Indeed, I currently prefer to call it J-20B but maybe more due to a feeling of hope than logic.
I know and as such agree that J-20S or J-20AS is the much more likely designation, but I don't expect this to be a simple twin-seater aka trainer like a J-10AS or J-11BS but a fully operational type for other missions than the single seater. As such a J-20S or J-20AS following the previously common scheme seems IMO inappropriate and therefore I expect or at least hope for a J-20 variant that deserves the next letter which would be "B".
By the way, a very huge THANKS you to my friend Ugo Crisponi from
, who made my day with these wonderful J-20B - or J-20AS - profiles!
