Nothing grow in isolation neither technology nor industry or product. Politician and research agency do work as par country needs and Armed forces give requirement according to country capability in technological field. Markva Tank was a joke when it was first inducted by Israel Almost everything was imported and still lots of loophole but Israeli Army had foresight and believed in it by keep on adding new capability as well as local technology. On the other hand, IA want Arjun in hooks of trials so neither DRDO scrap the program nor start a new program for future requirements . IA neither abandon the project nor accept Arjun They are just keeping it in hook.
Galil rifle is a copy of AK-47 same as INSAS except 5.56 caliber which is given by IA. IA has never given clear requirement when its come to Gun just to keep DRDO in hook. ( single barrel. double barrel. interchangeable barrel 5.56, 6.9, 7.2, a total mess ).
IA gave GSQR for 100mm mortar which was impossible to fulfill ( specially made to ensure failure of Indigenous project ) everybody knows this from start that this project is going nowhere but it took Israeli to say it is impossible to build then after IA realized.
IA keep on insisting upon TATRA truck due to kick back money. They never rope in TATA or Ashok leyland despite of their repetitive request.
China's j-20 get IOC in 2017 ( one can say questionable) immediately they started serial production despite of jet is not a complete product and still built 50 jets by 2020 But same you can not see for LCA ( FOC in 2019), LCH ( IOC 2017 ), NAG ( zillions of successful trials) , Astra (completed trials 2017), Arjun, ATAGs, Dhanush, MSMC (few orders), AEW&CS ( 3rd not inducted, no follow on orders ), Killing own HTT-40 program.
In any foreign deal Armed force actively try to bypass Indian defense industry just to make sure that we should left deprived for technology and keep importing same junk for generation to come.
If Armed force keep on behaving like this then even in next 100 years despite of all technological advancement, our armed forces will remain beggar. They simply don't want to put their shoes in mud and keep lecturing like Megalomaniac
