I knew I would get it wrong. My hon. Friend also mentioned the efforts of her constituents in contributing to this national endeavour.

The backlog of 23 decommissioned submarines that have yet to be dismantled and recycled, which has built up over many years—seven are stored in Rosyth and 16 in Devonport—is a longstanding and ongoing issue that needs to be resolved. The previous Government set out on a path to resolve it, and we intend to continue and make sure that that work is done.

While hon. Members should be in no doubt that our submarine capabilities are the envy of the vast majority of countries in the world, the disposal backlog is one of the challenges across the portfolio of the Submarine Delivery Agency that it identified in its most recent annual report, resulting from historic underinvestment in capability and infrastructure over many years. As a Government, we are committed to defueling, dismantling and disposal of those submarines, and to meeting our responsibilities at every stage of the life-cycle of our fleet. Defueling and disposal are complex tasks, and Ministers, our Submarine Delivery Agency, and our entire defence nuclear enterprise take their responsibilities extremely seriously.

HMS Swiftsure was mentioned by my hon. Friend the Member for Dunfermline and Dollar, and workers at Rosyth yard, as he knows very well, are in the process of entirely dismantling it, which is on track to be completed by the end of 2026. That will make HMS Swiftsure the first decommissioned Royal Navy nuclear submarine to be fully dismantled, with around 90% of its structure and components being reused or recycled. This is a demonstrator programme, designed to identify methods of dealing with the backlog of decommissioned submarines swiftly and safely—and, I might say, “surely”, given the name of the submarine, but that is a very corny joke. We intend to do that in a way that provides the best value for money for the taxpayer.

The responsible and innovative approach we are taking has a strong focus on sustainability. By extracting the reactor rather than storing the whole reactor compartment, we are recycling a greater proportion of each submarine and dramatically reducing the volume of radioactive material being placed in long-term storage. We are also ensuring that steel from decommissioned hulls will be able to be reused to support the manufacture of future UK-built submarines.

Workers at the Rosyth yard have also successfully and safely completed the initial stage of the dismantling process on four decommissioned submarines—which should give my hon. Friend the Member for Dunfermline and Dollar some reassurance about future work that is going on. That will pave the way to accelerate the programme, having learned, from HMS Swiftsure, the best way of going about it, and should sustain high-skilled jobs in Rosyth as we deal with this legacy.

In parallel, we are evaluating our long-term options for future submarine disposal capability in the UK, using the lessons being learned from HMS Swiftsure, to enable us to dispose of future classes of submarine as they leave service, rather than having to park them at Devonport again and then wonder what to do with them thereafter. The submarine disposal capability project was established in 2022, as I am sure the hon. Member for South Suffolk and you, Dr Murrison, recall, to identify an enduring disposal capability for future submarines. The project is still in its concept phase, assessing all options for a future submarine disposal capability within the UK. An initial study has shown that there were various potential sites for disposal, including Rosyth. That work was investigative.

[Jim Shannon]

I thank the Minister for her very comprehensive response. I am very keen to see that we all realise the potential from the dismantling of the submarines, and I know the Minister is very keen on that, too. Is there any possibility that we in Northern Ireland could be part of that, perhaps through Harland & Wolff and others?

[Maria Eagle]

I am going to have to go back to my officials and interrogate them about what the possibilities are in Belfast. It is not a place where submarine work or nuclear work has previously been done. There will be criteria that any potential place would have to meet in order to do that, but I will certainly go back and challenge my officials about the extent to which Belfast—

[James Cartlidge]

The Minister makes an important point, because, as she knows, there is essentially a blockage in the infrastructure caused by having all these submarines awaiting dismantling. Will she confirm that she will be looking all over the country for potential places to add capacity? I am sure she agrees it could be immensely valuable economically to those areas that get involved.

[Maria Eagle]

I can, of course, confirm that. We are more than willing to look at any suggestions that any hon. Member might have.

I would like now to try to answer some of the specific questions raised by my hon. Friend the Member for Dunfermline and Dollar—it is his debate. He asked specifically about the well-being of submariners, and about what is being done and what more can be done to support them and their families. We are aware of the pressure put on submariners and their families during their long periods of absence. They are given extensive training prior to deployment to try and help to them prepare for life underwater and for life away from their families for such a long time. They have access while at sea to a weekly short message from their nominated loved one, which should help, although it is, of course, not quite like being in the same place at the same time.

When returning from deployment, submariners have access to the Royal Navy family and people support services, which can offer a range of specialist, tailored welfare services if they are needed. Recognising the impact on families, the Royal Navy has also worked to enhance support for families of those deployed, backed by service charities, so there is work there. We are conscious of the extra pressure that exists, and we take steps to try to make sure that there is support and help.

My hon. Friend also asked what assessment I can make of the Astute fleet, and whether it is able to carry out its intended role. The fleet is perfectly capable of carrying out all of the roles that are required of it. As my hon. Friend knows, there are two more Astutes that are not currently commissioned yet—HMS Agamemnon and Astute Boat 7. We will continue to build those, and we expect that the new class to replace Vanguard will also be fully built—certainly, the first boat is currently on target in terms of timing—so we are confident that the fleet can do what it is intended to do.

My hon. Friend also asked what steps have been taken in regards to the NAO findings to ensure that the defence nuclear enterprise is delivering effectively and efficiently. The organisations that make up the defence nuclear enterprise are working more closely than ever before, operating effectively as an integrated team to ensure the maintenance of the continuous at-sea deterrent posture. We are harnessing expertise and experience of multidisciplinary teams to deliver this mission and are committed to sustainment and renewal of the nuclear capabilities for as long as is required. The NAO’s work is tremendously valuable to us. It shines a very positive light and focuses minds in the Department and the defence nuclear enterprise on making sure that we do the best we can to get value for money and deliver on time and to budget.

My hon. Friend the Member for Dunfermline and Dollar asked me about the budgets. He discerned from a parliamentary question the £9 million per year cost of maintaining submarines that are awaiting disposal, and he asks whether that reduces the £298 million budget for the major project portfolio data, which he got from a parliamentary answer. Obviously we do not release particular spending profiles for individual programmes, but I can tell him that the latest whole-life cost for the submarine dismantling project is £298 million, and that figure includes costs associated with dismantling work in Rosyth and maintenance costs for decommissioned submarines in Devonport.

My hon. Friend asks if I will work with Babcock, Fife council, Fife College and other local partners to help to turn Rosyth into a world-leading centre for submarine dismantling. He wants a quick announcement on the next stage of the programme. We are currently learning lessons from the dismantling of Swiftsure, which he already knows is on target to be completed by the end of next year. It will pave the way for future dismantling—my hon. Friend knows that there are already four submarines there and that the first stages of the process have already been undertaken for them. Once that work is done and we have finished with Swiftsure, we will look to accelerate the programme in Rosyth, drawing on the lessons we will have learned. That will sustain high-skilled jobs and support sustainability. My hon. Friend will see that we will have made more progress by then on the future of submarine disposal capability.

I am happy to work with my hon. Friend and his local council and other organisations—indeed, we already do. There is a partnership between the MOD, the Royal Navy, and local authorities and nearby universities and colleges called the Arrol Gibb Innovation Campus. Three projects that relate to Rosyth are currently earmarked there for funding. We are more than happy to try to assist in making sure that the local area and his constituents get best value for the money being spent in Rosyth. I hope that answers some of my hon. Friend’s questions.
