Its stable performance validated its design and reliability, reported the Science and Technology Daily on Monday.The maiden flight signifies another significant advancement for China in the field of high-end unmanned aviation equipment.As a large cargo drone developed under China's civil aviation airworthiness procedures, the TP1000 boasts a payload capacity of 1,000 kilograms, a maximum range of 1,000 kilometers when fully loaded, and a 7-cubic-meter cargo bay.With a takeoff weight of 3.3 tonnes, it features twin-engine modular installation, a self-developed multi-redundant flight control system, and advantages in endurance, payload, and cost-efficiency.An aerial drone photo shows China's domestically developed tonne-class unmanned transport aircraft, the TP1000, conducting its maiden flight at an airport in east China's Shandong Province, March 15, 2025.

Currently, the company's fixed-wing TP500 model, with a payload capacity of 500 kilograms, successfully completed test flights of its newly certified design in February 2025, moving into a new certification phase. Meanwhile, the TR100, a core model with a payload capacity of 150 kilograms, has also entered the trial operation stage, according to Jin."Compared to the TP500, which carries 500 kg over 500 km, the TP1000 offers greater payload and range. Together, they will address the booming demand for low-altitude logistics," he said.The company has secured 30 orders from clients including ZTO Express.An aerial drone photo shows staff members celebrating the maiden flight of China's domestically developed tonne-class unmanned transport aircraft, the TP1000, at an airport in east China's Shandong Province, March 15, 2025.
