North Atlantic Submarine Activity

Charlie Dewhirst Excerpts

Monday 13th April 2026 Commons Chamber

[Al Carns]

We regularly make clear to our Russian counterparts what they are up to and what is happening, and ensure that the severity of their activities is explained to them. The idea that Russia poses no threat to our critical national infrastructure is fundamentally wrong. The reason for Russia’s mapping it and trying to understand it is to find a gap, develop capabilities and, at a time of its choosing, perhaps use them. We acknowledge that we are watching. We have clear indicators and warnings, and I have complete assurance in our armed forces’ ability to deter it.

[Charlie Dewhirst (Bridlington and The Wolds) (Con)]

The Minister may be aware that the RAF’s investment in the P-8 submarine hunting programme was made in 2015, at a time when Russian activity in the north Atlantic was much less of a threat to the UK. I welcome the £100 million announced just now, but that is less than one third of the cost of one of those aircraft, so can I ask him what assessment he has made of the P-8 submarine hunting capability in the light of the increased Russian activity? Will he assure the House that he will go further if the RAF needs him to?

[Al Carns]

That is a fantastic question. The Nimrod capability was taken out of service many years ago. The P-8 programme is a huge success. Many other allies and partners use those same aircraft. When we combine that with some of the best frigates and the best Navy personnel, and with our subsurface capability, that multi-domain spectrum of finding submarines and tracking them is second to none. A £100 million investment has gone into the P-8 programme. Of course we will ensure that that money is spent wisely on maintenance, and other gaps if required, and we will spend more if there are issues with the P-8 programme in the future. It is the frontline of our deterrence and indicator network.
