He told The Times: “There’s been a phenomenal increase in Russian submarine and underwater activity over the last 20 years.”

He said Russia has grown the ability to put the undersea cables where the world’s information and traffic travels under threat.

When asked by The Times if destroying the cables “would be considered an act of war”, Radakin answered: “Potentially, yes.”

One asset currently held by Russia is hypersonic missiles which can fly at five times the speed of sound and at lower altitudes than ballistic missiles.

To compete against Russia’s military strength, Radakin said there’s work to be done.

He said: “We haven’t [got them] and we must have.”


His comments come after a Russian submarine crashed into a Royal Navy warship in an unbelievable clash.

A crew member can be heard shouting “what the f**k have I just hit?” after the HMS Northumberland struck the “hunter-killer” sub in the icy north Atlantic.

The dramatic collision – which is believed to have been an accident – was caught on film by a Channel 5 TV crew whilst shooting for the show Warship: Life At Sea, which airs on Mondays at 9pm.

It is thought to be the first collision between Russian and Royal Navy vessels since the Cold War.

It was feared that the Russians would try to cut undersea cables that are essential for internet and communication in the UK.

A Russian spy ship that is believed to be able to cut undersea cables was spotted in the English Channel in September, 2021.

Vladimir Putin’s Yantar was caught loitering between the coast of Devon and France and appears to be heading north.

The internet cables and other crucial undersea infrastructure are vital to sharing information between countries.

Just severing cables has the capacity to bring Britain to a complete standstill, as a 2006 earthquake in the Luzon Strait between Taiwan and the Philippines showed.

There, six out of seven cables used to distribute internet and phone services from North America to Taiwan, China, Hong Kong, Japan, Singapore and South Korea were severed.

That led a 100 per cent internet outage to Hong Kong and South East Asia, cutting off millions of citizens and businesses from internet and mobile phones.

It has been estimated that cutting three cables could lead to some countries losing 70 per cent of their data traffic.
