Agni 5 Missile Test Fired off Odisha Coast

India successfully test fired its indigenously developed Agni- 5 missile on 3rd June. The missile was launched from Dr Abdul Kalam Island off the Odisha coast. Agni missile is a surface to surface missile and is launched with the help of mobile launcher of the Integrated Test Range at Dr Abdul Kalam Island formerly known as Wheeler Island. This is the 6th test fire of the state-of-the-art Agni 5 missile.

The trial was a great success. The missile hit its target with great accuracy after covering its full distance. The entire flight was monitored by radars, tracking instruments and observation stations.

Key Facts: Agni-5 Missile

Agni 5 ballistic missile is the brainchild of Defence Research and Development Organisation (DRDO). It is the most advanced in the series.

  • Agni-5 is a nuclear capable long range missile with new technologies in terms of navigation and guidance, warhead and engine. The three stage, 17- meter tall, two-meter wide Agni-5 missile has a range of Agni-5 missile is 5000 km. It can carry a nuclear warhead weighing up to 1.5 tonnes.
  • Agni-5 uses Ring Laser Gyro based Inertial Navigation System RINS. It is the most modern and gives very high accuracy. The Micro Navigation System or MINS helped the missile reach its target with precision.
  • Other features of Agni- 5 missile include, a high speed on- board computer, fault tolerant software and a robust reliable bus. The advanced computer and the inertial navigation system are the highlights of the missile as they aid in precision of the path.

The missile is highly reliable, has longer shelf life and enhanced mobility compared to the other versions. Agni-1 has a range of 700 km, Agni-2 with a 2000 km range, Agni-3 and 4 have a range of 2500 km to 3500km.

Maiden test Next Generation SFDR Air to Air Missile successfully conducted

The Defence Research and Development Organisation (DRDO) successfully carried out maiden flight test new surface-to-air missile (yet to get formal name) powered by Solid Fuel Ducted Ramjet (SFDR) propulsion Technology. The test also successfully demonstrated technology of nozzle less booster for first time in the country.

About Test

SFDR’s technology demonstrator flight test was conducted from Launch Centre-III of Integrated Test Range at Chandipur, Odisha. The defensive missile flew in its intended trajectory at speed of Mach 3 (thrice the speed of sound) and met all mission objectives.

Significance

SFDR technology is jointly developed by India and Russia. It will help both India’s surface-to-air and air-to-air missiles to perform better and enhance their strike range, making them more lethal. With it, India can have fastest long-range missiles in two categories, providing full-fledged and multi-layered aerial protection from hostile attacks.  Its successful use in missiles will mark India’s entry into select club of nations that use next-generation missile technology against maneuvering targets, compromising effectiveness of conventional missiles.

Difference between SFDR and Conventional Missiles

SFDR is propulsion technology different than that of conventional solid fuelled or liquid fuelled missiles. Present lot of conventional missiles uses booster or sustainer configuration with solid or liquid propellants, which have limitations against maneuvering target. This is because terminal stage of conventional missiles cannot provide enough energy to maintain their speed in order to hit targets. SDFR technology removes this drawback by exceptionally enhancing endgame maneuverability of missile at terminal stage when its seeker is locked onto target.
