It reaches a maximum take-off weight of 7 tonnes. The drone itself weighs 3.5 tonnes and can carry an equal load.Its airframe stretches 17 meters long with a wingspan of 25 meters. Engineers designed a fully enclosed cargo bay with a volume of 18 cubic meters.The aircraft includes both front and rear access doors, allowing faster turnaround during loading and unloading operations.CCTV described the platform as an “unmanned aerial heavy truck.” The drone relies on twin turboprop engines and supports short take-off and landing operations.This design allows it to operate on basic runways with limited infrastructure.“This cargo drone is highly adaptable to its environment, uses twin turboprop engines, and has the ability to take off and land on simple runways in high-altitude areas, as well as perform short take-offs and landings,” said Cai Hangqing, chairman of Beijing Northern Changying UAV Technology, as reported by SCMP.Developers built the CY-8 to support both civilian and military roles. The drone can switch payload configurations quickly, making it suitable for a wide range of missions.CCTV reported that operators can deploy it for emergency communications, weather modification, and electronic reconnaissance.It can also support logistics, disaster relief, and supply delivery in difficult terrain.The drone’s design focuses heavily on high-altitude performance.It can operate in regions such as the Tibetan Plateau, where elevations range between 4,000 and 5,000 meters.Engineers also optimized it for island operations, enabling use on short and simple airstrips.The CY-8 requires less than 500 meters for take-off and landing.It also offers a range of more than 1,850 miles, extending its operational reach across remote or strategically sensitive areas.<h2 id="h-expanding-global-competition">Expanding global competition</h2>China’s latest drone arrives as competition intensifies in the heavy cargo UAV segment.Beijing continues to invest in uncrewed systems capable of operating in extreme environments.Other Chinese projects are already in progress. Air White Whale is developing the W5000, a larger 10-tonne-class cargo drone.A scaled prototype recently completed its maiden flight.China has also tested a heavy-lift unmanned helicopter, the Boying T1400. That platform targets operations from mountainous regions to maritime zones.The United States is advancing similar systems.California-based Sabrewing developed the RH-1-A Rhaegal cargo drone, which completed its first hover flight in 2022.A larger variant is expected to reach a maximum take-off weight of 6.25 tonnes.Unlike the CY-8, Sabrewing’s design uses vertical take-off and landing. This removes the need for runways and enables operations in confined spaces.The company has already secured collaborative orders from the US Air Force.China plans to continue flight testing of the CY-8. The developer aims to move toward full-scale production before the end of the year.</div></div>

中国成功测试了世界上最重的货运无人机——长鹰-8（CY-8），其最大起飞重量为 7 吨，航程可达 1850 英里。CY-8 旨在用于民用和军用，能够在高海拔和偏远地区操作，起降所需距离不足 500 米。其特点包括全封闭货舱和双涡轮螺旋桨发动机，允许短距离起降。此项发展是在重型货运无人机市场全球竞争日益加剧的背景下进行的，中国计划进一步进行飞行测试，并力争在年底前实现大规模生产
