Tengden TB-001
Chinese MALE UCAV with twin-boom design and 35-hour endurance.
The People's Liberation Army operates the Tengden TB-001, a medium-altitude long-endurance unmanned combat aerial vehicle built by Sichuan Tengden. Its design features a straight high-mounted wing, a twin-boom layout, and two turbocharged-piston engines, each turning a three-bladed propeller mounted on either side of the central fuselage.
The base variant was first shown in September 2017. A three-engined version, the TB-001A, appeared in 2020 after reportedly less than six months of development. This upgraded model adds an engine on the tail, boosting maximum takeoff weight from 2,800 kilograms to 3,200 kilograms, payload from 1,200 kilograms to 1,500 kilograms, and service ceiling from 8,000 metres to 9,500 metres (with a sustained ceiling of 9,000 metres). Takeoff distance shortens to 500 metres, and the maximum rate of climb exceeds 10 metres per second. Flight endurance remains 35 hours.
In August 2021, the TB-001 was spotted twice by the Japan Maritime Self-Defense Force over the East China Sea. On the first occasion it flew alone; on the second, it transited the Miyako Strait alongside two Shaanxi Y-9 aircraft.
The TB-001 carries no crew. It has a length of 10 metres, a wingspan of 20 metres, and a height of 3.3 metres. Maximum range is 6,000 kilometres, with 35 hours of endurance carrying a 1,000-kilogram payload. Four hardpoints can mount 250-kilogram laser-guided bombs, FT-7 glide bombs, FT-9 guided bombs, AR-4 air-to-surface missiles, AR-3 cruise missiles, and FT-8D or FT-10 air-to-ground missiles. Line-of-sight communication with a ground command post reaches 280 kilometres; satellite data links extend that to 3,000 kilometres.

Lore & Background
The TB-001 was first unveiled in September 2017. In 2020, a three-engined variant was unveiled, reportedly taking less than six months to develop. The aircraft uses a twin-boom design with a pair of turbocharged-piston engines, each driving a three-bladed propeller on either side of the central fuselage, underneath a straight high-mounted wing.
In August 2021, the TB-001 was twice spotted in the East China Sea by the Japan Maritime Self-Defense Force. In the first encounter, it flew over the East China Sea unaccompanied; in the second, it flew through the Miyako Strait alongside two Shaanxi Y-9 aircraft. The TB-001A variant upgrades the original with an additional engine on the tail, increasing maximum takeoff weight from 2,800 kg to 3,200 kg, payload from 1,200 kg to 1,500 kg, and flight ceiling from 8,000 m to 9,500 m, while shortening takeoff distance to 500 m and achieving a maximum rate of climb over 10 m/s. Endurance remains 35 hours.
Reader's Guide
The Tengden TB-001 represents a significant Chinese MALE UCAV development, first unveiled in September 2017 and operated by the People's Liberation Army. Its twin-boom design and twin turbocharged-piston engines provide a 35-hour endurance with a 1,000 kg payload, and a range of 6,000 km. The rapid development of a three-engined variant in under six months, unveiled in 2020, highlights iterative design capability. The TB-001A variant further enhances performance with increased takeoff weight, payload, and ceiling, while maintaining the same endurance. Operational use was demonstrated in August 2021 when the TB-001 was twice observed by Japanese forces in the East China Sea, including a flight through the Miyako Strait with two Shaanxi Y-9 aircraft. The aircraft carries up to four hardpoints for various guided bombs and missiles, and communicates via line-of-sight ground command up to 280 km or satellite data links up to 3,000 km. Its specifications and variants position it as a versatile platform within China's unmanned aerial vehicle inventory.
