In 1962 Dean Acheson famously described Britain as having lost an Empire but not yet found a role. Perhaps nowhere is this more apparent than in the realms of nuclear weapons. An increasingly marginal world power, successive post-war British governments felt that an independent nuclear deterrent was essential if the country was to remain at the top table of world diplomacy. Focusing on a key twenty-year period, this study explores Britain's role in efforts to bring about a nuclear test ban treaty between 1954 and 1973. Taking a broadly chronological approach, it examines the nature of defence planning, the scientific goals that nuclear tests were designed to secure, Anglo-American relationships, the efficacy of British diplomacy and its contribution to arms control and disarmament. A key theme of the study is to show how the UK managed to balance the conflicting pressures created by its determination to remain a credible nuclear power whilst wanting to pursue disarmament objectives, and how these pressures shifted over the period in question. Based on a wealth of primary sources this book opens up the largely ignored subject of the impact of arms control on the UK nuclear weapons programme. Its appraisal of the relationship between the requirements and developments of the UK nuclear weapons programme against international and domestic pressures for a test ban treaty will be of interest to anyone studying post-war British defence and foreign policy, history of science, arms control, disarmament and non-proliferation and international relations. It also provides important background information on current events involving nuclear proliferation and disarmament.

Taking a broadly chronological approach, it examines the nature of defence planning, Anglo-American relationships, the efficacy of British diplomacy and UK contributions to arms control and disarmament. The appraisal of the relationship between the requirements and developments of the UK nuclear weapons programme against the countervailing international and domestic pressures for a test ban treaty will be of interest to anyone studying post-war British defence and foreign policy, history of science, arms control, disarmament and non-proliferation and international relations, or who is looking for background information on current events involving nuclear proliferation and disarmament.

This book provides an overview of how the UK tried to maintain and modernize its strategic and tactical nuclear weapons during 1974-82, whilst also pursuing a comprehensive nuclear test ban treaty. The core question addressed in the book is how a test ban treaty would impact on the reliability and safety of the UK’s nuclear weapons and how this would constrain and limit efforts to secure a comprehensive treaty that would prohibit nuclear testing indefinitely. An added complication lay in the fact that a ban treaty could also prevent or limit the UK’s ability to test new warhead designs to replace its existing tactical nuclear weapons and a new strategic successor system to Polaris. How all of this played out between 1974 and 1982, when the UK announced its decision to acquire Trident and the US decided that a test ban treaty was no longer in its security interests, is discussed. A detailed review, based on the available materials in the UK National Archives, also looks at the aims and objectives of UK nuclear tests in Nevada and on the decisions taken on the Chevaline warhead and its Trident replacement. The book also considers whether there was a far greater threat to the UK nuclear programme from shortages of skilled craftsmen and industrial action at the Atomic Weapons Establishment at Aldermaston than from a test ban treaty. It also looks at whether nuclear defence trumped arms control objectives during this period. This book will be of much interest to students of British politics, nuclear proliferation and Cold War History.

This document lists chronologically and alphabetically by name all nuclear tests and simultaneous detonations conducted by the United States from July 1945 through September 1992. Two nuclear weapons that the United States exploded over Japan ending World War II are not listed. These detonations were not "tests" in the sense that they were conducted to prove that the weapon would work as designed (as was the first test near Alamogordo, New Mexico on July 16, 1945), or to advance nuclear weapon design, or to determine weapons effects, or to verify weapon safety as were the more than one thousand tests that have taken place since June 30,1946. The nuclear weapon (nicknamed "Little Boy") dropped August 6,1945 from a United States Army Air Force B-29 bomber (the Enola Gay) and detonated over Hiroshima, Japan had an energy yield equivalent to that of 15,000 tons of TNT. The nuclear weapon (virtually identical to "Fat Man") exploded in a similar fashion August 9, 1945 over Nagaski, Japan had a yield of 21,000 tons of TNT. Both detonations were intended to end World War II as quickly as possible. Data on United States tests were obtained from, and verified by, the U.S. Department of Energy's three weapons laboratories -- Los Alamos National Laboratory, Los Alamos, New Mexico; Lawrence Livermore National Laboratory, Livermore, California; and Sandia National Laboratories, Albuquerque, New Mexico; and the Defense Threat Reduction Agency. Additionally, data were obtained from public announcements issued by the U.S. Atomic Energy Commission and its successors, the U.S. Energy Research and Development Administration, and the U.S. Department of Energy, respectively.

Surveillance is a key notion for understanding power and control in the modern world, but it has been curiously neglected by historians of science and technology. Using the overarching concept of the "surveillance imperative," this collection of essays offers a new window on the evolution of the environmental sciences during and after the Cold War.

Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons.
