American seapower requires a robust constellation of bases to support global power projection. Given the rise of China and the emergence of the Asia-Pacific as the center of global economic growth and strategic contention, nowhere is American basing access more important than in this region. Yet manifold political and military challenges, stemming not least of which from rapidly-improving Chinese long-range precision strike capabilities, complicate the future of American access and security here. This book addresses what will be needed to maintain the fundaments of U.S. seapower and force projection in the Asia-Pacific, and where the key trend lines are headed in that regard. This book demonstrates that U.S. Asia-Pacific basing and access is increasingly vital, yet increasingly vulnerable. It demands far more attention than the limited coverage it has received to date, and cannot be taken for granted. More must be done to preserve capabilities and access upon which American and allied security and prosperity depend.
