European AI Defence Sovereignty
From foundation models to autonomous defence systems
European AI defence sovereignty is no longer a question of whether Europe can produce competitive foundation models. It is a question of whether Europe can connect compute, sovereign cloud, models, classified data, defence adaptation, sensors, platforms, procurement and operational governance into a coherent industrial chain. The emergence of Mistral AI, Aleph Alpha, LightOn, Helsing, Safran.AI, ICEYE, Quantum Systems, Tekever and other actors shows that Europe now has credible capabilities across several layers of the AI-defence ecosystem. Yet those capabilities remain unevenly integrated. The core problem is therefore not technological absence, but the still-fragmented conversion of European AI, defence software, ISR, autonomy and procurement capacity into an operational model-to-weapon stack.
The report is structured as a six-layer mapping of the European AI defence supply chain. It begins with sovereign compute and cloud infrastructure, then examines the European foundation-model layer through Mistral, Aleph Alpha, LightOn and related actors. It then moves to defence adaptation and operational AI, with particular attention to Helsing, Safran.AI and mission-software integration. The following sections analyse sensor, satellite, ISR and autonomous-platform integration, the relationship between incumbent primes and defence-tech neo-primes, and the emerging governance framework around the AI Act, NATO responsible-AI principles, military certification and human control. The final sections assess capital flows, EU and NATO funding instruments, the US benchmark, and the strategic question of whether Europe is building a sovereign AI defence stack or a fragmented ecosystem of national and private champions.
