Designed for both civilian and military applications, the CY-8 can operate in high-altitude and remote areas, requiring less than 500 meters for take-off and landing. Its features include a fully enclosed cargo bay and twin turboprop engines, allowing for short take-offs and landings. This development comes amid increasing global competition in the heavy cargo UAV market, with China planning further flight tests and aiming for full-scale production by year-end." datetime: "2026-04-02T03:02:24.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/281457003.md) - [en](https://longbridge.com/en/news/281457003.md) - [zh-HK](https://longbridge.com/zh-HK/news/281457003.md) --- > Supported Languages: [简体中文](https://longbridge.com/zh-CN/news/281457003.md) | [繁體中文](https://longbridge.com/zh-HK/news/281457003.md) # China Tests World's Heaviest 7-Ton Cargo Drone With 1,850-Mile Range For Recon Ops _Authored by Aamir Khollam via Interesting Engineering,_ **China has pushed further into heavy unmanned aviation with the first flight of the Changying-8 (CY-8),** which it claims is the world’s heaviest cargo drone. _China's Changying-8 (CY-8) cargo drone._ The aircraft combines high payload capacity with short-runway performance, targeting logistics operations across remote, high-altitude, and island regions. **The newly tested Changying-8 (CY-8) blends high payload capacity with short runway performance, signaling a push toward flexible, all-terrain aerial supply systems.** The aircraft completed its first test flight on Tuesday in Zhengzhou, located in central China’s Henan province. It lifted off after a short ground run of 280 meters and stayed airborne for about 30 minutes. According to state broadcaster _CCTV_, engineers used the flight to verify key onboard systems, including avionics, propulsion, and intelligent flight controls. ## Built for heavy payloads The CY-8 stands out for its size and carrying capability. 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. ## Expanding global competition 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. ## Related News & Research - [Why Is Silver Down 4% Today, 4/2/26?](https://longbridge.com/en/news/281547191.md) - [$100 Invested In ProShares Ultra Silver 10 Years Ago Would Be Worth This Much Today](https://longbridge.com/en/news/281548227.md) - [Iridium Communications Stock (IRDM) Moonshots 12% on SpaceX IPO Filing and Amazon Takeover Rumors](https://longbridge.com/en/news/281548482.md) - [Trump speech unleashes more pain on US consumers with $5 gasoline, record diesel in sight](https://longbridge.com/en/news/281550771.md) - [Micron Sell-off Is a "Buying Opportunity" Says Mizuho](https://longbridge.com/en/news/281560003.md)
