Not entirely true. We can get a good idea in Shaheen type exercises. Given a certain stealth design component, locally produce a small Thunder iteration and field it in a Shaheen type exercise. Note the performance. Collect data. Reach a decision. Repeat. That's how you slowly build capability. Now, the good news is, we have a J-31 prototype flying around. Put the airframe through various scenarios in Shaheen, Anatolian Eagle and other exercises. And compare it against Flankers backed by long range AEWACS and Chinese and indigenous VHF/UHF radars.
Similarly for sensor fusion. Instead of trying to copy the F-35 JHMCS, involve the aces from CCS and pilots from various squadrons. Ask them how we can help you with situational awareness. Do usability testing. Create mock ups. Gather data. Analyze. Make decision. Repeat.
And here is the bottom line: you can do all of this without first creating a university. You need structured thinking and an experimental approach towards program management. When you have learnt the lessons and formed a core group of people, then create academic programs to transfer that learning to the next generation.
