Undersea Cables

Lord West of Spithead Excerpts

Thursday 8th March 2018 Lords Chamber

[Lord Ashton of Hyde]

That is a good point. It is not just transatlantic cables that are important here; the Policy Exchange report gives examples of other areas in the world where cables have broken. I am not going to say exactly what the mitigation measures are but that is what the national risk assessment is for, and the National Security Council looks at that.

[Lord West of Spithead (Lab)]

My Lords, the Minister will be aware that we first became very concerned about our cables in the 1970s; indeed, we built HMS “Challenger” at great cost to work on these cables and look at where there had been attacks and what had been done. We got rid of her when the Cold War stopped. The Russians have now started investing very heavily in nuclear submarines that can go deep and carry out attacks on these cables. At the end of the Cold War we had probably the best antisubmarine warfare and undersea warfare capability in the world, but that has slowly been eroded. What are we planning to do to look at the cables that are in deep water? The Type 26 programme is late and slow, with only a small number of ships coming, while the MPAs are still not with us. What are we doing to have ships and platforms that will enable us to go and check these lines, repair them and do the necessary work?

[Lord Ashton of Hyde]

As far as repairing them is concerned, the individual companies are responsible for that. The noble Lord asked roughly the same question in December last year, and my noble friend said that, although he could not go into details about the UK’s antisubmarine capability, any threat to the UK infrastructure is taken extremely seriously. Nowadays it is not just submarines, of course; any so-called civilian vessel that can have drones on board can do the same. The main defence is resilience and lots of different cables, because there are just over half a million miles of cable to monitor in the world.
