The German powerhouse for unmanned systems, Quantum Systems, has today announced the signing of its €1 billion ($1.2 billion) Series D financing round, more than doubling the company’s valuation at around €7 billion ($8 billion) on a post-money basis.
The round was co-led by Blackstone, Noteus, Airbus and Advent, and supported by 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.
Florian Seibel, co-CEO and co-founder of Quantum Systems, says: “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 $1.2 billion of dry powder to execute.”
Quantum Systems’ Series D follows a period of sustained activity of European drone, autonomy and DefenceTech financing.
In 2026, EU-Startups has reported at least €68 million in comparable or adjacent rounds across unmanned-systems software, UAV guidance, counter-UAS, aerial intelligence, maritime autonomy and drone-enabled inspection, including Six Robotics, Kelluu, AirHub, Occam Industries, PDKINEMATICS, Donecle and ABZ Innovation.
Quantum Systems has also been covered previously by EU-Startups, including a €160 million Series C in May 2025, a €180 million Series C extension in November 2025, and a €150 million financing package in February 2026.
Taken together with the new Series D, the disclosed funding referenced here amounts to approximately €1.07 billion, placing the German company’s latest round well above the other 2026 European activity reported in adjacent unmanned, drone and defence autonomy segments.
Sven Kruck, co-CEO of Quantum Systems, adds: “In just a few years, Quantum Systems has become a trusted defence technology partner. This financing allows us to scale production, expand globally, and deliver the next generation of AI-powered autonomous systems across air, land, sea and adjacent domains.”
Founded in 2015, Quantum Systems is a leading European DeepTech defence prime. The company develops, produces and deploys interoperable unmanned systems that combine battle-proven and modular hardware, software and AI to deliver mission-critical capabilities across air, land, sea and adjacent domains.
Through MOSAIC UXS, its software backbone for unmanned operations, Quantum Systems connects platforms, sensors, counter-UXS systems, drone ports and partner technologies into one interoperable system.
With today’s 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.
Proceeds will also be used to expand production capacity, strengthen supply chain resilience, scale delivery across allied markets and continue investing in software and AI capabilities.
“Quantum Systems has built a financial profile that sets a new benchmark for the defence market: triple-digit growth, double-digit profitability and disciplined execution at scale,” says Jonas Jarosch, CFO of Quantum Systems. “This financing unlocks our next phase of growth as we industrialise our multi-domain platform, scale production across allied markets and continue investing in the technology infrastructure that defines our long-term competitive position.”
Quantum Systems says they are entering 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.
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.
Michael Schoellhorn, CEO at Airbus Defence and Space, says: “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.”
