ON Nov. 15, 2024, a Chinese­flagged cargo ship called the Yi Peng 3, laden with min­eral fer­til­izer, left the Rus­sian port of Ust-Luga and pushed into the Baltic Sea. Two days later, the ship crossed over an under­sea com­mu­nic­a­tions cable con­nect­ing Sweden and Lithuania. The line went silent. Less than 24 hours later, the Yi Peng 3 cruised past the only com­mu­nic­a­tions cable con­nect­ing Fin­land with Ger­many, and it too went dark.

European invest­ig­at­ors soon dis­covered both sub­sea cables had been phys­ic­ally severed and that the Yi Peng 3 was at the scene of both incid­ents. It seemed like sab­ot­age, but little could be done it. The coun­tries impacted could only ask China for help with the invest­ig­a­tion, which was declined. The ship slipped away.

Since the Yi Peng incid­ent, insi­di­ous sab­ot­age has only become more pre­val­ent around the world, and the pace is pick­ing up. Mys­ter­i­ous fires have swept weapon plants in Esto­nia, Ger­many, Poland, the Czech Repub­lic and Bul­garia. On Aug. 20, Romanian air force scrambled two F-16s to blow up an intrud­ing robotic boat loiter­ing near a Black Sea gas plat­form with hun­dreds of work­ers on board. And in Septem­ber the FBI charged five people work­ing for Rus­sian intel­li­gence ser­vices who were soli­cit­ing arson and murder around the world, includ­ing in the United States.

Secur­ity experts call these “hybrid attacks,” and they are get­ting more com­mon and more viol­ent. They are per­petu­ated in a gray zone between war and dip­lomacy, where shady act­ors are used to cre­ate deni­ab­il­ity for a nation’s pro­voc­at­ive actions.

Now comes author Elisa­beth Braw’s new book “Under­sea War: The Battle to Con­trol the Cables and Pipelines That Con­nect Our World,” to enlighten read­ers on another vul­ner­ab­il­ity to worry — the under­wa­ter spa­ghetti bowl of pipelines and cables that sup­port the mod­ern world.

THE globe is stitched together with a net­work of under­wa­ter com­mu­nic­a­tion cables and energy pipelines. There is an estim­ated 20,000 miles of sub­sea pipelines world­wide car­ry­ing pet­ro­leum, crude oil and nat­ural gas, and a mil­lion miles of garden hose-size oceanic com­mu­nic­a­tions cables in ser­vice glob­ally.

Braw some­what gran­di­osely calls this “the Under­sea King­dom,” but makes a good case for its import­ance. Cables down there trans­mit the world’s data, includ­ing tril­lions in daily fin­an­cial trans­ac­tions, and sub­sea pipelines provide fuel to entire con­tin­ents.

“Behind every email, credit card pay­ment and Zoom call is an ocean worker,” Braw writes. Under­wa­ter pipelines “keep the lights on, heat the house.”

Yet this infra­struc­ture is reach­able by any bad guy with a civil­ian ship and a deep enough anchor. Mak­ing mat­ters worse, soft tar­gets under­wa­ter are vul­ner­able to attacks that are hard to attrib­ute and there­fore more tempt­ing to try. “If under­sea dis­aster struck and life had to revert to life circa 1858, people would def­in­itely notice,” Braw explains, as close to a chuckle as the book attempts.

BRAW, a senior fel­low with the Atlantic Coun­cil’s Scow­croft Cen­ter for Strategy and Secur­ity, may be as dry as the topic is wet, but she’s cer­tainly an expert. She effi­ciently chron­icles the under­wa­ter mis­be­ha­vior of Rus­sian and Chinese ships, which have ducked behind a lack of mari­time laws and dip­lo­matic bravado to sab­ot­age under­sea cables and pipelines with near impun­ity.

The exist­ing legal frame­work that gov­erns these cables is rooted in paper­work signed dur­ing the 1884 Paris Con­ven­tion. It author­izes vir­tu­ally no enforce­ment options if the ves­sel in ques­tion is registered to another nation.

“Under­sea War­fare” provides sober­ing real-world examples the adven­tures of repeat offend­ers such as the NewNew Polar Bear, implic­ated in anchor-attacks on a com­mu­nic­a­tion line and a nat­ural gas pipe in Finnish waters, and the nowno­tori­ous Yi Peng 3.

