Multiple Independently Targetable Reentry Vehicle (MIRV) warhead is a collection of separate warheads. By contrast a unitary warhead is a single warhead on a single missile.

Dr APJ Abdul Kalam is the undisputed father of India’s missile programme. He was breathed life into ballistic missiles like the Agni and Prithvi. It is too exhausting to track Dr Adbul Kalam’s achievements to date. In the 60s and 70s he was a trail blazer in the space department. In the 80s, he transformed the moribund Defence Research and Development Laboratory in Hyderabad into a highly motivated team.

By the 90s, Kalam emerged as the Czar of Indian Science and technology and was awarded the Bharat Ratna and served as the 11th President of India 2002 to 2007.
