The Tengden TB-001 is a medium-altitude long-endurance (MALE) unmanned combat aerial vehicle (UCAV) designed by Sichuan Tengden. It is used by the People's Liberation Army.

A twin-boom aircraft has two longitudinal auxiliary booms. These may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage.
