Meanwhile, the Indian Navy’s Advanced Technology Vessel project was taking shape in the 1990s. This fructified with INS Arihant getting inducted in August 2016. The second in the class, INS Arighat, was launched in November 2021.As reported by this newspaper on August 11, a government green light to enhance the attack capability of the Indian Navy is due this year through the manufacture of nuclear-powered submarines.
