India conducts successful Prithvi interceptor missile test at night

India successfully conducted interceptor missile test off the Odisha coast at night. With this, Defence Research and Development Organization achieved major milestone in developing indigenous two-layer Ballistic Missile Defence system.

About test

PDV interceptor missile was launched from Abdul Kalam Island (earlier known as Wheeler Island) of the Integrated Test Range (ITR) off Odisha coast. Its mission was aimed at test-firing of interceptor missile of coast of Odisha to intercept an incoming ballistic missile off the Bay of Bengal

During the test, both PDV interceptor and target missile were successfully engaged in automated operation. In this operation mode, the radar-based detection and tracking system of missile system detected and tracked target ballistic missile.

The computer network with help of data received from radars predicted trajectory of incoming ballistic missile. Based on this inputs PVD was fired for an interception and destroyed the incoming missile target with high accuracy.

Prithvi Defence Vehicle (PDV) missile

Prithvi Defence Vehicle (PDV) missile has been developed by indigenously by DRDO. It is two-stage missile and both stages are powered by solid propellants. It is intended to replace the existing Prithvi Air Defence (PAD) in PAD/Advanced Air Defence (AAD) combination.

It is designed for engaging targets in exo-atmosphere region at altitude 50 km of earth’s atmosphere. It is guided by high-accuracy Inertial Navigation System (INS) supported by Redundant Micro Navigation System for estimating point of interception.

Once missile crossed atmosphere, its heat shield ejected and IR Seeker dome is opened to look at target location as designated by mission computer. With help of Inertial Guidance and IR seeker, missile moves for interception. The missile is also fitted with Imaging Infrared (IIR) seeker, developed by DRDO, to distinguish between incoming warheads and decoys.

Prithvi supersonic interceptor missile successfully test fired

Indigenously developed Prithvi Advanced Air Defence (AAD) supersonic interceptor missile was successfully test-fired from a test range in Odisha. It is capable of destroying any incoming ballistic missile in low altitude.

Test

The target missile Prithvi interceptor AAD missile was launched from launch complex 3 of Integrated Test Range (ITR) at Chandipur in Odisha. After getting signals by tracking radars the missile directed its trajectory to destroy hostile target missile in mid-air in an endo-atmospheric altitude.

Prithvi AAD supersonic interceptor missile

The Prithvi interceptor is a 7.5-meter long single stage solid rocket propelled guided missile. It is equipped with a navigation system, a hi-tech computer and electro-mechanical activator. It can destroy the incoming hostile ballistic missile in endo-atmospheric region (less than 30 km altitude) at a low altitude of less than 30 kms. The state-of-the-art missile has its own mobile launcher, secure data link for interception, independent tracking and homing capabilities and sophisticated radars.

Comment

This was the third supersonic interceptor test of missile carried out this year in which an incoming ballistic missile target was successfully intercepted, within 30 km altitude of the earth’s atmosphere. The earlier two tests were conducted on February 11 and March 1 2017, as part of efforts to have full-fledged multi-layer Ballistic Missile Defence system.
