Scott Air Force Base is a United States Air Force base in St. Clair County, Illinois, near Belleville and O'Fallon, east-southeast of downtown St. Louis. Originally Scott Field, it was one of 32 Air Service training camps established after the United States entered World War I in April 1917.William R. Evinger: Directory of Military Bases in the U.S., Oryx Press, Phoenix, Ariz., 1991, p. 147. The present base serves as the headquarters of Air Mobility Command (AMC) and its showcase wing, and it is also the headquarters of the U.S. Transportation Command, a unified combatant command that coordinates transportation across all the services.

The base is operated by the 375th Air Mobility Wing (375 AMW) and is also home to the Air Force Reserve Command's 932d Airlift Wing (932 AW) and the Illinois Air National Guard's 126th Air Refueling Wing (126 ARW), the latter two units being operationally under AMC.

As of this date, the base employs 13,000 people, 5,100 civilians with 5,500 active-duty Air Force, and an additional 2,400 Air National Guard and Reserve personnel. The Air Force announced in June 2014 that two new cybersecurity squadrons will be added to the three currently on base.

Its airfield is also used by civilian aircraft, with civilian operations at the base referring to the facility as MidAmerica St. Louis Airport. MidAmerica has operated as a Joint Use Airport since beginning operations in November 1997.

History

World War I During World War I, Secretary of War Newton Baker advocated an expanded role for aviation. Business and political leaders on both sides of the Mississippi River wanted the Midwest to be chosen as a site for one of the new "flying fields." Aerial expert Albert Bond Lambert joined the St. Louis Chamber of Commerce and directors of the Greater Belleville Board of Trade to negotiate a lease agreement for nearly 624 acres of land.United States Air Force.

After inspecting several sites, the U.S. War Department agreed to the lease June 14, 1917. Congress appropriated $10 million for its construction, and 2,000 laborers and carpenters were immediately put to work. The layout of Scott Field was typical of aviation fields built during World War I. Construction began in June 1917. The government gave the Unit Construction Company 60 days to erect approximately 60 buildings, lay a mile-long railroad spur, and to level off an airfield with a 1,600 foot landing circle. Construction was underway when the government announced, on July 20, 1917, that it would name the new field after Corporal Frank S. Scott, the first enlisted service member killed in an aviation crash. Scott had died after an unexpected engine failure had brought down the aircraft that Lieutenant Lewis Rockwell had been giving him an orientation flight in at College Park, Maryland, on September 28, 1912.

Scott Field began as an aviation-training field for World War I pilots in August 1917 when the 11th and 21st Aero Squadrons from Kelly Field, Texas, arrived. Construction was completed in August, and the first flight from Scott Field occurred 2 September 1917. Flying instruction began 11 September 1917. Later the 85th and 86th Aero Squadrons arrived, and more than 300 pilots and many ground units were trained for service by the war's end in 1918.

Training units assigned to Scott Field were:Order of Battle of the United States Land Forces in the First World War, Volume 3, Part 3, Center of Military History, United States Army, 1949 (1988 Reprint) Post Headquarters, Scott Field – October 1919 114th Aero Squadron, February 1918 Re-designated as Squadron "A", July–November 1918 221st Aero Squadron, December 1917 Re-designated as Squadron "B", July–November 1918 242d Aero Squadron (II), April 1918 Re-designated as Squadron "C", July–November 1918 Squadron "D", July–November 1918 Flying School Detachment (Consolidation of Squadrons A–D), November 1918 – November 1919

By 2 September, William Couch, a civilian flying instructor, and Scott Field Commander, Major George E. A. Reinburg, made the first flight from Scott Field in a Standard J-1 two-seater biplane. At least seven J-1s were already on Scott; by the time the first Curtiss JN-4D "Jenny" arrived. Operable from the front or rear seat, the 8-cylinder, 90- horsepower, Jenny would become the primary trainer used on Scott Field. Everything moved fast in a wartime environment, including the dangerous act of learning to fly airplanes. A judgment error or weather shift could produce severe accidents in the fragile aircraft of the day, so it soon became apparent that Scott Field needed a medical air evacuation capability.

Determined to improve the recovery of Scott's downed pilots, Captains Charles Bayless (post surgeon), Early Hoag (officer-in-charge of flying) and A.J. Etheridge (post engineer), along with Second Lieutenant Seth Thomas, designed two air ambulances, or hospital planes—using a configuration likely modeled after one in use at Gerstner Field, Louisiana. By the summer of 1918, Scott Field's engineering department had completed the rear cockpit modifications needed to convert two Jennies. Not long thereafter, on 24 August 1918, as aviator with a broken leg became Scott's first air evacuated patient.

Also reassuring was the support Scott Field enjoyed from the local community. Plenty of curious sightseers came just to watch the construction or catch a glimpse of airplane activity, but many from the local community also gave morale support to their "Sammies" (Uncle Sam's boys). They hosted dances and receptions, established a library branch on the field, and invited soldiers into their homes for Thanksgiving dinners. Likewise, Scott Field hosted sporting events with their community neighbors. On 17 August 1918, they invited the public to attend a field meet and flight exhibition—Scott's first air show.

