As we learn from the Hindustan Times, India has today entered the club of nations that have nuclear subs.
The INS Arihant (Arihant means destroyer of the enemy) was entirely built in India. The submarine was named in a symbolic launching ceremony at the Indian Matsya shipyard.
The pictures provided by the Hindustan Times display Russian built submarines (see below). So it is not actually clear to us, how the Indian Arihant looks like.
However, thankfully the Russian are ready to provide some technical information at ITAR-TASS who writes:
Submarine, which received the eloquent title “Arihant” which means “destroyer of enemies, has a displacement of about 6000 tons with a total length of the shell in the 104 meters. It is equipped with a capacity of 80 megawatt reactor, developed by specialists of Center of Bhabha Atomic Research – a leading national research and design agency industry.
The fuel unit uses highly enriched uranium, produced at specialized Department of Atomic Energy, in force near the city of Mysore. According to preliminary calculations, the nuclear submarine power plant will enable it to develop the speed to 30 knots and in the autonomous navigation of up to 90 days.
