Autonomous Systems: Land & Sea: France signs Naval Group for combat UUVBackground
Steeris OnBoard is an autonomous decision-making system from Naval Group. It will steer the French Navy's combat underwater vehicle demonstrator, signed with the DGA on 3 November 2026, under human supervision.
Naval Group says the system lets a vehicle carry out long missions without continuous remote control, including when communications are limited. It revises the mission plan from environmental and tactical information and responds to equipment failures.
It is the on-board kit of Naval Group's Steeris mission management system, which the company describes as drone-agnostic and able to work with existing combat management systems.
