They have not agreed on whose it should be.
Internal German government notes seen by Politico Europe show Berlin is wary of Arcadia, the French-built Palantir rival. The worry is that adopting it would trade reliance on an American company for reliance on a French one. Chris Lunday and Laura Kayali reported the documents on 3 September. TNW has not seen the notes and has not independently verified them.
The German assessment is blunt. “Engagement with Arcadia must not undermine national efforts to build a sovereign data-integration platform,” it says, according to Politico. The same note accepts that Germany will still have to share information with the French system, so that anything Berlin builds later can work alongside it. What Arcadia is meant to replace Armies now collect far more data than any commander can read. Satellites, radars, drones, electronic sensors and individual soldiers all feed the same picture.
The software that fuses them decides what a general actually sees. NATO bought Palantir’s Maven Smart System in 2025 to do that job. It handles targeting, situational awareness and operational planning. It works.
It also belongs to an American company, which is the part that unsettles European capitals. Maven is still the top choice for the job, Politico reported, and many European governments are uneasy about handing that much power to a US vendor. Arcadia is Paris’s answer. It uses AI to pull battlefield data into a single operational picture, and the French military is already testing it.
France is selling it as a like-for-like swap. French armed forces minister Catherine Vautrin told the French Senate in June that her ministry backs the project fully. She described Arcadia as a sovereign command-and-control system that would meet NATO standards and serve as an interoperable alternative to Maven. The French military has already started pitching the system to allies, Politico reported.
The suppliers are the problem Berlin’s objection is not really about the software. It is about the supply chain behind it. The German assessment notes that the data and technology powering Arcadia come exclusively from French defence companies. It names Mistral AI, Safran.AI, Thales and Airbus.
That list is the whole argument in miniature. Every one of those firms is national champion material. A German general running Arcadia would depend on a French model, French sensor software and French airframes. None of this is hypothetical for the companies involved.
Mistral has spent two years warning European buyers that foreign model providers can switch them off. Airbus made the same case with its own money when it began moving critical applications off Amazon Web Services and onto a French cloud. The pitch works. It just works equally well in reverse, when the buyer sits in Berlin rather than Paris.
Brussels declined to pay for it France also wanted the European Commission to treat Arcadia as a pan-European project. That has not gone to plan either. The German notes record that Brussels had initially earmarked EUR3.3mn in EU grants for the project, and that France then pushed unsuccessfully to keep the money. The Commission concluded that Arcadia did not meet the criteria for a European Defence Project of Common Interest. “The Commission’s assessment and decision were, as expected, criticized in particular by France,” the notes say.
Brussels left the door open for a fresh application once the project matures. The sum is small. The signal is not. A project pitched as Europe’s sovereign answer to an American vendor could not clear Europe’s own bar for a project of common interest.
It also fits a pattern the bloc keeps repeating, in which European content rules cover hardware in detail and barely mention software. A fight with a long precedent Chancellor Friedrich Merz and President Emmanuel Macron agreed in July to explore a European military digital backbone. It would combine satellite, drone, radar and signals intelligence into one operational picture for commanders. Their declaration named Arcadia, then added the phrase now doing the heavy lifting: “as well as comparable German solutions”.
That formulation was diplomacy rather than a decision. The tension underneath it is old. Critics regularly accuse Germany of favouring its own defence industry. Berlin, in turn, reads French appeals to European sovereignty as marketing for French firms.
Earlier this year the fighter-jet pillar of the Franco-German-Spanish Future Combat Air System collapsed, after years of disputes between Dassault Aviation and Airbus Defence and Space. France, meanwhile, has been acting on its own advice. Its intelligence service is already dropping Palantir for a homegrown rival. That is precisely the move Paris now wants its neighbours to copy.
What happens next Arcadia sits on the agenda for talks next week between Merz and defence minister Boris Pistorius, according to a separate note seen by Politico. Germany is building its own system in parallel. The documents call it the Bundeswehr’s data-integration platform, and almost nothing about it has reached the public. The wider scramble across France, Germany, Ukraine and the UK has one shared driver.
European governments are no longer confident about the US commitment to the continent’s security under Donald Trump. The German defence ministry declined to comment to Politico, and the French armed forces ministry did not respond to its request. Three outcomes are still live. Arcadia becomes one component of a broader European system.
Or a French contribution running beside German technology. Or a national platform that merely talks to its neighbours. Europe has answered the easy question, which was whether it wanted to keep depending on an American vendor. The harder one is whether two governments that could not agree on a fighter jet can agree on the software telling their commanders what to shoot at.
