Britain has previously reported Russia poses a threat to underwater internet cables.
In an interview, NATO Secretary General Jens Stoltenberg has warned of Russia expanding it's naval operation saying;
"Russia's submarine activity is now at its highest level since the Cold War."
Britain has been working in partnership with NATO aircraft to monitor any threat in the North Atlantic.
