Quantum Systems, a German maker of autonomous reconnaissance drones and battlefield software, raised $1.2 billion in a Series D round on July 2, 2026, at a valuation of about $8 billion. It was reported as the largest private defense-technology financing in European history, and it more than doubled the Munich company's valuation.
Who is backing it
The round was co-led by Blackstone, Airbus Defence and Space and Advent International. Also taking part were crossover and institutional investors that rarely appear in defense-tech rounds — BOND, Fidelity Management & Research, Wellington Management, A.P. Moller Holding and Elephant Lake Ventures — alongside returning shareholders Balderton Capital and HV Capital. Notably, Airbus, a defense prime of the kind the startup says it aims to disrupt, helped lead the deal.
What it builds
Quantum Systems built its reputation on electric vertical-takeoff reconnaissance aircraft, the Trinity Pro and the Vector. The Vector has been heavily used by Ukrainian forces, flying more than 19,000 missions in Ukraine in 2025, giving the company a rare record of battlefield-tested hardware.
The autonomy layer
Increasingly the company's value sits in software. Its MOSAIC platform is a command-and-control ecosystem for coordinating uncrewed systems, and it is explicitly designed to be ITAR-free — free of US export-control restrictions — a selling point for European governments that want sovereignty over the software running their defenses.
A defense-tech funding wave
The raise is among the largest venture rounds Europe has ever produced, and it reflects a broader surge of capital into AI-enabled defense as governments rearm. That investors including a traditional prime like Airbus chose to buy in — rather than compete — underscores how quickly autonomous systems have moved to the center of military procurement.
