Germany's GREYSHARK Underwater Drone Enters Series Production With Government Orders
EUROATLAS and EvoLogics begin series production of GREYSHARK underwater drones, with European government orders and deliveries planned for 2026.
German defense technology companies EUROATLAS and EvoLogics have announced the start of series production of their GREYSHARK autonomous underwater vehicle, with orders already secured from European government customers and initial deliveries scheduled before the end of 2026.
The companies presented the first production-standard vehicle at Euronaval 2026 in Paris on November 3, marking the transition from prototype development to industrial manufacturing.
GREYSHARK is designed for maritime surveillance, intelligence gathering, mine countermeasures and the protection of critical underwater infrastructure.
GREYSHARK Offers 300 Nautical Miles of Range
The approximately six-meter-long autonomous underwater vehicle features a streamlined hull designed for extended operations in demanding maritime environments.
According to the manufacturers, GREYSHARK has a cruising speed of 10 knots and can achieve a range of approximately 300 nautical miles at four knots in its battery-powered configuration.
Operational endurance is estimated at three to five days, depending on the mission profile. The companies are also developing a fuel-cell-powered version intended to provide significantly greater range and endurance.
The vehicle is designed to operate autonomously, using onboard sensors and mission software to conduct reconnaissance, examine underwater objects and monitor maritime areas.
A particularly important feature is the ability for multiple GREYSHARK vehicles to cooperate through an underwater communications network.
Using EvoLogics' encrypted S2C acoustic communications technology, the vehicles can exchange reconnaissance information and coordinate operational tasks, including the investigation of detected objects.
European Government Customers Place Orders
EUROATLAS and EvoLogics confirmed that European government customers have already placed orders for the system, although neither company identified the buyers, disclosed contract values or provided production quantities.
First deliveries are expected before the end of 2026.
The industrial milestone follows the initial GREYSHARK prototype presentation at Euronaval 2024 and subsequent development and testing.
EUROATLAS, based in Bremen, contributes naval systems engineering, power electronics and platform integration expertise. Berlin-based EvoLogics specializes in maritime robotics, underwater communications, positioning and autonomous systems.
Underwater Infrastructure Protection Drives Demand
The move into series production comes as European navies increase their investment in surveillance and protection of subsea infrastructure, including communications cables, pipelines and offshore energy installations.
Autonomous underwater vehicles offer an alternative to relying entirely on crewed ships for persistent monitoring and inspection missions, particularly across large maritime areas.
The market is also attracting companies in Central and Eastern Europe. Latvia's SUBmerge Baltic is expanding production of underwater drones for security, infrastructure and defense applications.
For EUROATLAS and EvoLogics, the immediate industrial challenge will be delivering the first contracted systems and demonstrating that GREYSHARK can be manufactured and supported at scale.
The announcement represents a transition from development to commercial and government deliveries, although the scope of the initial orders remains undisclosed.
