Not a complete copy, I'm sure there were modifications and especially hq9B must behave differently but some seem to be claiming these sams didn't have inspiration from other systems which seems dubious. hq9 has been around and been upgraded enough that I don't think it has the same performance as s-300. I don't know the details of the competitionAre you saying HQ9 is the copy of S-300 Far from it In Turkey missile competition in 2013 FD2000 a dumb down version of HQ-9 score perfect score of 5 missile 5 hit beating patriot, Aster 30 and S-300
But because pressure from US and EU and Chinese refusal to give the source , in the contract was scuttled
And that's not possible because?
