PAF should not waste money on western sanction prone fighters. also they are too much expensive... just go for thunder and FC20 upgrades and hope for an 5th gen fighter from china after 2020. nothing else needed. yes navy should buy some 24 or 36 fighters but i would say they should also prefer FC20 and JF17.
lol without any doubt i can say f-16's ,dun know what type of love and attachment Paf have with these f-16's, i bet you u give them 100 chances and 99 out of hundred times they will go for f-16's and the rest one time is for guess wat again f-16's lol but new ones
