NATO is installing its future AI center in Brittany, at the heart of the French cyber ecosystem.

Comcyber, DGA, AMIAD, and soon NATO. The Rennes metropolitan area already hosts the command of the army's cyber defense (Comcyber) and the "information mastery" pole of the General Directorate of Armaments. It mainly hosts the Ministry Agency for Defense Artificial Intelligence (AMIAD), directed by Bertrand Rondepierre. It will welcome a new major tenant. The Atlantic Alliance is about to create an excellence center (CoE) entirely dedicated to artificial intelligence, and it is Rennes that has been selected to host it. About fifty employees are planned. France is the only candidate country to host this future organization.

How France secured the dossier in a year

The project dates back to the summer of 2025, when Sébastien Lecornu, then Minister of the Armed Forces, had introduced the idea following the Summit for AI Action organized in Paris in February 2025 at the initiative of Emmanuel Macron. Since then, the roadmap was prepared by Rondepierre on the French side and presented to the NATO Military Committee by the Allied Command Transformation (ACT), led by French Admiral Pierre Vandier. The final decision is subject to a silence procedure: if none of the other 31 member countries object, the center will be formally launched in June. Operations are set to begin in May 2027.

General Cyril Carcy, the French military representative to NATO, has started a tour of capitals to convince his counterparts to join the project and contribute financially. Several powers have already expressed their interest. The choice of Rennes is no geographical coincidence. Orange, Airbus, Thales and Sopra Steria have established the direction of their subsidiaries dedicated to cyber defense, forming an industrial ecosystem ready to feed an allied research center on military AI.

Three NATO excellence centers in France, zero American favoritism

By adding Rennes to Toulouse (space excellence center, inaugurated in January 2026) and Lyon (air operations), France will align three NATO excellence centers on its territory, as many as Germany. The Alliance currently has 30 and plans to reach 32 by 2027. Italy is preparing a center dedicated to deep-water navigation, announced for next month in Rome. Turkey and Portugal each push a project for a center on drones and anti-drone operations.

The timeline also tells another story. While Paris multiplies excellence centers on its soil, Washington has just approved the closure of CJOS (Combined Joint Operations from the Sea), the excellence center dedicated to joint operations from the sea, based in Norfolk, Virginia. The headquarters of the excellence centers did meet last week at the NATO headquarters in Brussels to review this reorganization. The movement is symmetrical: the United States is disengaging from certain Alliance structures, and France is taking the lead.

Rennes is not only becoming the French capital of cyber defense. With Comcyber, the DGA, the AMIAD, and soon a NATO center on AI within a few kilometers, the Brittany metropolis is positioning itself as the main European hub for defense AI. All of this at a time when the Europeanization of the Alliance is no longer a slogan, but a measurable budgetary and institutional movement.
