Harbin BZK-005 is a Chinese fixed-wing military/ISR drone from Harbin Aircraft Industry, intended for long-duration surveillance-oriented missions rather than consumer or commercial flying. Even with limited public data, its confirmed headline figures are notable: **1,250 kg maximum takeoff weight**, **40 hours endurance**, **180 km/h maximum speed**, and an **8,000 m ceiling**. For researchers, defense journalists, and readers comparing larger unmanned aircraft, that places the BZK-005 in a serious persistence-focused class, though many payload and procurement details remain unconfirmed.
