Tibbets then attended the Air Command and Staff School at Maxwell Air Force Base, Alabama. On graduating in 1947 he was posted to the Directorate of Requirements at Air Force Headquarters at the Pentagon. When the head of the directorate, Brigadier General Thomas S. Power, was posted to London as air attaché, he was replaced by Brigadier General Carl Brandt. Brandt appointed Tibbets as director of Directorate of Requirements's Strategic Air Division, which was responsible for drawing up requirements for future bombers. Tibbets was convinced that the bombers of the future would be jet aircraft and thus became involved in the Boeing B-47 Stratojet program. He subsequently served as B-47 project officer at Boeing in Wichita from July 1950 until February 1952. He then became commander of the Proof Test Division at Eglin Air Force Base in Valparaiso, Florida, where flight testing of the B-47 was conducted.
