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 were 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.
