Nuclear-Capable Agni-IV Missile Test-Fired Off Odisha Coast

India on Sunday, 23 December, successfully test-fired its nuclear-capable long-range ballistic missile Agni-IV, with a strike range of 4,000 km, as part of a user trial by the Army.

The strategic surface-to-surface missile was flight tested from launch complex-4 of the Integrated Test Range (ITR) at Dr Abdul Kalam Island, earlier known as Wheeler Island, at about 8:35 am, defence sources said.

Describing the trial as a “complete success”, they said all mission objectives were met during the test-fire.

All radars, tracking systems and range stations tracked and monitored the flight performance of the missile, which was launched with support of a mobile launcher.

Radars and electro-optical systems had been positioned along the coast of Odisha for tracking and monitoring all parameters of the missile, the sources said, adding two naval ships were anchored near the target area to witness the final event.

This was the 7th trial of Agni-IV missile. The last trial conducted by the strategic force command (SFC) of the Indian Army from the same base on 2 January 2018 was successful.

The indigenously developed sophisticated Agni-IV having 4,000 km strike range is a two-stage missile. It is 20 metre long with a weight of 17 tonnes, they said.

The state-of-the-art missile is equipped with modern and compact avionics to provide high level of reliability and precision.

It has the latest features to correct and guide itself for in -flight disturbances, they said.

The accurate Ring Laser Gyro-based Inertial Navigation System (RINS), supported by highly reliable redundant Micro Navigation System (MINGS), ensures the vehicle reaches the target with accuracy.

The re-entry heat shield can withstand temperatures in the range of 4,000 degrees centigrade and makes sure avionics function normally with inside temperature remaining less than 50 degrees centigrade.

Ballistic missiles like Agni-I, II and III and Prithvi have been included in the arsenal of the armed forces, giving India an effective deterrence capability.
