Anant Shastra

The Anant Shastra, also known as Quick Reaction Surface-to-Air Missile (QRSAM), is a surface-to-air missile defense system developed by the Defence Research and Development Organisation, Bharat Electronics Limited, and Bharat Dynamics Limited for the Indian Army, meant for protecting moving armoured columns from aerial attacks. The system also forms a part of the Integrated Air Defence Weapon System (IADWS). The Command and Control System is completely automated. In addition to the launcher, the missile system has two four-walled radars that provide 360-degree coverage: the Active Array Battery Surveillance Radar and the Active Array Battery Multi-function Radar. An optical proximity fuze lessens the vulnerability to jamming.
