The AGM-122 Sidearm is an anti-radiation missile designed to be used to attack radar installations and other ground-based electronic systems that emit electromagnetic radiation. The missile's guidance system is based on a passive homing seeker that can detect the radar signals emitted by the target and guide the missile to impact it.

The Sidearm was derived from the AIM-9 Sidewinder air-to-air missile, using its airframe, and propulsion system. However, the Sidewinder's infrared seeker was replaced with a passive radar homing seeker that enabled the Sidearm to home in on ground-based radar signals instead of heat signatures emitted by airborne targets.

The Sidearm was developed as a more cost-effective alternative to the AGM-45 Shrike missile. The Sidearm is smaller and lighter than the Shrike, making it more suitable for use by smaller aircraft such as the Harrier.
