Prime platforms
Capable but costly and slow, built in small batches.
Mission
Europe's coastlines have become one of its most contested spaces — migration, smuggling, illegal fishing, and the protection of undersea cables and pipelines. The waters that need watching have grown; the crewed ships available to watch them have not. Persistent presence wins. We build the autonomous vessels that make that presence affordable — designed, built, and controlled in Europe, for European sovereignty.
How We Build
Mass production from day one
We design for manufacturability, not just performance. A surveillance fleet only matters if a customer can buy it in numbers.
NATO interoperability by design
Our vessels plug into the command-and-control systems allied forces already use. A node in an existing operational picture, not a standalone gadget.
What We Stand For
Credibility over hype
Real capability, demonstrated. No vapour, no overreach.
Sovereignty
Designed, built, and controlled in Europe, for European forces.
Scale
Engineered for manufacture, so a fleet can actually be fielded.
Interoperability
A node in the operational picture, not a standalone gadget.
Contact
Field the fleet that watches the water.
For defense procurement, investment, and partnership enquiries. We respond to credible, qualified contacts.
