Only officer to hold five-star rank in two US services.
Compare Henry Hap Arnold with another historical figure:
Arnold was appointed Commanding General of the US Army Air Forces, overseeing the expansion of the air force from 20,000 to 2.5 million personnel. He directed the strategic bombing campaigns in Europe and the Pacific.
Arnold was promoted to five-star rank as General of the Army, and later became the only officer to hold five-star rank in two US services when he was also made General of the Air Force. This recognized his role in creating an independent air force.
Arnold championed the development and production of the B-29 Superfortress, the most advanced bomber of World War II. The B-29 was used for strategic bombing of Japan and ultimately dropped the atomic bombs.
Arnold was a key advocate for the creation of an independent US Air Force, separate from the Army. The National Security Act of 1947 established the Air Force as a separate service, fulfilling Arnold's long-term goal.
