UK Submarine Fleet

Torcuil Crichton Excerpts

Wednesday 15th January 2025 Westminster Hall

[Graeme Downie (Dunfermline and Dollar) (Lab)]

I beg to move,

That this House has considered the UK submarine fleet.

It is a pleasure to serve under your chairmanship, Dr Murrison. The UK submarine fleet has a long and distinguished record, always at the heart of this nation’s deterrence and defence policy. It began in 1900 when the Royal Navy ordered its first five submarines—the Holland class. In 1901, six officers were recruited for the submarine service under the leadership of Reginald Bacon, the inspecting captain of submarines.

Since the early days of the submarine service, Scotland has been at its heart. In 1909, Dundee became home to the 7th Submarine Flotilla. By 1914, the submarine service consisted of 168 officers, 1,250 ratings and 62 submarines, and the fleet was moved to Rosyth in my constituency. Without offending any hon. Members from the great city of Dundee, Rosyth was obviously a much better choice, and it retains a strong role in the submarine story to this day.

The role of the submarine service in world war one should never be forgotten, with five of the 14 Victoria Crosses awarded to the Royal Navy during the conflict being awarded to submariners. Although the focus of naval warfare in world war two is often thought to be the battle of Atlantic, I was fascinated to learn from the excellent podcast “We Have Ways of Making You Talk” with Al Murray and James Holland of the vital role of British submarines in the Mediterranean. For example, HMS Upholder sank around 119,000 tons of enemy shipping. It was commanded for its entire life by Lieutenant Commander Malcolm Wanklyn, one of the most successful submarine commanders of the conflict, who received the Victoria Cross for attacking a well-defended convoy in May 1941.

The cold war saw the submarine fleet play a key part in deterrence and intelligence-gathering capability. HMS Swiftsure, a ship I will come back to later, became famous for her mission to acquire the acoustic signature of the Soviet aircraft carrier Kiev, with her periscope raised just 10 feet underneath the carrier’s hull. In the Falklands, HMS Conqueror became the first and, to this day, only British nuclear-powered submarine to engage an enemy ship with torpedoes. After the attacks on the US on 11 September, HMS Trafalgar and HMS Triumph played a vital role in hitting al-Qaeda targets in Afghanistan. Throughout, submarines have had extensive capability and roles assisting UK special forces in their vital missions.

Today, the Royal Navy operates a fleet of nine submarines, with a little over 1,100 submariners. Four are ballistic missile submarines of the Vanguard class that comprise the UK’s submarine-based independent nuclear deterrent, along with five nuclear-powered Astute class with the capability of launching Tomahawk cruise missiles at land-based targets and Spearfish torpedoes at maritime targets. The submarine fleet is spread across the UK. Faslane in Scotland is now the home base for the fleet; Devonport undertakes major refit, maintenance and decommissioning; and Barrow-in-Furness is the manufacturing location of both Astute and the next Dreadnought class of submarines.

At Rosyth, Babcock is undertaking work on the submarine dismantling programme—more on that later, as well—and is also a manufacturer of missile tubes for the Royal Navy and the US navy. QinetiQ, also in my constituency, houses world-class scientists, engineers and technicians, who support our men and women on the frontline by ensuring that Royal Navy ships and submarines remain at the cutting age of technology.

As I have outlined, the role of submarines in history has been varied. Indeed, the flexibility of the fleet is one of its strengths. The role of submarines is necessarily secret, but it is clear that the need for subsurface protection is both critical and increasing. In 2022, the Chief of the Defence Staff, Admiral Sir Tony Radakin, said:

“There’s been a phenomenal increase in Russian submarine and underwater activity over the last 20 years.”

[Torcuil Crichton (Na h-Eileanan an Iar) (Lab)]

I commend my hon. Friend for raising this issue. He talks about the increase in Russian and foreign-state activity in the waters. The role of the Royal Navy and submarine fleet in protecting us from that is vast. I welcome the announcement by the Secretary of State for Defence last week that the joint expeditionary force will now monitor Russia’s shadow fleet in the Baltic. I hope that work extends to the north Atlantic, where there is a massive gap. Our frontline lies in our backyard, just beyond my constituency and my hon. Friend’s.

[Graeme Downie]

My hon. Friend is absolutely right. In doing research for this debate, I was fascinated to learn about the maritime range that exists off the west coast of Scotland, which is very close to his constituency. He is absolutely right that we need to ensure that our forces are defending our entire coastline, and places such as his constituency are vital to that, as are the whole of the west and north coasts of Scotland.

