North Atlantic Submarine Activity

Matt Western Excerpts

I am glad that the Government took a defensive stance on Iran. We were clear that we did not have a legal mandate, there was not a plan and there was no clear end state, and if we are going to put people in harm’s way, we need those three things before we can do so.

While the defence investment plan not has not arrived yet, five classes of ship or submarine are on order or being built, including 13 frigates on order—eight Type 26s and five Type 31s—which is a collaborative effort to ensure that our maritime capability is fit for purpose as threats diversify and increase, in particular in the High North. We are learning the lessons from Ukraine and ensuring that we have the best autonomous capability, and our Atlantic Bastion platform is moving in the right direction. We have worked exceptionally hard, and the Foreign Office is pushing as well, to sanction thousands of Russian individuals, companies and, of course, vessels, to reduce the illegal flow of resource back into Russia, which is funding the illegal and brutal war waged by Putin on Ukraine.

I thank my hon. and gallant Friend for his statement. GUGI has been at work since the 1960s, as I understand it; it has been doing extensive mapping for quite some time. In our report on subsea cables, the Joint Committee on the National Security Strategy came up with a great many recommendations, with which he will be more than familiar. When it comes to the defence investment plan, may I draw his focus to our recommendation on a sovereign capability in repair ships? Will he promise to look at that or agree to meet me to discuss it?

[Al Carns]

I thank my hon. Friend for his really focused question. We have been watching the underwater research programme for years now. We understand exactly what they are up to and why they are up to it. They understand some of the vulnerabilities—I would not say weaknesses—in the west, and they are trying to identify and, indeed, threaten them at a point in time of their choosing. I recognise the report’s recommendation on a sovereign capability to fix cables. We are working with industry and partners, and of course we have a multitude of capabilities within defence that can support the types of operations that may need to take place should anything happen to our undersea cables.
