This document is a comprehensive historical study documenting the evolution of a premier military educational institution from the early years of post–World War I through 1940. It meticulously details the development and revisions of the curriculum, including specialized courses in attack aviation, bombardment, pursuit, observation, and related subjects outlined in Training Regulations 440-15, while describing critical administrative changes and the formation of key committees. The text records the internal workings of the Air Corps Board and Air Service Board, outlines significant shifts such as the introduction of short courses in 1939 and the eventual suspension of the regular nine-month course, and provides extensive appendices that include detailed faculty and staff rosters alongside a complete list of graduates by class with their ranks and branches. This study also examines the integration of doctrinal innovations into operational tactics, the coordination with infantry and other branches, and the institution's pivotal role in shaping strategic air power concepts prior to World War II.
