Submarine Service 125th Anniversary

Ian Roome Excerpts

I thank the hon. Member for Dumfries and Galloway (John Cooper) for initiating this debate on the 125th anniversary of the submarine service.

The Liberal Democrats pay tribute to the courage and discipline of all those Royal Navy submariners who serve far beneath the waves. The UK has a proud maritime heritage, and for more than a century our subsea fleet has given our island home a critical strategic advantage. Royal Navy submarine crews operate undetected for months at a time, in cramped conditions, at a classified depth, hundreds of metres below sea level. At that depth, the water pressure is five times the fatal limit for a human being. Every person who serves in our armed forces deserves our respect, but we should acknowledge that this kind of service takes a special kind of bravery.

In the first few decades after 1901, early submarines were both experimental and dangerous. In my constituency of North Devon, a memorial in the coastal town of Ilfracombe bears the names of two local men: Leading Seaman George David Cook and Engine Room Artificer David Bennington. Sadly, both were killed in the sinking of HMS Affray in the channel in 1951. That was the last Royal Navy submarine to be lost at sea. They were just two of the brave souls who served somewhere most of us cannot imagine going.

Thankfully, modern submarines are much safer and more advanced, but looking back, we can see that the submarine service and the advent of the submarine era “torpedoed” all the accepted wisdom of naval strategy. At the time, Admiral Sir Arthur Wilson famously condemned early submarines as

“underhanded, unfair, and damned un-English”.

He is often said to have described submariners as little better than pirates, even as the Royal Navy began exploring the technology’s true potential. It is just as well that we learnt quickly.

In the past 125 years, the UK has twice seen off the terrible danger of the U-boat threat, during two world wars, while our subsea fleet has become one of the most lethal capabilities of the Royal Navy, first with conventional and now with nuclear-powered submarines, providing everything from cruise missile launch to covert naval deployment of special forces and the UK’s round-the-clock nuclear deterrent. NATO now maintains the submarine rescue system—the NSRS—which is led by the UK, France and Norway.

However, despite all the advances of the last 125 years, we know that rescuing a stranded submarine crew is difficult, and that the duty that crews volunteer for is unique. Far beneath the waves, the submarine service developed its own culture and identity—its own slang and traditions. Having served in the armed forces myself, I know just how much comes back to personnel, grit and character. Faced with isolation, stressful deployments and patrols of six months or longer at sea, it is training and teamwork that sets a submarine crew apart. That would have been just as familiar to Drake or Nelson as it is to the Royal Navy today. Last November, the Defence Committee had the chance to visit Faslane to see the work and dedication of those personnel for ourselves.

Senior figures in the Navy have expressed concerns about the difficulty of recruiting and retraining personnel for this highly specialised service several times. Changing that means making it clear that we hold the submarine service in great admiration. The silent service are a breed apart. They are usually unseen, but their duties are immense, and on this anniversary, we pay tribute to their heroism.
