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

Development

The AGM-122 Sidearm was produced by the re-manufacture of AIM-9C missiles that 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. Conceived and developed at China Lake NAWS, the Sidearm was first tested in 1981. In 1984, Motorola was issued a contract to convert and upgrade AIM-9Cs to the 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 anti-radiation missiles, such as 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. 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 against short-range radar guided anti-aircraft artillery and shorter range SAMs, including those fired by vehicles. The missile was capable of tracking a target even if it was moving.

The AIM-120 Advanced Medium-Range Air-to-Air Missile(AMRAAM) ( AM-ram) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the brevity code "Fox Three".

The AGM-88 HARM is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments.

The AGM-114 Hellfire is an American air-to-surface missile (ASM) first developed for anti-armor use, later developed for precision drone strikes against other target types, especially high-value targets. It was originally developed under the name "Heliborne laser, fire-and-forget missile", which led to the colloquial name "Hellfire" ultimately becoming the missile's formal name. It has a multi-mission, multi-target precision-strike ability and can be launched from multiple air, sea, and ground platforms, including the MQ-1 Predator and MQ-9 Reaper. The Hellfire missile is the primary 100-pound (45 kg) class air-to-ground precision weapon for the armed forces of the United States and many other nations. It has also been fielded on surface platforms in the surface-to-surface and surface-to-air roles.

ALARM is a British anti-radiation missile designed primarily to destroy enemy radars for the purpose of Suppression of Enemy Air Defenses (SEAD). It was used by the RAF and is still used by the Royal Saudi Air Force. The weapon was retired by the UK at the end of 2013.

<span class="mw-page-title-main">Air-to-air missile</span> Missile fired from the air at airborne targets

An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope.

Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target. Semi-active missile systems use bistatic continuous-wave radar.

<span class="mw-page-title-main">AGM-45 Shrike</span> Air-to-surface anti-radiation missile

AGM-45 Shrike is an American anti-radiation missile designed to home in on hostile anti-aircraft radar. The Shrike was developed by the Naval Weapons Center at China Lake in 1963 by mating a seeker head to the rocket body of an AIM-7 Sparrow. It was phased out by U.S. in 1992 and at an unknown time by the Israeli Air Force, and has been superseded by the AGM-88 HARM missile. The Israel Defense Forces developed a version of the Shrike that could be ground-launched with a booster rocket, and mounted it on an M4 Sherman chassis as the Kilshon.

The AGM-78 Standard ARM was an anti-radiation missile developed by General Dynamics, United States. It was built on the airframe of the RIM-66 Standard surface-to-air missile, resulting in a very large weapon with considerable range, allowing it to attack targets as much as 50 miles (80 km) away.

Short range air defense (SHORAD) is a group of anti-aircraft weapons and tactics that have to do with defense against low-altitude air threats, primarily helicopters and low-flying aircraft such as the A-10 or Sukhoi Su-25. SHORAD and its complements, HIMAD and THAAD divide air defense of the battlespace into domes of responsibility based on altitude and defensive weapon ranges.

Fox is a brevity code used by NATO pilots to signal the simulated or actual release of an air-to-air munition or other combat function. Army aviation elements may use a different nomenclature, as the nature of helicopter-fired weapons is almost always air-to-surface. "Fox" is short for "foxtrot", the NATO phonetic designation for the letter "F", which is short for "fire". A fighter pilot announcing that a weapon has been fired is intended to help avoid friendly fire, alerting other pilots to avoid maneuvering into the path of the munition.

Red Hebe was a large active radar homing air-to-air missile developed by Vickers for the Royal Air Force's Operational Requirement F.155 interceptor aircraft. It was a development of the earlier Red Dean, which was not suitable for launch by the new supersonic aircraft. Before progressing much beyond advanced design studies, F.155 was cancelled in the aftermath of the 1957 Defence White Paper which moved Britain's attention from strategic bombers to ballistic missiles. With no other suitable platform, Red Hebe was cancelled as well.
