Undersea Cables: National Security Threat

Lord Stirrup Excerpts

Monday 27th October 2025 Lords Chamber

[Lord Coaker (Lab)]

We certainly should develop one, and we are developing one. My noble friend is right to highlight that. We are undertaking a number of actions including surveillance aircraft from Lossiemouth, the ship “Proteus” looking at how it protects underwater assets, and the Royal Navy ship “Stirling Castle” looking at how it might operate drones from its deck to secure underwater pipelines, data cables and so on. We are doing a lot, but my noble friend is right to point out the importance of this.

[Lord Stirrup (CB)]

My Lords, Ireland is a crucial hub for undersea infrastructure crossing the Atlantic, but it lacks the capabilities to defend against and be resilient to the destruction of that infrastructure. Moreover, its individual tailored partnership programme with NATO is coming increasingly under threat with recent political shifts in Irish leadership. What assessment have the Government made of the UK’s vulnerabilities to Ireland’s position, and what plans do they have for developing a resilience strategy in that regard in future?
