Shark-shaped submarine robot to guard 800,000 miles of subsea cables

A German defense technology company, Euroatlas, has developed an autonomous underwater robot named Greyshark to patrol, map, and protect the global subsea cable network, which spans approximately 800,000 miles and carries over 95% of global internet traffic and $10 trillion in daily financial transactions. Designed for long-duration reconnaissance and surveillance in both coastal and deep-water environments, the shark-shaped robot operates autonomously using advanced sensors and AI-driven mission capabilities. It can work collaboratively with other Greyshark units, communicating securely underwater, remaining dormant on the seabed until detecting unusual activity near critical infrastructure, such as suspicious vessels. The introduction of Greyshark comes amid rising geopolitical tensions and increased incidents of subsea cable damage, particularly in regions like the Baltic Sea. NATO has responded with initiatives like Baltic Sentry to enhance surveillance and protection of these vital cables, including increased patrols and actions against vessels suspected of tampering.
