We do Najam Bhai ? There are only a few dozen of them pitted against a little under 300 Su-30 MKIs and the odd number of Mig 29s and Mirages.No we don't.
Here is the summary...
1- PAF don't have intra-regional doctrine neither we have strategic depth.
2- Tankers for us are handy in case of strike/longer patrols (which is need/situation based). Close proximity of FOBs and operational bases practically rule out the need of tankers for us.
3- Regarding F16s, we have them in numbers. For air-defence role their loiter time is already good. Buying dedicated refuelers for F16s just don't fit in the scope of PAF ops.
I ask this because I remember reading a blog post by Kaiser Tufail on the Kargil War and if I remember correctly he mentioned how only whenever the F-16s would fly the adversary aircrafts would turn back to base but the same effect wasn't there when we flew our F7s or Mirages.
