Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 15 September 2025 to Question 75028 on France: Military Alliances, what his Department's policy on the procurement of (a) low-yield and (b) air-launched nuclear weapons to use on the battlefield.

As set out in the Strategic Defence Review. The UK will continue to rely on continuous at-sea deterrence delivered by our four Vanguard Class submarines, equipped with Trident II D5 missiles, armed with UK sovereign nuclear warheads. The UK’s replacement warhead programme will deliver the A21/Mk7 warhead to replace the in service Mk4A. The SDR also sets out our ambition to join NATO’s nuclear mission using US sovereign weaponry.
