British, Norwegian and American forces confronted vessels linked to Russias deep-sea research directorate during exercises conducted in Arctic waters
this spring. The reported operation did not damage any cable, but officials said the equipment could remove evidence that would identify its use after an attack.

Officials said the device could cut communications lines while leaving little physical evidence capable of connecting Moscow to the incident. You may like Chinese ship spotted 'lurking' near Taiwan's subsea internet cables linking

The confrontation occurred near Svalbard, where two fiber-optic cables extend for about 1,400km and descend roughly 2,700 meters underwater.

Those lines support data transfers from SvalSat, a major satellite ground facility that also serves NASAs Near Space Network in orbit. Are you a pro? Subscribe to our newsletter Sign up to the TechRadar Pro newsletter to get

The cables are only around garden-hose thickness, yet they support services carrying enormous quantities of information between the Arctic territory and Norway.

Norway is developing another connection involving Svalbard and Jan Mayen,
with completion expected during 2028 under its current infrastructure plans.

The location matters militarily because vessels from Russias northern naval facilities must cross the Bear Gap when entering Atlantic waters. What to

That passage spans roughly 400 miles, making nearby infrastructure
significant for communications and surveillance across the wider High North region. Why NATO is concerned about the cable-cutting capability Western intelligence officials have become increasingly concerned that Moscow could expand covert disruption against critical infrastructure across Europes vulnerable networks.

Three American officials told Reuters that subsea communications lines could feature in a future attempt to test NATOs collective-defense commitment.

CIA Director John Ratcliffe travelled to Moscow in August for discussions
that included warnings about escalating sabotage activity in Europe.

Russia has rejected accusations that it conducts sabotage inside NATO countries or seeks direct military confrontation with the alliance, but
Norway is not having it.

"Through our joint operation, we sent a clear message to Russia that they cannot operate covertly," Norway's Defense Minister Tore Sandvik declared in
a statement.

"We have made it unequivocally clear to Russian authorities that any attempt to target our critical infrastructure will be detected and met with consequences."

Earlier British disclosures also linked Russian deep-sea submarines with activity near British waters involving energy pipelines and
telecommunications systems.

Britain subsequently allocated another $136 million toward P-8 maritime
patrol aircraft as suspicious Russian vessel movements increased around vulnerable infrastructure.

Undersea cables carry about 99% of Britains international telecommunications and data traffic, raising concerns about disruptions to essential public services.

British and Norwegian officials have carried their findings to Moscow, apparently hoping public disclosure would discourage any future use of the technology.

However, reports so far do not establish that Russia has used this device against a cable, but rather that it has rehearsed its deployment.
