Check out some of the payload options of the F-35, this is what the J35 is competing against interms of payload :
First things first, this is the J-10 thread, why ya here? Move this to
J-35 carrier fighter (PLAN) thread at least.
Secondly, J-35 isn't really to match the F-35. It does not need to drop bombs or do EW, the J-16, J-16D, J-15 and J-15D can do that already. In a head-to-head fight, my bets on the J-35, more max payload won't do much if the IWB is that narrow.
