Randolph Air Force Base, the “Showplace of the Air Force,” was dedicated June 20, 1930, as a flying training base and has continued this mission ever since. Randolph lies just northeast of San Antonio in Universal City.
In February 2010, Randolph Air Force Base's host unit changed from the 12th Flying Training Wing to the 902d Mission Support Group. The change marked a transition to Joint Base San Antonio, when the 902d MSG became part of the 502d Air Base Wing at Fort Sam Houston, Texas.
The 902d Mission Support Group serves as the host unit for Randolph AFB and reports to the 502d Air Base Wing at Fort Sam Houston, Texas. The base has many tenant organizations, such as the Air Force Personnel Center, Air Force Recruiting Service Headquarters, 12th Flying Training Wing and Air Force Manpower Agency.
The base employs more than 5,000 military personnel and 4,600 civilian employees. Randolph is the site for the headquarters of the U.S. Air Force’s Air Education and Training Command, one of the Air Force’s major commands, as well as for the 19th Air Force.
