Initial Plans are for 2 squadrons, if everything is well then that would be build upon. there is a new base and another being built.The PAF never bought a new platform only to stick to 36 planes.
If not for Pressler, the PAF was looking to have 150 F-16s (read it here).
Otherwise, every fighter bought on Pakistan's dime came with a procurement plan for at least 90 units:
If the J-10CE is coming, the PAF will not stop at 36 aircraft. It will stretch it to at least 90 units and, possibly, push it up to 150 if the funds allow it. If you actually speak to any PAF person who had been involved in the procurement process, they'll tell you this point.
- F-6 was ~180 units
- Mirage III/5 was ~90 units (before the used planes in the 1990s)
- A-7 Corsair II plan was 110 units
- F-16 plan was ~100 units plus an option for 50 more (pre-Pressler)
- JF-17 was 150-200 units
This is a big reason why they didn't push for the Typhoon, Rafale or Su-35. It wasn't that they couldn't afford to acquire 1 or 2 squadrons, but to get the most out of the platform, you need it in numbers: 90+. But at that scale, not every fighter is feasible enough to acquire.
I would not be surprised if we see 5-7 squadrons (if there ever is a new fighter). Right now I haven't seen any financial efforts being made towards a purchase, when we see that then it would be imminent.
Not a ray of hope but there will be.
