Another year, another stealthy aircraft

摘要

In September 2012, China's aerospace ambitions were again confirmed when images emerged of a twin-engine medium fighter manufactured by the Shenyang Aerospace Company, unofficially identified as either the J-21 or J-31. Unlike the Chengdu J-20 heavy fighter, unveiled in January 2011 and gauged by some analysts as of possibly Russian heritage, the J-21 reflects US designs, with echoes of the F-22 and the F-35. This has led to speculation of industrial espionage during its development.
