BTW curious to know , how much this procurement cost us. This is a heavy ticket item. After 8 submarines deal, this perhaps the most important buy among all the branches of Pakistan's military.
To me in the last two decades, our most important buys have been 18 F16s block 52 along with AIM120C5s, which we got it thru CSFs. Then, it was the 8 subs deal with China. Not the type 54As or Turkish Milgems but the submarine deal is the single most important strategic weapon systems which we will be start getting by 2024 and lastly these HQ9 SAMs. Buys like these directly upset enemies war plans and their thinking.
Other important buys have been Saab AWACS but they are more like a force multipliers. J10s will be good addition as well but we will be having similar system like them already i.e.block 3 jf17 so to me, after block 52 and aim120c5 bvr missiles, HQ9 procurement stands top of it along with the 8 subs deal in the last 20 years or so.
