U.S. Air Force Day

The United States Air Force was established on September 18, 1907 and every year on this date the nation celebrates U.S. Air Force Day to recognize the service and sacrifices of the brave men and women who serve in this important branch of the military. Let’s take a look at the history behind this commemoration as well as how the Air Force continues to impact America and the world.

U.S. Air Force Day

The Early Years of Military Aviation

In the early 1900s, military aviation was still in its infancy but aircraft were beginning to be used for reconnaissance, surveillance and bombing missions. On September 18, 1907 the U.S. Army Signal Corps established an Aeronautical Division with one officer and two enlisted men. This small group was the origin of what would eventually become the U.S. Air Force.

Balloons and Early Airplanes

Initially, the focus was on ballooning for observation but powered flight capabilities were also being explored. Some of the earliest aircraft acquired for evaluation included designs from the Wright Brothers. Through World War I, aviation technologies advanced rapidly and aircraft took on increasingly important roles in combat. After the war, General Billy Mitchell emerged as a leading advocate for recognizing air power as a distinct form of warfare.

The Interwar Years

In the 1920s, the Aeronautical Division was renamed the Air Service but it remained subordinate to the Army. This period saw further experimentation and development of bombers, fighters, and other military aircraft. The Air Corps Act of 1926 granted aviation forces within the Army equal status with other combat arms but it was not yet a fully independent service. However, the seeds were being planted for what would eventually become a separation from the Army.

World War II Proved the Value of Air Power

When World War II engulfed Europe and the Pacific, American air forces demonstrated their critical importance. Bombing campaigns facilitated the defeat of Axis powers while air superiority missions supported ground forces. Iconic planes like the P-51 Mustang, B-17 Flying Fortress and P-38 Lightning helped achieve victory.

The Need for Independence

General Henry “Hap” Arnold emerged as a champion for an autonomous Air Force. He oversaw tremendous expansion and played a pivotal role in major engagements. The overwhelming success of strategic bombing added momentum to calls for independence from Army control.

The Air Force is Born

On September 18, 1947, the U.S. Air Force was established as an independent military branch under the National Security Act. This marked the culmination of decades of advancement for American military aviation and recognition that air power had come into its own as a dominant force in modern warfare.

Securing Freedom from Above

In the post-WWII era and Cold War, the newly minted U.S. Air Force took on responsibilities around the globe. Nuclear deterrence missions and cutting edge aerospace technologies positioned America as the dominant air and space power.

Korean War
Vietnam War
Gulf War and Beyond

From providing close air support and conducting strategic bombing campaigns to space exploration and homeland defense, the Air Force proved vital to national security time and again. Though military aviation has continued to evolve greatly, the core mission of securing America’s freedom from above remains unchanged.
