INS Arihant was reportedly first commissioned into service by Navy Chief Sunil Lamba back in August this year, thus quietly inducting the 6,000-tonne submarine which completes India’s ‘nuclear triad’.
According to defense sources, INS Arihant was formally commissioned in August 2016 after PM Modi gave his approval, but India preferred to keep the news under wraps in a bid to maintain secrecy.
Though India has completed its nuclear triad, all three sources including INS Arihant gives India a second-strike capability.
INS Arihant is India’s first indigenous nuclear submarine and would command all ships of Arihant class. This includes nuclear-powered ballistic missile submarines that were launched in 2009.
It also involved agencies and establishments such as the Defence Research and Development Organisation (DRDO), the Department of Atomic Energy and the Submarine Design Group of the Directorate of Naval Design, besides private companies like Larsen & Toubro.
