AGM-63 ARM (Anti-Radiation Missile)
The AGM-63 was a missile design developed in response to a March 1962 U.S. Navy requirement for new long-range ARMs (Anti-Radiation Missiles) to supplement the short-range AGM-45 Shrike. The ARM I was to have an effective range of 50 nm (90 km), while the ARM II would be capable of operating out to 100 nm (180 km). Development of the ARM I began in 1963, and it was given the designation ZAGM-63A. However, the name was about all it was given, as no funding was made available. Other ARM programs (initially the improvement of the AGM-45 Shrike, and then the development of the AGM-78 Standard ARM and AGM-88 HARM) had higher priority.
The U. S. armed services must suppress enemy air defenses to be able to accomplish their war fighting objectives and survive. To achieve this suppression, the services use specialized aircraft designed to neutralize, destroy, or temporarily degrade enemy air defense systems through either physical attack or electronic warfare. Specialized aircraft use electronic warfare devices, called jammers, to temporarily suppress enemy air defenses by transmitting electronic signals that disrupt enemy radar and communications. Other specialized aircraft use anti- radiation missiles that home in on radar used by surface- to- air missile or anti- aircraft artillery systems to physically degrade or destroy them. Because suppression aircraft are charged with protecting all of the services' aviation assets in hostile airspace, the suppression mission necessarily crosses individual service lines.
Combined arms tactics, techniques, and procedures (TTP) can enhance the effectiveness of combat arms attacks against the enemy and therefore reduce or nullify his ability to conduct aviation-related operations. Examples of combined arms include artillery fire to suppress antiaircraft defenses while attack aircraft deliver ordnance to destroy the target or electronic attack to suppress the enemy's ability to detect aircraft while other aircraft employ antiradiation missiles against the target. If the enemy attempts to power through the jamming, he provides a stronger signal for the anti-radiation missile. If he continues to radiate in an attempt to acquire targets, he remains vulnerable to electronic attack.
The AGM-63 continued for several years as a paper project. No design or configuration was ever settled on, and the project was cancelled in the late 1960s.
