Quantum Systems is a Munich-based maker of autonomous reconnaissance drones whose Vector drone has flown more than 19,000 missions in Ukraine. In July 2026 it closed a $1.2 billion Series D at a roughly $8 billion valuation — the largest private defence-tech round in European history — co-led by Blackstone, Airbus, Advent and Noteus, more than doubling its late-2025 valuation. Airbus Defence and Space simultaneously deepened a strategic partnership, a model pairing a defence prime with the startup it might otherwise have tried to outcompete.
