The $1.2 billion transaction co-led by Blackstone, Noteus, Airbus and Advent supports Quantum Systems’ industrial scale-up as a leading deep-tech prime for interoperable, multi-domain autonomous capabilities in Europe.

Quantum Systems today announced the signing of its $1.2 billion Series D financing round, valuing the company at  ~ $8 billion on a post-money basis. The round was co-led by Blackstone, Noteus, Airbus and Advent, and supported by a high-calibre syndicate of crossover and long-term institutional investors including BOND, Fidelity Management & Research Company, Wellington Management, A.P. Moller Holding, and Elephant Lake Ventures, as well as existing shareholders such as Balderton and HV Capital. The financing more than doubled Quantum Systems’ valuation, reflecting the company’s fast-growing revenue, demonstrated profitability, and category-defining market positioning with its multi-domain strategy.

With the Series D, Quantum Systems will accelerate the transition from individual uncrewed platforms to an interoperable family of systems connected through MOSAIC UXS, the company’s software ecosystem for uncrewed systems.

Alongside the Series D, Airbus Defence and Space and Quantum Systems agreed to deepen their strategic collaboration, bringing together complementary expertise to accelerate the development of next-generation sovereign European defence capabilities.

Florian Seibel, co-CEO and co-founder of Quantum Systems, said: “The future is unmanned. Defence will be defined by autonomous systems that can operate together across domains in real time. With Quantum Systems, we are building a next generation neo prime that has the potential to disrupt defence as we know it today. We are profitable, deployed around the world and with the latest financing round we now have more than $1.2Bn of dry powder to execute.”

Quantum Systems enters this next phase with proven operational deployment at scale. In Ukraine in 2025, the company’s systems executed over 19,000 missions. At the same time, Quantum Systems has expanded its production footprint across Germany, Ukraine, the United States, Australia, Romania, the United Kingdom and the Baltics.

Michael Schoellhorn, CEO at Airbus Defence and Space, said: “Modern combat is won through decision speed – the ability to capture, process and fuse massive data from air, ground and space faster than the adversary. Autonomous systems are critical, rapidly evolving force multipliers. Their full operational value comes when they are deployed with human oversight, trusted command-and-control structures and seamless integration across crewed and uncrewed assets at the tactical edge. This is why we are excited to deepen our cooperation with Quantum Systems: We are combining crucial architectural, software and AI competencies, thereby accelerating the sensor-to-shooter chain across our joint portfolios. This is where Airbus’ role as a large defence prime is evolving into that of an architect and ecosystem builder.”
