Within the bitterly chilly seas across the Shetland Islands, the sight of trawlers plying their commerce searching for fish shares would scarcely set alarm bells ringing.
Besides that some fishing vessels, which ostensibly make their residing from the world’s bountiful marine life, have been behaving very oddly lately.
Noticed by the unflinching gaze of a satellite-based vessel monitoring platform, boats from the Russian fishing fleet appeared fully targeted on a distinct kind of prey.
Nice shoals of mackerel and herring will need to have handed one boat by in April 2023, as an example, as she probed far deeper into the inky depths.
Approaching from the north, close to the Faroe Islands, the trawler abruptly modified course simply as she reached the precise latitude of Atlantic Crossing 1 – a telecommunications cable which offers an important undersea hyperlink between the US, the UK, Germany and the Netherlands.
Information collated by World Fishing Watch reveals how, after initially veering east, the vessel doubled again on herself ten instances alongside a 15-mile size of the cable.

In all, she spent eight hours within the space, together with a half-hour interval when she slowed to fewer than two knots.
Earlier than heading north once more the next day, the info seems to point out the trawler making an identical manoeuvre above a second, now decommissioned, telecoms cable.
In one other instance, in February 2025, a Russian fishing vessel crossed the transatlantic Hibernia Categorical cable on a number of events, as soon as travelling at underneath two knots for 42 minutes in shut proximity to the subsea line.
On one other event, she was recorded travelling slowly alongside the route of the SHEFA-2 cable, which connects Shetland to the Faroe Islands.
When four-and-a-half years of monitoring knowledge was crunched and cross-referenced with nautical charts displaying the areas of undersea cables, it revealed an astonishing image: greater than 500 incidents the place 17 totally different Russian trawlers have both hovered above very important communications cables linking Britain with Europe and the US or adopted their routes precisely for miles.
The evaluation, first revealed by the Every day Telegraph, suggests the deliberate use of Russian business trawlers as spy vessels to map the exact areas of fibre-optic cables carrying billions of kilos value of financial exercise each day alongside the seabed.
Whereas the cables’ normal routes are broadly identified, this precision monitoring – most definitely utilizing subtle sonar tools – would furnish Russia with the correct intelligence wanted to launch a focused assault in a future battle with Nato.
Such a transfer would danger paralysing the UK by disrupting banks, hospitals, the transport community and cell phones, since these cables carry the overwhelming majority of telecoms knowledge overseas.
Greater than 60 subsea cables – many mendacity within the waters round Shetland – carry 99 per cent of Britain’s web knowledge, which is significant to the UK financial system.
When the story broke, a Nato supply confirmed to The Telegraph: ‘We’re completely conscious of what Russian civilian fishing ships are as much as and the place. A few of these ships have by no means seen a single fish on their deck.’
And but, the monitoring workout routines haven’t stopped. There have been latest sightings of Russian tankers idling for days over the FLAGS and Frigg pipelines, which carry essential fuel provides ashore on the St Fergus fuel terminal in Aberdeenshire.
The revelations elevate the unpalatable prospect that the Kremlin has been finishing up subterfuge on the excessive seas underneath the noses of the Royal Navy and in defiance of repeated warnings by the British authorities.
The rising significance of undersea infrastructure prompted a parliamentary report final 12 months to warn of safety vulnerabilities in areas together with transport and provide chains, monetary providers and fee methods.
It has additionally heightened fears over simply how uncovered Scotland’s outlying island communities may very well be to the Russian menace, in a chilling echo of the darkish days of the Second World Warfare. Simply as in 1940, it’s the Shetlands which have come into sharp focus.

Then, there have been actual considerations that the islands may very well be attacked after Hitler invaded Norway. Defences have been constructed, troops have been mobilised, able to repel.
Now there are renewed calls to bolster their defences amid elevated detections of Putin’s shadowy ‘fishing fleet’.
Shetland holds a singular mixture of property which might make it a Russian goal.
In addition to hyperlinks to the SHEFA-2 cable, the islands are residence to the large Sullom Voe oil and fuel terminal. There are additionally fears that the £30million SaxaVord Spaceport, on the archipelago’s most northerly outpost of Unst, is on the Kremlin’s radar.
