Scottish Referendum (Trident)

Debate between Lord Robathan and Pete Wishart

Thursday 7th March 2013 Westminster Hall

[Pete Wishart]

The Minister says that he is interested in multilateral disarmament, but why are the UK Government perhaps the only Government in the world who are investing in unilateral nuclear rearmament, with Trident renewal?

[Mr Robathan]

The hon. Gentleman, if I might say so, reveals a certain ignorance, as the point is that weaponry has to be kept up to date. It is rather like saying, “Could we not use a one-rupee jezail when fighting in Afghanistan?” I am afraid that those were the days of Kipling, and while the Afghans may have been very accurate, we prefer to use modern weaponry.

The UK has an excellent record in fulfilling its disarmament obligations—as the hon. Member for West Dunbartonshire (Gemma Doyle) said, in relation to the previous Government—under the nuclear non-proliferation treaty, as demonstrated by the latest round of stockpile reductions that we announced in the strategic defence and security review. We probably have the smallest nuclear force of the recognised nuclear weapon states and, uniquely, the UK relies on a single platform, a single weapon system and single warhead design for the delivery of its nuclear deterrent.

However, we continue to work to create a safer and more stable world in which the UK and others can relinquish their nuclear weapons, but we are not there yet. Therefore, nuclear arsenals remain, as does the danger of further proliferation, especially in regions of instability and tension, so we believe that a nuclear deterrent is likely to remain an important element of our national security. Given the uncertainties of the international environment, it would be folly to pursue a policy of unilateral nuclear disarmament. As President Obama said in Prague in 2009, the threat of nuclear war has gone down, but the threat of nuclear attack has gone up.

The UK’s nuclear weapon capability is designed to deter and thereby prevent blackmail and acts of aggression against our vital interests that cannot be countered by other means. It also supports collective security, through NATO, for the Euro-Atlantic area. The UK Government have thus committed to maintain the strategic nuclear deterrent and to continue with the programme to renew it as debated and approved by a significant majority in Parliament in March 2007.

The Government’s policy is that the Vanguard class submarines will be replaced at the end of their lives, in the late 2020s and early 2030s, by a successor submarine, again carrying the Trident missile, subject to main gate investment approval due in 2016. The Government are committed to continuous at-sea deterrence. In times of tensions or crisis, such a posture neither escalates nor de-escalates matters and maximises political freedom of manoeuvre. A submarine-launched ballistic missile system offers invulnerability, range and endurance. All promote the credibility of that deterrent and provide the ultimate safeguard for our national security. I pay tribute to the crews of our submarines and their families, and all the men and women, both military and civilian—including at Faslane—engaged in Operation Relentless, our country’s most enduring current operation, which has been in place for nearly 45 years. I thank them—Scots, English, Irish and Welsh—for their unwavering dedication.

The UK Government’s position on the referendum on Scottish separation is clear: Scotland benefits from being part of the UK and the UK benefits from having Scotland within it. Scotland has played an indispensable role in the development and history of the multi-nation UK. As a result, the UK has developed and flourished, and its constitution, laws and institutions underpin one of the most successful partnerships of nations in history.

If the result of the referendum on Scottish separation were to lead to the current situation being challenged, other options would have to be considered. It would be an enormous challenge to reproduce the facilities that we have at Faslane elsewhere, as we have heard, and any alternative solution would come at huge cost. It is impossible to estimate how much that would be, as it would depend on many factors, including time scales and the precise scope of the facilities that might be required, but it would cost billions of pounds and take many years.

Let me now make this point about Her Majesty’s Naval Base Clyde. The hon. Member for West Dunbartonshire (Gemma Doyle) represents—[Interruption]. A constituency not far away; the hon. Member for Argyll and Bute (Mr Reid) does indeed represent Clyde itself, and Helensburgh, where I went last year. Her Majesty’s Naval Base Clyde underwent a significant investment programme to prepare it for the introduction of the Vanguard-class submarines and the Trident missile system. That programme cost in the region of £3.5 billion at today’s prices, and that built on decades of investment in the base infrastructure and associated housing.