More recently, we have been aware of the ongoing undersea threat from Russia, most recently in the sabotaging of undersea cables in the Baltic sea. Submarines will clearly play a vital role in combating those efforts by our opponents. That is not to mention the critical role of the UK’s independent nuclear deterrent and maintaining the capability of the submarine force to support both maritime forces and those on land.

With that in mind, I turn to some of the issues faced by our submarine fleet and submariners, and the actions needed to ensure that they remain at the forefront of our armed forces now and in the future, while continuing to make a vital contribution to our economy and skills development.

I have relatives who have served in the Royal Navy, and I know from speaking to them how difficult the life of a submariner can be. Like other parts of the armed forces, the Royal Navy and the submarine service have struggled with both recruitment and retention. The basic salary for a submariner is £25,000, although it can rise to more than £37,000 with bonuses. None the less, the First Sea Lord has warned:

“We are effectively in a war for talent in this country”.

He also said that

“the submarine service…go through significant periods of real social isolation from the people they love…we must ensure the pressures that are inevitably felt by them are mitigated or eased or supported as best we can.”

Will the Minister say what is being done to support submariners and their families, and what more can be done, to ensure that we have an adequate force for the future?

I turn to future capabilities and the question of whether the submarine service has the right equipment to carry out its role. In its excellent January 2024 report “Ready for War”, the Defence Committee included evidence from Dr Rowan Allport of the Human Security Centre, who expressed this concern:

“Even once all seven Astutes are in service, it is questionable whether the force will be able to sustain their current tasks and the additional deployments to Australia and wider region from 2026 onwards.”

What assessment has the Minister made of that? Does she believe that the Astute fleet is able to carry out the role we intend it to have?

The independent deterrent is a vital service for the security of our country, and we must ensure that it is effective now and in the future. The last Conservative Government left a total deficit of £16.9 billion in the equipment plan for 2023 to 2033, of which the defence nuclear enterprise makes up nearly half, at £7.9 billion. In its report on the Ministry of Defence for the new Parliament, published in October last year, the National Audit Office found key risks in the defence nuclear enterprise relating to costs, skills, commercial relationships and delivery to schedule, and it said that those need to be

“carefully managed as DNE activity and spending increase.”

What steps is the Minister taking in the light of the NAO’s findings to ensure that the DNE is delivering effectively and efficiently?

Finally, as the Minister might have predicted—I have raised this in the House many times—I will talk about what progress the MOD is making on submarines that have been retired from service. Since 2023, the Babcock team at Rosyth in my constituency has been undertaking a demonstrator project to dismantle HMS Swiftsure—the ship I mentioned earlier that played such a vital role in the cold war—in a safe and secure way that protects the environment. That will lead to 90% of HMS Swiftsure being reused or recycled and the remainder being safely disposed of. That kind of work is not being done anywhere else in the world, and it currently employs more than 200 people in my constituency.

There are a total of 23 retired submarines—including HMS Swiftsure—currently being stored between Rosyth and Devonport that could be dismantled in a similar way. Given the knowledge and experience needed, along with the highly skilled nature of the roles, there is an opportunity to use the demonstrator project to establish Rosyth as a centre of excellence for submarine dismantling. From answers to written questions, we know two things regarding those 23 submarines: it costs £8.8 million a year to maintain the submarines at Rosyth and Devonport in their current condition, and the whole-life cost of the submarine dismantling project is £298 million.

I have two specific questions for the Minister about those figures. Can she assure me that the cost of almost £9 million a year to maintain those submarines where they are is not slowly reducing the £298 million budget? Will she work with me, Babcock, Fife council, Fife college and other local partners to help to turn Rosyth into the worldwide centre of excellence for submarine dismantling? When will she be in a position to announce the next stages of the submarine dismantling project? That announcement could be vital for the ongoing success of the defence industry in my constituency and its ability to drive local economic growth and provide secure, well-paying jobs for local people.

In closing, I put on record my thanks to the members of the submarine service, the Royal Navy and all our armed forces for the work they do every day to keep us safe. We are living in an increasingly volatile and unstable world and, sadly, it feels like our armed forces will be required to play an increased role in deterring our opponents and supporting our allies around the world in coming years. This House must be united in supporting our armed forces now and in the years to come.
