5Learning War examines the U.S. Navy's doctrinal development from 1898-1945 and explains why the Navy in that era was so successful as an organization at fostering innovation. A revolutionary study of one of history's greatest success stories, this book draws profoundly important conclusions that give new insight, not only into how the Navy succeeded in becoming the best naval force in the world, but also into how modern organizations can exploit today's rapid technological and social changes in their pursuit of success. Trent Hone argues that the Navy created a sophisticated learning system in the early years of the twentieth century that led to repeated innovations in the development of surface warfare tactics and doctrine. The conditions that allowed these innovations to emerge are analyzed through a consideration of the Navy as a complex adaptive system. Learning War is the first major work to apply this complex learning approach to military history. This approach permits a richer understanding of the mechanisms that enable human organizations to evolve, innovate, and learn, and it offers new insights into the history of the United States Navy.
