No, i just purely speculated since we purchased first 20-25 Nodong 1 and 2 TEL in Early 1997 and called it Ghauri, after that and serious shortcomings of missiles were found since ToT was established, we requested China to help improve and make it a working weapon system. it took 3-4 years only then a re-born Ghauri was launched and deemed successful every other test before 2002 were failure.
it took lot of time for technicians and engineers to absorb the chinese provided Tech. in mean time since Ghauri was nonfunctional as a weapon and Pakistan`s predicament Chinese offered Ghaznavi (off the shelf) and Shaheen (CKD form).
Our indigenous achievement is Abdali SSM
so by now you could understand we are not manufactured with R&D. we are learning hands on and absorbing and this is what we can do.
by the way latest fatah series is also inspired.
I am amazed as some posters think that we have the capacity to do R&D and develop Missile systems. we do not have the base or even wind tunnel to test proper mathematics via super computer.
we absorb and try to devise best possible utilization.
