The Agni missile series is a family of medium to intercontinental-range ballistic missiles developed by DRDO. The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Programme (lGMDP) and tested in 1989. After its success, the Agni missile programme was separated from the IGMDP.
Agni-I is a medium-range ballistic missile with an operational range of 700-1000 km. It was launched in 2002 and is currently used by the 34 Missile Group at Secunderabad under the Strategic Forces Command (SFC) of the Indian Army.
Agni-II is the second strategic ballistic missile of the Agni family, which was launched in 2010. It has an operational range of 2000-3500 km, which means it can reach any part of Pakistan and most parts of South and Southeastern China.
Agni-III is an intercontinental-range ballistic missile that was inducted into service in 2011 as the successor of Agni-II. It has an operational range of 3500-5000 km and can reach targets deep inside neighbouring countries, including China.
Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime. It is an immediate-range ballistic missile with an operational range of 3000-5000 km. It is capable of striking targets in nearly all of mainland China if launched from northeastern India.
Agni-V, the newly launched missile in the series, is a land-based Nuclear MIRV-capable Intercontinental Ballistic Missile with an operational range of 7000 km-8000 km. It was launched under the name of Mission Divyastra and can hit multiple targets simultaneously.
