Indian Navy likely to commission third indigenous N-powered submarine ‘by this summer’

India's sea-based nuclear deterrent is set to be significantly bolstered with the upcoming commissioning of INS Aridhaman, the third indigenous Arihant-class nuclear-powered ballistic missile submarine. This larger vessel, capable of carrying long-range K-4 missiles, will enhance India's "second-strike" capability and move it closer to achieving continuous at-sea deterrence.
