Sir, to understand the situation, think in terms of engines.
Super Mushshak -> Turbo Prop
K-8 -> Turbo Fan
??????????????????? <------- LOCTA
JF-17 B -> Turbo Fan + After burner with high operational cost
The question marks show a need for Low Operational Cost Turbofan with Afterburner (LOCTA - I made up this abbreviation). That's the role the F7-PGs are playing. ACM Sohail Aman felt the existing so called options for LOCTA were too gold-plated. In any case, since JF-17 has set the benchmark for low acquisition cost, any LOCTA will be required to fall between JF-17 and K-8 in acquisition cost in order to even justify it.
I think PAF should hunker down, and give PAC the task of designing its own LOCTA. I keep coming up with these wild projects for PAC and people keep laughing, but the fact of the matter is, they need to work on a real project with real results in order to actually grow an indigenous industry. Merely creating universities will change nothing. It is utter folly that the first indigenous aircraft by PAC will be a fifth gen aircraft. This defies logic and reality.
