Origins Of The Nike System

Nike, named for the mythical Greek goddess of victory, was the name given to a program which ultimately produced the world's first successful, widely-deployed, guided surface-to-air missile system. Planning for Nike was begun during the last months of the Second World War when the U.S. Army realized that conventional anti-aircraft artillery would not be able to provide an adequate defense against the fast, high-flying and maneuverable jet aircraft which were being introduced into service, particularly by the Germans.

During 1945 Bell Telephone Laboratories produced the "AAGM (Anti Aircraft Guided Missile) Report" in which the concept of the Nike system was first outlined. The report envisioned a two-stage, supersonic missile which could be guided to its target by means of ground-based radar and computer systems. This type of system is known as a "command" guidance system. The main advantage over conventional anti-aircraft artillery was that the Nike missile could be continuously guided to intercept an aircraft, in spite of any evasive actions taken by its pilot. By contrast, the projectiles fired by conventional anti-aircraft artillery (such as 90mm and 120mm guns) followed a predetermined, ballistic trajectory which could not be altered after firing.

End Of The Nike Era

Although Nike was created in response to Soviet efforts to design and deploy long-range bomber aircraft during the early years of the Cold War, Soviet military strategy soon changed. By the late 1950s, fearing that their manned aircraft would be too vulnerable to attack by American interceptor aircraft armed with rockets and missiles, the Soviet Union focused more of its attention on developing ICBMs or Intercontinental Ballistic Missiles against which there existed, at that time, no effective defense. The Soviet long-range strategic bomber force continued to operate throughout the Cold War. However, these forces never achieved the size or capabilities of their American counterpart, the U.S. Air Force's Strategic Air Command or SAC.

The shifting nature of the Soviet threat meant that the air defense role, for which Nike was originally intended, became relatively less critical as time passed. Defense dollars were needed for other projects (including the development of American ICBMs and potential missile defenses) and also to fund the rapidly growing war in Vietnam. As a result, beginning in the mid 1960s, the total number of operational Nike bases within the continental U.S. was fairly steadily reduced, on an almost annual basis. All Nike Ajax sites in the continental United States were closed down by 1964. Closures of select Nike Hercules sites began during the mid 1960s.

During 1974, all remaining operational sites within the nationwide Nike air defense system were inactivated. Army Air Defense Command (ARADCOM) which administered this system was closed down shortly thereafter. The deactivation of the nationwide Nike missile system signaled the end of one of the nation's most significant, highly visible and costly Cold War air defense programs.
