The war in Ukraine has exposed how vulnerable underwater infrastructure really is. Pipelines, cables, and ports form the backbone of modern economies — and therefore prime targets. In response, German company Euroatlas has developed a new generation of autonomous underwater vehicles: the Greyshark. Small, silent, and intelligent, but most importantly capable of operating in swarms — a potential gamechanger beneath the surface.
A silent guardian beneath the waves
The Greyshark is designed for long-endurance underwater surveillance. Unlike traditional remotely operated vehicles, it can function fully autonomously. With a range of over 1,000 nautical miles and a cruising speed of around 10 knots, it can patrol for weeks without human intervention. Similar systems are being developed globally, including the Manta Ray in the United States.
What makes the system unique is its ability to remain dormant on the seabed — undetected — and activate when needed, for example when suspicious activity is detected. It combines the patience of a trap with the awareness of a surveillance system.
Swarm intelligence
Multiple Greysharks can operate together, sharing data through secure underwater communication. This allows them to cover large areas and coordinate detection and response. Real-time reporting enables faster situational awareness than traditional systems.
Advanced sensors and stealth
The platform integrates sonar, cameras, and electromagnetic sensors to detect threats and monitor infrastructure. Its electric propulsion and non-metallic structure make it difficult to detect, giving it a major advantage in stealth operations.
Conclusion
The Greyshark represents the next step in underwater defense: autonomous, scalable, and persistent. As threats to critical infrastructure grow, systems like this could become essential in securing Europe’s underwater networks.
