In April 1917, as the United States entered World War I, the Aviation Section of the U.S. Army Signal corps had only a handful of usable flying fields. This number quickly grew exceeding 40 by the end of the war. By the end of 1943, these fields had grown to an astounding peak of 783- 345 main bases, 116 subbases, and 322 auxiliary fields - a number not including the many depots and ranges. This manuscript details 89 bases in a statistical format, which their histories - a topic of particular interest both inside and outside the Air Force.
