more in the Defence Nuclear Enterprise over the next four years than the previous four years to modernise and sustain our nuclear deterrent, the cornerstone of our national security. This will fund our new deterrent submarines and warheads, establish a nuclear fuels programme, start defining the Dreadnought successor, and upgrade our infrastructure across the defence nuclear estate. This will allow us to meet the Government’s commitment to start to define the requirement for the post-Dreadnought strategic deterrent within this Parliament.
