Agni-4

The Agni-4 is a two-stage solid propellant missile with a length of 20.0 m and a launch weight of 17,000 kg. Reports suggest that the Agni-4 can be fitted with a 20 or 45 kT nuclear warhead, or a 200-300 kT fusion warhead.1

Agni-4

Early reports about the Agni-4 suggested that it may be a technology demonstrator between the Agni-3 and the ICBM range Agni-5.2 However, after a successful test in January 2014, Indian Army officials suggested that the missile would enter serial production, suggesting that it will play a role in the nation’s nuclear arsenal.3

Officials from the Defense Research and Development Organization suggested during the development of the Agni-4 that the goal was to have a range of 5,000 km.4 Still, the listed operational range of 3,500-4,000 km allows it to strike targets in nearly all of China, including Beijing and Shanghai, if launched from northern India.5 It has also been flight tested at 3,000 km in December 2014, establishing its minimum range.6 The Agni-4 is road mobile and carried by a truck TEL, unlike the Agni-3, which is primarily rail-mobile. The missile uses a combination of a ring laser gyro-based inertial navigation system and a redundant micro inertial navigation system for guidance giving it double digit CEP.7
