The J-20 was built with technology and design information stolen from Lockheed F-22 and other low observable a projects and information purchased from Iran’s downing of one of our recon drones
Obama’s refusal to destroy that captured drone was a major gift to Iran and a huge blow to US national security
The J-20 is pretty good from some frontal aspects which make it particularly effective at reaching and attacking an isolated target like an aircraft carrier
In fact, with its large size, it seems optimized to go after American carriers and destroy them
If Wang Wei is the pilot, they might lose it.
