The United States Army Air Corps (USAAC) was the aerial warfare service of the United States Army from 1926 until 1941. It played a crucial role in the development of military aviation and was responsible for training pilots and conducting air operations. The USAAC was instrumental in establishing air power as a vital component of modern warfare. In 1941, the USAAC was reorganized into the United States Army Air Forces (USAAF) as part of the larger military structure during World War II. This transition marked a significant expansion of air capabilities, leading to increased emphasis on strategic bombing and air support for ground forces.
