The AGM-122 Sidearm was an American air-to-surface anti-radiation missile (ARM). The AGM-122 Sidearm was produced by the remanufacture of AIM-9C missiles which had been taken out of service. 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. The AGM-122 was less capable than newer ARMs 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.
