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.

World War I 1914–1918 global war originating in Europe

World War I, also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as "the war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. It is also one of the deadliest conflicts in history, with an estimated nine million combatants and seven million civilian deaths as a direct result of the war, while resulting genocides and the 1918 influenza pandemic caused another 50 to 100 million deaths worldwide.

Aero Squadrons were the designation of the first United States Army aviation units until the end of World War I. These units consisted of combat flying, training, ground support, construction and other components of the Air Service. After World War I ended, the majority of these squadrons were demobilized. Some however were retained during the interwar period of the 1920s and 1930s, and served in all theaters of operation during World War II. Today, the oldest squadrons in the United States Air Force and Air National Guard can trace their lineage back to the original Aero Squadrons of World War I.

United States Army Land warfare branch of the United States Armed Forces

The United States Army (USA) is the land warfare service branch of the United States Armed Forces. It is one of the seven uniformed services of the United States, and is designated as the Army of the United States in the United States Constitution. As the oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed to fight the American Revolutionary War (1775–1783)—before the United States of America was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.

World War II 1939–1945 global war

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

United States Air Force Air and space warfare branch of the United States Armed Forces

The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, and one of the seven American uniformed services. Initially formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U.S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947. It is the youngest branch of the U.S. Armed Forces, and the fourth in order of precedence. The USAF is the largest and most technologically advanced air force in the world. The Air Force articulates its core missions as air and space superiority, global integrated intelligence, surveillance, and reconnaissance, rapid global mobility, global strike, and command and control.

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.

In addition to the Aero Squadrons, whose mission supported airplanes in one way or another, Air Service Spruce Squadrons have been noted and listed. A part of the Signal Corps, they were located in Oregon and Washington states. When the U.S. entered World War I, it was quickly discovered that the nation had no capacity to build warplanes in quantity. Spruce timber, vital to wing construction was in critically short supply. In 1918, the United States Army stepped in and took over the production of airplane spruce in the pacific northwest, with the Spruce Production Division organizing loggers and constructing a plant to process the wood, construct roads and railroads into the forests to access and cut the timber.

Spruce Production Division

The Spruce Production Division was a unit of the United States Army that was established in 1917 to produce high-quality Sitka spruce timber and other wood products needed to make aircraft for the United States' efforts in World War I. The division was part of the Army Signal Corps's Aviation Section. Its headquarters were in Portland, Oregon, and its main operations center was at Vancouver Barracks in Vancouver, Washington. Workers in the division were members of the Loyal Legion of Loggers and Lumbermen, a union specifically established to support the army's wood production operations.

Men in the Spruce Squadrons were part of the Signal Corps along with the Aero Squadrons, as the Signal Corps oversaw all Army aviation. About 50,000 soldiers were assigned to Spruce Squadrons, overseeing about 100,000 lumber workers, were assigned to small camps in the Pacific Northwest. Many of these men were itching to go "over there" and take part in combat, however, their labor and skills to produce spruce lumber were needed far more, in the forests of the Pacific Northwest to produce the materiel needed to build aircraft. The camps where the soldiers were located are listed on the individual squadron entry.

Squadrons

1st to 24th Aero Squadrons

At the time of the United States entry into World War I in April 1917, three Aero Squadrons had been formed. The 1st and 3d were in the United States, and the 2d was in the Philippines. The 6th, being destined for Hawaii and the 7th, destined for the Panama Canal Zone were organizing. The 4th and 5th, to be based in the continental United States had yet to receive personnel.

Aeronautical Division, U.S. Signal Corps

The Aeronautical Division, Signal Corps (1907–1914) was the first heavier-than-air military aviation organization in history and the progenitor of the United States Air Force. A component of the U.S. Army Signal Corps, the Aeronautical Division procured the first powered military aircraft in 1909, created schools to train its aviators, and initiated a rating system for pilot qualifications. It organized and deployed the first permanent American aviation unit, the 1st Aero Squadron, in 1913. The Aeronautical Division trained 51 officers and 2 enlisted men as pilots, and incurred 13 fatalities in air crashes. During this period, the Aeronautical Division had 29 factory-built aircraft in its inventory, built a 30th from spare parts, and leased a civilian airplane for a short period in 1911.

Aviation Section, U.S. Signal Corps

The Aviation Section, Signal Corps, was the aerial warfare service of the United States from 1914 to 1918, and a direct statutory ancestor of the United States Air Force. It absorbed and replaced the Aeronautical Division, Signal Corps, and conducted the activities of Army aviation until World War I, when its statutory responsibilities were suspended for the duration of the war. The Aviation Section organized the first squadrons of the aviation arm and conducted the first military operations by United States aviation on foreign soil.

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.
