French military unveils AI-driven command system

General Fabien Mandon, Chief of Staff of the Armed Forces (CEMA), introduced Project Arcadia during a parliamentary hearing on October 8, 2026. Arcadia is a future command software for the French armed forces, designed to rely heavily on artificial intelligence.

Arcadia aims for European technological independence

Arcadia was presented to the Defense Journalists Association on September 29, 2026, at Mont-Valérien, near Paris. The software is intended to integrate all military data without relying on American publishers such as Palantir. General Mandon emphasized the need for this due to the U.S. technological influence on NATO, urging France to avoid dependence on American solutions and instead pursue a European alternative for AI and data control.

Arcadia functions as a unified military command system

Arcadia, described as a C2 (command and control) system, allows military staff to track the position of their units, gather intelligence, and prepare orders. The Defense Digital Commission (CND) calls it a "sovereign inter-service command system centered on data and boosted by AI." It is intended to serve the Army, Navy, and Air and Space Force, replacing the fragmented computer systems currently used by the Ministry of Defense.

Arcadia integrates multiple military systems into one platform

The need for such a system arose from the Ministry of Defense’s current use of 1,500 to 2,000 different information systems. Arcadia aims to unify these into a single, centralized platform, referred to as a "C2 store," similar to app stores like Google Play or the App Store. The CND describes the system as "open, secure, and interoperable."

Arcadia developed with input from military personnel

General Mandon explained that Arcadia was developed in collaboration with operational personnel and programmers to ensure it meets the needs of end users. He cited a use case from the recent crisis in the Red Sea and the Strait of Hormuz, where AI reduced complex manual tasks to under a minute of calculation. Arcadia is positioned as a French alternative to Maven, the Palantir software used by NATO.

Arcadia builds on previous military AI efforts

The CND, established in September 2025, is leading the development of Arcadia under the leadership of General Erwan Rolland. Arcadia succeeds SIA C2, an abandoned program, and builds on Artemis.IA, a data processing platform developed by Athea, a joint company of Thales and Atos. Arcadia uses a language model called Berthier, similar to ChatGPT, and was developed with Thales, Safran, Airbus, and Mistral AI.

Arcadia gains interest from European allies

General Patrick Justel of the Army noted that the United Kingdom, Germany, and Poland are interested in Arcadia. The Chief of Staff of the Armed Forces confirmed that France has shown the system to NATO and received signs of interest in Europe, with many partners viewing it as an alternative to Maven. Arcadia is one of several military AI projects by the ministry, expected to enter full operational service by the end of 2027.

France advances other military AI projects

The CND also showcased a sovereign foundation model trained on the military supercomputer Asgard, capable of detecting and identifying land vehicles. The military has its own conversational assistant, GenIAI.intradef, since the beginning of 2025. The ministry has also announced a partnership between its defense AI agency and Mistral AI, the French startup that has allied with the German Helsing to develop battlefield models.

Thales proposes AI-based software to NATO

On September 17, 2026, Thales proposed its AI-based command software, HexaForce, to NATO, leveraging insights from Arcadia and Artemis. This move highlights the growing interest in French-developed AI solutions within the broader European and NATO military community.
