Countries around the globe are continuously investing money into weapon development and manufacturing. While weapon design has been a relevant topic, from the Middle Ages to today, the morality of this practice is not commonly presented in research. The Morality of Weapons Design and Development: Emerging Research and Opportunities is an essential scholarly resource that presents detailed discussions on ethical dilemmas in weapons design and innovations. While highlighting relevant topics including projectile and nuclear weapons, the true costs of war, design in peacetime, and weapons development and justification, this book is an ideal resource for researchers, engineers, graduate students, and professionals who have an interest in weapons design, development, and ethics.
