France and Germany have taken a significant step toward technological sovereignty in defense by pledging to develop a European alternative to Palantir's military AI software. The announcement came from a joint declaration signed after talks between French President Emmanuel Macron and German Chancellor-in-waiting Friedrich Merz, underscoring a shared determination to reduce reliance on American defense technology amid growing transatlantic tensions.
A Sovereign Digital Backbone
The declaration commits both nations to examine what it calls a "European sovereign digital backbone" that would cover data-centric security, artificial intelligence, and cloud solutions. At the heart of this initiative is France's Arcadia, an AI-powered command-and-control platform designed to process battlefield data and intelligence in real time. Arcadia, developed by the French defense procurement agency DGA and industrial partners, will serve as the starting point for the joint project, alongside unspecified "comparable German solutions." The goal is to create a system that can handle sensitive military data without exposure to foreign jurisdiction—specifically, to the United States, where Palantir is headquartered.
This move is not entirely unexpected. Both France and Germany have already taken concrete steps to remove Palantir from their intelligence services. In June, France's General Directorate for Internal Security (DGSI) announced it was replacing Palantir's software with ArgonOS, a platform developed by the French company ChapsVision. This decision came just six months after renewing Palantir's contract, signaling a rapid shift in strategy. Germany's Federal Office for the Protection of the Constitution (BfV) followed suit, also choosing ChapsVision for the same role. Furthermore, the German armed forces (Bundeswehr) have excluded Palantir from its defense cloud procurement entirely, effectively shutting the American firm out of one of Europe's largest military IT modernization projects.
Why Sovereignty Matters
The rationale behind these moves is not about technology performance—Palantir's systems are widely acknowledged as highly effective. As a top NATO commander recently told Politico, there is "no real European alternative" to Palantir's Maven software, which the alliance uses for battlefield data processing and analysis. The issue is one of strategic autonomy. With transatlantic relations becoming increasingly unpredictable—especially given potential shifts in U.S. foreign policy—European nations are questioning the wisdom of entrusting their most sensitive military infrastructure to an American company. Palantir, founded by Peter Thiel and Alex Karp, has deep ties to U.S. intelligence and defense agencies, and its software operates under U.S. law, which can compel data sharing with the American government. For France and Germany, this raises unacceptable risks in an era where Europe must be able to defend itself independently.
Alex Karp, Palantir's CEO, has dismissed such concerns. In an interview with German newspaper Bild last month, he called Germany's refusal to consider his company "conversations about witchcraft," arguing that Palantir's software is "proven on every serious battlefield." Karp's argument that functionality should trump sovereignty has not moved Berlin or Paris. The joint declaration makes clear that Europe's ability to protect its own secrets and operate autonomously is paramount.
Beyond AI: Missiles, Tanks, and Combat Standards
The joint declaration extends well beyond AI software. It also includes commitments to cooperate on long-range weapons, tanks, and a new European combat standard for aircraft. On missiles, France, Germany, and the United Kingdom will examine collaboration on systems with a range of up to 2,500 kilometers, drawing on the capabilities of ArianeGroup, a joint venture between Airbus and Safran that already produces Europe's heavy-lift rocket family. This signals a desire to develop a deep-strike capability independent of American or British-only systems, particularly important as European nations seek to bolster deterrence against Russia.
On land systems, the Franco-German Main Ground Combat System (MGCS) tank program—intended to replace Germany's Leopard 2 and France's Leclerc tanks—will launch a research program focusing on autonomous driving, advanced sensors, and battlefield networking. The MGCS has been troubled by industrial disagreements between the main contractors (KNDS on the French side and Rheinmetall on the German side), but the new commitment aims to accelerate the project. Autonomous driving is seen as critical for future armored warfare, allowing tanks to operate in swarms with reduced crew sizes while maintaining lethality.
The Absence of FCAS and the Rise of a Combat Standard
Notably absent from the declaration was the troubled Future Combat Air System (FCAS), a next-generation fighter jet program that has been plagued by disagreements between Airbus (leading the German effort) and Dassault Aviation (leading the French side). Instead, France and Germany agreed to create a "European collaborative combat standard" that would allow fighter jets and drones from different nations to communicate and share data on the battlefield. This pragmatic approach sidesteps the immediate impasse over FCAS while still building toward interoperability. The idea is that even if France and Germany develop separate platforms (or together with other partners), they will be able to operate as part of a cohesive network, sharing sensor data and coordinating strikes in real time.
Historical Context and Strategic Implications
This push for European defense technology sovereignty is not new. The idea of a "European digital backbone" has been discussed in Brussels for years, often framed as part of the EU's broader quest for strategic autonomy. However, actual progress has been slow, hampered by national rivalries, differing threat perceptions, and industrial competition. The Ukraine war, which exposed Europe's dependence on American intelligence and satellite communications, has accelerated the timeline. France and Germany, as the EU's two largest economies, are now taking the lead—though critics note that Germany's defense procurement remains deeply cautious and often slow.
If successful, the European alternative to Palantir could have far-reaching implications for the global defense AI market. Palantir has enjoyed a near-monopoly in providing data analytics software to Western intelligence agencies, with clients including the CIA, FBI, U.S. Special Operations Command, and numerous NATO allies. A credible European rival would not only reduce dependence but also create a more competitive landscape, potentially driving down costs and pushing innovation. However, the challenges are immense. Building a platform that can match Palantir's capabilities—specifically its Gotham and Foundry systems, which integrate massive datasets and apply machine learning for predictive analysis—requires years of development, significant investment, and close collaboration between military forces, intelligence agencies, and technology companies.
France's Arcadia is already operational in prototype form and has been tested by the French Army in exercises. It focuses on providing situational awareness and decision support to commanders, integrating data from sensors, satellites, and human intelligence. However, scaling it up to the level required by France and Germany together—and potentially other EU nations—will require standardization of data formats, security protocols, and legal frameworks. The "comparable German solutions" mentioned in the declaration remain vague; Germany has not publicly identified a direct counterpart to Arcadia, though firms like Hensoldt and Rohde & Schwarz have capabilities in defense IT.
Another obstacle is the European defense industry's fragmentation. Unlike the United States, where a few large primes dominate, Europe has dozens of national champions that often compete rather than cooperate. The FCAS difficulties illustrate how national pride and commercial interests can stall even joint programs. The new combat standard for aircraft is an attempt to bypass such disputes by focusing on interoperability rather than a single platform. A similar approach will be needed for the AI backbone: rather than building one monolithic system, France and Germany may end up with a federation of secure clouds and data lakes that can communicate with each other, akin to the architecture used by NATO's Allied Command Transformation.
For Palantir, the European push is a serious threat to its future growth. The company has been aggressively expanding its defense business in Europe, with contracts in the UK, Poland, and Romania, among others. Losing France and Germany—two of the continent's biggest defense spenders—is a major setback. Karp's public outburst indicates he understands the stakes. However, Palantir still has allies within European militaries who value the proven performance of its software. The battle over Europe's digital defense is far from over.
Ultimately, the success of the Franco-German initiative will depend on political will, industrial execution, and the willingness of other EU nations to join. The declaration sets a clear direction: Europe intends to build its own capabilities rather than rely on a single American supplier. Whether it can turn that intention into operational software that soldiers trust remains the harder part. But by putting this commitment in a joint declaration, France and Germany have signaled that the era of automatic dependence on U.S. defense tech is ending. The race to build Europe's Palantir has begun.
