Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent progress his Department has made on implementing the Naval Support Integrated Global Network (NSIGN) Programme.

The Naval Support Integrated Global Network (NSIGN) Projects will enable the Ministry of Defence to contract for Submarine and Naval Base services delivered through Clyde and Devonport in March 2026, and for Ships and wider Naval Base services from October 2028.

The NSIGN Programme continues to progress through the Assessment Phase with the NSIGN (Submarines) Project Outline Business Case (OBC) being approved in April 2025. Work is progressing with the NSIGN(Ships) and NSIGN (Naval Bases) Projects, both of which will be seeking OBC approval in Autumn 2025.
