Second radar cross-section test range identified in China

- Airbus Defence and Space imagery captured in 2016 shows a new radar cross-section test range in China
- A J-20 full-scale test article is present at the new test range, with apparent design changes suggesting either a new powerplant installation or a new aircraft variant under evaluation
The location near Dingxin AB is well suited for a signature evaluation complex, with flat terrain and a lack of man-made or natural obstructions near the facility. Additionally, the configuration of the J-20 full-scale RCS test article present suggests design changes may be forthcoming to China's fifth-generation stealth fighter.
Along with the Gaobeidian RCS complex, the Dingxin RCS complex illustrates China's increasing attention to low-RCS aircraft design. The Dingxin RCS complex was constructed after the Gaobeidian site, which was built in the 2009 timeframe - perhaps in an effort to establish an RCS test range in a more secure location.
