Admiral Sir Tony Radakin, Chief of the British Defence Staff has told The Times that Russia is a major threat to the UK and its allies at sea. Russian submarines are very active and they could cut undersea cables in a war, which would severely damage the economies of the affected countries by severing their overseas communication links.
Radakin has, however, had a recent telephone call with General Valery Gerasimov, his Russian counterpart., the first such call since 2019.
In 1914, Britain cut Germany’s trans Atlantic cables, but cable communications were not then as vital to commerce as they now are.
Radakin also warns of the threat from Russia’s 3,850 mph hypersonic missiles. It test fired 10 from a frigate and two from a submarine last month. China has also tested such missiles and North Korea claims to have done so.
