The Army Air Forces (AAF) 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. The AAF was responsible for strategic bombing, air support for ground troops, and reconnaissance missions. In 1947, the AAF was reorganized into the United States Air Force (USAF), becoming an independent branch of the military. The transition marked a significant shift in U.S. military strategy, emphasizing the importance of air power in modern warfare. The AAF's legacy continues to influence air operations today.
