The United States Army Air Forces (USAAF) was the aerial warfare service of the United States during World War II. Established in 1941, it was a part of the United States Army and played a crucial role in various military operations, including strategic bombing campaigns in Europe and the Pacific. The USAAF was responsible for developing air power and coordinating air missions, which significantly contributed to the Allied victory. In 1947, the USAAF was reorganized and became the United States Air Force (USAF), an independent branch of the military. This transition marked a shift in focus towards air defense and the development of advanced aircraft and technology. The legacy of the USAAF continues to influence modern air operations and military strategy.
