Oral question asked in the House of Commons, by Lord Harper (Conservative). It was answered on Monday, 30 March 2009 on behalf of the Ministry of Defence.

Trident

Question: The opposition of the hon. Member for Islington, North (Jeremy Corbyn) to this policy is well known. The Secretary of State has made it very clear that renewing our current system is within the terms of the NPT, and that we are able to do that. He, like us, supports a multilateral disarmament approach. Can he give the House any idea about the time scales, not only for the development of the submarines, but about how well they are meshed in with the development of the warhead system?

Answer: We have made it clear that we believe that the replacements for the Vanguard class submarines would be needed for 2024. An extensive time is needed to design, construct, build, test and operate the new submarines, which potentially will be very capable, and I think that that will take us up to 2024. As I said in my answer to my hon. Friend the Member for Islington, North (Jeremy Corbyn), a decision to renew the warhead will have to be taken by the House of Commons during the next Parliament. I believe that the programme that we set out in the 2006 White Paper is coherent and joined up.
