AUKUS: Nuclear Submarines

The question

To ask the Secretary of State for Defence, with reference to the press release entitled Cutting-edge underwater tech for AUKUS forces to be developed through landmark partnership, published on 30 May 2026, from what month and year will the first UK deployment of an Astute-class submarine to Submarine Rotational Force-West take place.

Answered by Luke Pollard

Submarine Rotational Force-West is on track to be established in 2027, as confirmed in the joint AUKUS Defence Ministers’ statement of 30 May 2026. The UK has reaffirmed its commitment to maintain a rotational presence as part of Submarine Rotational Force-West. As I am certain the hon. Member will know already the specific scheduling of individual submarine deployments is not published, as to do so could prejudice operational security.
