Improvised explosive devices (IEDs) are a type of unconventional explosive weapon that can be deployed in a variety of ways, and can cause loss of life, injury, and property damage in both military and civilian environments. Terrorists, violent extremists, and criminals often choose IEDs because the ingredients, components, and instructions required to make IEDs are highly accessible. In many cases, precursor chemicals enable this criminal use of IEDs because they are used in the manufacture of homemade explosives (HMEs), which are often used as a component of IEDs. Many precursor chemicals are frequently used in industrial manufacturing and may be available as commercial products for personal use. Guides for making HMEs and instructions for constructing IEDs are widely available and can be easily found on the internet. Other countries restrict access to precursor chemicals in an effort to reduce the opportunity for HMEs to be used in IEDs. Although IED attacks have been less frequent in the United States than in other countries, IEDs remain a persistent domestic threat. Restricting access to precursor chemicals might contribute to reducing the threat of IED attacks and in turn prevent potentially devastating bombings, save lives, and reduce financial impacts. Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals prioritizes precursor chemicals that can be used to make HMEs and analyzes the movement of those chemicals through United States commercial supply chains and identifies potential vulnerabilities. This report examines current United States and international regulation of the chemicals, and compares the economic, security, and other tradeoffs among potential control strategies.

In response to the rising concern of the American public over illegal bombings, the Bureau of Alcohol, Tobacco, and Firearms asked the National Research Council to examine possible mechanisms for reducing this threat. The committee examined four approaches to reducing the bombing threat: addition of detection markers to explosives for pre-blast detection, addition of identification taggants to explosives for post-blast identification of bombers, possible means to render common explosive materials inert, and placing controls on explosives and their precursors. The book makes several recommendations to reduce the number of criminal bombings in this country.

This book comprises a national study of the explosives industry and provides a framework for identification of its industrial archaeology and social history. Few monuments of gunpowder manufacture survive in Britain from the Middle Ages, although its existence is documented. Late 17th-century water-powered works are identifiable but sparse. In the later 18th century, however, the industry was transformed by state acquisition of key factories, notably at Faversham and at Waltham Abbey.In the mid-19th century developments in Britain paralleled those in continental Europe and in America, namely a shift to production on an industrial scale related to advances in armaments technology. The urgency and large-scale demands of the two world wars brought state-directed or state-led solutions to explosives production in the 20th century. Yhe book’s concluding section looks at planning, preservation, conservation and presentation in relation to prospective future uses of these sites.

The noted historian offers “a compelling sociohistorical account of an often overlooked yet critical” WWII explosive twice as powerful as TNT (Choice). During the early years of World War II, American ships crossing the Atlantic were virtually defenseless against German U-boats. Bombs and torpedoes fitted with TNT barely dented the hulls of Axis naval vessels. Then, seemingly overnight, a top-secret manufacturing plant appeared near Kingsport, Tennessee, producing a sugar-white substance called Research Department Explosive, code name RDX. Twice as deadly as TNT and overshadowed only by the atomic bomb, RDX proved to be pivotal in the Battle of the Atlantic and directly contributed to the Allied victory in WWII. In The Secret History of RDX, Colin F. Baxter documents the journey of the super-explosive from conceptualization at Woolwich Arsenal in England to mass production at Holston Ordnance Works in east Tennessee. Baxter examines the debates between RDX advocates and their opponents and explores the use of the explosive in the bomber war over Germany, in the naval war in the Atlantic, and as a key element in the trigger device of the atomic bomb. Drawing on archival records and interviews with individuals who worked at the Kingsport “powder plant,” Baxter illuminates both the explosive’s military significance and its impact on the lives of ordinary Americans involved in the war industry. Much more than a technical account, this study assesses the social and economic impact of the military-industrial complex on small communities on the home front.
