EXTENSEE – Multi-domain Drone Operator for Defence & Maritime Security

EXTENSEE is a European operator specializing in the deployment of aerial, maritime, and underwater drones for defence, maritime security, and the protection of critical infrastructures.
We provide turnkey solutions combining operations, maintenance, data exploitation, and training.

Built on strong military and aeronautical experience, EXTENSEE delivers high-performance ISR capabilities designed to operate in the most demanding environments: open sea, remote zones, sensitive areas, and European operational frameworks (e.g., EMSA missions).

We integrate and operate best-in-class systems such as the Flexrotor and autonomous maritime platforms, and we support governmental entities in creating or expanding their drone units with dedicated procedures, training, and operational assistance.

Headquartered in Hauts-de-France, EXTENSEE is fully embedded in Europe’s defence and maritime industrial ecosystem.
