New Delhi, Oct 19: INS Arihant, India's first indigenous nuclear submarine on Tuesday was inducted in Indian navy, though Defence Ministry has maintained silence over the same. Navy and Defence officials believe that  such silence was "customary" as the project is 'top secret'.

Sources say that even the Navy is not aware of the submarine's movements and locations, which are decided by the orders from the highest level.
