Quantum Systems has signed a $1.2 billion Series D financing round to expand its development and production of autonomous unmanned systems for air, land, sea and adjacent domains. The Munich-based company said the round values it at about $8 billion on a post-money basis. The financing was co-led by Blackstone, Noteus, Airbus and Advent, with participation from BOND, Fidelity Management & Research Company, Wellington Management, A.P. Moller Holding and Elephant Lake Ventures, as well as existing shareholders Balderton and HV Capital.
Quantum Systems plans to use the proceeds to increase production capacity, strengthen its supply chain and scale delivery across allied markets. The company also intends to continue investing in software and artificial intelligence capabilities that support interoperable unmanned operations.
A central focus of the financing is the company’s transition from individual uncrewed platforms to an integrated family of systems connected through MOSAIC UXS, its software ecosystem for unmanned systems. The platform is designed to link unmanned vehicles, sensors, counter-UXS systems, drone ports and partner technologies into a single interoperable operating environment.
Quantum Systems develops unmanned systems intended for use across air, land, sea and adjacent domains. The company serves defence, security and civil resilience customers in Europe, NATO and allied markets.
Airbus Defence and Space and Quantum Systems also agreed to deepen their strategic collaboration. The companies said the expanded cooperation will combine expertise in autonomous systems, software and artificial intelligence to support European defence capabilities.
“The future is unmanned. Defence will be defined by autonomous systems that can operate together across domains in real time,” said Florian Seibel, co-CEO and co-founder of Quantum Systems. “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.”
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.”
David Kaden, Senior Managing Director at Blackstone, said: “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.”
Zoé Fabian-Frey, General Partner at Noteus, added: “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.”
Mike Marshall, Managing Director at Advent, said: “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.”
