Named INS Arihant, the submarine, which according to NDTV can target Chinainfo-icon, had been thirty years in the making and can "now be considered a fully functional underwater ballistic missile delivery platform".

"In an era such as this, a credible nuclear deterrence is the need of the hour," said the Indian premier. "The success of INS Arihant gives a fitting response to those who indulge in nuclear blackmail."

The newly launched submarine, NDTV adds, "completes India's nuclear triad by adding maritime strike capability to land and air-based delivery platforms" -- a feat Pakistaninfo-icon had already achieved in 2017 with the launch of Babur-3 missile.

In March this year, Pakistan carried out another successful test of the nuclear-capable Submarine Launched Cruise Missile (SLCM) Babur and announced that it has attained 'Credible Second Strike Capability'.
