Very practical answer.
I do not know why some of us want to make bombastic claims about our indigenous capability thereby allowing others to question our credibility.
I want India to make the F22 equivalent, Ford aircraft carrier equivalent, Yasen/Virginia class SSN equivalent, the 20 Megaton Tsar Bomba equivalent etc.
All within the next two years.
I will be the happiest and others also if we achieve it. But in reality are all these technologies within our reach in the next couple of years.
Do we want to emulate the Pakistanis who make outlandish claims about their Super Duper Science and Technology capability. Like building an 5th generation fighter without even having designed and developed a basic trainer aircraft.
Let's face it. The Akula is an quite advanced SSN by our standards. How can we deride it when we are yet to achieve even 75% indigenisation on the Scorpene submarine. Have we developed an fully indigenous conventional submarine yet.
I and the nation want India to be able to achieve self sufficiency in all types of defence products. But since we are a young nation, we should give ourselves some time to master the various advanced technologies. So we need to be patient and work hard towards our goal.
If someone does not like the Russians it's OK. But do we have an alternative. Will the US share nuclear submarine technology with us?. If Yes, and the terms are liberal then we should build the latest contemporary SSN's with Washington's help.
To people who question our defence planners. Please get Washington to collaborate on SSBN's and SSN's and offer us the latest submarine nuclear reactors which last the lifetime of the submarine.
Let us try to maintain the quality of the discussion and not embarrass ourselves by very fan boyish claims.