In April 1963, the Civil Lord of the Admiralty, Ian Orr-Ewing, whom I remember and who died only about 15 years ago, informed the House that the operating base for the planned fleet of Resolution-class Polaris ballistic missile submarines needed to be near deep water, to offer easy navigational access and to be a short distance by sea from the associated armament depot. He informed the House that it had been decided that Faslane was the area that was operationally most suitable for the basing of the submarine fleet. My hon. Friend the Member for North Devon (Sir Nick Harvey) pointed out that it is a perfect site. In this varied United Kingdom, we do not have a better site.

That decision was reviewed in the early 1980s, alongside the decision to introduce the Vanguard-class submarines. It was concluded that the Clyde continued to offer the best location. Nothing has happened since to alter that conclusion. Indeed, the Clyde has been chosen as the submarine centre of specialisation, and all our submarines will be based there by the end of this decade, which brings the additional benefits to the region that have been mentioned.

We have mentioned employment at Her Majesty’s Naval Base Clyde, but I now return to that, because it is the largest employment site in Scotland. The base is a major source of employment for highly skilled workers and a significant contributor to the local economy. The rise in the number of jobs during the next decade accompanies the move to base all royal naval submarines on the Clyde to achieve economies of scale and the greater effectiveness of collocation. That symbiosis of a submarine centre of specialisation and associated contractor and base support is a matter of pride, I would have thought, for the UK, for Faslane and for Scotland.

As the collocation benefits would be required in any alternative location, there would be no question but that the entirety of the submarine enterprise on the Clyde would be relocated if the nuclear deterrent force had to move. It is for those who demand the withdrawal of the Vanguard-class submarines from Faslane to explain how the quality and quantity of employment in the region would be matched if the enterprise had to be relocated.

As the UK Government have no plans to disarm unilaterally, there would inevitably be significant time and cost implications if an independent Scottish Government demanded the withdrawal of the UK deterrent. For reasons that I have already described, the UK Government will not pre-negotiate the departure of Scotland from the UK. Therefore, scenarios mentioned in the Scottish Affairs Committee report under which the UK may negotiate a basing agreement for the deterrent with an independent Scottish Government will not be discussed before to the outcome of the referendum and, God willing, will never need to be discussed.

As was said by the hon. Member for Airdrie and Shotts (Pamela Nash), who has just left the Chamber, NATO is a nuclear alliance, and it will remain a nuclear alliance while nuclear weapons remain in existence. NATO’s “Strategic Concept” of 2010 and the “Deterrence and Defence Posture Review” adopted at the NATO summit in Chicago only in May last year make that unambiguously clear. Those documents also make this clear:

“The supreme guarantee of the security of the Allies is provided by the strategic nuclear forces of the Alliance, particularly those of the United States; the independent strategic nuclear forces of the United Kingdom and France, which have a deterrent role of their own, contribute to the overall deterrence and security of the Allies.”

The contribution made by the UK’s nuclear forces is much valued by our NATO allies, and membership of NATO comes with responsibilities. One cannot join NATO and pretend that it is not a nuclear alliance, for it is, and one cannot join NATO and reject the concept of nuclear burden sharing within the alliance.

It is clear to me that a separate Scotland would face difficult choices about its defence arrangements. That would include decisions on the role of its armed forces, what threats it intended to counter and what foreign policy it intended to support—quite a bit of work required there, then—its international relationships, including membership of NATO; the resources allocated to defence, which we have just heard about from Mr Swinney; and the future of the defence industry in Scotland.

It is indeed the case that people in Scotland need to know how the Scottish Government propose to provide for the protection and security of Scotland if it separates, God forbid, from the UK. It is the UK Government’s view that whatever choice is made, a separate Scotland would lose significant benefits in this area that are currently delivered by Scotland being part of the United Kingdom. One of those benefits is the security provided by the armed forces of the United Kingdom, including the strategic nuclear deterrent.

Our nuclear deterrent has contributed to both our security and that of our NATO allies since the 1950s, and the continuous at-sea deterrence posture has been the central feature of our deterrence since the late 1960s. As the Trident system has been our sole nuclear weapons system since 1998, our nuclear deterrence posture is now based exclusively on CASD. Although I personally am committed and we as a Government are committed to multilateral disarmament, the circumstances that would justify the relinquishing of our submarine-based deterrent do not prevail and are unlikely to do so in the foreseeable future. For that reason, I reiterate that we have no plans to move the deterrent from Her Majesty’s Naval Base Clyde, which has a bright future not only as the base for all our submarines, but as the UK’s submarine centre of specialisation.
