Army Air Defense Command, previously Army Anti-Aircraft Command, was a major command of the United States Army which existed from 1957 to 1974. The previous ARAACOM was created in 1950 and was redesignated ARADCOM in 1957. It was formed to command the Army units allocated to the air defense of the Continental United States. ARAACOM was also charged with becoming the Army component of a joint continental defense force, if and when the joint force was designated. On March 21, 1957, ARAACOM was renamed to U.S. Army Air Defense Command (USARADCOM). On 26 July 1960, ARADCOM activated a sixth region.
