From that small start grew the U.S. Air Force, one of the most powerful fighting forces in the world.
At first, military aviation was part of the U.S. Army. During World War I, pilots such as Captain Eddie Rickenbacker, who shot down 23 German planes over France, became national heroes. But few people foresaw the crucial role air power would play in future wars.
One who did was General Billy Mitchell, who urged the U.S. to create a strong air force. He was proved right during World War II, when the ability of the U.S. to control the air was a key factor in its victories.
In 1947, the U.S. Air Force became a separate branch of the U.S. armed forces. Since then, its pilots have performed expertly in Korea, Vietnam, the Persian Gulf, and wherever conflicts have arisen.
Also in 1947, the U.S. Air Force pilot Chuck Yeager, flying a rocket-powered X-1, became the first person to fly faster than the speed of sound.
Air Force men and women have placed key roles in the development of new aircraft and technology.
Today, about 500,000 people serve in the U.S. Air Force, which is divided into 12 commands, including the Strategic Air Command and the Tactical Air Command.
