Since 1939, the U.S. government, using the National Defense Stockpile (NDS), has been stockpiling critical strategic materials for national defense. The economic and national security environments, however, have changed significantly from the time the NDS was created. Current threats are more varied, production and processing of key materials is more globally dispersed, the global competition for raw materials is increasing, the U.S. military is more dependent on civilian industry, and industry depends far more on just-in-time inventory control. To help determine the significance of these changes for the strategic materials stockpile, the Department of Defense asked the NRC to assess the continuing need for and value of the NDS. This report begins with the historical context of the NDS. It then presents a discussion of raw-materials and minerals supply, an examination of changing defense planning and materials needs, an analysis of modern tools used to manage materials supply chains, and an assessment of current operational practices of the NDS.

Lightweighting is a concept well known to structural designers and engineers in all applications areas, from laptops to bicycles to automobiles to buildings and airplanes. Reducing the weight of structures can provide many advantages, including increased energy efficiency, better design, improved usability, and better coupling with new, multifunctional features. While lightweighting is a challenge in commercial structures, the special demands of military vehicles for survivability, maneuverability and transportability significantly stress the already complex process. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft assesses the current state of lightweighting implementation in land, sea, and air vehicles and recommends ways to improve the use of lightweight materials and solutions. This book considers both lightweight materials and lightweight design; the availability of lightweight materials from domestic manufacturers; and the performance of lightweight materials and their manufacturing technologies. It also considers the "trade space"-that is, the effect that use of lightweight materials or technologies can have on the performance and function of all vehicle systems and components. This book also discusses manufacturing capabilities and affordable manufacturing technology to facilitate lightweighting. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft will be of interest to the military, manufacturers and designers of military equipment, and decision makers.

This new book from the National Research Council finds serious weaknesses in the government's plan for research on the potential health and environmental risks posed by nanomaterials, which are increasingly being used in consumer goods and industry. An effective national plan for identifying and managing potential risks is essential to the successful development and public acceptance of nanotechnology-enabled products. The book recommends a robust national strategic plan for addressing nanotechnology-related EHS risks, which will need to focus on promoting research that can assist all stakeholders, including federal agencies, in planning, controlling, and optimizing the use of engineered nanomaterials while minimizing EHS effects of concern to society. Such a plan will ensure the timely development of engineered nanoscale materials that will bring about great improvements in the nation's health, its environmental quality, its economy, and its security.

Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions. Research Progress on Environmental, Health, and Safety Aspects of Nanomaterials evaluates research progress and updates research priorities and resource estimates on the basis of results of studies and emerging trends in the nanotechnology industry. This report follows up the 2012 report A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which presented a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential environmental, health, and safety risks posed by ENMs. This new report looks at the state of nanotechnology research, examines market and regulatory conditions and their affect on research priorities, and considers the criteria for evaluating research progress on the environmental, health, and safety aspects of nanotechnology.

The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.

This nation‘s Cold War and Global War on Terror defense structures need an update. U.S. Naval Power in the 21st Century provides such a framework for the changed world we live in, offering a detailed roadmap that shows how the United States can field a war-winning fleet that can also compete aggressively in peacetime against dangerous competitors unlike any the nation has faced before. Brent Sadler presents a compelling new strategy and organizing approach that he calls naval statecraft, which acknowledges the centrality and importance of the maritime domain. While similar in scale and scope to Cold War containment strategies against the Soviets, naval statecraft is much more. It must be to challenge China‘s involvement in global supply chains, which gives that country significant financial heft and influence around the world. Unlike what existed during of the Cold War, however, Sadler provides a unique vision for competing with China and Russia. Rather than simply calling for better coordinated U.S. diplomacy, military operations, and economic statecraft, Sadler argues for integrating the levers of national power coherently and in a sustainable way. This is no small feat, and his approach is informed by a long career rich in working with various agencies of government, foreign militaries (including hostile ones), and our allies. It is an approach imminently appropriate to our times but comes with a realization that the nation is not ready for the competition it faces from China and Russia. The book is a valuable contribution to the national debate over how best to respond to China‘s rise and Russia‘s antagonisms.

Information is crucial when it comes to the management of resources. But what if knowledge is incomplete, or biased, or otherwise deficient? How did people define patterns of proper use in the absence of cognitive certainty? Discussing this challenge for a diverse set of resources from fish to rubber, these essays show that deficient knowledge is a far more pervasive challenge in resource history than conventional readings suggest. Furthermore, environmental ignorance does not inevitably shrink with the march of scientific progress: these essays suggest more of a dialectical relationship between knowledge and ignorance that has different shapes and trajectories. With its combination of empirical case studies and theoretical reflection, the essays make a significant contribution to the interdisciplinary debate on the production and resilience of ignorance. At the same time, this volume combines insights from different continents as well as the seas in between and thus sketches outlines of an emerging global resource history.

Our current production-consumption system extracts raw materials from the earth, creates tangible products and after one or two uses, disposes of them in landfills. Recycle Everything; Why We Must, How We Can provides evidence of declining availability of raw materials from respected journals and organizations including the Department of Defense. The book explains how materials can be recycled in a system that retains and reuses them perpetually. In addition to parts suppliers, producers, distributors and consumers, there are new roles: collectors, disassemblers, used-parts brokers and materials processors. These new roles make it possible to recover, reprocess and reuse materials. Products are no longer sold and their materials lost; they are leased and tracked on their entire journey around the system from producer to consumer and back to producer. Finally, the book briefly describes the Institute for Material Sustainability and its role in helping industries transform themselves from linear systems dependent on extraction to systems that are self-sufficient and sustainable indefinitely into the future.
