Future developments we can expect to see in China’s aviation capabilities certainly include a fifthgeneration fighter. Rumors of such a program and even photos of an alleged full-scale mockup have long circulated, and, last year, He Weirong, a PLAAF deputy commander, stated that such an aircraft was scheduled to enter service in the 2017-2019 timeframe. The specific capabilities of this aircraft, however, are unclear. The full-scale mockup photo suggested an aircraft with a reduced radar cross-section, though perhaps not in the class of the U.S. F-22 and F-35.
At the rate at which China’s electronics capabilities are progressing, an active electronically scanned array (AESA) radar and advanced data links for this aircraft seem plausible. Whether it will have the thrust-vectoring and supercruise capabilities of the F-22, however, is less certain.
