What is an Anti-Radiation Missile (ARM)?

An anti-radiation missile is used to detect an enemy’s source of radio emission. These are mostly manufactured to be used against the enemy radar. Such missiles are 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.

The objective with which these missiles are designed is to break the enemy defence during the first leg of the battle so that the chances of surviving the further waves by the strike aircraft could be doubled.

Recent Update: In October 2020, the DRDO successfully tested indigenously manufactured RUDRAM, the new generation anti radiation missile (NGARM). RUDRAM is a long range, air launched missile.
