UK's Nuclear Deterrent

Nicholas Dakin Excerpts

Monday 18th July 2016 Commons Chamber

[The Prime Minister]

My hon. Friend is absolutely right. This is about jobs here in the United Kingdom, and it is also about the development of skills here in the United Kingdom that will be of benefit to our engineering and design base for many years to come.

The decision will also specifically increase the number of jobs in Scotland. HM Naval Base Clyde is already one of the largest employment sites in Scotland, sustaining around 6,800 military and civilian jobs, as well as having a wider impact on the local economy. As the base becomes home to all Royal Navy submarines, the number of people employed there is set to increase to 8,200 by 2022. If hon. Members vote against today’s motion, they will be voting against those jobs. That is why the Unite union has said that defending and securing the jobs of the tens of thousands of defence workers involved in the Successor submarine programme is its priority.

On the issue of jobs, there is a lot of steel in Successor submarines, so will the Prime Minister commit to using UK steel for these developments?

[The Prime Minister]

The hon. Gentleman might have noticed that the Government have looked at the Government procurement arrangements in relation to steel. Obviously, where British steel is good value, we would want it to be used. For the hon. Gentleman’s confirmation, I have been in Wales this morning and one of the issues I discussed with the First Minister of Wales was the future of Tata and the work that the Government have done with the Welsh Government on that.

I will now turn to the specific question of whether building four submarines is the right approach, or whether there are cheaper and more effective ways of providing a similar effect to the Trident system. I think the facts are very clear. A review of alternatives to Trident, undertaken in 2013, found that no alternative system is as capable, resilient or cost-effective as a Trident-based deterrent. Submarines are less vulnerable to attack than aircraft, ships or silos, and they can maintain a continuous, round-the-clock cover in a way that aircraft cannot, while alternative delivery systems such as cruise missiles do not have the same reach or capability. Furthermore, we do not believe that submarines will be rendered obsolete by unmanned underwater vehicles or cyber-techniques, as some have suggested. Indeed, Admiral Lord Boyce, the former First Sea Lord and submarine commander, has said that we are more likely to put a man on Mars within six months than make the seas transparent within 30 years. With submarines operating in isolation when deployed, it is hard to think of a system less susceptible to cyber-attack. Other nations think the same. That is why America, Russia, China and France all continue to spend tens of billions on their own submarine-based weapons.

Delivering Britain’s continuous at-sea deterrence means that we need all four submarines to ensure that one is always on patrol, taking account of the cycle of deployment, training, and routine and unplanned maintenance. Three submarines cannot provide resilience against unplanned refits or breaks in serviceability, and neither can they deliver the cost savings that some suggest they would, since large fixed costs for infrastructure, training and maintenance are not reduced by any attempt to cut from four submarines to three. It is therefore right to replace our current four Vanguard submarines with four Successors. I will not seek false economies with the security of the nation, and I am not prepared to settle for something that does not do the job.
