United States Air Force (AIO) — 1,234 Aircraft Fleet

The United States Air Force (USAF) is the aerial warfare service branch of the U.S. Armed Forces, established in 1947 and headquartered at the Pentagon in Arlington, Virginia. Rather than a commercial airline, it operates a vast military transport and logistics network, including strategic airlift with large aircraft like the C-17 Globemaster III and C-5 Galaxy, as well as fighter jets, bombers, and specialized military aircraft. The USAF maintains a global presence through numerous bases across the United States and overseas, supporting military operations, humanitarian missions, and airlift of personnel and cargo worldwide. Its Air Mobility Command (AMC) handles long-range transport operations, while other commands manage combat operations, space operations, and cyberwarfare. The organization operates some of the world's most advanced military aircraft and is one of the largest operators of fixed-wing aircraft globally, serving as the backbone of U.S. military air power and defense strategy.
