Mitsubishi Heavy Industries (MHI) and Yamaha Motor have successfully completed the first flight test of a medium-sized multirotor drone prototype capable of carrying up to 200 kilograms. This hybrid UAV features Yamaha’s innovative compact power generator designed to greatly extend flight endurance beyond traditional battery-powered models.
The collaboration, launched in March 2024, combines MHI’s advanced aircraft development expertise with Yamaha’s small, high-power engine technology and electric propulsion innovations. The prototype aims for a cruising range of 200 km—vastly improving on the 15 km range typical of single-battery drones.
In mid-April, the drone took off for its maiden flight at MHI’s research center. Its hybrid system generates electrical power from an onboard engine to drive the rotors, delivering both efficiency and endurance. Measuring about 6 meters in length, the drone is also designed for easy transport by truck to various takeoff and landing sites.
The prototype will be showcased at the Japan Drone 2025 exhibition at Makuhari Messe from June 4 to 6.
Looking ahead, these medium-sized drones are poised to transform logistics and rescue missions. They can deliver supplies to remote or disaster-affected areas where traditional vehicles struggle, improve transportation routes to islands and mountainous regions, and support construction and maintenance in rugged terrain inaccessible by land.
