Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the answer of 8 September 2026 to question 22871 on NATO, by when will he publish the NATO Interoperability Roadmap.

The Government is committed to a NATO-first approach and to strengthening interoperability across the Alliance. The Strategic Defence Review directed Defence to establish a roadmap for delivering deeper interoperability with NATO Allies and for leading the way on shared approaches and standards by January 2026.

In response, the UK's NATO Interoperability Roadmap was completed in January 2026 and approved by the then Minister for the Armed Forces, Al Carns MP. Implementation commenced immediately thereafter.

The Roadmap is aligned with NATO's Interoperability Plan. It provides Defence with a framework to improve the Armed Forces' ability to operate effectively alongside NATO Allies through common standards, digital integration, training, exercises and capability development.

The UK’s NATO Interoperability Roadmap contains information relating to Defence planning and capability development and will therefore not be published. The House may be assured, however, that the SDR's "NATO First" principle remains central to both the Roadmap and its implementation.
