The nuclear-capable K-4 ballistic missile has been successfully test-fired by India at Vizag coast in Andhra Pradesh. The nuclear-capable missile having the range of 3,500-kilometre was developed by the Defence Research and Development Organisation (DRDO).
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 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.
