A Recent news item surprised me, it was about the launching of the

india's first nuclear submarine "Arihant". A lot of secrecy seems to

have been maintained. This should have been a big project and a lot of

people might have been involved in it, and still only bits of info

seems to have leaked to the mainstream media. This in itself seems to

me , an achievement. Now India also has become one of the countries

that has the capability to manufacture nuclear submarine(this is a

small submarine in comparison to what is possessed by the big developed

nations).I'm Sure this kind of project might have been guessed by the

magazines devoted towards defence and security.But the general public

probably do not access to them, due to their high cost?.
