The U.S. Army Air Corps was the aerial warfare service of the United States Army from 1926 until 1941. It was responsible for organizing and training air units, as well as conducting air operations during its existence. The Air Corps played a crucial role in developing military aviation and laid the groundwork for future air power. In 1941, the Air Corps was reorganized into the United States Army Air Forces (USAAF) as a response to the growing importance of air power in modern warfare. This transition marked a significant shift in military strategy, emphasizing the need for a dedicated air service within the U.S. military.
