Does China's J-20 rival other stealth fighters?
Center for Strategic and International Studies
The Chengdu J-20 marks the first entry of a multirole stealth fighter into China’s armed forces. According to the Department of Defense (DOD), China views stealth technology as a core component in the transformation of its air force from “a predominantly territorial air force to one capable of conducting both offensive and defensive operations.” Designed for enhanced stealth and maneuverability, the J-20 has the potential to provide China with a variety of previously unavailable air combat options and enhance its capability to project power.
