Bhubaneswar: The Defence Research & Development Organisation (DRDO), successfully test fired AGNI-IV, a nuclear ballistic missile in the Agni series, today, from the Dr. APJ Abdul Kalam Island (previously Wheeler Island) on the coast of Odisha at 8:35 am. This was the seventh test trial of Agni-IV. The last trial conducted by the Strategic Force Command (SFC) of the Indian Army from the same base on January 2, 2018 was successful.
The missile is having a strike range of 4,000 km, with a wight of 17,000 kg (17 tones). It is about 20 mt (66ft) long with two stage solid propellant engine. It comes under Intermediate Range of Ballistic Missile. The DRDO has designed it and is manufactured by Bharat Dynamics Limited.

To ensure that the vehicle reaches the target with accuracy it has been equipped with Ring Laser Gyro-based Inertial Navigation System (RINS), supported by highly reliable redundant Micro Navigation System (MINGS).
The re-entry heat shield can withstand temperatures in the range of 4000 degrees centigrade and makes sure avionics function normally with inside temperature remain less than 50 degrees centigrade.
The missile was test-fired as a part of user training exercise and this missie is not yet deployed, said defence sources.
