Nuclear Deterrent

Statement My Lords, I am sure the whole House will wish to join me in offering sincere condolences to the family and friends of Marine Nigel Mead from 42 Commando Royal Marines, who was killed in Afghanistan on Sunday 15 May. My thoughts are also with the wounded, and I pay tribute to the courage and fortitude with which they face their rehabilitation. With the leave of the House I will now repeat a Statement made in the other place by my right honourable friend the Secretary of State for Defence: ““Mr Speaker, with permission, I would like to make a Statement on our nuclear deterrent programme. The House will be aware that we have been considering the next stage of investment, called initial gate, in the programme to deliver a successor to our current nuclear deterrent. This is the point in the MoD’s procurement cycle at which we decide on broad design parameters, set our plans for detailed system assessment and order any long-lead items that might be required. Taking this action enables us to be sure that we will take the right decisions at the key investment stage, the main gate, which for this submarine programme will be in 2016. I am announcing today that we have approved the initial-gate investment and selected a submarine design that will be powered by a new generation of nuclear propulsion system—the Pressurised Water Reactor 3—that will allow our submarines to deliver our deterrent capability well into the 2060s if required. At this milestone in the project it is useful for me to remind the House of this Government’s policy on the nuclear deterrent. The first duty of any Government is to ensure the security of their people. The nuclear deterrent provides the ultimate guarantee of our national security, and for the past 42 years the Royal Navy has successfully operated continuous deterrent patrols to ensure just that. I pay tribute to the crews and support staff who ensure the continued success of deterrent operations, and I extend that tribute to the families of all those personnel, many of whom are regularly away from home for long periods. We assess that no state currently has both the intent and the capability to threaten the independence or integrity of the UK, but we cannot dismiss the possibility that a major direct nuclear threat to the UK might re-emerge. We simply do not know how the international environment will change in the next few years, let alone the next 50 years. And, as this House concluded in 2007 when it voted on whether the UK should start a programme to renew the deterrent, the time is simply not right to unilaterally do away with it. This is not to say that, if the time is right, we will not move away from nuclear weapons. Our long-term goal remains a world without them and we are doing all we can to counter proliferation, make progress on multilateral disarmament and build trust and confidence with nations across the globe. In this spirit, as part of the value-for-money study, we reviewed carefully how we manage our deterrent programme, and concluded that we could take significant steps to demonstrate our commitment to disarmament by reducing the number of warheads from no more than 48 to no more than 40 carried on each deterrent submarine, consequently to reduce our overall stockpile of nuclear weapons from no more than 225 to no more than 180 in due course, and giving a stronger assurance to non-nuclear weapon states in compliance with the nuclear non-proliferation treaty. The value-for-money study delivered £3 billion of savings and deferrals over the next 10 years. The coalition agreement reflected both parties' commitment to a minimum credible nuclear deterrent, but also the desire of the Liberal Democrats to make the case for alternatives. As Secretary of State for Defence, I am absolutely clear that a minimum nuclear deterrent based on the Trident missile delivery system and continuous at-sea deterrence is right for the United Kingdom and that it should be maintained, and that remains government policy. But to assist the Liberal Democrats in making the case for alternatives, I am also announcing today the initiation of a study to review the costs, feasibility and credibility of alternative systems and postures. The study will be led by officials in the Cabinet Office, overseen by the Minister of State for the Armed Forces. A copy of the terms of reference of the study will be placed in the House of Commons Library. As I have said, the Government have approved the initial gate for the nuclear deterrent successor programme. We have now agreed the broad outline design of the submarine, made some of the design choices, including the propulsion system and the common US/UK missile compartment, and developed the programme of work we need to be ready to start building the first submarine after 2016. We have also agreed the amount of material and parts that we will need to buy in advance of the main investment decision. We expect the next phase of work to cost in the region of £3 billion. This is a significant sum of money, but I am confident that it represents value for money for the taxpayer as every aspect of the programme has been carefully reviewed by the MoD, the Treasury and Cabinet Office officials. It will fund the programme we need to conduct to make sure that we can bring the submarines into service on time. Overall, we assess that the submarine element of the programme will still be within the £11 billion to £14 billion estimate set out in the 2006 White Paper. These figures were quoted at 2006 prices and did not account for inflation; the equivalent today is £20 billion to £25 billion at outturn, but it is important the House recognises that there has been no cost growth in the programme since the House first considered the findings of the White Paper. Between now and main gate we expect to spend around 15 per cent of the total value of the programme. This is entirely consistent with defence procurement guidance. The cost of long-lead items is expected to amount to around £500 million, but it is not true to say that large parts of the build programme will have been completed by main gate. Although we are ordering some of the specialist components, this does not mean that we are locked into any particular strategy before main gate in 2016. I focus for a moment on the matter of nuclear safety. There has been some ill informed comment suggesting that our nuclear propulsion systems are not safe. That is simply not true. All our nuclear propulsion plants meet the stringent safety standards set out by the defence nuclear safety regulator and the Health and Safety Executive. However, given that we are developing a new design of submarine, it is right that we take advantage of the opportunity that affords to advance our policy of seeking continual improvement of nuclear safety. A new propulsion plant allows us to do this, while giving us the opportunity to improve the availability of propulsion systems and lower through-life support costs. I have announced a major step forward in this programme. We have some of the finest submarine-builders in the world, and the approval of the next phase of work in the programme will secure the jobs of the highly skilled and professional workforce already involved in the programme, as well as providing further opportunities for the engineers and apprentices of the future. However, both my department and industry have much to do to deliver the programme to ensure that we continue to maintain the sustainability of the submarine industry, that we improve performance and that we drive down costs through more efficient and inclusive working. I am confident that all sides will respond to that challenge. This is a programme of great national importance so, today, I am placing in the Library of the House a report that sets out in detail the work that has been completed so far, the key decisions that I have presented to the House today, and the work required over the coming months and years. I believe that the decisions we have taken on our nuclear deterrent programme in initial gate are the right decisions for the country and that, as a result, future generations will continue to benefit from the security we have been so fortunate to enjoy””. My Lords, I commend the Statement to the House.
