India's DRDO has successfully tested the indigenously developed anti-radiation missile RudraM-II. The Rudram is a series of supersonic and hypersonic air-to-surface ground attack and anti-radiation missiles. An anti-radiation missile (ARM) is designed to detect and home in on an enemy radio emission source. Typically, these are designed for use against an enemy radar, although jammers and even radios used for communications can also be targeted in this manner.
