MK, to be honest with you, you aren't making sense anymore. In one sentence, you are saying the SU-27 in a bombing role, will not be able to tackle the enemy aircraft. But then, you constantly make the case for JH7A......which is a two decade older modified design for SU-25 (much older plane). If the SU-27 (modified to the teeth as J-11D) can't hold its own, how the heck could a 4 decade concept hold its own???
J-11D is the best option for the PAF decent numbers and affordable. Or, 44-64 (2-3 squadrons and trainers) of SU-35. That's it. Or 80-100 FC-20, either combination would help. Plus add 18 new -16's block 52 or 30-ish used -16's (still cheaper than 18 brand new ones).
JFT's loiter time is smaller......but if its placed closer to the border for interception, an airway lasts for a few minutes, if that. You know that. And JFT can be VERY effective IF places closer to the border and positions properly. Hell, your F-7's and Mirages can be good assets IF positioned properly, close to the border so their Sidewinders can lock onto the inbound jet's the second they take off. You defeat SU-30's or anyone else's bigger radar advantage.
One thing the USAF teaches it pilots again and again is that you win half the battle when you force the enemy to fight under your rules. In which case, the second a -16 forces a -15 into close combat, the -15 immediately uses it bigger radar advantage. The results then are usually in Viper's favor. Same thing for the PAF, deploy the JFT, the Mirages and F-7's closer to the border so you get maximum out of them.
Like I said before many times, the planes to acquire more 4.5 generation aircraft are on the table. The weight was to find out what India gets and this was buying time for the PAF too, as they wanted to see FC-20 and J11D getting matured up. Now you also have the Russian option for the SU-35 (great jet). So options are open. A call will be made soon. Got to have the patience. The wasted time since the 90's can't be returned but hey, no harm no foul. Every-time is right when you decide to course correct yourself!!
