PARLIAMENTARY WRITTEN QUESTION
(24 February 2026)

To ask the Secretary of State for Defence, what estimate he has made of the number of F-35As that need to be procured to undertake training for the wider UK F-35 fleet and perform the tactical nuclear delivery mission.

Asked by:
Luke Akehurst (Labour)

The United Kingdom is purchasing at least 12 F-35A aircraft. The aircraft will allow the UK to participate in NATO's Dual Capable Aircraft (DCA) nuclear mission. The nuclear weapons allocated to the NATO DCA nuclear mission are United States (US) nuclear weapons and the US retains control and custody over them.

NATO’s 2022 Strategic Concept states that the strategic nuclear forces of the Alliance, particularly those of the US, are the supreme guarantee of the security of the Alliance.

The Government has no plans to expand the UK nuclear deterrent beyond our existing submarine-based system but continues to keep its nuclear posture under constant review in light of the international security environment and the actions of potential adversaries.
