Ballistic Missile Defence System Current Affairs
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.
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.
Indigenously developed supersonic Advance Area Defence (AAD) interceptor missile was successfully test-fired from launch complex III of the Integrated Test Range (ITR) at Abdul Kalam Island in Balasore, Odisha.
The supersonic interceptor missile is capable of destroying any incoming enemy ballistic missile at low altitude. The successful test validates the reliability of its two layered Ballistic Missile Defence (BMD) system.
Key Features of missile
- The AAD interceptor missile has been indigenously developed by DRDO. It is a 7.5-metre-long single stage solid rocket propelled guided missile.
- It is equipped with a navigation system, a hi-tech computer, inertial navigation system and an electro-mechanical activator.
- It can destroy the incoming hostile ballistic missile in the endo-atmospheric region (less than 30 km altitude) at a low altitude of less than 30 kms.
- It has its own mobile launcher, secure data link for interception, independent tracking and homing capabilities and sophisticated radars,
About India’s BMD programme
- The Research Centre Imarat (RCI) of the DRDO has played pivotal role in the development of all strategic missiles, spearheaded under the India’s double-layered ballistic missile defence (BMD) programme.
- The BMD consists of two interceptor missiles, Advanced Area Defence (AAD) missile for endo-atmosphere or lower altitudes and Prithvi Defence Vehicle for exo-atmospheric ranges.
- The DRDO expects deployment of BMD shield by 2022. India will be fourth country in the world after the US, Russia and Israel to successfully built effective anti-ballistic missile system.
- Earlier in February 2017, DRDO had successfully carried out test of the exo-atmospheric Pirthivi interceptor missile destroying the target outside the earth’s atmosphere at an altitude of over 85 km.
