INS Aridhaman (SSBN 82) (lit. 'Perpetually Victorious') is a nuclear-powered ballistic missile submarine, and the third of the Indian Navy's Arihant-class submarine. It is designated S4 Strategic Strike Nuclear Submarine. The 7,000-tonne vessel was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in the port city of Visakhapatnam. It is an upgraded variant of the Arihant-class submarine.
The submarine was quietly launched in 2021 and little has been publicly announced about its capabilities and current status.
