The Division of Military Aeronautics was the name of the aviation organization of the United States Army for a four-day period during World War I. It was created by a reorganization by the War Department of the Aviation Section, U.S. Signal Corps on April 24, 1918, still as part of the Signal Corps. It was removed from the Aviation Section by executive order on May 20, 1918, and existed as the sole Army aviation agency until a War Department general order issued May 24, 1918, established it and the Bureau of Aircraft Production, created by the same reorganization on April 24, as coordinate components of the "Air Service". As such, it is recognized by the United States Air Force as the third of its antecedents.
