India is finally close to operationalising, the long-awaited nuclear weapons, INS Arihant which has the capability to launch nukes from land, air and sea.
Although the land-based Agni ballistic missiles as well as fighter bombers configured to deliver nuclear weapons but with Arihant which will cover the sea leg, the big operational gap is filled now.
Sources said that the country's first indigenously-constructed nuclear submarine INS Arihant (which means annihilator of enemies), propelled by an 83 MW pressurised light-water reactor at its core.
The submarine was commissioned into service in August after extensive sea trials since December 2014 and now it is all set to operationalize.
INS Arihant's 750km and 3,500km missiles are yet to compete with SLBMs (submarine-launched ballistic missiles) with ranges of well over 5,000km, but the completion of the nuclear-triad is critical for India.
The 6,000-tonne Arihant is, however, not yet fully ready but it has undergone a whole host of surface and "dived" sorties during its trials to prove its sea-worthiness.
