German defence-tech startup Quantum Systems announces a $1.2 billion funding round that more than doubles its valuation to about $8 billion. The company says the round, a Series D, is among the largest fundraising efforts for a European defence startup. Multiple investors participate, with Blackstone, Noteus, Airbus, and Advent named as co-leads.

Quantum Systems produces autonomous drones, positioning itself within a broader push for unmanned aerial vehicles in Europe. Both outlets link the company’s increased valuation and investor interest to a wider rise in military spending across the region, which is boosting demand and funding for defence technology. Bloomberg further frames the move as part of a sector trend that includes other German drone-focused startups benefiting from Europe’s defence spending ambitions.

Quantum Systems’ announcements are presented as a sign of growth plans for its drone business, alongside expectations of sector consolidation. The company’s management discusses expansion potential and how the firm could scale within Europe’s changing defence landscape.
