Skyeton is unveiling an updated version of its Raybird UAV, now powered by a hydrogen fuel cell-driven electric motor for extended, stealthier flight.
The new propulsion system allows the drone to remain in the air for about 12 hours, with developers targeting up to 20 hours in future iterations.
With minimal heat output, high-altitude capability, and near-silent operation, the Raybird is designed to reduce detectability during missions.
