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.

The Joint Strike Fighter (JSF) program-a multinational acquisition program for the Air Force, Navy, Marine Corps, and eight cooperative international partners-is the Department of Defense's (DOD) most expensive aircraft acquisition program. DOD currently estimates it will spend $623 billion to develop, procure, and operate and support the JSF fleet. The JSF aircraft, which includes a variant design for each of the services, represents 90 percent of the remaining planned investment for DOD's major tactical aircraft programs. In fiscal year 2004, the JSF program was rebaselined to address technical challenges, cost increases, and schedule overruns. This report-the third mandated by Congess-describes the program's progress in meeting cost, schedule, and performance goals since rebaselining and identifies various challenges the program will likely face in meeting these goals in the future.
