War II progressed, the number of required pilot trainees declined, and the Army Air Forces decided not to send more aircrew trainees to Maxwell Field. The following known sub-bases and auxiliaries were constructed to support the flying school: Passmore Auxiliary Field Troy Auxiliary Field Autaugaville Auxiliary Field On 31 July 1943, the Southeast Air Corps Training Center was redesignated as the Eastern Flying Training Command. Also in July, the Army Air Forces announced a specialized school for pilots of four-engine aircraft. The first B-24 Liberator landed at the field later that month and in early 1945, B-29 Superfortress bomber training replaced the B-24 program. Cold War Training at Maxwell continued until 15 December 1945, when the Eastern Flying Training Command was inactivated and was consolidated into the Central Flying Training Command at Randolph Field, Texas. Air University, an institution providing continuing military education for Army Air Forces personnel, was established at Maxwell in 1946, prior to the U.S. Air Force becoming an independent service the following year. Today, it remains the main focus of base activities at Maxwell. Maxwell Field was renamed Maxwell Air Force Base in September 1947 when the Air Force was created. In 1992, the 3800th Air Base Wing (3800 ABW) was disbanded and the 502d Air Base Wing (502 BW) took over as the host wing, which two years later gave way to the current 42d Air Base Wing. As home of the Air University, Maxwell became the postgraduate academic center of the U.S. Air Force. Air University evolved first as an institution influenced by air power as shaped in World War II, then by the Cold War under the threat of nuclear annihilation, and by air power as applied during the Cold War's Korean and Vietnam conflicts. In the early twenty-first century, the emphasis shifted to air power's role in confronting international and transnational terrorism by both state-sponsored and non-state actors. AU grew materially from inadequate quarters, classrooms, and instructional technology into a campus that is as modern and up-to-date as those of any other in the U. S. armed forces. Construction of Maxwell's Academic Circle, Air University's primary education complex, began in the 1950s. Its centerpiece was the Air University Library, eventually one of several major libraries on a military installation. Over the years, other activities were established or relocated to Maxwell AFB, to include Headquarters, Civil Air Patrol – USAF; the Air Force
