The Nike Ajax was the world's first operational surface-to-air guided missile system. Its origins lay in the immediate post-war time, when the U.S. Army realized that guided missiles were the only way to provide air-defense against future fast high-flying bombers. Western Electric became prime contractor for the XSAM-G-7 Nike missile system, and Douglas as primary subcontractor was responsible for the missile airframe.
