Moving a step closer to completing its nuclear triad, India on Sunday successfully test fired a ballistic missile, with a strike range of around 1500 kilometres, from an underwater platform in Bay of Bengal.

“The medium range K-5 ballistic missile was test fired successfully today from an underwater pontoon and all parameters of the test firing were met,” DRDO chief V K Saraswat told PTI from the undisclosed test area.

The nuclear triad refers to the ability to fire nuclear-tipped missiles from land, air and sea.

Saraswat said that the development phase of the K-5 missile, which is a submarine-launched ballistic missile (SLBM), was over and it was now ready for deployment on various platforms including the indigenous nuclear submarine INS Arihant which is under development.
