This is a partial list of original Air Service, United States Army "Aero Squadrons" before and during World War I. Units formed after 1 January 1919 are not listed.

Overview

In January 1918 a new numbering scheme for aero squadrons was set up. Numbers 1–399 would be for Aero Service Squadrons (AS). 400–599 Aero Construction Squadrons (ACS), 600–799 Aero Supply Squadrons and 800–1099 Aero Repair Squadrons. Non-notable support squadrons are not listed.

The numerical designation of school squadrons at the various flying fields in the United States was discontinued in July 1918, and replaced by letter designation. For example, the 2d Aero Squadron became Squadron A, Kelly Field. In November 1918, the personnel of the lettered squadrons of each flying field was merged into a single Flying School Detachment at such station.

	Formed prior to 2 April 1917
	American Expeditionary Force combat squadron
	Planned American Expeditionary Force combat squadron (never entered combat)
	Currently active as United States Air Force/Air National Guard squadron
