Sir, there is a plan named AFFDP-2019 (Armed Forces Future Development Plan) which was planned and made into action years back by Musharaf, when KLB had nothing to do with Pakistan nor it will affect PDF modernization process. Yeah delays can take place of a few years, but the plan will keep happening as time passes by.
Nor it is gonna be financed by KLB, it will have its share in the defence budget and if needed extra funds from govt would be provided. Plus many of the things in the plan would be indigenous, and other weapon systems would be sourced from countries which can provide easy financial repayments terms.
PAF, PN & PA all have their share and nearly everyone has finalized the procurements or would do in a couple of years. Like for PN, next batch of frigates,corvettes are likely to be ordered by next year, submarine seems to be other things, which if ordered by next year would all be in the PN by 2019. Same case with PAF, AEW&Cs, air refuellers, JF-17s coming online, plans for further blocks in the pipeline, FC-20s coming by 2014-15 and more would be ordered once initial 36 come, new 18 F-16s would be there by end of 2010-11, the MLUs would then get started and if possible 2nd hand more to be ordered. So if these plans get going by 2019 both arms would be fully operational and at top of their capability.
PA is also upgrading, artillery being changed to 155 caliber standard as time goes by, tanks getting upgraded and new ones coming in. ATGMs getting upgraded. SFs going to division strength, air assualt capabilities getting stronger, air assets being procured. Attack helicopter being looked into, hope so in a year or so finalized. Plus lot of other things.
So these things have nothing to do with KLB as its just related to USA, even if they stop it we can still procure what we have planned for.
