It would be great to see J-10Cs in PAF livery but somehow, I doubt PAF will induct them. From the time of placing order, getting it modified for PAF requirements, receiving them and forming squadrons, training all the ground crew/pilots for these fighters, and understanding the J-10Cs inside-out; it could take 7-10 years before PAF could use them effectively. Correct me if I'm wrong as my knowledge is a bit limited.
I think, like some of our well known members on PDF, that PAF's best options are to try and acquire more JF-17 Blk 2s -- Blk 3 would be great -- at a faster rate than 12/year, if the production can be accelerated.
If the Trump administration is feeling kinder, some extra F-16s would be welcomed by PAF too.
