While this guy is ex PAF, I’m not willing to believe these specs off the bat. I’m not an expert, nor am I privy to any inside information that this guy may have. However these two claims do not sound credible, where would they find the space and capacity for these extra hardpoints? Only way it would remotely be possible is if there were two pod hardpoints instead of one under the intakes, and the count is made to include two dual ejector pylons. That makes 7 + 2 pod + 2 extra from dual ejectors.
Even then the mach 2 max speed claim is questionable. Unless we see the DSI bump configuration changed in a meaningful way or some other major intake modification, I don’t see this happening. Indeed, it shouldn’t even be a big requirement.
I could be wrong, but what we’ve seen doesn’t indicate any of this. As for J-10, it’s a delta wing configuration, lower wing loading, with a bigger engine and its medium weight, we can’t upgrade our way to a medium weight strike variant JF-17, it’s design limited. J-10 should manage strike a whole lot better, and unlike block III, the advanced tech needed for survivability is probably already there and sufficiently mature, vs having to wait and integrate, then tweak, with the block III.
Also, J-10B/C should in practice not have a max speed of mach 2 either. Both JF and J-10 are limited to Mach 1.6-1.8 due to DSI configuration.
