Atlantic Undersea Cables: Russian Subsurface Operations

Lord West of Spithead Excerpts

Tuesday 14th April 2026 Lords Chamber

[Lord Coaker (Lab)]

The noble Baroness asks a very reasonable question, but I cannot go into some of the operational details that she requires. Suffice to say, the important thing was that the Poseidon P-8s that she identified, flying from Lossiemouth, identified the threat. We also put a Type 23 frigate out there, HMS “Somerset”. Working with other assets, they made sure that the Russian submarines were aware that we were aware of them, because of course the whole point of submarine warfare is covert activity. We found them, we saw them, we took action against them and, if we had needed to, we would have been able to deal with that as well.

[Lord West of Spithead (Lab)]

My Lords, during the Cold War, I was a member of the “red tie” group, which consisted of intelligence officers, operations teams and the defence industry. Basically, we monitored the Soviet submarine threat. By the end of the Cold War, at any given time, we knew exactly where all its submarines were. We had up to 12 of our own operational SSNs to mark them, plus American ones to mark them. If war had started, we would have killed them all within the first few minutes of that war.

I fear that we are no longer in that position. Part of the reason for that has been highlighted by my noble friend Lord Robertson, who refers to it as people’s “corrosive complacency” over a number of years. I am delighted that my noble friend the Minister has highlighted what is being done now, but I have a feeling that we have a long way to catch up. We are nowhere near that position, and we are in a state where we ought to put our military, and certainly our defence industries, on some sort of war footing to be able to catch up and to do the things that we need to do.

[Lord Coaker (Lab)]

I was just thinking about the red tie club, as I stood up. But the serious point that my noble friend makes is clearly an important one about our ability to detect and deter those who would threaten us. The importance of the activity that took place in the north Atlantic was that we were able to use the P-8s. We have nine P-8s based at Lossiemouth. Of course, not all of them are operational, although most of them are and they are enabled to detect and deter. There are other ways of detecting submarine activity, which is really important. As I say, the ability to deter and to take action where necessary is really important.

I say to my noble friend that our noble friend Lord Robertson quite rightly pointed out what he felt, and the need for the strategic defence review to be implemented and funded. That debate and discussion will move forward. I also say to him—he will be particularly interested in this, having mentioned submarines—that I was recently in Plymouth, where we are putting billions of pounds into the docks at Plymouth to ensure that we have docks which are capable of dealing and working with the submarines that we have now to increase and improve the availability of those submarines. That is true in many areas of the country. There is huge and significant investment going in. The issue for us is what we do now, in the interim, to provide the deterrent and capabilities we need to ensure that our forces are able to act in the way that they do while we wait for some of those new ships and new capabilities to become ready to us. We are looking to advance that.

I am sorry to take up noble Lords’ time but the need for this country to move to a position of war readiness is crucial. That is not a government effort but a whole of society effort. From this side of the House, from that side of the House, from all parts of the United Kingdom, to deal with the threats that we face, our population have to understand the threats that they face. We as a Government have to talk to them and all of us have to stand up and say that we will defend our country and the values that we stand for.
