India has already tested the Submarine-Launched Ballistic Missile (SLBM), designated K-15, more than a dozen times and in January conducted the SLBM’s last development trial. The process of integrating SLBM with the INS Arihant, the indigenously-built nuclear submarine, is expected to begin soon.
This capability would complete India’s nuclear triad, making the country capable of launching nuclear missiles from air, land and sea. The triad’s other elements are the Agni missile with a range up to 3,106 mi., and the Mirage-2000, Su-30MKI and MiG-29 fighters.
Indian defense scientists are developing another SLBM (K-5) with a range of nearly 1,864 mi.
