With the test, India became part of a small group of nations having the capability to fire a nuclear missile from land, air and undersea. The K-4 missile was tested from submarine INS Arighaat off the coast of Visakhapatnam on Wednesday,

India has tested a nuclear-capable ballistic missile with a range of around 3,500 km from a nuclear-powered submarine in the Bay of Bengal, in a major boost to its nuclear deterrence and strategic capabilities,

Demonstrating its strategic capability and maritime deterrence, the Indian Navy for the first time carried out a test firing of the 3,500 Km K-4 long range ballistic missile from the newly-inducted indigenous nuclear submarine INS Arighaat.

Launched from the nuclear-powered submarine INS Arighaat on November 27, 2024, this test marks a milestone in the country’s journey to enhance its second-strike capability.

The test is highly important for validating the country's second-strike capability. In August, the Indian Navy inducted the submarine in the Vishakhapatnam-based Ship Building Centre.

The Indian Navy carried out the test firing of the 3,500 Km K-4 ballistic missile from the newly-inducted nuclear submarine INS Arighaat on Novmber 28.
