Since last few months no crash recorded regarding Mirages. The crashes were mostly of Mirage-III variants this means that Mirage V of PAF are still safe to fly. However some extra work has been done to make Mirage III better.
The first preference should be to re[lace Mirage III old versions and F7s ( which are perhaps already being replaced with JF17s mostly).
F7s and F7PGs were produced with short life cycle, so next threat is of F7PGs.
Sir or financial constraints can't justify or defense gaps. IAF shall be more potent with induction of Rafaels, SU30 upgraded with better operational availability, Mig29 further upgrades, Jaguars being upgraded. Even in mid term we observe induction of F35 .
At least what we should do is to make JF17 block 3 more potent at least for AD, meanwhile for limited interception, deep penetration the Su35 or any Chinese flanker should be acquired.
