There is something about the J20 which ‘states’ practicality and capability more that might be credited.
Form follows function; long range intercepter, stealth as required for weapons system range. Many internal weapons, adding considerable range and opportunity.
Radar unknown, but consider recent Chinese developments of anti-stealth quantum radar; it’s coming perhaps not yet.
So a capable aircraft, development potential, range, manoeuvrability; single crew suggests integrated systems, autonomous operations.
In its own way it looks right.
Take note
