The issue is, because of the rate at which it closes in at, you will need an exceptionally agile missile, like CAMM/IRIS-T. This is why we mention, the biggest weight will be carried on the shoulder of really agile MR/SRSAM's, not massive poles like HQ-16/9. This time its not a matter of interception ranges, rather, reaction speed. We need to plug that sr-mrsam gap ASAP with systems like CAMM and co which can get out fast and kill. The MRSAMs were also what did most of the work on the Indian side too, QRSAM/Barak 8.
PA/PAF AD currently looks like this
LRSAM
HQ-9P/BE
HQ16FE
160km+
MRSAM
HQ16B/EV
FD2000
125km+
SRSAM
SOME HQ-16A
40km
CIWS
SPADA
15-20km?
This massive gap between MRSAM-CIWS is the problem.
The reality is the HQ series are derived off of older soviet long range designs, suffering from the same limitations. A one missile does all approach, if you look at other systems, PATRIOT, IRIS T, S400 etc, they all use different missiles for different target type, because u simply cannot just have one missile that will be amazing against hypersonics but also long range fighter engagements etc. We need to plug that gap
