About INS Arihant:

The capability of being able to launch nuclear weapons from submarines has great strategic importance in the context of achieving a nuclear triad, especially in the light of the ‘no first use’ policy of India.
INS Arihant is India’s nuclear-powered ballistic missile capable submarine, classified under the SSBN programme.
It was commissioned in 2016.
INS Arihant is presently armed with K-15 SLBM with a range of 750 km.
The next in the class, INS Arighat is reported to have been launched in 2017 and is said to have been undergoing sea trials.

The SSBN is a hull classification symbol for nuclear-powered ballistic missile carrying submarines.
Operations of the SLBMs from the SSBN are under the purview of Strategic Forces Command which is part of India’s Nuclear Command Authority.

The family of indigenously developed Submarine Launched Ballistic Missiles (SLBMs), sometimes referred to as K-family missiles are codenamed after Dr APJ Abdul Kalam.
Under the SLBM family, missiles of various ranges have been developed including K-15 also called Sagarika, which has a range of at least 750 km.
India has also developed and tested the K-4 missiles from the same family, which have a range of 3,500 km.
