India has successfully test-fired a 3,500 kilometre range nuclear capable missile that can be launched from a submarine. The test of the K-4 ballistic missile was conducted off the Vizag coast in Andhra Pradesh on Sunday. With this test, India has moved one more step towards the induction of this ballistic missile on the INS Arihant class of nuclear submarines. The missile was developed by Defence Research and Development Organisation (DRDO).
The three-metre-tall missile carries a nuclear warhead of over one tonne with a circular error probability far lower than that of Chinese ballistic missiles. Only the US, Russia and China have submarine-launched ballistic missiles of 3,500-kilometre range. The submarine-launched ballistic missile is the most important part of the air, land and sea nuclear triad and is at the front of India’s second-strike capability.
