before the pakistani involvement in the jft programme-- it was merely an upgraded f-7 [called sabre2]
paf engineers studied the design and came up with proposals--after that paf engineers and experienced f16 pilots joined hands in upgrading the requirements -- so , rumours of supplying an old f16 jet as well as test pilots which could easily compare the performance of jft protypes with f16a surfaced-- f16 influence is apparent in the jft
r&d offices might not be present , initially at kamra , however it was repairing overhauling modifying and maintaining ALL our inventory at that time-- so the engineers went directly to the r&d offices in china , rather waiting for the setup to mature in pak kamra--- the number of engineers increased and made a mini pakistan city their.
99% people here are not related to the jft programme, on top of that due to chinese secrecy programme , we dont find many links on the internet anyway.there are SO many subsystems in a fighter, that you cant count them on your fingers-- only now, some of the systems have appeared in the media and most of them are produced at kamra.
nabil does post some enginearing tidbits improvements in jft from his pakistani sources
imran did post 7 posts together describing the pak. compaines aswell as their long subsystem production lists-- i have to say it was quite impressive
tempest provided some info on the inital klj7 radar
frankly, i dont even care if we didnt contribute anything except money, in this programme--- the end result is , we are gradually able to manufacture all parts of jft in pakistan within 5 years--initially it was just assembly line and now even the avionics packages are being produced in kamraa--not to mention the great exposure presented to our engineers in this process-- r&d is still going on for a twin seeter and stealthy version of jft aswell as j10b--- that too after the proposals from pakistan-- you got to understand , a person can only provide proposals WHEN he knows what he is doing
this jv has provided a very strong basic foundation in r&d, production of a modern fighter-- which will eventually help our aircraft industry
go through the jft info pool--- however their is no official data on this subject from a proffesional that we can point you to other than scattered info of different systems being produced alongwith r&d in pakistan.
