• Sommario/riassunto: The Asia-Pacific region has emerged as the hub of global geo-political, geo-economic and geo-strategic significance in the post-Cold War period. The rise of China and the resurgence of India will be the hallmark for the next 50 years. How this surge in power is accommodated by the incumbent powers like the United States and Japan, and how the new regional powers like China and India manage the power politics that emerge will be the key determinants of regional stability. This volume examines the national maritime doctrines as well as the nuclear weapons developments at sea of the four major powers in the Asia-Pacific, namely, China, India, Japan and the United States, to see if the evolving dynamic is a cooperative or a competitive one. In particular, the volume looks at the evolving paradigms of maritime transformation in strategy and technology; the emergent new maritime doctrines and evolving force postures in the naval orders of battle; the role and operations of nuclear navies in the Asia-Pacific; and the implications and impact of nuclear weapons, ballistic missiles and sea-based missile defence responses in the region.
