That's true. What I read is that H-6K is a self funded project by XAC, that's why they don't mind showing it. It doesn't have the high level classification that J-10B or J-11B have.
I wouldn't put that much faith in the latest Pentagon report. Its quality isn't that great, lol. I've written in the past about the inconsistencies that I see in it.
Pakistan has basically handed the control of Kashmir to China according to a recent NY times articles. If it still needs to fly further West (even assuming that added distance from Kashmir is still not enough for CJ-10K). If China escorts it with a couple of J-11s providing escort, which of these stans are going to stop that? But in my opinion, CJ-10Ks range will be enough that it's not needed. If CJ-10K is based on KH-55 that China purchased as speculated, do you think its range will be closer to that of KJ-55's 3000 km or Pentagon's estimates of 1500+ km. Which btw, is based on a test from several years ago. And if you don't think it can fly far enough to hit Guam, that's fine, they can hit Krgystan's base.
Please don't use this as a springboard to China vs USA. Let's stick this to targets H-6K can hit and whether it could be useful in its role.
