All their F-16's are not at par with the ones even Pakistan or UAE has. They have Block 30's and 40's as well.It's a very good multirole fighter and nobody wants to give it up easily.
Pakistan already has 310 Al-Khalid's. 9 Al-Khalid 1 in 2016. So these 30 are in addition. And also is the procurement of Al-Khalid's completed and will they be upgraded to Al-Khalid 1 standard?
yep. Problem is they can win against competent enemies only in movies and dramas. Their metal is only proven against pathetic adversaries( Iraq, Vietnam and Afghanistan).