There’s mounting concern at Russia’s more and more brazen behaviour: final week, three senior Tories, shadow defence spokesman James Cartlidge, shadow power secretary and shadow Scottish secretary Harriet Cross, voiced their disquiet in a joint letter to the UK Authorities urging it to behave.
In it, they demanded all subsea cables and power pipelines, together with North Sea power infrastructure, ought to be handed precedence ‘crucial nationwide infrastructure standing’ to discourage hostile states.
Ms Cross mentioned: ‘Scotland is on the frontline of the rising threats from states resembling Russia and China.
‘Power safety is nationwide safety, and reviews of vessels from these hostile nations working near very important pipelines off our coast ought to set alarm bells ringing for Labour ministers.’
She added: ‘These pipelines carry the fuel that thousands and thousands of households and companies depend upon. Any disruption would have catastrophic and doubtlessly long-lasting penalties.’
Final week, First Minister John Swinney accused the UK Authorities of leaving ‘Scotland’s huge shoreline dangerously uncovered’.
Pinpointing the waters off Shetland, he mentioned: ‘I don’t assume we’ve obtained practically the presence in these areas that we require right this moment.’
Comparable feedback he made on the SNP social gathering convention, nonetheless, have been angrily denounced by Defence Secretary Wes Streeting as ‘irresponsible and unfounded’.
However in uncommon cross-party unity, veteran Liberal Democrat MP Alistair Carmichael, whose constituency covers Shetland, insisted the world had modified sufficiently that it was time the UK Authorities re-established a ‘everlasting and devoted’ navy presence in close by waters.
‘By way of the years of the Chilly Warfare, the RAF radar station at SaxaVord in Unst was the front-line of our nation’s defences to the north,’ he mentioned. ‘That was drawn down 20 years in the past.’
Putin’s curiosity within the area has elevated lately
He added: ‘The Excessive North is quickly turning into one of the vital vital arenas for the UK’s political and navy pursuits and the Northern Isles are the gateway to that.’
He advised BBC Radio Scotland’s Breakfast programme: ‘That is one thing we do must be taking significantly.
‘We’re not anticipating an imminent drawback right here however this can be a time the place the Authorities is already telling us that we must always all be maintaining baked beans and a torch in a cabinet.’
This was in reference to Mr Streeting urging the general public to stockpile meals, bottled water and money in preparation for widespread shortages and disruption from cyberattacks and emergencies.
Mr Carmichael mentioned full-time command ought to be restored to the island and ‘low’ numbers of reservists boosted or it might danger sending the fallacious sign.
He pointed to a number of latest suspicious incidents within the Baltic Sea the place underwater cables have been broken or fully minimize.
Since Finland joined Nato in 2023, its telecoms cables within the Baltic Sea have been broken a number of instances. Russian business vessels have been implicated in a number of of those.
On Thursday, the Russian captain of a freighter was jailed for three-and-a-half years by a Finnish courtroom for intentionally dragging his anchor over a cable owned by a Finnish telecoms firm.
Mr Carmichael mentioned the suspicion is Moscow has been eager to ‘ship a sign to the Finnish authorities’ about its hyperlinks to Nato.
He added: ‘That is how Russia will see this stuff; Russia appears on the alerts we ship and if they are saying we don’t assume there’s any risk right here, that we’re not susceptible, then they may learn these alerts and will in some unspecified time in the future sooner or later act accordingly.’
The Ministry of Defence (MoD) has burdened it’s ‘clear-eyed in regards to the risk Russia poses’ and has strengthened its functionality to reply quickly when wanted.
‘Clear-eyed solely takes you thus far in a scenario like this,’ countered Mr Carmichael, mentioning that final 12 months alone, there have been two ‘catastrophic outages’ when the cables connecting Shetland to the remainder of the UK have been damaged.
On one event it took greater than two weeks to get full providers restored to the group.
In 2022, Russia’s Nord Stream oil pipelines have been sabotaged, leaving the Kremlin swearing revenge. Weeks later, the cables connecting Shetland to the Faroes after which with the Scottish mainland have been minimize in fast succession, inflicting mayhem and crippling providers.
