Israeli defense firm Elbit Systems is equipping its UAV portfolio with a next-generation hybrid propulsion solution, claiming the system represents the first true hybrid drone propulsion technology of its kind. The move follows a long-term partnership with Lowental Hybrid, whose Native Parallel Hybrid system combines combustion and electric power in a single, integrated architecture.
Unlike conventional hybrid approaches, the propulsion system enables smooth switching between power modes during flight, without the need for extensive structural modifications. The companies say the technology can dramatically increase flight endurance—by as much as fivefold—while maintaining low-noise performance, a key advantage for sensitive ISR and long-duration surveillance missions.
Lowental has emphasized that the propulsion system is NATO-compliant and adaptable to multiple UAV classes. Elbit confirmed that early flight testing validated interoperability and performance, supporting the system’s readiness for operational deployment across different unmanned platforms.
The agreement begins with a $1.4 million initial investment from Elbit and includes options for incremental capability upgrades over time. Expected to run for more than ten years, the partnership will see Lowental provide continuous engineering and technical support. Elbit officials described the program as a clear demonstration of how collaboration between innovative startups and major defense contractors can deliver transformative advances in UAV propulsion and mission effectiveness.
