Prithvi Defence Vehicle Current Affairs - 2020

DRDO’s Igniter Complex inaugurated

A Defense Research Development Organization (DRDO) Igniter Complex was inaugurated at High Energy Materials Research Laboratory (HEMRL), Pune. The main purpose of the laboratory is to design, process, evaluate ignition systems for any kind of DRDO projects.

About the Igniter Complex

  • The new complex is equipped with sieve shaker, granulating machine, planetary mixer, pelleting machine, etc.
  • A design, modelling, simulation laboratory are a part of the complex.
  • The complex also has an assembly centre and a testing centre.


HEMRL develops rocket, pyrotechnic devices, gun propellants, high-explosive systems. Ignition is the crucial phenomenon in all these systems. HEMRL had developed ignition system for Prithvi, Agni, Nag, Akash, Pinaka, etc. It has also transferred the technology to Ordance factory, Pune. It also performs research on high-power explosives and on pyrotechnics.

A Brief History

In December 2015, a high-level committee that investigated a fire accident at the igniter complex had suggested this new complex. The committee found that there are grave risks to humans in making and designing of ignition systems and recommended advanced and remote controlled facility.

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.
