The Arihant class (Sanskrit, for Killer 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.
In December 1971, during the Indo-Pakistani War of 1971, the US President Richard Nixon sent a carrier battle group named Task Force 74, led by the nuclear-powered USS Enterprise into the Bay of Bengal in an attempt to intimidate India. In response, the Soviet Union sent a submarine armed with nuclear missiles from Vladivostok to trail the US task force. The event demonstrated the significance of nuclear weapons and ballistic missile submarines to then Prime Minister Indira Gandhi. Following the 1974 Smiling Buddha nuclear test, the Director of Marine Engineering (DME) at Naval Headquarters initiated a technical feasibility study for an indigenous nuclear propulsion system (Project 932).
