UK Weapons Systems

Lord Reid of Cardowan Excerpts

Tuesday 1st July 2025 Lords Chamber

[Lord Coaker (Lab)]

Let us deal with this, and I apologise to the House if this takes some time. The strategic deterrent, CASD, remains, as we have always had it, operationally independent and a UK weapon. As for the 12 F35As that the Government have announced, that forms part of NATO’s nuclear mission. The F35As are UK jets and they are dual-capable aircraft, so they can be used normally or, in a particular crisis or a particular sense in which we felt and NATO felt that they should be used, they would become part of the nuclear mission. At that time, they would be armed with American nuclear missiles.

Of course, that means that the authorisation of the use of those missiles remains US-controlled, because, in the same way that we control our UK nuclear weapons, US nuclear weapons remain subject to US approval. The point I was making to the noble Lord is important. Of course, the authorisation for the use of those weapons within the context of a NATO mission has to be agreed by the NATO planning group and the UK is part of that. In that sense, the Prime Minister would have to authorise those UK planes being used to deliver that nuclear capability. I hope that is clear to the House and to the noble Baroness, because it is an important point for us to make with respect to the nuclear shield and the nuclear capability that this country has, and how it will work in practice.

[Lord Reid of Cardowan (Lab)]

My Lords, I declare an interest in that, along with my noble friend Lord Robertson, we got rid of gravity nuclear bombs back in 1997. That was in a particular context, and I fully accept that the world has changed, so I have no objection to now maintaining or restoring that capacity. However, since we are getting the F35As, what is the implication of that for any offset arrangement in the previously considered demand for F35Bs?

[Lord Coaker (Lab)]

I am going to either pass or fail this exam. As it stands, we have 41 F35Bs, and by March 2026 we should have 48. That is what is called the first procurement phase. The F35As will be brought within the second procurement phase, which will take the whole F35 programme from 48 to 75. That is an additional 27 aircraft, of which 12 will be F35As and 15 will be F35Bs. I will give a further answer in response to the noble Lord, Lord West, by saying that they will form part of an operational group. The F35As will go to that group, which will free up the F35Bs that are currently doing that training exercise with them. So the carrier and others will always have the full complement of F35Bs that they need.
