The Organization of the U.S. Army Air Service in 1925 is a snapshot of that service from its final major organizational change in June 1924, when the 1st Wing (then a training establishment) was inactivated, to its name change in July 1926 to the Air Corps. Except for activation of a school group from the Regular Army's Inactive component for primary flying training at March Field, resulting in creation of the 24th School Wing, and reallocation of four existing tactical squadrons to new groups in 1927 and 1928, the organization of the Air Corps remained largely unchanged from this list until November 1930.
