Arihant-class Nuclear Ballistic Missile Submarine

The Arihant-class (Sanskrit, for Slayer of Enemies) is a class of nuclear-powered ballistic missile submarines being built for the Indian Navy. They were developed under the US$2.9 billion Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines.

The lead vessel of the class, INS Arihant was launched in 2009 and after extensive sea trials, was confirmed to be commissioned in August 2016. Arihant is the first ballistic missile submarine to have been built by a country other than one of the five permanent members of the United Nations Security Council.
