Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the Government press release entitled UK to purchase F-35As and join NATO mission as Government steps up national security and delivers defence dividend, published on 24 June 2025, when his Department expects the new F-35As to be certified to use nuclear weapons.

The nuclear weapons allocated to the NATO nuclear mission are US weapons and the US needs to certify that any aircraft or personnel allocated to the mission are appropriately trained and equipped. We will continue to work closely with the US on the timeline to deliver this capability for the UK, including certification.
