His bio on wiki states, "Momyer returned to the United States in 1944 and became chief of the combined operations of the Army Air Forces Board. As a member, he played a significant role in the development of Air Force doctrine for air-ground operations."
Any idea if that would have been a one star billet?
I hit a dead-end on that. Momyer was pretty controversial, though, because of run-ins with the Tuskegee fliers and Chuck Yeager. Plenty about that online.
