German drone maker Quantum Systems raises $1.2 billion for combat autonomy

German company Quantum Systems, a maker of AI-powered autonomous drones and combat systems, has raised $1.2 billion in a Series D funding round. The round valued the Munich-based company at roughly $8 billion, up from $3.5 billion in its previous round in November 2025. It ranks among the largest deals in Europe's defense tech sector this year.

Scale of the round

The round was jointly led by Blackstone, Noteus, aerospace group Airbus and Advent, with participation from Bond, Fidelity Management and Research Company, Balderton Capital and HV Capital, among others. Airbus's involvement is notable because, according to Quantum Systems' founders, large weapons manufacturers like it are exactly the kind of companies the new wave of autonomous systems could partly replace in the future.

From farms to the battlefield

Quantum Systems was founded in 2015 by aerospace engineers Florian Seibel, Armin Busse and Tobias Kloss, initially building drones for agricultural mapping and infrastructure inspection. Russia's 2022 invasion of Ukraine shifted the company's focus toward military applications. The company is already profitable, with production now running in Germany, Ukraine, the United States, Australia, Romania, the United Kingdom and the Baltic states.

Autonomy as the product

The company is developing air, land and sea systems designed to work together in real time without constant human oversight. In 2025, Quantum Systems' platforms flew more than 19,000 missions in Ukraine, which the company presents as proof the technology has matured under real combat conditions.

The future of defense will be defined by autonomous systems capable of coordinating across different domains in real time. - Florian Seibel, co-founder and CEO of Quantum Systems

Europe's defense tech boom

The deal is part of a surge in investment in European defense startups. In 2026 alone they have already attracted $17.4 billion, more than the $11.2 billion raised in all of 2025. Rivals such as US-based Anduril and Shield AI, as well as Germany's Helsing, are also closing multibillion-dollar rounds this year, underscoring how strongly investors are now betting on autonomous military systems over traditional hardware.

The funding will be used to expand production capacity, strengthen the supply chain, speed up deliveries to allied countries and further invest in the software and AI that control the systems. The company also plans further international expansion beyond its current markets.

For Poland, which borders Ukraine and is sharply increasing its defense spending, the growth of companies like Quantum Systems carries direct relevance. European governments are increasingly looking for autonomous systems suppliers outside the United States, and the German company, backed by Airbus and Blackstone, fits into the continent's push for greater technological sovereignty in defense.
