ZeroAvia and Marshall Aerospace (Mashall) have formed a collaboration to develop hydrogen-electric propulsion and power systems for military aircraft.
The partnership combines ZeroAvia’s flight-tested hydrogen-electric technology with Marshall’s expertise in military aircraft modification, integration and certification. The companies will focus on integrating hydrogen-electric systems into both new and existing defence platforms, supporting applications including uncrewed aerial systems (UAS), intelligence, surveillance and reconnaissance (ISR), logistics, training and special mission aircraft.
The collaboration aims to accelerate the adoption of next-generation propulsion by addressing hydrogen storage, aircraft integration, thermal management, safety, certification and through-life support. The technology is expected to improve endurance, reduce acoustic and thermal signatures, lower operating costs and increase operational flexibility.
“This collaboration is about translating the promise of hydrogen-electric propulsion and power into real operational capability for military users,” said Christine Ourmieres-Widener, Executive Chair of ZeroAvia. “Many military applications require greater endurance, lower thermal signatures and improved operational flexibility than existing electric propulsion technologies can provide today. By combining our validated propulsion technology with Marshall’s deep integration and certification expertise, we can accelerate the pathway to deployment.”
ZeroAvia has already achieved major flight-test and regulatory milestones with the UK Civil Aviation Authority and the US Federal Aviation Administration. The company also holds more than 3,000 pre-orders for its ZA600 and ZA2000 hydrogen-electric propulsion systems from airlines, OEMs and defence customers worldwide.
