Aukus: US, UK and Australia to develop underwater drone technology

In December, the UK and Norway signed a pact to hunt Russian submarines in the North Atlantic to protect undersea cables.

The UK is connected by about 60 undersea cables, which British officials say are increasingly under threat from Moscow, with a 30% rise in Russian vessels spotted in UK waters over the past few years.

Elsewhere, Chinese ships are suspected to have damaged undersea cables in waters surrounding Taiwan and in Swedish territory.

There have also been multiple reports of cables damaged in the Baltic Sea.
