Western governments have been quietly involved in regards to the safety of undersea cables, which carry many of the world’s web visitors, for a few years. However solely lately has the problem come into sharp focus, owing to a collection of murky incidents from the Baltic Sea to the Crimson Sea and a wider realisation that infrastructure, of all types, is a goal for subversion and sabotage.
Throughout Europe, Russian spies and their proxies have attacked Ukraine-linked targets, hacking into water utilities, setting fireplace to warehouses and plotting to strike American army bases in Germany. The concern is that underwater communications might be crippled in a disaster or in wartime, or tapped for secrets and techniques in peacetime. And as America and China joust for affect all through Asia, undersea cables have develop into a vital a part of their competitors.
Greater than 600 lively or deliberate submarine cables criss-cross the world’s oceans, operating for greater than 1.4m kilometres in complete, sufficient to go from Earth to the Moon greater than 3 times, in line with TeleGeography, an information firm. These carry the overwhelming majority of web visitors. To take one instance, Europe is related to America by some 17 cables, largely by way of Britain and France (see map). Greater than 100 cables are broken annually around the globe, fairly often by errant trawlers and ships dragging their anchors.

The difficulty is that it’s arduous to tell apart accidents from sabotage. Take the injury inflicted on the Balticonnector gasoline pipeline and a close-by communication cable within the Gulf of Finland in October 2023. Regional officers suspected the involvement of the Newnew Polar Bear, a Chinese language-owned container ship which had earlier swapped its crew in Kaliningrad, a Russian exclave, and later turned up in Archangel with its anchor lacking. 9 months later, Finnish authorities imagine that the incident was most likely a real accident. Different Western officers proceed to suspect Russian malfeasance.
Under the floor
That’s comprehensible. Russia has invested closely in naval capabilities for underwater sabotage, primarily via GUGI, a secretive unit which operates deep-water submarine and naval drones. “The Russians are extra lively than we have now seen them in years on this area,” warned NATO’s intelligence chief final yr. A report revealed in February by Coverage Trade, a think-tank in London, claimed that since 2021 there have been eight “unattributed but suspicious” cable-cutting incidents within the Euro-Atlantic area, and greater than 70 publicly recorded sightings of Russian vessels “behaving abnormally close to essential maritime infrastructure”. In its annual report in February, Norwegian intelligence mentioned that Russia had additionally been mapping the nation’s essential oil and gasoline infrastructure for years. “This mapping remains to be ongoing, each bodily and within the digital area [and] may develop into vital in a battle scenario.”
The issue isn’t confined to Europe. In February three submarine cables operating via the Crimson Sea have been broken, disrupting the web throughout east Africa for greater than three months. The trigger was most likely a missile strike on the Rubymar, a fertiliser ship, by the Houthis, a Yemen-based insurgent group that has been menacing transport in solidarity with Hamas in Gaza. When the Rubymar was deserted by its crew, later sinking, its anchor is assumed to have dragged alongside the seabed and reduce the cables. In March related disruption occurred throughout west Africa when one other essential cable system was severed off the Ivory Coast, probably as a consequence of seismic exercise on the seabed.
American strategists fear a couple of potential Chinese language menace to cables in Asia, too. Taiwan, specifically, is overwhelmingly depending on undersea cables for worldwide communications, and has a comparatively small variety of terminals, the place they arrive ashore. In a struggle, writes Elsa Kania of the Centre for a New American Safety (CNAS), a think-tank in Washington, the Individuals’s Liberation Military would search to impose an “info blockade” on the island. Severing cables “would virtually actually be a element of that marketing campaign”. In February 2023 a Chinese language cargo ship and a Chinese language fishing vessel have been suspected of chopping the 2 cables serving Matsu, an outlying Taiwanese island, six days aside, disrupting its connectivity for greater than 50 days—although there isn’t any arduous proof of skulduggery.
Cable-cutting may serve broader struggle goals. “One of the simplest ways to carry down the US drone fleet, or certainly to undermine the 5 Eyes intelligence system, which is massively depending on web surveillance,” write Richard Aldrich and Athina Karatzogianni, a pair of intelligence historians, “can be to assault submarine cables.” Struggle video games run by CNAS in 2021 discovered that Chinese language cable assaults “usually resulted within the lack of terrestrial web connectivity on Taiwan, Japan, Guam and Hawaii and compelled these islands to depend on decrease bandwidth and extra susceptible satellite tv for pc communications”. (In distinction, the identical struggle video games discovered that Russia, with restricted specialist cable-cutting models, “couldn’t shortly eradicate the dense cable communications between North America and Europe”.)
