Quantum Systems announced the signing of its $1.2 billion Series D financing round, valuing the company at about $8 billion on a post-money basis. The funding round was co-led by Blackstone, Noteus, Airbus, and Advent. And the round was also backed by a syndicate of crossover and long-term institutional investors, including BOND, Fidelity Management & Research Company, Wellington Management, A.P. Moller Holding, and Elephant Lake Ventures. Existing shareholders Balderton and HV Capital also participated.
Quantum Systems said the financing more than doubled its valuation, reflecting its fast-growing revenue, demonstrated profitability, and market position in multi-domain autonomous systems.
With the funding, Quantum Systems plans to accelerate its shift from individual uncrewed platforms to an interoperable family of systems connected through MOSAIC UXS, its software ecosystem for uncrewed systems. The company also announced that Airbus Defence and Space and Quantum Systems agreed to deepen their strategic collaboration to accelerate the development of next-generation sovereign European defense capabilities.
The proceeds will be used to expand production capacity, strengthen supply chain resilience, scale deliveries across allied markets, and continue investing in software and AI capabilities.
Quantum Systems has already deployed its systems at scale. In Ukraine in 2025, the company’s systems executed more than 19,000 missions. And the company has expanded its production footprint across Germany, Ukraine, the United States, Australia, Romania, the United Kingdom, and the Baltics.
Morgan Stanley & Co. International plc served as exclusive financial adviser and placement agent for the transaction.
KEY QUOTES:
“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.”
Florian Seibel, co-CEO and co-founder of Quantum Systems
“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.”
Sven Kruck, co-CEO of Quantum Systems
“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. 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.”
Jonas Jarosch, CFO of Quantum Systems
“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.”
Michael Schoellhorn, CEO at Airbus Defence and Space
“A structural shift in the European defence market has created significant demand for capital to support the sector’s development and the adoption of advanced technologies. We look forward to supporting the company as it scales operations in Germany, expands across allied markets and builds the infrastructure for durable, long-term growth and security.”
David Kaden, Senior Managing Director at Blackstone
“Quantum Systems reflects the growing strength of Europe’s deep-tech and defence ecosystem. The company has shown how software, AI and operational execution can turn unmanned systems into scalable, sovereign multi-domain capabilities.”
Zoé Fabian-Frey, General Partner at Noteus
“We believe Quantum Systems sits at the centre of the shift towards unmanned systems, with the product depth, customer traction and industrial ambition to scale internationally. This investment reinforces our commitment to next-generation defence technologies and we are looking forward to partnering with the team to expand production and to build for long-term growth.”
Mike Marshall, Managing Director at Advent
