Keesler continued to focus upon specialized training in Consolidated B-24 Liberator maintenance until mid-1944. Thereafter, the base expanded its curricula to train mechanics for other aircraft. By September 1944, the number of recruits had dropped, but the workload remained constant. Keesler personnel began processing veteran ground troops and combat crews who had returned from duty overseas for additional training and follow-on assignments. The number of men who went through basic training wound down markedly after the end of World War II, and it was discontinued at Keesler on 30 June 1946. In late May 1947, the Radar School was established at Keesler (transferred from Boca Raton Army Air Field), making it responsible for operating the two largest military technical schools in the United States. Thereafter, shrinking budgets forced the base to reduce its operating costs: the Airplane and Engine Mechanics School and the Radar School were consolidated on 1 April 1948. In early 1949, the Radio Operations School transferred to Keesler from Scott Air Force Base, Illinois. In addition to training radio operators, Keesler was to begin teaching air traffic service technicians; aircraft approach controllers, ground radar mechanics, and radar repairman/ground controlled approach specialists. The last mechanics training courses had moved to Sheppard Air Force Base, Texas, by November. In early 1956, Keesler entered the missile age by opening a ground support training program for the Atlas missile. In 1958, all control tower operator, radio maintenance, and general radio operator courses were put under Keesler's already broad technical training roof. During the early 1960s, Keesler lost many of its airborne training courses, but it remained the largest training base throughout the 1970s. This included limited flight training operations in the T-28 Trojan for Republic of Vietnam Air Force (VNAF) student pilots. Hurricane Camille produced considerable damage as it passed over Biloxi in 1969. Most of the Back Bay housing area was under water. Keesler's student load dropped to an all-time low after the Vietnam War ended. As a result, Air Training Command inactivated the USAF School of Applied Aerospace Sciences on 1 April 1977 and replaced it with the 3300th Technical Training Wing, which activated the same day. During the early 1980s Keesler's air traffic control program garnered publicity - when the Professional Air Traffic Controllers Organization walked off the job in August 1981. When President Ronald Reagan fired the strikers, Keesler-trained military air traffic controllers were used to direct some of the nation's air traffic.
