As the United States seeks ways to stretch its defense dollars, pursue the Global War on Terrorism, and meet other national-security challenges, it is highly likely that policymakers will increase their reliance on aircraft carriers, using them more often and in more situations than they have in the past, especially if the vessels have the additional capabilities to respond appropriately. The current and expected use of aircraft carriers led the United States Navy in fall 2004 to commission RAND to explore new and nontraditional ways that the United States might be able to employ aircraft carriers in pursuit of traditional and emerging military and homeland defense missions. Over six months, RAND created and convened two Concept Options Groups (COGs)-small groups of experienced military and civilian experts, defense analysts, and potential users who work together to identify promising ways to employ military might in nontraditional ways-to explore possible nontraditional roles for aircraft carriers. One COG explored and identified new ways that aircraft carriers could be used in combat operations; the second COG examined ways that the vessels could be used in noncombat, homeland security missions or to help the nation recover from terrorist attacks or natural disasters in U.S. territories. Among the combat recommendations to come from the COG insights are that abilities need to be enhanced to reconfigure carrier air wings; among noncombat recommendations are that the availability of nonready carriers to respond to unforeseen crises needs to be improved. This monograph summarizes the activities, findings, and recommendations of both carrier COGs. It should be of special interest to the Navy and to uniformed and civilian decisionmakers with responsibilities related to naval and carrier operations, maritime domain awareness, or homeland security.

Military intervention always has been and always will be an important part of foreign policy, a tool to further national interests and influence world events. Many scholars have tried to explain the intervention behavior of states in crises, conflicts, and wars. When and why do states intervene, and what are reasons for nonintervention? What conflicts and crises are more likely to call for intervention, and why? When is intervention successful? The explanations are manifold and include political, military, economic, social, environmental, domestic, and humanitarian factors. The theoretical literature covers a gamut of realist intentions, ranging from security, power, and national interests, as guides to state action; to emphasis on international trade and economics; and to domestic politics. Some argue for explanations based on idealistic aspirations, such as democracy and human rights. Many studies focus on a mix of different reasons. From this vast field, the author has selected international crises involving any form of U.S. activity in the years 1946-2006. Within these U.S. activities, the author distinguishes between crisis response with and without naval forces, as this study intends to advance the knowledge of the use of U.S. naval forces as a response to international crises and to contribute to a better understanding of when and how the U.S. Navy is deployed.

The U.S. Navy is currently designing the next generation aircraft carrier, the CVN 21. This class of carriers will use the same basic hull form as the current Nimitz class but will include a substantial redesign of the interior of the ship for improved weapons handling and stores management functions. It will also incorporate several new technologies including a new propulsion system and new aircraft launch and recovery systems. These improvements not only will increase the operational capability of the ship but also are anticipated to lower the ship's manpower requirements and maintenance costs. Under current force modernization plans, new ships of the CVN 21 class will be introduced every four or five years as the ships of the Nimitz class reach the end of their planned 50-year operational life. Under this strategy, Nimitz class carriers will be operating for over 50 more years and it will take decades to transform the aircraft carrier fleet to ships of the new class.On the basis of some preliminary calculations that appeared promising, RAND proposed to the Program Executive Office (PEO) for Aircraft Carriers an examination of a way to accelerate the transformation of the carrier force: replacing Nimitz-class carriers as they reach mid-life instead of refueling them. In this report we identify specific fleet management options for building new instead of refueling, and we evaluate their advantages and disadvantages. This report should be of interest to Navy and Office of Secretary of Defense planners examining fleet modernization options, especially those organizations addressing the costs of alternative force structure options.

The authors assess several one- and two-deployment cycles, assuming a deployment length of six months and a time-between-deployments length equal to twice the duration of the previous deployment. Among many findings, RAND concludes that shorter cycles can increase the forward presence of the carrier fleet and help level shipyard workloads. Longer, two-deployment cycles can increase forward presence, but may result in shipyard workload complications and deferred-work backlogs."--BOOK JACKET.

This book examines US naval strategy and the role of American seapower over three decades, from the late 20th century to the early 21st century. This study uses the concept of seapower as a framework to explain the military and political application of sea power and naval force for the United States of America. It addresses the context in which strategy, and in particular US naval strategy and naval power, evolves and how US naval strategy was developed and framed in the international and national security contexts. It explains what drove and what constrained US naval strategy and examines selected instances where American sea power was directed in support of US defense and security policy ends – and whether that could be tied to what a given strategy proposed. The work utilizes naval capstone documents in the framework of broader maritime conceptual and geopolitical thinking, and discusses whether these documents had lasting influences in the strategic mind-set, the force structure, and other areas of American sea power. Overall, this work provides a deeper understanding of the crafting of US naval strategy since the final decade of the Cold War, its contextual and structural framework setting, and its application. To that end, the work bridges the gap between the thinking of American naval officers and planners on the one hand and academic analyses of Navy strategy on the other hand. It also presents the trends in the use of naval force for foreign policy objectives and into strategy-making in the American policy context. This book will be of much interest to students of naval power, maritime strategy, US national security and international relations in general.

Japan has been one of the most important international sponsors of human security, yet the concept has hitherto not been considered relevant to the Japanese domestic context. This book applies the human security approach to the specific case of the earthquake, tsunami and nuclear accident that struck Japan on 11 March 2011, which has come to be known as Japan's ‘triple disaster’. This left more than 15,000 people dead and was the most expensive natural disaster in recorded history. The book identifies the many different forms of human insecurity that were produced or exacerbated within Japan by the triple disaster. Each chapter adds to the contemporary literature by identifying the vulnerability of Japanese social groups and communities, and examining how they collectively seek to prevent, respond to and recover from disaster. Emphasis is given to analysis of the more encouraging signs of human empowerment that have occurred. Contributors draw on a wide range of perspectives, from disciplines such as: disaster studies, environmental studies, gender studies, international relations, Japanese studies, philosophy and sociology. In considering this Japanese case study in detail, the book demonstrates to researchers, postgraduate students, policy makers and practitioners how the concept of human security can be practically applied at a policy level to the domestic affairs of developed countries, countering the tendency to regard human security as exclusively for developing states.
