The Defence Research and Development Organisation on Monday successfully carried out the final test run of nuclear-capable strategic ballistic missile Agni-IV. With a range of more than 4,000 km, the missile was successfully test fired from Balasore, officials said.
The indigenously developed surface-to-surface Agni-IV missile is a two-stage weapon system. It is 20 metres long and weighs 17 tonnes. Agni-IV missile is equipped with 5th generation onboard computer and distributed architecture. It has the latest features to correct and guide itself for in-flight disturbances.
Agni-I, II and III and Prithvi are already in the arsenal of the armed forces, giving them a reach of over 3000 kms and providing the country an effective deterrence capability.
"The sophisticated surface-to-surface missile is equipped with modern and compact avionics to provide high level of reliability," DRDO sources said.
The most accurate Ring Laser Gyro based Inertial Navigation System (RINS) and supported by highly reliable redundant Micro Navigation System (MINGS), ensures the vehicle reaches the target within two digit accuracy, they said.
The re-entry heat shield can withstand temperatures in the range of 4000 degree centigrade and makes sure the avionics function normally with inside temperature remaining less than 50 degree centigrade.
Ballistic missiles like Agni-I, II and III and Prithvi are already in the arsenal of armed forces, giving India an effective deterrence capability. Radars and electro-optical systems had been positioned along the coast of Odisha for tracking and monitoring all the parameters of the missile, the sources said, adding two Indian naval ships anchored near the target area to witness the final event.
The successful trial of Agni IV came close on the heels of a similar test on December 26, 2016 of long range missile Agni 5 which was successfully carried out from the same launch site.
‘Agni-5’, is capable of striking a target more than 5,000 km. It is about 17-metre long, 2-metre wide and has launch weight of around 50 tonnes. The missile can carry a nuclear warhead of more than one tonne.
Unlike other missiles of Agni series, the latest one 'Agni-5' is the most advanced having some new technologies incorporated with it in terms of navigation and guidance, warhead and engine.
