Trident Renewal

No, because that would imply that we were in favour of a full-scale, like-for-like replacement of the Trident programme. [Interruption.] If one is going to be pedantic, the motion refers to a missile system that is not due for replacement for some years. In fact, what needs to be decided in the next year or so is whether we shall build new submarines. I think we should, but if we make such an investment, it is essential that the submarines are capable of performing other functions. I do not believe that it makes any sense whatever for us to sail the high seas 24/7, waving weapons of mass destruction at the rest of the world, because we thought it was necessary in 1980 or because we would be left looking embarrassed if we did not make that £30 billion investment.

The Defence Secretary seemed to suggest that to adopt any deployment posture other than continuous at-sea deterrence was somehow risible and laughable, but many sensible studies by serious people have looked at a ladder of different postures for the UK to take. My belief is that we should for the time being retain the components of a nuclear deterrent—the warhead, and the ability to look after it; the missile, and the arrangement with the Americans; and the submarines capable of firing a nuclear weapon—and maintain a highly skilled work force that is regularly exercised in how to put back together the deterrent’s components. NATO air-based nuclear systems in eastern Europe operate on the same basis of a well exercised drill to put the pieces of the deterrent together if it is thought necessary.
