Agni-5, India's longest range nuclear capable missile, was successfully test fired from the Kalam Island off Odisha coast today by the Defence Research and Development Organisation or DRDO. The intercontinental surface-to-surface nuclear capable ballistic missile, the latest in India's "Agni" family of medium to intercontinental range missiles, has been through four trials now. The Agni 5 missile, with new technology for navigation and guidance, gives India the strategic depth it needs to contain its enemies, say scientists. After a few more trials, it will soon join India's military arsenal.
