The important thing is to increase the total number of J-20s right now. Performance enhancement can wait.Thanks. That's barely 130 kN. Puts it in the class of the F110-GE-129. For the J-10 that would suffice, but rather low for 5th gen aircraft. Maybe it has an emergency mode similar to the Saturn 117/117S but at the expense of MTBO?
I am wondering whether the max dry thrust in the WS-10C is higher than the AL-31. That would help with supercruise for the J-20.
