China’s J-20 stealth fighter jet conducted flight training over Zhuhai on the 25th. The J-20 was performing small radius turns and climbing with added force, according to China’s CCTV military report.
In addition to the installation of the Chinese-made WS-10C engines, the shape of the J-20’s abdominal-mounted Luneburg lens for radar tracking has also changed, with a reduced size compared to previous ones, and it is suspected to be retractable, which means that the aircraft can switch freely between stealth and non-stealth modes.
