TheAGM-122 Sidearm was an Americanair-to-surfaceanti-radiation missile produced between 1986 and 1990. While not as capable as newer anti-radiation missiles, they were cheaper and lighter in weight allowing more versatile deployment.
The AGM-122 Sidearm was produced by the re-manufacture ofAIM-9C missiles that had been taken out of service. The AIM-9C was asemi-active radar homing variant of the Sidewinder, developed for theUS Navy'sVought F-8 Crusader, but used for only a limited period of time. Conceived and developed atChina Lake NAWS, the Sidearm was first tested in1981. In1984,Motorola was issued a contract to convert and upgrade AIM-9Cs to theAGM-122A standard. A total of about 700 units were produced between1986 and1990.
Existing stocks of Sidearm have been depleted, and the missile is no longer in service. Proposals for new-build missiles, under the designationAGM-122B, have not been proceeded with to date.
The AGM-122 was less capable than newer anti-radiation missiles, such as theAGM-88 HARM, but also substantially cheaper, and its lighter weight enabled it to be carried by combat helicopters as well asfighter aircraft andfighter bombers. The missile was primarily fielded aboard Marine Corps AH-1T/W Sea Cobra attack helicopters, and Marine Corps AV-8B Harrier jump jets, and could take the place of self-defense air to air missiles. The weapon retained the same warhead of the AIM-9C, which gave it a fairly limited destructive ability against armored vehicles. However, due to the nature of radiation homing missiles, the AGM-122 aimed for the radar emitter directly, all but guaranteeing the operational elimination of the target.
The Sidearm was primarily intended for use againstshort-range radar guided anti-aircraft artillery and shorter rangeSAMs, including those fired by vehicles. The missile was capable of tracking a target even if it was moving.
