I am not denying the products which you have stated above. I am just wanting you to see the patented technologies by DRDO. A handful of them perhaps, An R&D institution such as this is expected to do more. A nuclear submarine, a Missile blah blah blah!! it is not our invention. We have got the technology which is inherited to us in different forms. not that we created it..
Nuclear submarine, aircraft carrier, ICBM inherited to us? And they are blah blah? What are you talking about? Do you know how much R&D required to build them? How many countries did those? Do you expect India to invent something like space warship or robot army? What is that exactly?
I do not know how many countries did such creation except US!
Those companies got many patents spend much more on R&D than DRDO/ISRO/DAE etc. Anyway...
DRDO registers jump in filing patents
Achieving something like them are great honor and achievement for any institution, not just another day. See how Indian navy chief called induction of Indian made stealth frigate as a "red letter day for the entire Indian armed forces". The people designed and build the ship should be more happy.Building a nuclear submarine or an ICBM might be a bigger thing to you but its just another day at the office for the scientists.
