Randolph Air Force Base was a United States Air Force base located at Universal City, Texas ( east-northeast of Downtown San Antonio). Opened in 1931, Randolph has been a flying training facility for the United States Army Air Corps, the United States Army Air Forces, and the Air Force during its entire existence. On 1 October 2010, Randolph AFB merged with Lackland Air Force Base and the US Army's Fort Sam Houston to form Joint Base San Antonio. Naming Randolph AFB was named after Captain William Millican Randolph, a native of Austin, who was on the base naming committee at the time of his death in a crash. The base served as headquarters of the Air Education and Training Command (AETC) as well as the Air Force Personnel Center (AFPC) and was 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 was 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 became known throughout the Air Force as "the Taj Mahal," or simply "The Taj".

One of the new general officer positions was given to Frank P. Lahm, who was placed in charge of all flying training. General Lahm established the Air Corps Training Center in August 1926 and set up its headquarters at Duncan Field, next to Kelly Field, Texas. He soon learned that the facilities at Kelly and Brooks Fields were not sufficient for proper training. The buildings, erected during World War I with a life expectancy of five years, had no suitable areas for ground training, and the living quarters were inadequate. San Antonio's rapid growth was also beginning to interfere with flying training operations. Maj. Gen. Mason Patrick, Chief of the Air Corps, visited San Antonio in December and recommended that an additional training field be built, and in April 1927 a board of officers appointed by Gen. Lahm approved an
