Devonport Dockyard: Infrastructure
The question
To ask the Secretary of State for Defence, with reference to the Defence Investment Plan, published on 30 June 2026, page 30, what progress has he made in delivering the Devonport Infrastructure Programme.
Answered by Ministry of Defence
The Devonport Infrastructure Programme is making significant progress in modernising facilities at His Majesty’s Naval Base Devonport to reinforce its role as the Royal Navy’s centre for submarine deep maintenance. Upgrades to docking and waterfront infrastructure have already enabled Astute Class submarines to undertake maintenance activities in Devonport, with further improvements continuing across the site.
The programme is also delivering additional support for current and future submarine classes, the recommencement of the submarine defueling programme, and new maintenance berthing capacity, strengthening the Royal Navy’s overall warfighting readiness.
We are currently reviewing opportunities to accelerate work following the nuclear regulatory review and we continue to press for the earliest possible delivery of the projects.