Though a police investigation later dominated the harm was most definitely brought on by a fishing vessel dredging within the space, it has been noticed {that a} Russian analysis vessel, the Boris Petrov, had additionally been close by shortly beforehand.
Whether or not or not Russia was concerned in any of those incidents, they reveal how fragile the cables are and the devastating results of any harm.
Mr Carmichael mentioned: ‘The entire of the UK will not be adequately protected – that could be a pretty broad political consensus. That’s why we’re trying, with the help of all events within the Home of Commons, to extend defence spending at scale and pace.’
A unit of 9 P-8A Poseidon plane is presently based mostly at RAF Lossiemouth, Moray, tasked with monitoring Russian vessels within the North Sea and North Atlantic.
Nonetheless final 12 months the Yantar, a Russian spy ship, directed a laser beam at an RAF maritime patrol plane despatched to trace it.
The UK additionally has just one ship devoted to repairing any sabotage to undersea cables. The CS Sovereign, based mostly in Dorset, is because of go away service by 2030.
In a bid to quell considerations, ministers final week set out proposals in a White Paper to make assaults on subsea cables a felony offence leading to a prolonged jail time period.
Mr Carmichael, for one, is sceptical of such an strategy: ‘If Russia is keen to ship folks armed with [the nerve agent] Novichok into Salisbury then they don’t seem to be going to be deterred by the specter of ending up in a UK courtroom,’ he advised The Sunday Instances.
He added: ‘This isn’t an issue that’s going to be solved by well-meaning laws and regulation. We want higher safety and resilience.’
The Royal Navy has ramped up its response. In July, Royal Navy warships and helicopters elevated monitoring of Russian exercise in UK waters and the North Atlantic by 1 / 4.
A WW1 artillery gun, a reminder of Shetland’s significance in defending the UK’s shores
With the UK already in Putin’s crosshairs because of its backing of Ukraine towards Russia’s conflict, the Kremlin’s curiosity in Shetland might nicely have been heightened by its entry into the area race.
Solely final month, the UK Authorities introduced a £30million funding in SaxaVord Spaceport, as a part of a brand new £7.8billion area technique.
Managed by the Danish-born billionaire Anders Holch Povlsen, Scotland’s richest man, SaxaVord has permission for as much as 30 rocket launches a 12 months.
Asserting the funding, Scottish Secretary Douglas Alexander boasted that Scotland already builds extra satellites than some other European nation, including: ‘SaxaVord is poised to ship as much as three quarters of the continent’s orbital launch slots.’
That can inevitably label it a geopolitically strategic asset. As such, Mr Carmichael mentioned: ‘The Russians will need to know all about it. Not all interference shall be about defence. Numerous it is going to be round business pursuits.’
Defence analyst George Allison, editor of the UK Defence Journal, mentioned it was clear Shetland’s ‘strategic relevance is rising’ given society’s near-total reliance on the web.
However he mentioned the UK’s defence mannequin doesn’t depend on completely defending each level on the map with mounted forces however moderately on ‘surveillance, early warning, speedy response functionality, and alliance reinforcement.
‘So the vulnerability will not be that Shetland is defenceless in a conventional sense, however that it sits close to strategic routes and infrastructure which are more and more central to Nato planning. The danger is about disruption and strain.’
It’s understood there was no latest escalation in risk ranges round SaxaVord.
A MoD spokesman mentioned: ‘By way of the UK-led Joint Expeditionary Drive, we’re main allied exercise throughout the Excessive North, strengthening Nato’s northern flank and rising our capacity to reply quickly to rising threats.
‘This authorities can be investing within the capabilities wanted to satisfy these threats, with £1.5billion backing Atlantic Bastion to ship a next-generation Hybrid Navy and an additional £330million to strengthen the safety of crucial undersea infrastructure.’
In the meantime, Shetland stays caught up in a tense sport of maritime cat and mouse.
And the ghost trawlers nonetheless circle, fishing for data in an unlimited ocean of our non-public knowledge.
