An upgraded version of the Chinese Phased Array Radar, as well as the KJ-2000 and KJ-500 airborne early warning and control systems could well cope with the task, People's Daily Online reported, citing military expert Yin Zhuo.
The incident took place on February 10.
Initial reports did not specify the type of the aircraft or the country the plane belonged to, but Yin Zhuo mentioned that if the planes were F-22s then the Chinese could track them.
"In fact – it's very possible that China can track the Raptor. Stealth is not a cloak of invisibility, after all. Stealth technology simply delays detection and tracking," defense expert Dave Majumdar wrote for the National Interest. "Even combat-configured F-22s are not invisible to enemy radar, contrary to popular belief."
