F35A and F35B Jets

Lord West of Spithead Excerpts

Tuesday 1st July 2025 Lords Chamber

Asked by

[Lord West of Spithead]

To ask His Majesty’s Government whether the recently announced procurement of twelve F35A jets capable of carrying nuclear weapons will affect the planned procurement of F35B jets.

[The Minister of State, Ministry of Defence (Lord Coaker) (Lab)]

I draw noble Lords’ attention, on my noble friend’s very serious point, to the fact that just last week I was in Singapore with the carrier strike group. What a proud moment it was for our country to see the “Prince of Wales” in Singapore harbour at the invitation of the Singapore Government, with F35Bs and helicopters all over it, to see the crew there and to visit the other ships that are part of it. I just wanted to say that but, in answer to my noble friend’s Question, I can confirm that the second procurement phase will consist of 12 F35As and 15 F35Bs, which will enable the stand-up of the third front-line squadron focused on F35Bs. Forty- one of the 48 F35Bs in the first procurement phase have been delivered, with 617 Squadron and 809 Naval Air Squadron both currently deployed on HMS “Prince of Wales” for Operation Highmast. We remain committed to 138 F35s across the life of the programme, and the defence investment programme will examine options on further purchases in the coming months.

[Lord West of Spithead (Lab)]

I thank my noble friend the Minister for his reply, although my question has been rather shredded of various elements by the previous debate. It is worth remembering that 80 years ago as we speak, the British Pacific fleet was leaving the waters around Okinawa, heading towards the Japanese homeland. It consisted of a mere 21 aircraft carriers, four battleships and dozens of destroyers and frigates, which were in the same waters that the “Prince of Wales” is in now. They were under almost continuous attack by kamikazes, which you could argue are the ultimate drone. Whenever we discuss the military, we ought to remember those who have gone before and what they did to enable us to be here.

As for my question, I now have two bits left after everything that has been discussed. The first one is: does my noble friend believe that now might be time for us to review our nuclear doctrine? One could argue that it goes on all the time, but might it be time to do a proper review of our nuclear doctrine? The other one is: I had understood that major investment decisions—and this is one, bearing in mind the costs of having bases ready to take nuclear weapons and all of this sort of thing—were going to be made in the autumn as part of the defence investment plan to check out the national armaments director and the new strategic headquarters. Does the fact that this decision has been made now, without waiting for the autumn, mean that all the decisions from the SDR that we were expecting in the autumn will be taken piecemeal before then?

[Lord Coaker (Lab)]

I thank my noble friend for his questions. On his very serious and important point about those who made the ultimate sacrifice in the Far East, he will be pleased to know that, on my visit to Singapore, I visited the war grave cemetery there, and that when I was in Jakarta a day or two later, I visited the war grave cemetery there and laid a wreath to remember those who had gone before. I think that is really important.

On the issue of the nuclear doctrine, of course one always reflects on these matters but, as it stands, the nuclear doctrine is as it is. The major investment decisions, in terms of the money and the direction of travel, remain the same. It was felt important, given the serious geopolitical challenges that we face and although the number of planes remains the same, that there should be some movement from F35Bs to F35As. It was important that we made that decision at this particular time in the light of the threat that we face.
