Hq20 anti stealth and this lines up with what this guy says and the trio says
Just anti-stealth is a bit of a narrow field, though China is most certainly acting rich here (HQ-12(A), HQ-9C, HQ-19, HQ-20). That's likely more of a more self-sufficient medium range air defense system.
Can HQ-20 be replacing HQ-12(a) series in production? (assuming A is refresh to already produced units)
Hq9c launch. Looks like the ground version doesn't have the booster like hhq9c wonder why is that? and if that negatively affects mobility and range.
...but will help a great deal inner edge of engagement envelope and how fast missile can develop proper G forces.
It's a bit premature to make conclusions, both versions can be available both ways.
I'll bring up again the S-350(sort of HQ-20/HQ-9C analog) again - which has both shorter missiles(primarily meant to be used on navy corvettes and as s-400 anti-saturation missiles, but absolutely usable on S-350 launchers) and longer missiles (used primarily on navy frigates and meant to be main missile for s-350 batteries).
