United States Army Air Service

The United States Army Air Service was the military branch responsible for aviation operations from 1918 to 1926. It originated during World War I as the U.S. military's air division, focusing on reconnaissance, combat, and support roles using aircraft. It laid the groundwork for modern U.S. air forces, emphasizing technological development, pilot training, and strategic air capabilities. In 1926, it evolved into the United States Army Air Corps, which eventually became the independent U.S. Air Force in 1947. The Air Service played a crucial role in establishing military aviation's importance within national defense.
