Indians have evaluated the F-16 time and time again. They have even qualified test pilots who have their masters theses done while doing their test pilot courses at Edwards AFB since the 80s or 90s, I'm forgetting the exact decade, but they've flown it numerous times. Yet the F-16 is ahead of any major Chinese platform out there, in almost all aspects. Chinese jets in PAF service often go through numerous upgrades which also cost a lot more than just getting the baseline Made in China aircraft.
2 additional squadron buildings being constructed with a whole lot more. Yes there are people who know what kind of work is happening at Bholari. It is just limited info that can be told for now. Some are happy with that, most want to know more.
Negative, Kamra was a hit and trial for Vipers which worked well for the 80s and 90s, yet the embargo affected the decision in keeping them there hence the move to Sargodha was more economical not to mention the good number of Vipers that crashed in a span of 8 years. And no it was not the most dumbest assumption, they have employed people who make the best decisions for employing platforms over there.
Block 72s or Vipers or used Vipers etc etc....to accommodate 2 more fighter squadrons. What and when are the arrival of whatever jets, I'm unaware of it as they won't say more. And please I'm no sir, not that old yet.
Cheers !!!
