Nope,
A unit cost for F-16 Blk 52 is $ 34 Million. Pakistan was paying $ 700 million for 8 aircrafts .. that is 87.5$ per plane.
So what is extra $53.5 million for ? These are for spares , engines etc.
Now J-10C cost $30 Million per unit. But J-10 is a new aircraft where as F-16 is a fully integrated aircraft that has been service for 35 years in, No pilot or crew training required, no bases with overhauling equipment required.
A similar deal for J 10, will at least cost twice as much as F-16 to integrate in PAF.
