So you don't actually know what the maximum payload on a wing hardpoint for a Flanker-sized fighter is. I don't either, but I'm up front about it. I certainly don't outright exclude the possibility that a Flanker-sized fighter wing can carry a 2,500kg load. I know that even F-16s routinely carry the standard US 600-gallon drop tank on the nearest wing hardpoints that including fuel, pylon and dry weight comes to >1,900kg. I can only assume an F-15, Su-33, or J-15 wing could carry even more weight.
No, I never claimed to know what the max wing hardpoint payload is, but I don't need to. No Flanker or J-11X has ever carried anywhere near a 2500-kg load on a wing hardpoint, so by virtue of retrospective inference it can be claimed, with a high degree of confidence, that the J-15 would be no different.
Bringing up the F-16 as a rebuttal isn't very useful here, since the hardpoint capacity varies between different models of fighters (due to different reinforcing requirements for the airframe). For instance, a load that is managed by a J-16 hardpoint may not be tolerated by an equivalent hardpoint on a J-11BS, despite the two aircraft being very similar in dimensions and weight.
Of course, dimensional restraints have to be considered as well.
Both these statements here constitute your personal opinion. There is no way you can argue around this point, regardless of how emphatic you are about it. Even if we have only seen it so far on the H-6, this does not constitute an argument that only the H-6 is able to carry this missile.
My point with the H-6 wasn't to argue that it would be the only platform to sport the YJ-12. I fully expect the J-15S (and perhaps the J-16) to bear the weapon on its centerline hardpoint. I was merely reiterating the observation that, thus far, the missile has been seen aboard solely the H-6.
