AGM-122 Sidearm

The AGM-122 Sidearm was an American air-to-surface anti-radiation missile.

Development
The AGM-122 Sidearm was produced by the re-manufacture of AIM-9C missiles which had been taken out of service. The AIM-9C was a semi-active radar homing variant of the Sidewinder, developed for the US Navy's Vought F-8 Crusader, but used for only a limited period of time. The Sidearm was first tested in 1981. In 1984, Motorola was issued a contract to convert and upgrade AIM-9Cs to AGM-122A standard. A total of about 700 units were produced between 1986 and 1990.

Existing stocks of Sidearm have been depleted, and the missile is no longer in service. Proposals for new-build missiles, under the designation AGM-122B, have not been proceeded with to date.

The AGM-122 was less capable than newer antiradiation missiles like the AGM-88 HARM, but also substantially cheaper, and its lighter weight enabled it to be carried by combat helicopters as well as fighter aircraft and fighter bombers.
