Nuclear Capable Agni-IV successfully test-fired

India has successfully test-fired nuclear-capable long-range ballistic missile Agni-IV from the Dr Abdul Kalam Island in Odhisa. It was the 7th trial of Agni-IV missile. DRDO had positioned Radars and electro-optical systems along the coast of Odisha for tracking and monitoring all parameters of the missile and two naval ships were anchored near the target area to witness the final event.

Agni IV

The strategic surface-to-surface missile has a strike range of 4,000 km. The indigenously developed Agni IV is a two-stage missile and is 20 meters long with a weight of 17 tonnes.

Agni IV is equipped with advanced Avionics, 5th generation On Board Computer and distributed architecture to provide a high level of reliability and precision.

Agni IV is also equipped with accurate Ring Laser Gyro based Inertial Navigation System (RINS) which is supported by highly reliable redundant Micro Navigation System (MINGS) to ensure the vehicle reaches the target with accuracy.

The re-entry heat shield of Agni IV can withstand temperatures in the range of 4000 degrees centigrade and also makes sure avionics function normally with the inside temperature remaining less than 50 degrees centigrade.

About Dr Abdul Kalam Island

Dr Abdul Kalam Island, formerly known as Wheeler Island, is an island off the coast of Odisha. The Island was originally named after English commandant Lieutenant Wheeler and it was renamed after the late Indian president, Dr APJ Abdul Kalam who is also referred as Missile Man of India on 4 September 2015.

Agni-5 missile successfully test-fired

Nuclear capable surface to surface Agni-5 ballistic missile was successfully test-fired from Dr Abdul Kalam Island off the Odisha coast. It was user associated trial of missile undertaken by strategic force command along with DRDO scientists.

About Test

The missile was launched with help of mobile launcher from launch pad-4 of the Integrated Test Range (ITR) at Dr Abdul Kalam Island in the Bay of Bengal. During this trial, the flight performance of the missile was tracked and monitored by radars, tracking instruments and observation stations.

It was seventh trial of the indigenously-developed surface-to-surface missile. The first test was conducted in April 2012, second in September 2013, third in January 2015 and fourth in December 2016. The fifth test was held January 2018 and seventh was held in June 2018. All the trials were successful.

 Agni-5 ballistic missile

It is three-stage solid propellant nuclear-capable intercontinental ballistic missile (ICBM), indigenously developed by the Defence Research and Development Organisation (DRDO). It is about 17 metres long, 2 metres wide and has a launch weight of around 50 tonnes.

Agni-5 is latest and most advanced variant in terms of navigation and guidance, warhead and engine in Agni series of missiles.  It has strike range of over 5,000 kilometres and can carry nuclear warhead of 1.5 tonne. Thus, it can hit most northern parts of China and other parts of Asia, Europe and Africa.

Unlike other missiles of Agni series, Agni-5 is most advanced missile having new technologies incorporated with it in terms of navigation and guidance, warhead and engine. It is also a fire and forget missile, which once fired cannot be stopped, except by interceptor missile which only US, Russia and Israel have.

It carries Multiple Independently Targetable Re-entry Vehicles (MIRV) payloads. A single MIRV equipped missile that can deliver multiple warheads at different targets. It is also incorporates advanced technologies involving ring laser gyroscope and accelerometer for navigation and guidance. It has not yet inducted into the Services.
