TB-001 Scorpion

A Chinese twin-boom MALE unmanned combat aircraft used for long-endurance ISR, maritime surveillance and strike carriage, best known for PLA pressure flights around Taiwan and Japan's southwestern approaches.

Overview

The TB-001 Scorpion, also known as the Twin-Tailed Scorpion, is a Chinese medium-altitude long-endurance unmanned combat aerial vehicle developed by Sichuan Tengden Technology Innovation Co., Ltd. It occupies a distinct niche in China's UAV ecosystem: unlike AVIC's Wing Loong family or CASC's CH-series drones, the TB-001 comes from a smaller Chengdu-based firm that the China Aerospace Studies Institute describes as privately owned but state-sponsored, with PLA-facing customers and "Little Giant" industrial-policy status through CASI.

The aircraft is visually unusual for its twin-boom tail and twin-engine layout, with a later three-engine derivative adding a pusher engine to improve payload, ceiling and short-field performance. In PLA service it has become a visible pressure and surveillance platform, particularly around Taiwan's air-defense identification zone and the Miyako Strait, while export activity has centered on Saudi Arabia and Morocco.

Development

Sichuan Tengden unveiled the TB-001 in September 2017, and GlobalSecurity.org dates the type's first flight to 26 September 2017. The company, also rendered in English as Tengdun or Tengoen, is based in Chengdu and traces its technical lineage to the Chengdu 611 Research Institute ecosystem, according to GlobalSecurity's corporate profile.

The baseline aircraft entered public view as a twin-engine, twin-boom MALE UAV before Tengden introduced a three-engine derivative in 2020. Wikipedia's TB-001 summary, drawing on open reporting, describes the later TB-001A as adding a rear pusher engine and increasing take-off weight, payload and operating ceiling compared with the baseline. Sources differ on exact figures: GlobalSecurity lists the three-engine model at 3,600 kg maximum take-off weight and 40 hours endurance, while other open summaries cite ~3,200 kg MTOW and roughly similar endurance to the original aircraft.

Tengden has also pursued civil and cargo derivatives using the same broad twin-boom family. A four-engine Scorpion D cargo drone, covered by The War Zone, first flew in 2022, but that aircraft is a cargo derivative rather than the armed TB-001 UCAV.
