Book excerpt: This book analyzes the development and evolution of the F-35 Joint Strike Fighter, a multinational aircraft endeavor involving the U.S. and many of its allies. The author provides a historical overview of jet fighter aircraft, discussing the different generations of these planes and their technical characteristics, as well as an outline of emerging international geopolitical and security trends the F-35 may see combat in. By examining the role of defense industries, domestic politics, and governmental oversight of the Joint Strike Fighter in various countries, the author concludes that this aircraft will be deployed in most of these countries to replace their aging jet fighter fleets and combat potential military aggression from China, Russia, and other revisionist international powers.
