Indian navy is the 6th biggest navy in the world (well according to wiki).
Having a supercarrier is not the only condition to be a blue water navy. FYI only US have Supercarriers. Neither China has is building any or have any plans for future (I am not talking about fanboy stuffs on your forum, there is no official news confirming China has any plans for Super carriers).
Only US, Russia, UK and France has naval strength that counts to be a blue water navy.
True but that isn't a requirement for blue water navy.
Look IN is not blue water navy, it is an aspiring blue water navy. By 2020 it will be a blue water navy, i think even before 2015, India can make into a blue water navy and same is the case in Chinese navy.
