This Government keeps the UK’s nuclear posture under constant review considering the international security environment and the actions of potential adversaries. Our nuclear deterrent can respond to any emerging crises.

The recent announcement that the UK is acquiring 12 nuclear capable F35-A fighter jets, and will join the NATO nuclear mission, is not a decision to acquire a second sovereign delivery system. It complements Continuous At Sea Deterrence, our operationally independent, sovereign deterrent, which remains the ultimate guarantor of our security.
