Nuclear Deterrent

Lord Campbell of Pittenweem Excerpts

Wednesday 18th May 2011 Commons Chamber

[Dr Fox]

I shall do my best to answer the long list of questions that the right hon. Gentleman asked. I shall check Hansard, and if I have missed any I shall write to him with further details.

May I thank the right hon. Gentleman for the Opposition’s support for the principle of this policy? Cross-party support adds greatly to the credibility of our deterrence policy, which is an essential part of the protection of our country. He rightly says that the major proliferation risk at the moment comes from North Korea and Iran. We do not know whether other countries will join in that so, as he says, it is entirely prudent to retain a minimum, independent, credible nuclear deterrent for the United Kingdom.

The right hon. Gentleman asked a number of specific questions about costs. The costs of the various items were set out in the 2006 White Paper, when they were broadly split into: £11 billion to £14 billion for the submarine; £2 billion to £3 billion for the warhead; and £2 billion to £3 billion for infrastructure. We believe that those costs are still contained in the programme itself. He asked specifically about long lead items, on which, as I said in my statement, approximately £500 million will be spent. They include: the specialised high-grade steel; the main boat systems, such as the computer systems, hydraulic systems and atmospheric systems, the generators and the communications systems; and specialist components, including steam generators and test rigs for the propulsion plants.

On our wider international co-operation, we continue to work, as we set out in our treaty with France, on the capabilities required constantly to maintain the safety of our warheads. There are no plans for collaboration on deployment of a deterrent that goes beyond the treaty that has been signed. Agreement with the United States on the major parameters of the jointly developed common missile compartment design, which will be capable of carrying the Trident D5 missiles and any replacement once the D5 reaches the end of its life in the 2040s, has been a major part of our cost containment during the process.

The right hon. Gentleman asked about the overall costs of the programme. As I said, £3 billion of those will fall between now and 2016. The costs for the years that fall within the current comprehensive spending review are met by the current defence budget settlement. He asked about the life and costs of the Vanguard class submarines. Our assessment when we undertook the value-for-money study was that we could extend Vanguard’s life to 2028 without having huge additional maintenance and upgrade costs, and while preserving our continuous at-sea deterrent—CASD. To go beyond 2028 would almost certainly have huge cost implications and might have implications for CASD that we are not willing to undertake. Those were the reasons we took the overall decision, and I hope that I have answered the right hon. Gentleman’s specific questions.

[Sir Menzies Campbell (North East Fife) (LD)]

My right hon. Friend is well known for his independence and openness of mind, as was shown by his recently published correspondence with the Prime Minister. May we take it that the conclusions of the study to which he has referred will be published? Given that independence of mind, may we also take it that if the study produces credible procurement and policy alternatives, he will take proper account of them?
