Recently, the Ukrainian Armed Forces have, for the first time ever, utilized hydrogen-fuel-powered hybrid drones on the front lines. This marks the inaugural practical use of hydrogen-powered drones in combat scenarios worldwide. Produced by the Ukrainian firm Skyeton, this drone is an enhanced iteration of the pre-existing Raybird model and has already successfully executed comprehensive combat missions at the front.

According to Skyeton, the modified Raybird drone boasts an internal layout that has been redesigned to accommodate hydrogen fuel tanks. Its structural configuration and center of gravity have been fine-tuned to accommodate the placement of avionics gear and mission-specific payloads. The drone incorporates a hybrid power system that merges hydrogen fuel cells with electric propulsion. In this setup, the hydrogen fuel cells generate electricity, which is then used by the electric motors to provide thrust.

The drone has a maximum takeoff weight of roughly 23 kilograms, a wingspan measuring approximately 4.7 meters, and can carry a maximum mission payload of up to 10 kilograms. It is capable of cruising at a speed of about 110 kilometers per hour and boasts an endurance of up to 12 hours. When compared to traditional internal combustion engine power systems, the hybrid-powered Raybird excels in noise reduction and infrared signature management. Its engine operates with greater stealth and emits a minimal thermal signature, thereby diminishing the likelihood of detection in frontline settings.

Presently, the drone's main role is to conduct medium- to long-range reconnaissance operations. It is outfitted with radar and an array of other sensors, enabling it to perform long-distance target detection and in-depth reconnaissance missions.