Western governments are scrambling to erect higher defences. Their precedence is to grasp what is definitely occurring underwater. NATO states have already elevated air and naval patrols close to essential infrastructure, together with cable routes. In Could the alliance convened a brand new Vital Undersea Infrastructure Community for the primary time, with the goal of sharing extra info between governments and with the non-public corporations which are inclined to function the cables. A “digital ocean idea” in October additionally envisaged “a worldwide scale community of sensors, from sea mattress to area” to determine threats. A European Union initiative is considering a community of “underwater stations” on the seabed which could enable drones to cost batteries and transmit information on what they’ve seen.
As soon as injury happens, repairing it’s arduous. The world has solely 60 or so restore ships, which implies that breaks is probably not mended for months. Many are flagged neither to America nor one in every of its allies, notes Evan D’Alessandro of King’s School London who research undersea cables. The problem can be compounded in wartime, the place Chinese language cable-cutting would deal with closely contested areas close to Taiwan’s shoreline.
Cable-repair ships needed to be escorted by warships within the first and second world wars, observes Mr D’Alessandro. In a Pacific struggle, he notes, America and allied navies would have few spare ships for that process. Partly to mitigate that downside, the Pentagon established a Cable Safety Fleet in 2021, during which American-flagged and crewed cable-ship operators obtained a $5m annual stipend in trade for being on 24 hours’ discover in a disaster and being able to serve in wartime.
The priority is not only sabotage, nonetheless, but additionally snooping. America and its allies know the menace higher than anybody, as a result of for many years they’ve embodied it. Within the Seventies America carried out audacious operations to faucet Soviet army cables utilizing specifically geared up submarines that would place and get well gadgets on the seabed. Because the web went international, the alternatives for underwater espionage rose quick. In 2012 GCHQ, Britain’s signals-intelligence service, had tapped greater than 200 fibre-optic cables carrying cellphone and web visitors, lots of which handily got here ashore on the nation’s west coast. It additionally reportedly labored with Oman to faucet others operating via the Persian Gulf. The lesson—that the route and possession of cables may be very important to nationwide safety—was not misplaced on others.
Certainly, concern of Chinese language espionage is one purpose why America has taken such a eager curiosity in Asia’s quickly rising cable infrastructure. Between 2010 and 2023, about 140 new cables have been laid within the area, in contrast with simply 77 in western Europe. China has develop into an vital participant within the cable spree via HMN Applied sciences, an organization which was beforehand often called Huawei Marine Networks. The agency boasts that it has laid greater than 94,000km of cables throughout 134 initiatives.
In 2020 America, alarmed by this pattern, blocked HMN’s involvement in a proposed $600m cable from Singapore to France, by way of India and the Crimson Sea, often called SeaMeWe-6, by providing grants to competing firms and threatening sanctions on HMN. These would have prevented American corporations from utilizing the cable. That was one in every of at the least six cable offers in Asia disrupted by America between 2019 and 2023, in line with a current investigation by Reuters, a information company.
Hassle in paradise
America’s regional allies are equally eager to curb Chinese language affect. In 2017 a Chinese language effort to attach Australia and the Solomon Islands within the South Pacific was countered by Australia’s authorities, which established an alternate undertaking involving Nokia, a Finnish agency. Australia is now funding two different cables to Palau and East Micronesia, a pair of archipelagoes the place China, America and Australia have jostled with one another for affect lately. These efforts have dramatically slowed China’s cable ambitions. HMN remains to be a minnow in contrast with America’s SubCom, Japan’s NEC Company and France’s Alcatel Submarine Networks, the trio of corporations that dominate the worldwide cable-laying market.
Even with higher undersea surveillance and extra redundancy in routes, the menace is unlikely to abate. Deep-sea cable chopping as soon as required giant naval investments. More and more succesful naval drones are altering that. “The flexibility to function at excessive depths is probably not the only real protect of main powers anymore,” says Sidharth Kaushal of RUSI, one other think-tank. The problem for smaller powers, he says, will usually be figuring out the exact route of cables. That may take years of peacetime surveillance. It’s no surprise, then, that many Western governments would quite maintain such particulars tightly below wraps.
