Maritime autonomy trials

NATO reports Task Force X-Arctic integration trial at REPMUS

ACT says nearly 300 capabilities connected to its digital architecture during maritime experimentation in Portugal.

NATO Allied Command Transformation reported on 24 September that Task Force X-Arctic had tested its orchestration architecture at scale during REPMUS 2026 in Portugal. ACT says nearly 300 capabilities connected to the project's digital backbone. That figure describes connected capabilities, not a delivered fleet of 300 drones.

The experiment combined shared data, command-and-control and mission-planning software to coordinate contributed systems. NATO says the architecture repeatedly reassigned tasks as conditions changed, with people retaining responsibility and control.

What remains to be demonstrated

This is NATO's account of an experiment, not operational acceptance or an acquisition announcement. Planned remote-connectivity and Arctic trials remain further steps. Results in Portuguese waters alone do not demonstrate sustained performance in polar conditions.

The development concerns coordination across systems and suppliers. It is separate from the individual WAM-V trials already covered in our news archive.
