German firm Euroatlas has revealed its latest innovation in underwater surveillance technology: the Greyshark, an autonomous underwater vehicle (AUV) designed for long-distance reconnaissance, patrol, and protection of critical sea areas. With advanced sensor capabilities and the ability to operate autonomously in swarms, Greyshark promises to enhance maritime security operations in ways previously unseen.
The Greyshark AUV is equipped with a suite of high-tech sensors, including sonar, LIDAR, cameras, and electromagnetic detectors, allowing it to identify a wide range of threats—from mines to enemy vessels. What sets it apart is its ability to autonomously patrol and protect designated sea areas, using its swarm capabilities to expand sensor coverage and increase operational efficiency. These AUVs can be deployed either passively on the seabed, where they remain dormant until activated by a critical event, or actively, patrolling areas of interest with specific behaviors defined by operators.
One of Greyshark’s standout features is its encrypted underwater communication system, enabling it to relay real-time intelligence to other Greysharks, vessels, and situational awareness systems. This ensures seamless coordination between multiple units, whether patrolling an area for security threats or monitoring infrastructure such as pipelines, cables, and harbors.
Greyshark is not only equipped for intelligence gathering but also for more active defense measures. A swarm of AUVs can distract and disorient enemy reconnaissance operations, using coordinated active sensors to track and follow specific vessel classes. Its quiet electric propulsion system and non-metallic hull further reduce its detection risk, while its low sonar signature makes it particularly difficult to detect by adversaries.
With a cruising speed of 10 knots and a minimum operational range of 1,000 nautical miles, Greyshark offers unmatched endurance. It integrates easily with existing situational awareness systems, making it a versatile and reliable tool for a wide range of underwater tasks, including mine warfare, infrastructure monitoring, and security patrols. Whether operating individually or as part of a coordinated swarm, Greyshark represents a significant step forward in autonomous maritime defense technology.
