GIDS already declared development of FAAZ II which they claim would have range of 180 KM.
Right but the 100-180 KM range is based off of certain launch speeds of the fighter jet moving mach 0.7-1+. I believe for a SAM the FAAZ series would be a similar design except incorporating a much stronger boost motor to get the missile to a certain speed before the main motor takes over.
We should leverage the FAAZ series + our current in house indiginous AESA radar to develop a medium/long range SAM system to supplement the HQ9P.
