UK, Norway, US Disrupt Russian Deep-Sea Exercise Targeting Svalbard-Norway Cables
Current overview (not historical)
In spring 2026, the United Kingdom, Norway, and the United States tracked and disrupted a Russian deep-sea submersible exercise off the Norwegian coast that simulated deploying weapons against two 1,400-kilometer seabed cables linking Svalbard to mainland Norway. A War on the Rocks analysis says the incident exposed wartime vulnerability of undersea cables and insufficient repair capacity. The author states that the United States lacks a strategy to repair multiple simultaneous cable breaks during war, citing limited cable ships, reliance on global supply chains for spare parts, and unclear insurance and legal status. The article recommends designating undersea cables as critical infrastructure, creating a federal coordination body, expanding the cable-ship fleet, and stockpiling trusted spare parts.

The article warns that submarine cables are vulnerable in wartime and that the United States has no coordinated strategy to repair simultaneous cable cuts across multiple theaters. It highlights limited repair ships, spare-part shortages, insurance risks, and legal ambiguity, urging federal designation of cables as critical infrastructure and funding for an expanded Cable Security Fleet.
