The ability of the United States Navy to fight and win a protracted war in the Pacific was not solely the result of technology, tactics, or leadership. Naval aviation maintenance played a major role in the U.S. victory over Japan in the second World War. In Sustaining the Carrier War, I show that America's naval war war against Japan did not achieve sustained success until enough aircraft technicians were available to support the high tempo of aviation operations that fast carrier task force doctrine demanded. This argument is a first for naval history and brings with it a new understanding of how US Naval Aviation helped America become one of the Great Powers in the modern age of Sea Power. It is not traditional "Battle History," but rather it is the history of the battle.
