flag NATO is testing German GreyShark drones in the Baltic Sea to protect undersea infrastructure and counter Russian threats.

flag NATO nations are testing German-developed GreyShark underwater drones in the Baltic Sea to protect undersea cables and pipelines, detect submarines, and clear mines amid rising security concerns. flag The silent, autonomous penguin-shaped drones, including long-range Foxtrot and battery-powered Bravo models, can operate up to four months without human input and adapt missions independently. flag They are being evaluated by several European NATO members following suspicious cable damage in late 2024, with officials citing Russia’s hybrid warfare tactics as a concern. flag The drones, part of a broader NATO push for affordable, mass-producible unmanned systems, are seen as vital for countering threats in the undersea domain, where stealth remains a key advantage.
