In the Agni series, India at present has Agni-1 with 700 km range, Agni-2 with 2000 km range, Agni-3 and Agni-4 with 2500 km to more than 3500 range.
Commenting on the trials of INS Arihant, Chander said the vessel will be launched for sea trials within a month or two and it will be firing the indigenous BO-5 missiles, which have a range of around 700 km.
He said the development trials of the BO-5 missile were completed in January 2013 and it is ready for being fully integrated with the indigenous nuclear submarine.
On the Ballistic Missile Defence system, he said the first test of the frozen configuration will be tested within a month's time.
To a query on India's anti-satellite capability, the DRDO chief said the kill vehicle (missile) of the BMD along with the launcher of the Agni missile can be used for demonstrating this capability but so far, the country does not want to showcase it as it is against having debris and other unwanted materials in space.
