Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the answer of 16 October 2026 to question 31384 on Air Force: Command and Control, what plans he has to modernise the UK Air Surveillance and Control System following the cancellation of Project Guardian UK Version 2.

The Royal Air Force continues to modernise its Air Surveillance and Control System capability following the decision not to proceed with Project GUARDIAN UK Version 2. GUARDIAN Version 1 remains in operational service and continues to be supported, while an alternative in-service system is being used to provide the tactical data-link capability that represented a significant element of the planned UK Version 2 enhancement.

The Ministry of Defence continues to assess the longer-term evolution of Air Command and Control capability through its wider force development and investment planning, informed by operational requirements, and Defence priorities.
