Norway's currently operating 52 F-16AM/BM Block 15 MLU, these aircraft has some Block 50/52 technologies in them, but honestly, they aren't anything special.
Yes, they will likely be sold, and Pakistan is an option if it should ask for them - but, and this is the major sticking point; while our AM-1, AM-2, AM-3 and AM-4 are on track, those four F-35 are the only four that have so far been ordered. 52 are planned, to replace our F-16s on a 1-1 basis, but so far only four F-35s have been ordered.
16 have been cleared for purchase but no orders placed.
This already puts our F-16 replacement plans in doubt, but to make it worse, our F-16s to remain in service until at least 2024 as 6 f-35s will arrive every year, which the first two arrive in Norway in 2016, this of course relies on the assumption that all 52 planned are fully funded. At present they are not.
Pakistan can order them once they are replaced, or even begin negotiations to secure them before they hit the open market, but they wont be leaving Norway quite yet.
These are our (and maybe your) F-16s:
Personally, I think there are better options for Pakistan, especially given the time frame.
