Continuous At-Sea Deterrent

Neil Gray Excerpts

Wednesday 10th April 2019 Commons Chamber

[Gavin Williamson]

My hon. Friend makes an important point, which I will touch on later. Our nuclear deterrent is a cornerstone of that long and enduring relationship. The United States does not have such a relationship with another country anywhere on this Earth. That close collaboration makes us and our allies safer.

[Neil Gray (Airdrie and Shotts) (SNP)]

Will the Secretary of State give way?

[Gavin Williamson]

I will make some progress. I am sure the hon. Gentleman will appreciate that.

The extent to which our deterrent underpins our special relationship with the United States must never be underplayed. We should be proud of the fact we are one of the few nations with both strategic nuclear and conventional carrier capabilities. We should be proud that those strengths give the United Kingdom influence not just in NATO but across the world, giving us the capability to influence events in our interest and stand up for our values and the United Kingdom.

My third point is that there are simply no credible alternatives to the submarine-based deterrent. Some claim that there are cheaper and more effective ways of providing a similar effect to the Trident system, but we have been down that road many times before. Successive studies by both Labour and Conservative Administrations have shown that there are no other alternatives. Most recently, the Trident alternatives review of 2013 found that submarines are less vulnerable to attack than silos or aircraft and can maintain a continuous posture in a way that aircraft and land-based alternatives cannot. Their missiles have greater range and capability than other alternative delivery systems. Overall, the review concluded that a minimum, credible, assured and independent deterrent requires nuclear submarines with ballistic missiles.

[Gavin Williamson]

We could spend a long time debating the Liberal Democrats, but it would probably be a waste of time. I am exceptionally proud of the fact that this Government have committed to a nuclear deterrent, and that in 2015 so many colleagues from both sides of the House united in one Lobby to make sure we delivered it.

[Gavin Williamson]

I see that a very excitable member of the SNP is keen to make a point.

[Neil Gray]

We were not in that Lobby, funnily enough. I struggle to see the logic in arguing for multilateral disarmament while simultaneously rearming unilaterally. My question to the Secretary of State is this: how many nuclear submarines have been successfully decommissioned since 1980? The answer is none, isn’t it?

[Gavin Williamson]

We are intending to see the first decommissioning of submarines over the coming year. That important issue needs to be addressed. My hon. Friend the Member for Berwick-upon-Tweed (Anne-Marie Trevelyan) and the hon. Member for Plymouth, Sutton and Devonport (Luke Pollard) have been looking at it and have made some very important contributions. It is an issue that the Ministry of Defence takes very seriously. I was hoping—this was obviously very naive of me—that the hon. Member for Airdrie and Shotts (Neil Gray) was going to talk about Scotland’s pride at being the home of our submarine forces, about the economic benefit that our continuous at-sea nuclear benefit delivers Scotland, about the fact that 6,800 people are employed at Her Majesty’s Naval Base Clyde and about the fact that that will increase to 8,500. It is disappointing that he could not talk with a bit of pride about the service personnel who contribute so much. This is about saying thank you, to the submariners who have continuously put their lives at risk and done so much for our nation to keep us safe. I hope that all Members in this House, regardless of their view about the continuous at-sea nuclear deterrent, will have the courtesy to pay tribute to those brave men and women. We cannot wish away the rise of the atomic bomb, especially given that there are some 14,500 nuclear weapons on this Earth. That is not to say we have given up our determination to create a nuclear-free world. On the contrary, we have been at the forefront of arms reduction. Since the height of the cold war, the United Kingdom has reduced our forces by more than 50%. We have delivered on our commitment to reduce the number of warheads carried by our Vanguard submarines from 48 to 40, and we have decreased the number of operationally available warheads to no more than 120.
