China flies world‑first 7.5‑ton hydrogen‑powered unmanned cargo aircraft
China completed a world‑first flight of a 7.5‑metric‑ton (16,535 lb) unmanned cargo aircraft in Zhuzhou, Hunan, powered by a megawatt‑class (~1 MW) hydrogen turboprop. AECC said the test demonstrates hydrogen propulsion feasibility for light cargo UAS and begins a domestic technology chain for sustainable aviation.
