    The PDV (Prithvi Defence Vehicle) tested on Tuesday is set to replace the Prithvi Air Defence (PAD) in India’s multi-layered ballistic missile defense program that currently comprises two components-the PAD for high altitude interception and Advanced Air Defense (AAD) Missile for lower altitude interception.

    The upgraded version of India's domestically-produced high-altitude interceptor missile PDV is now closer to being declared fully fit, as it successfully killed a simulated target from a defence facility off the cost of Odisha on Tuesday. The PDV is designed to destroy missiles at exo-atmospheric altitudes of 50-150 kilometres and be fired from a range of around 2,000 kilometres.

    The interceptor is guided by a high-accuracy Inertial Navigation System (INS) and supported by a Redundant Micro Navigation System (RMNS) which moves towards the estimated point of the interception.

    After the missile crosses the atmosphere, the heat shield is ejected and the infrared (IR) seeker dome opens to look at the target location as designated by the mission computer. With the help of inertial guidance and the IR seeker, the missile zeroes in on the target for interception. From detection to interception, the entire exercise is fully automated, with no need for human intervention, according to the DRDO.

    Interceptor missiles have been developed by DRDO (Defence Research and Development Organisation) as a strategic weapon against ballistic missile attacks. Successful trials of the endo interceptor missile (AAD) and exo interceptor missile (PDV) were also carried out in August 2018 and September 2018, respectively, according to a defence ministry release.
