Europe's AI Sovereignty Problem Just Became a Defence Emergency

In March 2025, NATO integrated Palantir's Maven Smart System into its operations. Maven is an AI-powered targeting and intelligence platform built by an American defence contractor. It uses machine learning to process battlefield data and generate targeting recommendations.

For most observers, it was a routine defence procurement decision. For European strategists, it was a wake-up call they can no longer ignore.

The Sovereignty Question

If NATO's targeting systems run on American-built AI, then European battlefield decisions are mediated through American technology companies. That's not inherently a problem — until it is. Until there's a geopolitical tension between US interests and European interests. Until data sovereignty questions become military strategy questions.

The EU has spent years building regulatory frameworks around AI — the AI Act, transparency requirements, bias audits. None of it addresses the core vulnerability: Europe doesn't have a Palantir. It doesn't have a Maven-equivalent. It's not close.

What This Means

European defence contractors have been consolidating and modernising for years. But AI-powered defence systems require a different infrastructure: massive compute capacity, talent pools, data access, and the ability to iterate at speed. The US and China have both. Europe has fragmented national efforts and bureaucratic caution.

The EDIP programme commits €1.5 billion to defence production. It's significant. But it's not close to what you'd need to build a European Maven equivalent. That would require a coordinated, multi-year, multi-billion-euro commitment that Brussels has not yet made.

The Strategic Problem

If Europe's defence AI comes from American vendors, Europe's military autonomy is contingent. It's contingent on American companies, American data policies, American geopolitical interests.

That may not matter if the US and EU always align. But Europe learned in 2016-2020 that assuming alignment with Washington is dangerous.

The Maven acquisition shows what European AI autonomy actually costs. The question is whether Europe is willing to pay it.
