Prime Minister Narendra Modi today announced the development of "Mission Divyastra" - an indigenously developed, landmark weapons system that alters the country's geopolitical and strategic position. The Agni-5 MIRV missile, developed by the defence research centre DRDO for over a decade, took its first flight today. The new weapon system has Multiple Independently Targetable Re-entry Vehicle (MIRV) technology, which ensures that a single missile can deploy multiple war heads and hit targets at different locations simultaneously.
