Innovation shapes wars, and twelve studies by former faculty members of West Point’s United States Military Academy examine specific cases of past and present military innovation. The complex, competitive, and dynamic environment that defines war drives combatants to seek solutions to potentially lethal problems. As some solutions prove effective, gain traction, and win emulation, they follow a path of innovation. The chapters address a broad array of innovations, including in weapon technology, strategy, research and development philosophy, organization of the military instrument, and leveraging maps for strategic goals. Geographically, the examples in this volume span four continents and the Mediterranean Sea, and chronologically they proceed from the twelfth century to the twenty first. Collectively, the studies point to the interconnected value of pursuing constructive solutions to challenges, networking interdisciplinary forms of knowledge, appropriately balancing expectations and capabilities, and understanding an innovation as a journey rather than as an episodic event.

In 1903 the Wright brothers' airplane travelled a couple of hundred yards. Today fleets of streamlined jets transport millions of people each day to cities worldwide. Between discovery and application, between invention and widespread use, there is a world of innovation, of tinkering, improvement and adaptation. This is the world David Mowery and Nathan Rosenberg map out in Paths of Innovation, a tour of the intersecting routes of technological change. Throughout their book, Mowery and Rosenberg demonstrate that the simultaneous emergence of new engineering and applied science disciplines in the universities, in tandem with growth in the Research and Development industry and scientific research, has been a primary factor in the rapid rate of technological change. Innovation and incentives to develop new, viable processes have led to the creation of new economic resources - which will determine the future of technological innovation and economic growth.

How and when do military innovations take place? Do they proceed differently during times of peace and times of war? In Winning the Next War, Stephen Peter Rosen argues that armies and navies are not forever doomed to "fight the last war." Rather, they are able to respond to shifts in the international strategic situation. He also discusses the changing relationship between the civilian innovator and the military bureaucrat. In peacetime, Rosen finds, innovation has been the product of analysis and the politics of military promotion, in a process that has slowly but successfully built military capabilities critical to American military success. In wartime, by contrast, innovation has been constrained by the fog of war and the urgency of combat needs. Rosen draws his principal evidence from U.S. military policy between 1905 and 1960, though he also discusses the British army's experience with the battle tank during World War I.

The war instinct is part of human nature, but the means to fight war depend on technology. Alex Roland traces the co-evolution of technology and warfare from the Stone Age to the age of cyberwar, describing the inventions that changed the direction of warfare throughout history: from fortified walls, the chariot, battleships, and the gunpowder revolution to bombers, rockets, improvised explosive devices (IEDs), and nuclear weapons. In the twenty-first century, new technologies continue to push warfare in unexpected directions, while warfare stimulates stunning new technological advances. Yet even now, the newest and best technology cannot guarantee victory. Brimming with dramatic narratives of battles and deep insights into military psychology, this book shows that although military technologies keep changing at great speed, the principles and patterns behind them abide.

Waging War: Conflict, Culture, and Innovation in World History provides a wide-ranging examination of war in human history, from the beginning of the species until the current rise of the so-called Islamic State. Although it covers many societies throughout time, the book does not attempt to tell all stories from all places, nor does it try to narrate "important" conflicts. Instead, author Wayne E. Lee describes the emergence of military innovations and systems, examining how they were created and then how they moved or affected other societies. These innovations are central to most historical narratives, including the development of social complexity, the rise of the state, the role of the steppe horseman, the spread of gunpowder, the rise of the west, the bureaucratization of military institutions, the industrial revolution and the rise of firepower, strategic bombing and nuclear weapons, and the creation of "people's war."

The Diffusion of Military Power examines how the financial and organizational challenges of adopting new methods of fighting wars can influence the international balance of power. Michael Horowitz argues that a state or actor wishing to adopt a military innovation must possess both the financial resources to buy or build the technology and the internal organizational capacity to accommodate any necessary changes in recruiting, training, or operations. How countries react to new innovations--and to other actors that do or don't adopt them--has profound implications for the global order and the likelihood of war. Horowitz looks at some of the most important military innovations throughout history, including the advent of the all-big-gun steel battleship, the development of aircraft carriers and nuclear weapons, and the use of suicide terror by nonstate actors. He shows how expensive innovations can favor wealthier, more powerful countries, but also how those same states often stumble when facing organizationally complicated innovations. Innovations requiring major upheavals in doctrine and organization can disadvantage the wealthiest states due to their bureaucratic inflexibility and weight the balance of power toward smaller and more nimble actors, making conflict more likely. This book provides vital insights into military innovations and their impact on U.S. foreign policy, warfare, and the distribution of power in the international system.