Per­haps the most infam­ous attack on this sea-bound empire was the Ukrain­ian sab­ot­age of the all-import­ant Nord Stream pipeline in 2022. Braw treats this incid­ent in a dis­join­ted, frag­men­ted nar­rat­ive, and the book com­pares poorly on this topic to other recent entries such as Bojan Pancevski’s thrill­ing “The Nord Stream Con­spir­acy.”

Still, not every book needs to “read like a thriller,” and “Under­sea War” cer­tainly won’t be con­fused for one. But it is cer­tainly thor­ough, and the risks it presents are no doubt fear indu­cing.

ONE ship can bring life to a stand­still. For example, in 2023 Chinese cargo ships severed the two com­mu­nic­a­tion cables that con­nec­ted Taiwan’s dis­puted islands of Matsu to the rest of the world. In an instant, the inter­net went down. “Sud­denly, inform­a­tion could only be obtained by word of mouth.” Hos­pit­als were forced to rely on gen­er­at­ors. “Digital pay­ments could not be pro­cessed. The back­bone enabling mod­ern life was simply not there any­more.”

Invest­ig­at­ors quickly determ­ined which ships were respons­ible. The boats were eas­ily loc­ated, but they had left Taiwanese waters, and, thanks to the archaic laws gov­ern­ing the sea, the Taiwanese coast guard “didn’t have the author­ity to detain them.”

The UN law of the seas says that invest­ig­a­tions into dam­age to under­wa­ter pipelines and cables are the respons­ib­il­ity of the cul­prit boat’s nation. China, unsur­pris­ingly, was not keen to pun­ish the boats that had cut Matsu off from the world.

Besides present­ing the risks of sab­ot­age, Braw more quietly pos­its solu­tions that could blunt the impact.

The best way to harden this infra­struc­ture from attack is redund­ancy. Adding duplic­ate cables is the best and most com­mon way to safe­guard sub­sea com­mu­nic­a­tion lines. That’s what Braw says hap­pen­ing in the Baltic, around Taiwan and else­where.

The idea that under­sea sab­ot­age might be the start of a global war, rather than a prob­able cas­u­alty, comes up often in Braw’s nar­rat­ive, per­haps a bit too cas­u­ally. In the intro­duc­tion, she even quotes Tom Clancy’s sub­mar­ine thriller, “The Hunt For Red Octo­ber”: “This busi­ness will get out of con­trol . . . and we’ll be lucky to live through it.”

The era of per­sist­ent hybrid war is clearly already upon us, under­sea infra­struc­ture included, and the only good news so far is that it hasn’t yet star­ted World War Three. In August, Ger­man author­it­ies blamed Rus­sia for land­ing explos­ive-laden aer­ial drones at its air­ports, aim­ing at parked civil­ian air­craft used to sup­port Ukraine. Ger­many didn’t invoke NATO’s self­de­fense ral­ly­ing cry, Art­icle 13. No tanks surged to the bor­der of Poland and Lithuania, towards Rus­sia. That’s not to say there’s noth­ing to fret — far from it. The sub­sea vul­ner­ab­il­it­ies cited in “Under­sea War” cer­tainly still exist, and the ten­sions seem to be spill­ing over the bound­ar­ies of law enforce­ment and hybrid war.

In mid-Septem­ber, offi­cials told Reu­ters that a joint NATO oper­a­tion off Nor­way thwarted a Rus­sian sub­mar­ine exer­cise aimed at dis­abling under­sea data cables. Brit­ish sub­mar­ines fol­lowed three ves­sels from the GUGI, the Rus­sian under­sea war­fare dir­ect­or­ate, dur­ing a month-long cov­ert oper­a­tion in the Arc­tic to test a weapon that could cut cables without leav­ing tell­tales, NATO offi­cials said.

Some­where, you can almost hear Braw ringing a bell and declar­ing her Under­sea King­dom already under siege. And for all that mod­ern humans have at stake in the out­come, the battle for it won’t be seen or heard, until the power goes out and the inter­net goes dark. That day, Braw will be able to say, “I told you so.” Only no one will be able to hear it.
