In what year did Hap Arnold become the first General of the Air Force?

Hap Arnold became the first General of the Air Force in 1947. This historic event was significant as it marked the elevation of the U.S. Air Force as a distinct branch within the military, separate from the Army. Arnold, who had previously served as a General in the Army Air Forces during World War II, was instrumental in advocating for the Air Force’s independence and modernization. The date of his promotion to General of the Air Force was March 7, 1947, coinciding with the official establishment of the independent United States Air Force on September 18 of that same year.
