The subject of this book, the first in chronological sequence of a series on nuclear weapons and international security, was aided by the release of archival material following the cold war. State secrecy is a powerful undercurrent, and the title evokes the contrast between what could be called political and technological perspectives on nuclear weapons that grew out of the requirement for secrecy. The focus is on the technological development of British nuclear weapons and the impact of United Kingdom, United States, and NATO policy on them. Its time frame is bracketed by the UK-U.S.A. cooperation agreement concerning mutual nuclear defense, signed in 1958, and the election of the Harold Wilson Labour government in 1964 after thirteen years of Conservative rule. Richard Moore argues that this period was crucial in defining Britain's defense policy for the following half-century. [End Page 722] Between the end of the Second World War and 1958, the United Kingdom had followed a lonely course, denied nuclear collaboration with the United States by its Atomic Energy Act and related security concerns. During that period, Britain had developed its own uranium and plutonium devices akin to the Hiroshima and Nagasaki weapons, amassed some fifty hand-built bombs, tested a single successful thermonuclear device, and had begun (barely) to configure the command and control infrastructure to support them. In this environment, posturing and rhetoric by politicians— who claimed the existence of a substantial deterrent and rational policy— conflicted with military reality. Over the subsequent six years, Moore suggests, the illusory aspects were amplified: some argued that Britain's nuclear strength was neither independent, wholly British, nor a genuine deterrent. Indeed, as observed by Solly Zuckerman, chief scientific advisor of the Ministry of Defense, deterrence was a political construct. This account focuses on two aspects of this story. The first concerns the political efforts to construct a credible defense policy, and the diplomatic interactions with the United States and NATO that eventually made it possible. The second aspect is policy execution, focusing on the development of nuclear technologies: the generation of fissile material for bombs, designs of nuclear warheads, delivery systems, and, just as important, the organization of the operating procedures that went with them. This split narrative mirrors the title, with the imagined political futures only loosely connected to the contemporary technological world. This linkage, perhaps the most interesting aspect for many readers of Technology and Culture, is usefully explored. About a dozen photographs illustrate a sprinkling of British nuclear weapons, military commanders, and politicians, but this is a text-driven book full of information. We learn, for example, that Britain had produced some 2,500 kg of weapons-grade plutonium and some 7,600 kg of enriched uranium—the latter used in reactor research and submarine propulsion as well as bombs—by 1964. The United States and United Kingdom also bartered comparable quantities of fissile material to overcome shortages for particular weapons. British weapons programs included Blue Danube (its first atomic bomb), Red Beard (a tactical nuclear weapon), the canceled Blue Streak and Skybolt guided missiles, and Yellow Sun megaton weapons. The technological systems, involving explosive devices, delivery vehicles, military tactics, and perennially scarce fissile material, evolved together awkwardly. The yield-to-weight ratio was critical, for example, as was the range and accuracy of missiles and bomber aircraft and their tactical deployment during war. The transnational connections are a newly revealed component of this story. Particularly interesting is the account of how warheads of American design were "anglicized" and produced in the United Kingdom to fill the gaps in this far-from-stable system. The wide-ranging sharing of information [End Page 723] via the various Anglo-American Joint Working Groups involved computer codes, fabrication technologies, radiochemistry, high-speed cameras, metallurgy, neutron sources, and numerous other subjects. Overall, this book illuminates an important period of UK policymaking and policy execution, revealing details, mechanisms, and motivations that once...
