When Was the US Air Force Founded?

The United States Air Force, one of the most advanced and respected military branches in the world, has a fascinating history. But when was the US Air Force founded, and how did it evolve into the force we know today? This blog dives into its origins, its milestones, and the legacy it carries today for those who serve and those who admire its rich history.

By the end of this blog post, you'll have a clear understanding of how, why and when was the Air Force founded and the pivotal role it has played in shaping the United States' military might.

The Birth of the US Air Force

The U.S. Air Force traces its roots back to World War I, a time when military aviation was still a budding concept. However, the official establishment of the modern Air Force as its own branch occurred decades later. While the use of aviation in the military began during the early 20th century, the Air Force was formally established on September 18, 1947 as a result of the National Security Act of 1947. When was the Air Force founded? Officially, it was in 1947, but as mentioned, the establishment of a separate airpower branch was decades in the making as the Air Force started as the Army Air Corps and Army Air Forces.

However, the National Security Act of 1947 reorganized the military’s structure after World War II, creating the Department of Defense and separating the Air Force from the Army. Until that time, the predecessors of the Air Force functioned as part of the U.S. Army, most notably under the banner of the Army Air Forces during World War II.

Why 1947?

The creation of the Air Force as a separate branch reflected the growing importance of aerial warfare. The experiences of World War II had proven that control of the skies could decisively impact the outcome of conflicts. Innovations in aircraft technology and strategies during the war underscored the need for an independent force focused exclusively on airpower.

Leaders like General Henry H. Arnold, widely regarded as one of the fathers of the modern Air Force, strongly advocated for a dedicated branch that could harness the full potential of aviation to protect and defend American interests. When was the Air Force founded? We’ve answered that, but let’s dive into what led to the creation of the US Air Force.

Evolution of Military Aviation Before 1947

The path to the founding of the Air Force was far from linear. Here's a quick look at the key developments leading up to its establishment:

The Early Years

1907 - The fledgling aviation division of the U.S. Army Signal Corps began operations, marking the Army's initial foray into military aviation.

1914 - The 1st Aero Squadron was formed, signaling the Army’s recognition of the strategic role airpower could play. That unit later became the 1st Reconnaissance Squadron and it is the U.S. military's oldest flying unit. The squadron has maintained unbroken lineage for more than a century from its founding. Originally organized to provide security along the border between the United States and Mexico, Gen. John J. Pershing directed the 1st Aero Squadron to become the first tactical aviation unit to participate in American military action. The 1st has flown 47 different aircraft models while being deployed worldwide at 52 locations, including 4 stints at sea.

Since 1922, the 1st Squadron has been associated with the 9th Bomb Group and the 9th Reconnaissance Wing where it continues to be an active flying training unit operating the U-2 spy plane and the RQ-4 Global Hawk surveillance aircraft.

World War I - Military aviation saw its first meaningful use. Though relatively primitive by today's standards, planes were used for reconnaissance, dogfighting, and limited bombing runs. All of these developments were key in when was the Air Force founded.

Between the Wars

The interwar years were marked by significant growth in aircraft technology and operational strategy:

1926 - The Army Air Corps was established, replacing the Air Service. This marked a step toward independence, though it still operated under the Army.

1930s - Visionary leaders such as Billy Mitchell lobbied for the importance of airpower, often at great personal and professional cost. Mitchell’s controversial demonstrations of airpower included sinking warships to prove that aircraft could dominate naval operations.

According to a U.S. Army news article, Mitchell was the first aviator to cross enemy lines in combat in WWI. After World War I, Mitchell returned to the U.S. and despite his achievements was reverted back to his permanent rank of colonel, due to Air Service drawdown in manpower. These facts are important because some of Mitchell’s drive was fueled by events in his career and those events would impact when was the Air Force founded.

He also learned he was not to be appointed to head the Army Air Service. Instead, Mitchell was selected as deputy chief. Despite his disappointment, Mitchell still advocated for an independent Air Force, and promoted the small Army Air Service with border patrols, forest fire patrols, aerial mapping missions and any other activity that demonstrated the value of aviation.

Mitchell became increasingly vocal in his opinion about the need to strengthen airpower. He publicly attacked superiors in the Army, Navy and even the White House, making a statement to the New York Times, Dec. 6, 1919 that read: "The United States had produced practically no aerial war equipment since the armistice and consequently, is not capable of meeting any first-class power in the air today, as foreign countries had continued development of wartime equipment."

He testified before the House subcommittee, where he told Congress that the Air Service could sink any battleship in existence. He called for a demonstration in which airplanes would bomb ships. Mitchell asked for a test to confirm that airplanes could bomb ships.

Congress and the Navy reluctantly gave in and on July 20 and 21, 1921, Mitchell and the 1st Provisional Air Brigade demonstrated to the world the superiority of air power. He and his unit sank the famous, "unsinkable," Ostfriesland, a captured German battleship.

However, the Navy was not pleased with the outcome of the tests; countering that Mitchell cheated by exceeding the parameter of the tests. Nonetheless, the Navy began developing aircraft carriers, while Congress continued to cut the Air Service's budget. The question, when was the Air Force founded wasn’t even on anyone’s mind.

Mitchell's frustration climaxed after the Navy's airship Shenandoah crashed due to weather in September 1925. Mitchell publicly accused the Navy and War Departments of "incompetence and criminal negligence." In a statement to the press, he said, "Brave airmen are being sent to their deaths by armchair admirals who don't care about air safety." That published statement was the beginning of the end of Mitchell's military career.

In November 1925, Mitchell was called to Washington D.C. and court-martialed on the charge of "Conduct to the prejudice of good order and military discipline and in a way to bring discredit upon the military service." Mitchell was convicted of insubordination, but rather than serve a five-year suspension, Mitchell decided to resign his commission.

During retirement in Virginia, he continued to be outspoken on the importance of air power. He wrote books, newspaper and magazine articles, and gave lecture tours until his death, Feb. 11, 1936. Mitchell eventually received several honors following his death including a posthumous promotion to major general by President Harry Truman.

World War II and the Birth of the Army Air Forces (AAF)

The outbreak of World War II further demonstrated the enormous potential of airpower:

The AAF grew exponentially, becoming one of the largest military air forces in history by 1945.

Operations like strategic bombing campaigns over Europe and the use of B-29 bombers in the Pacific were pivotal to the Allied victory.

The advances in jet engines, long-range bomber capabilities, and radar paved the way for post-war military aviation.

The AAF’s success cemented the idea that air dominance was a distinct and vital component of modern warfare.

The Formation of the Modern Air Force

By 1947, the National Security Act officially separated the Army Air Forces into its own distinct service. The establishment of the Air Force signified a strategic shift in how military branches operated, reflecting a broader, more technologically advanced approach to national security.

The first Secretary of the Air Force, Stuart Symington, was appointed to lead this new branch. The Air Force's new mission was clear:

• To control and exploit the air for military operations.
• To provide strategic defense and offense.

This autonomy allowed the Air Force to fully focus on technological innovation and strategy, laying the groundwork for operations that would go beyond Earth’s atmosphere in the future.