Flying was discontinued at Scott Field after the war and the base population dropped. The War Department purchased Scott Field in 1919 for $119, 285.84

Inter-War period

Scott Field's future became uncertain after the 11 November 1918 armistice with Germany and the end of World War I. Large scale demobilization closed many U.S. airfields. Scott's remaining units were organized into a Flying School Detachment, and the field itself was designated as a storage site for demobilized equipment. Welcome news came early in 1919, with the War Department's announcement of its decision to purchase Scott Field, a decision influenced by Scott's central location and exceptional purchase price of $119,285.84. This gave Scott a promise of a future; however, it still lacked a mission.

Scott was transformed into a lighter-than-air (LTA) station in 1921, with the transfer of the Army Balloon and Airship School from Brooks Field, Texas. Lighter-than-air ships were used at Scott Field to research the capabilities of aerial photography, meteorology and conduct altitude experiments. The most notable addition was the new airship hangar. Constructed between September 1921 and January 1923, it was three blocks long, nearly one block wide and 15 stories high. One report commented that 100,000 men—nearly the entire U.S. Army in 1923—could have stood in formation inside it. Scott's hangar was second in size only to the naval station hangar in Lakehurst, New Jersey, the largest one in the world at the time. The base also had hydrogen production facilities, which were enhanced significantly around 1923.

Consistent with the transformation of the facility, Major John A. Paegelow was selected as commanding officer of the facility in 1923, succeeding Colonel C. G. Hall who left the facility "to pursue a course of instruction in rigid airships with the Navy." Paegelow had been during World War I the commander of all Allied lighter-than-air activities on the warfront.

A couple of highlights of Scott's LTA era (1921–1937) include the 74-mph speed record for dirigibles, set by Scott Field's TC-1 in 1923, and the American free balloon altitude record of , set in 1927, by Captain Hawthorne C. Gray. Captain Gray would have set a world record later that same year had he survived that flight.

In the late 1920s, emphasis shifted from airships to balloons. In 1929, the 12th Airship Company was inactivated and replaced the next day by the 1st Balloon Company. Airplanes began to dominate activities at Scott Field by the mid-1930s. A series of airship mishaps led the Chief of the Army Air Corps to recommend an end to LTA activities in May 1937, and the following month Scott's LTA era came to an abrupt end.

Scott Field's central location was advantageous when it was considered for the relocation site of the General Headquarters Air Force (GHQAF), which managed the combat arm of the U.S. Army. Scott Field grew from 628 acres in 1938 to 1,882 acres in 1939. Most of the frame World War I and lighter-than-air constructions were torn down—only a few, such as the 9th Airstrip Squadron headquarters/barracks building, a brick theater and nine sets of brick non-commissioned officers' quarters at the south end of the field were saved.

New housing, industrial and administrative buildings were completed by May 1939. The expansion program continued into 1940 with the construction of 21 more buildings, including a 200-man barracks, a 300,000-gallon elevated water tank, a 43-bed hospital, Hangar No. 1 and a General Headquarters Air Force office.

Scott Field, as it existed at the end of the 1940 expansion program, is listed as the Scott Field Historic District on the National Register of Historic Places.

World War II

With the outbreak of World War II, the GHQAF move to Scott was cancelled. Instead, Scott Field reverted to its former role as a training installation. On 1 June 1939, one of Scott's Balloon Groups was redesignated as a headquarters unit of the Scott Field Branch of the Army Air Corps Technical Schools. Subsequently, various technical schools moved to Scott. Its communications training era began in September 1940 with the opening of the Radio School.

After September 1940, the primary wartime mission of Scott was to train skilled radio operator/maintainers; to produce, as the Radio School's slogan proclaimed, "the best damned radio operators in the world!" Scott's graduates flew in aircraft and operated command and control communications in every Theater of the War, and were often referred to as the "Eyes and Ears of the Army Air Forces." By the end of World War II, Scott's Radio School—becoming something of a "Communications University of the Army Air Forces", where it expanded during the war to fill about 46 large school buildings on base. It was from this course that many specialized radio and communications courses evolved, and had graduated 77,370 radio operator/mechanics. While all had been important to the nation's victory, two of the schools better known graduates were Medal of Honor recipient Technical Sergeant Forrest Lee Vosler, and the future first Chief Master Sergeant of the Air Force, Paul Airey.

Though the Radio School was the primary World War II-era mission, it was not intended to be Scott's only mission. The Air Corps had also planned for Scott to become a major air terminal due to its centralized location in the United States. In 1940, a $1 million project began to construct four mile-long concrete runways. Though not fully completed until November 1942, the portions that were complete provided a capability to give advanced flying school graduates instruction in instrument and night flying, navigation, photography, and administrative flights. By late 1943, the Radio School students were in the air as well, practicing code transmission under actual flight conditions. Unfortunately, airfield operations had to be sharply curtailed in May 1944, after an accidental tool-spark set fire to Hangar 1—Scott's only hangar. Repairs were not completed until May 1945.
