The CXXMUH450 is a 500kg-class coaxial twin-rotor unmanned helicopter specially developed for military and police medium-range logistics missions. It integrates three core technologies: domestic aviation heavy fuel power, adaptive robust flight control, and ship-borne takeoff/landing adaptation. Focusing on the pain points of military and police logistics—"maritime ship-island supply, plateau medium-range transportation, and equipment delivery in complex areas"—it can efficiently perform 150kg-level material transportation, emergency rescue, and equipment transfer tasks in scenarios such as ship decks, plateau outposts, and mountain strongholds. It provides a medium-range solution for military and police "sea-land-plateau" multi-domain logistics support, featuring "balanced load and flexibility, and equal emphasis on safety and efficiency."
