Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what discussions the UK has had with NATO allies on the sustainability of air defence ammunition stocks in the event of prolonged drone-based conflict.

The UK has regular and ongoing discussions with NATO allies on the sustainability of air defence ammunition stocks. This includes through the NATO Conference National Armament Directors (CNAD), which held an extraordinary meeting on air and missile defence on 23 January 2025, and the NATO Defence Industrial Production Board, which is currently addressing how we increase industrial capacity in Surface-Based Air and Missile Defence. The UK is also encouraging allies to consolidate future buys of air defence ammunition and support increased production capacity through our NATO Multinational Procurement Initiatives and NATO’s Reoccurring Process for Aggregating Demand Signal (REPEAD). The UK remains committed to working closely with NATO allies to ensure the sustainability of air defence ammunition stocks and to address the challenges posed by evolving threats, including drone-based warfare. The Government will continue to prioritise this issue and work with Allies to ensure that NATO remains prepared to respond to current and future security challenges.
