For J-11B lighter colored radome indicate the switch to AESA but we are unsure of variant.
Since the J-11BG is never seen carrying PL-15 it is possible that it is an air cooled variant that allows for easier integration without the need for additional plumbing modifications and therefore is not as powerful as what’s used in J-16.
Do we have any pictures of J-20 production lines.

"the engineer"
There are no declassified j20 production line photos that I know of. But it's nothing special, kind of like the j15 line but more advanced. Not as advanced as the publicly shown f35 line.
What are the pros/cons of using a high thrust single engine on an aircraft versus low thrust double engines (apart from naval requirement of two engines and maintenance)? i.e. F-16/J-10 versus Eurofighter. What if EF was single engine or J-10 double engine.. what would change?
Benefit of single engine: cost, ease of maintenance since there is only one. In case of internal weapon bay more room for payload.
Benefit of twin engines: greater reliability, greater thrust.
It's better to lose AN engine rather than THE engine.
Two questions about aircraft designations:
1) We know there is a Y-20A and a Y-20B, but is there, strictly speaking, a "Y-20"? Likewise, for the tanker variant, is the designation YY-20 or YY-20A?
2) Is the upgraded J-11BH designated J-11BHG or J-11BGH?
1) We know there is a Y-20A and a Y-20B, but is there, strictly speaking, a "Y-20"? Likewise, for the tanker variant, is the designation YY-20 or YY-20A?
2) Is the upgraded J-11BH designated J-11BHG or J-11BGH?
1) I've seen Y-20 used to refer to the ones with D-30 engines, while Y-20A refers to the ones with WS-18. No idea if that's official though.
2) BHG seems to be the way, which makes sense as they were naval before they were upgraded (BH->BHG), instead of upgraded aircraft converted to naval aircraft (BG->BGH).
From my understanding, the first prototypes were Y-20 and AFAIK the last two 578 & 579 were the first Y-20A. But much more decisive is the question of what was changed, so that even a new name was assigned, while for the J-20 no new letter was assigned.
