So length-wise your guesstimate match the comparison picture I posted.I did a guesstimate some time back and came up with:
Length: 18m
Wingspan: 13.5 - 8.7
Weight (Empty) 16,000kg
Nothing scientific, and I could be well wrong.
Doesn’t seem quite right. WS-21 nozzles are bigger than F-119 nozzles on the illustration.
Not sure where you've gotten that from. Just because it's never been seen carrying such munitions doesn't mean it can't, especially given the J-35 will have a much greater multi-role emphasis compared to other stealth fighters like the J-20.It's a pity J-35 still lack the ability to carry big ground attack munition like F-35 does.
