Prithvi-II, Supersonic Interceptor & Barak-8 Missiles Successfully Test-Fired
Dec 04, 2015

Supersonic Interceptor Missile: On November 22, (DRDO) tested an indigenously developed supersonic interceptor missile—the Advanced Air Defence (AAD) missile. The AAD is part of the first phase of India’s Ballistic Missile Defense (BMD) initiative, along with the Prithvi Air Defence (PAD) missile.

  • The Prithvi provides exoatmosphermic defense while the AAD is optimized for endoatmospheric performance.

  • The test was conducted to validate various parameters of the interceptor in flight mode.

  • The test was conducted at a testing site on Abdul Kalam Island, which was formerly known as Wheeler Island.

  • The AAD has been undergoing trials since 2007 and may ultimately serve as a project demonstrator.

  • A full-scale BMD system in India will incorporate technology from both the PAD and AAD systems.

  • The AAD interceptor is a 7.5 meter single-stage, solid fuel rocket, capable of Mach 4.5 supersonic flight.

  • The AAD has an operational range between 150-200 kilometers and uses an inertial navigational aid system with active radar homing.

  • So far, it has been test-launched from a Transporter Erector Launcher (TEL).

  • As a short-range, ground-launched system capable of surface-to-air strikes against aircraft and unmanned aerial vehicles, the AAD will see some overlap with the more advanced Russian-made S-400 Triumph anti-ballistic missile system.

India’s development of a BMD system was identified as one area of possible cooperation with the United States in 2012. After the United States, Russia, and Israel, India is the fourth state to indigenously develop a BMD system.

On November 26, India successfully test-fired its indigenously developed nuclear capable Prithvi-II missile, which has a strike range of 350 km, as part of a user trial by the army. The missile was randomly chosen from the production stock and the entire launch activities were carried out by the specially formed SFC and monitored by the scientists of Defence Research and Development Organisation (DRDO) as part of training exercise

  • The missile test was carried out from a mobile launcher from launch complex-3 of the Integrated Test Range (ITR) at Chandipur.

  • The missile trajectory was tracked by DRDO radars, electro-optical tracking systems and telemetry stations located along the coast of Odisha.

  • The downrange teams on board a ship deployed near the designated impact point in the Bay of Bengal monitored the terminal events and splashdown. 

  • The surface-to-surface Prithvi-II missile is capable of carrying 500 kg to 1,000 kg of warheads and is thrusted by liquid propulsion twine engines. 

  • It uses advanced inertial guidance system with manoeuvring trajectory to hit its target.

  • Inducted into India's armed forces in 2003, Prithvi II, the first missile to be developed by DRDO under India's prestigious IGMDP (Integrated Guided Missile Development Program) is now a proven technology.

  • The last user trial of Prithvi-II was successfully conducted on February 19, 2015 from the same test range in Odisha. 

Such training launches clearly indicate India's operational readiness to meet any eventuality and also establishes the reliability of this deterrent component of the country's strategic arsenal.

  • Barak 8: Naval Barak-8 is a long-range surface-to-air missile jointly developed by Israel and India. On November 25, The Israel Navy performed its first sea-based operational intercept of the Barak-8 air defence system, one in a series of planned tests prior to planned initial operational capability within two years.

  • Barak-8 was launched from a Sa’ar-5 Covette against a UAV simulating a threat to a ship at sea.

  • Barak-8 successfully intercepted the target.

  • The system’s radar allowed the Navy to detect targets at long detection ranges, and the system enabled us to engage the threat from long-distance range.

  • The system’s digital phased array radar successfully acquired and tracked the target at a range of more than 20 kilometers but less than 120 kilometers.

  • The Barak-8 knows how to intercept from zero to 70 kilometers; so if the range of interception is a few kilometers, the scenario will take seconds. But if it’s at longer ranges, it can take less than two minutes.

  • Bharat Dynamics Limited (BDL) will be assigned the task of producing the missiles with 32 initial ones to be fitted on INS Kolkata.

The missile is being jointly developed by the Defence Research & Development Organisation (DRDO), Israel Aerospace Industries (IAI), Israel’s Administration for the Development of Weapons and Technological Infrastructure, Elta Systems, Rafael and other companies.
