Chinese Researchers Warn Cheap UUVs Threaten Cables Carrying 99% of Global Data

Summary
Chinese military researchers said inexpensive uncrewed underwater vehicles are lowering the barrier to undersea warfare and putting the cable network that carries 99% of intercontinental internet data at greater risk.
About 1.7 million kilometers of submarine fiber-optic cables support roughly $10 trillion in daily cross-border financial activity, yet the network already suffers 150 to 200 faults a year.
The researchers argued AI-enabled UUVs could stay submerged for weeks, avoid detection and operate in coordinated “wolf packs” to patrol cable routes, search targets and support wider maritime missions.
Their warning also targeted Aukus, whose May agreement on UUV development they cast as building a routine seabed monitoring network under the banner of cable protection.
Recent Red Sea cable damage and the 2022 Nord Stream sabotage have sharpened concern over seabed infrastructure, though the International Cable Protection Committee says accidental damage still causes most cable failures.
