Key Takeaways:

The U.S. Air Force originated from the U.S. Army Signal Corps' Aeronautical Division, established on August 1, 1907, evolving through various predecessors like the Air Service and Air Corps.
During World War II, the Army Air Forces (AAF) experienced massive growth, expanding to over 63,000 aircraft and 2.25 million personnel, playing a critical role in strategic bombing and demonstrating the power of air warfare.
Recognizing its pivotal role and emergence as a "third independent service," the U.S. Air Force was formally established as a separate military branch on September 18, 1947, under the National Security Act.

Origins

Orville Wright made the world’s first controlled, powered, and sustained heavier-than-air human flight on December 17, 1903. Less than four years later (August 1, 1907), the U.S. Army Signal Corps formed an Aeronautical Division. It was put in “charge of all matters pertaining to military ballooning, air machines and all kindred subjects,” according to the Council on Foreign Relations. The division was the first heavier-than-air military aviation organization in history and the beginning of what eventually became the U.S. Air Force.
