Joint Base San Antonio (JBSA) is a United States military facility located in San Antonio, Texas, USA. The facility is under the jurisdiction of the United States Air Force 502d Air Base Wing, Air Education and Training Command (AETC).

The facility is an amalgamation of the United States Army Fort Sam Houston, the United States Air Force Randolph Air Force Base and Lackland Air Force Base, which were merged on 1 October 2010.[1][2]


JBSA was established in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of the three facilities which were adjoining, but separate military installations, into a single Joint Base, one of 12 formed in the United States as a result of the law.

Joint Base San Antonio supports a population of 80,000 and supports students at three installations annually of up to 138,000. Upon becoming the largest single DoD installation/enterprise, it has a total Plant Replacement Value of about 10.3 billion, lead a work force of over 8,000 personnel, manages an annual budget of 800 million, interface with 1,000 civic leaders of San Antonio, 20 smaller communities, four counties and four Congressional Districts, support more than 200 mission partners, supported and supporting units, and finally, support more than 250,000 other personnel including 425 retired general officers (2nd largest concentration in U.S.).[2]

The post also supports the thousands of Army Reserve and National Guard soldiers who train there year round. Soldiers from Fort Sam Houston have participated in every American War since 1845 and have deployed worldwide in support of post-Cold War contingency operations.[2]

Together with Camp Stanley, Camp Bullis is part of the Leon Springs Military Reservation. Camp Bullis has provided firing ranges, training areas and logistics support to Fort Sam Houston and other active and reserve component units in South Texas for nearly 100 years. Its most frequent users are the Army Medical Department Center and School, Defense Medical Readiness Training Institute, Air Force Ground Combat Skills School and Army units stationed at Fort Sam Houston.

It serves as headquarters of the Air Education and Training Command (AETC) as well as the Air Force Personnel Center (AFPC) and is known as "the Showplace of the Air Force" because of the Spanish Colonial Revival Style architecture in which all structures including hangars were constructed. The symbol of the base is a large water tower atop Building 100, housing the headquarters for Randolph's major flying unit, the 12th Flying Training Wing (12 FTW). With its distinctive architecture, the wing's headquarters has come to be known throughout the Air Force as "the Taj Mahal," or simply "The Taj".[2]
