Confronted with problems associated with the continual upgrading of field guns, reducing the number of different items in supply and lowering overall costs, the Department of the Army has need for improved methods of reducing erosion and extending the wear life of long range cannon. The National Materials Advisory Board was asked to consider all facets of this need and to make recommendations. Erosion in Large Gun Barrels assesses the nature of the bore erosion problem; identifies fruitful areas of research; assesses the state of technology of materials and methods in areas which may become significant to gun tubes of improved performance; and suggests experimental techniques, devices, and instruments and methods of reducing data to enhance the continuing coordination of the activities of the three Services.

One of Mashable's "17 books every activist should read in 2019" Join the conversation about creating a future with fewer guns and finally make a difference—this "smart, thoughtful, commonsense plan" (Donna Brazile) shows you how Ninety-six people die from guns in America every single day. Twelve thousand Americans are murdered each year. The United States has more mass shootings, gun suicides, and nonfatal gun injuries than any other industrialized country in the world. Gun-safety advocates have tried to solve these problems with incremental changes such as background checks and banning assault style military weapons. They have fallen short. In order to significantly and permanently reduce gun deaths the United States needs a bold new approach: a drastic reduction of the 390 million guns already in circulation and a new movement dedicated to a future with fewer guns. In Guns Down, Igor Volsky tells the story of how he took on the NRA just by using his Twitter account, describes how he found common ground with gun enthusiasts after spending two days shooting guns in the desert, and lays out a blueprint for how citizens can push their governments to reduce the number of guns in circulation and make firearms significantly harder to get. An aggressive licensing and registration initiative, federal and state buybacks of millions of guns, and tighter regulation of the gun industry, the gun lobby, and gun sellers will build safer communities for all. Volsky outlines a New Second Amendment Compact developed with policy experts from across the political spectrum, including bold reforms that have succeeded in reducing gun violence worldwide, and offers a road map for achieving transformative change to increase safety in our communities.

Advanced energetic materialsâ€"explosive fill and propellantsâ€"are a critical technology for national security. While several new promising concepts and formulations have emerged in recent years, the Department of Defense is concerned about the nation's ability to maintain and improve the knowledge base in this area. To assist in addressing these concerns, two offices within DOD asked the NRC to investigate and assess the scope and health of the U.S. R&D efforts in energetic materials. This report provides that assessment. It presents several findings about the current R&D effort and recommendations aimed at improving U.S. capabilities in developing new energetic materials technology. This study reviewed U.S. research and development in advanced energetics being conducted by DoD, the DoE national laboratories, industries, and academia, from a list provided by the sponsors. It also: (a) reviewed papers and technology assessments of non-U.S. work in advanced energetics, assessed important parameters, such as validity, viability, and the likelihood that each of these materials can be produced in quantity; (b) identified barriers to scale-up and production, and suggested technical approaches for addressing potential problems; and (c) suggested specific opportunities, strategies, and priorities for government sponsorship of technologies and manufacturing process development.
