France is preparing to test its own AI-supported combat command system in a NATO exercise starting Monday, according to Defense News (source in English). AI-based combat systems help optimize decision-making processes and target identification.
Developed in collaboration with French companies, Arcadia is positioned as a European alternative to the AI platform Maven, developed by US defense technology contractor Palantir, which NATO currently uses.
Seeking Sovereignty in European Defense Technologies
The system named Arcadia will be deployed during NATO’s Coalition Warrior Interoperability Exercise, held in Poland from June 8 to 26, according to French Army Deputy Chief of Staff General Patrick Justel. French companies involved in Arcadia’s development include Mistral AI, Safran, Thales, and Airbus.
Arcadia is part of Paris’s broader initiative to strengthen Europe’s technological sovereignty in defense. NATO began using the Maven Smart System, derived from the Pentagon’s Project Maven initiative, in 2025. The system integrates vast amounts of field data to enable faster decision-making and target detection.
However, French officials have expressed concerns about dependency on non-European systems. Justel said at a press conference on Thursday, as reported by Defense News, that Arcadia is "our response to Maven," adding, "The question arises whether we should adopt Maven unquestioningly or seek other solutions."
Moving Away from Dependence on Palantir
European governments increasingly want to reassess their agreements with Palantir, which has been controversial due to its use in military operations, mass surveillance, and migration policies.
Dutch Defense State Secretary Derk Boswijk said in the House of Representatives this week (source in English) that a "fully-fledged alternative" to Palantir should be ready within two years. The Dutch government is working on a "two-pronged policy to reduce dependency" on the company to enable independent action and find a European alternative as soon as possible.
Meanwhile, Germany announced, according to Reuters, that it will not sign contracts with any US companies in this field, including Palantir.
Thomas Daum, head of Germany’s cyber defense unit, reportedly said this week (source in English), "As much as we are interested in this functionality for our own database, it is simply unthinkable at present to grant industry workers access to the national database."
Interoperability Debates Within NATO
France has already tested Arcadia in exercises in Romania and domestically, stating that the system is designed to comply with NATO’s Federated Mission Networking (FMN) standards, a key framework for interoperability among allied forces.
Although Palantir claims its system complies with FMN principles and is progressing toward full certification, interest in a European-made alternative is growing. Justel said, "When we talk to our European partners, we always get the same response: 'We used Maven because there was no other option for now, but if European countries develop an alternative, we would prefer it.'"
Reports indicate Denmark is seeking local solutions to replace its seven-year contract with Palantir. A More Resilient, Decentralized System Arcadia is designed as a decentralized system connecting command centers to field servers via a mesh network, whereas Maven features a more centralized architecture.
French officials say the decentralized approach increases resilience by allowing operations to continue even if parts of the network go offline.
