In 1952, Sanders Associates, Inc., worked with McDonnell Aircraft Company to develop a radar using phased array concepts. This led to the PANoramic Array Radar (PANAR) contract with the U.S. Air Force. Its key design element—multibeam phased arrays—is the basis of present-day radar defense and surveillance systems.
The Air Force may wind up buying land to build 120 new intercontinental ballistic missile silos as part of its revamped infrastructure approach for the new Sentinel ICBM.
