Nuclear-capable ballistic missile Agni-IV was successfully test-fired from the Integrated Test Range No. 4 at the Dr Abdul Kalam Island off the sea coast around 8.30 am on Sunday.
The 4,000-km-range missile is equipped with state-of-the-art avionics, 5th-generation on board computer and distributed architecture. It has the latest features to correct and guide itself for in-flight disturbances.
It is 20 meter-long and weighs 17 tonnes. The two-stage Intermediate Range Ballistic Missile (IRBM) can take a nuclear warhead of one tonne.
The most accurate Ring Laser Gyro-based Inertial Navigation System (RINS) supported by a highly reliable redundant Micro Navigation System (MINGS) ensures the weapon to reach the target within two-digit accuracy.
Agni 1, 2, 3 and Prithvi are already in the arsenal of armed forces, giving them a reach of over 3,000 km, equipping India with an effective deterrence capability.
