Defence: Continuous At-Sea Deterrent — House of Lords, 2016-07-13
Topic: Defense
Alan William John West (Labour, Centre-left): My Lords, for almost four years, from 2002 to 2006, I was responsible directly to the Prime Minister for the safety, security and operational capability of the deterrent, so I know it intimately. As the noble Earl said, since 1968 the Royal Navy has maintained at least one ballistic missile submarine continuously undetected on patrol at sea 24 hours a day, every day of every year. It is a remarkable achievement that deserves the nation’s praise We are discussing today the replacement of our four Vanguard-class submarines to enable the Trident missile system to continue to provide continuous at-sea deterrence for the next few decades. The first decision is whether we wish to remain a nuclear weapon state or to opt for unilateral nuclear disarmament. If we decide we should maintain a deterrent, what is the most cost-effective weapons system We are in a highly dangerous and chaotic world that is becoming even more unstable. Indeed, it is the most unstable I have known in my 50 years on the active list of the Royal Navy. Our record as human beings in circumstances of intense competition has not been good, and I believe that keeping our armour bright, particularly those elements which provide assurance of our ultimate survival, is crucial. Many doubters seem unwilling to acknowledge the unforeseen shocks caused by imbalance of population and resources and the actions of opportunistic, possibly desperate, regimes. We seem pretty bad at predicting what will happen tomorrow. Indeed, who could have predicted 30 minutes ago that Boris would be our Foreign Secretary? So no one can predict whether in the next 50 years there may be nations prepared to use nuclear weapons. What is certain is that their use is unlikely if that use means self-destruction. It would be foolhardy for any British Government of whatever hue to make us vulnerable to nuclear blackmail by giving up the power to retaliate Unilateralists often ask why, in that case, countries such as Germany, Canada, Australia and Japan do not need the deterrent. That fact has no bearing on our decision. The reasons are historical, such as the cost of starting from scratch, alliances, and satisfaction with others’ nuclear umbrella. Suffice it to say that all permanent members of the Security Council possess nuclear weapons, as do an ever-expanding number of other countries. Opponents also state that it will not stop terrorists. Of course it will not. It is not meant to and no such claim has ever been made for it As a number of noble Lords have said, we have led the world in reducing the number of nuclear weapons systems—we have only one, unlike any of the other permanent members of the Security Council—and the number of warheads. Has that reduction had any discernible impact, particularly on those states we would hope to discourage from owning nuclear weapons or expanding their number? No, it has not. We would certainly not be part of any negotiations on multilateral arms reductions—which all of us want—should we cease being a nuclear weapon state I have no doubt that we should remain a nuclear power. Unilateral disarmament would endanger our nation and our people and it is not what most UK citizens want. But what system should we use? Study after study has shown conclusively that the cheapest, most cost-effective option is to maintain the present Trident ballistic missile system. This necessitates the replacement of the Vanguard-class submarines. As the noble Baroness, Lady Falkner, said, the last study was the Trident alternative review, which was instigated by the Lib Dems. Much to the surprise of many of those who instigated it, it concluded that we should replace the Trident submarines. Every study has always said that. Having looked at other options in detail, it is quite clear—and I have been involved with three previous such studies—that none of them is as cheap or practical as their supporters claim, certainly not cruise missiles; I could give you a 100 reasons why not to go down that route Let us face it, none of our nuclear submarines has ever been counter-detected. They are so quiet and undetectable, one of them bumped into a French one without knowing it, and the French one did not know what it had bumped into. The very invulnerability of the submarine to detection now and in the future, notwithstanding claims to the contrary by unqualified people with no knowledge of the oceans or anti-submarine warfare, and the assuredness of warhead delivery, make it the ultimate post-strike system. We need a post-strike system. I could go into that for hours but I will not There has been considerable debate about the need for a submarine to be permanently deployed—this is what CASD is: continuous at-sea deterrence—and hence the need for four submarines. There is no doubt that such a deployment makes the force invulnerable to pre-emptive strike. We live in a world where the enemy has an option and people do nasty things—we forget that. It also avoids the risk of escalating a crisis by sailing a submarine in times of tension, which makes that submarine more vulnerable. When one adds the efficiency and readiness of the crew by being deployed, it is hardly surprising that study after study has shown the need for continuous at-sea deterrence Another concern expressed by detractors is that the system is not truly independent. In 2009, as Security Minister, I was asked by the Prime Minister to conduct a detailed and comprehensive investigation. I can assure the House and the nation that it is totally independent of the US. Although cheaper than most alternative options, the replacement of four Vanguard-class submarines is expensive. All defence systems are expensive. The cost has already been mentioned: 0.13% of GDP for our ultimate insurance policy. This seems pretty reasonable when one thinks of what one pays for one’s car and house as a percentage of one’s income. The cries from a few military figures that dropping the deterrent will release funds for conventional forces is totally delusional. I have spent many years in Whitehall and clearly those involved do not understand the Whitehall jungle I have little doubt that those who are attacking the Trident capability—in the context of cyberattack and drones—are actually closet unilateralists. They ought to be honest about this, because there is no doubt that Trident is the best system to go for if we wish to remain in the game. If they want to be unilateralists, that is perfectly respectable but they should say that and not try to do it through the back door An additional point—not a driving factor but I think it is quite important for the nation—is that the replacement of the submarines will ensure that 12,000-plus engineers, scientists and designers are directly employed for the next 25 years, plus a number of ancillary occupations. What does worry me is the seeming delay in setting up the new delivery authority that the Government have referred to. When will it be stood up? Have the US Government been consulted? Will it require primary legislation? Have the Government identified the man who should be responsible directly to the Prime Minister for delivering this complex programme, which is so crucial to the security of our nation? We need one man who is responsible for it to the Prime Minister to make things happen, because you can chop off his head if he gets it wrong. These things are a matter of urgency. Our Vanguard-class submarines are already going to be extremely old when replaced The case for maintaining our minimum credible deterrent by replacing the ageing Vanguard-class submarines with Successor is compelling, and there is no doubt that if we wish to remain a nuclear power, the replacement of the V-class is the only sensible option. For the safety and security of our people and our nation, we should remain a nuclear power. It is unsurprising that that is the Labour Party’s manifesto commitment and Labour policy—and that is what it is.
