  • India test fires K-4, a 3,500 km nuclear-capable missile meant for Arihant submarine
  • K-4 is the most potent missile that India can fire from a submarine, giving the country unprecedented second-strike capability and huge deterrence power.
  • The missile was tested Sunday from a fixed underwater pontoon on the east coast —it was fired off the coast of Andhra Pradesh.
  • The missile is being developed by India’s Defence Research and Development Organisation (DRDO) and is to be fitted into the indigenously built Arihant-class nuclear-powered submarines of the Indian Navy.
  • This is the fourth time the Defence Research and Development Organisation (DRDO) has attempted to test fire the missile since October, but various climatic conditions prevented it.
  • Reports have said that the K-4’s circular error of probability (the radius of the missile’s point of impact which is also a measure of the efficacy of its guidance systems) was 40 meters or less. This makes it ideal to strike targets from stand-off ranges.
  • While India does operate a submarine launched ballistic missile (SLBM), the K-15, it has a limited range of just about 750 km.
  • DRDO sources say that the research agency is already working on a much longer range missile, the K-5, which can hit targets 5,000 km away.
  • In November 2018, India had announced that its first nuclear armed submarine Arihant had successfully completed its first deterrence patrol, heralding India’s entry into an exclusive club of powers with land, air and sea-based nuclear weapons delivery platforms.
