Devonport Dockyard: Repairs and Maintenance

Question: To ask the Secretary of State for Defence, what recent progress his Department has made on implementing the Submarine Waterfront Infrastructure Future programme.

Answer: The Submarine Waterfront Infrastructure Future (SWIF) programme will deliver substantial infrastructure upgrades at HM Naval Base Devonport, as part of a wider significant investment programme to restore capacity and resilience to support the maintenance of our submarine fleet. The design phase of the SWIF programme is coming to a close and we are now starting the construction stage. This comes on the back of the restoration of 9 Dock to undertake submarine deep maintenance and 15 Dock to enable operational maintenance.
