France and Germany pledge sovereign rival to Palantir military AI

France and Germany signed a joint declaration on Friday to develop a European sovereign digital backbone, naming France’s Arcadia command-and-control platform as the foundation for a homegrown rival to Palantir’s military AI software. The agreement follows talks between Emmanuel Macron and Friedrich Merz and covers data-centric security, artificial intelligence, and cloud solutions.

For European tech firms, the pledge marks a potential inflection point in a defence market historically dominated by American suppliers. Both countries have already taken decisive steps to sever existing ties with Palantir. France’s DGSI announced in June it was replacing the American firm with ChapsVision’s ArgonOS, just six months after renewing its contract. Germany’s BfV made the same switch to ChapsVision, and the Bundeswehr entirely excluded Palantir from its defence cloud procurement.

The commercial implications are significant. By guaranteeing state-level demand for sovereign alternatives, Paris and Berlin are attempting to create the scale necessary for European tech companies to compete. A top NATO commander recently told Politico that the alliance relies on Palantir’s Maven software for battlefield data processing because no real European alternative exists. Friday’s declaration is a direct answer to that gap.

Beyond software, the joint statement outlined broader industrial cooperation. France, Germany, and the UK will examine developing long-range weapons with a 2,500-kilometre range, drawing on the capabilities of ArianeGroup. The Franco-German MGCS tank programme, designed to replace the Leopard 2 and Leclerc, will launch a dedicated research programme focused on autonomous driving, sensors, and battlefield networking.

Notably, the troubled FCAS next-generation fighter jet project was absent from the text. Rather than pushing the struggling programme, the two nations agreed to create a "European collaborative combat standard" to ensure fighter jets and drones from different member states can communicate on the battlefield.

Palantir CEO Alex Karp recently dismissed Germany's refusal to consider his company as "conversations about witchcraft" in an interview with Bild, arguing the software is proven on every serious battlefield. That argument has failed to shift Berlin's position.

The sovereignty debate in Europe has moved beyond whether American technology works. The pressing question is whether relying on a US company for sensitive military infrastructure is viable when transatlantic relations can no longer be taken for granted. Turning Friday's political declaration into functional, deployable software remains the formidable challenge ahead.
