This was an area where politi- cal and technical issues were intertwined, and understanding required knowledge and expertise of both. Archival material was sparse and most writings on the subject were based on information provided to well-placed journalists and confidential interviews with some of those involved. The result was that for the academic analyst, separat- ing truth from fiction was a very difficult task, especially in the case in the United Kingdom. With the end of the Cold War, archival material became available from all of the five declared nuclear-weapon states on their activities and scholars were able to discuss the previous century’s nuclear reality. A small community of scholars and former practitioners in the UK therefore started to rethink this history by producing a new series of volumes on the evolution of the United Kingdom’s nuclear weapon policies from 1952 onwards, the date of the explosion of its first nuclear device. Thanks to a grant from the UK Arts and Humanities Research Board to the Mountbatten Centre for International Studies at the University of Southampton, Professor John Simpson and his colleagues were able to start a systematic study of the post-1952 period, and to engage with those directly involved in its many aspects. What soon became clear was that in the period between 1958 and 1964 the course was set for UK nuclear policy in the next half-century. It is thus appropriate that Richard Moore’s volume Nuclear Illusion, Nuclear Reality: Britain, the United States and Nuclear Weapons, 1958–1964 should be the first of the planned chronological volumes arising from this systematic process. This is reinforced by the current salience of debates over the future of the UK’s nuclear deterrent force, and the role of the volume as the lead publication in Palgrave Macmillan’s wider series of studies on nuclear history.

This revealed that it progressed through a number of phases in its handling of these issues. Until 1958 the focus was on developing first generation nuclear and thermonuclear warheads and their delivery systems. From 1958 to 1964, as chronicled in Richard Moore’s companion volume Nuclear Illusion, Nuclear Reality, the focus was the weaponisation of second- generation nuclear devices to create a technically credible strategic deterrent force. This was assisted by US decisions to start nuclear exchanges with the UK and export advanced strategic delivery systems, including Polaris sub- marine based missiles. The current volume moves the story forward from 1964 to 1970. It describes the successive challenges during this period to the UK remaining a nuclear weapon state, including economic crises, political opposition and technical uncertainty and risks. The incoming Labour government led by Harold Wilson was constrained by national economic weakness. Difficult decisions had to be taken over the UK’s future global and regional security commitments and capabilities. Also, some of Labour’s ministers were known to oppose the UK’s continued possession of nuclear weapons. Wilson halted nuclear weapons testing and the development of new warhead designs, but a major programme to manufacture replacement third-generation strategic and tactical nuclear warheads moved ahead quietly. The UK’s conventional capabilities were overstretched in fulfilling new and existing European and extra-European defence commitments: conflicting calls on national defence resources reached crisis point in 1967. A number of drastic options were examined to reduce defence spending, including abandoning national nuclear weapon capabilities and terminating extra-European force deploy- ments, defence agreements and bases, including their stockpiles of nuclear weapons. The outcome was a decision to close all UK bases East of Suez by the early 1970s and withdraw all stockpiled nuclear weapons from them. In parallel, the UK was involved in debates over NATO strategy. The French withdrawal from NATO in 1966 facilitated a change in NATO doctrine from one of responding with ‘massive nuclear retaliation’ to an incursion by Warsaw Treaty forces to one of using a range of conventional or nuclear forces in a ‘flexible response’. One result was deployment of UK nuclear weapons to West Germany, giving the UK both a strategic and tacti- cal ‘second centre for nuclear decision’ capability in this event. Another was an apparent attempt by Wilson to facilitate entry into the EEC by offering vii 99778800223300330000888800__0011__pprreexxvvii..iinndddd vviiii 22//1166//22001122 1122::4477::5555 PPMM viii Series Editor’s Introduction to discuss nuclear issues with France. The ‘Mildenhall Agreement’ between the UK and US, where each agreed to inform the other of such exchanges, may have resulted from this activity. The period 1964–70 was therefore spent grappling with the long-term consequences of the UK decision to acquire and deploy a national nuclear weapon capability. Sustaining its technical capabilities, and thus its nuclear relationship with the US, threatened open ended financial and resource commitments. The assignment of Polaris to NATO for strategic targeting purposes was a condition for this transfer, though orders for use continued to be routed through the UK national command structure. This also meant that the UK retained the capability for independent targeting and deploy- ment. Yet while the Polaris force appeared to offer the UK a relatively invul- nerable and cost-effective ‘minimum deterrent’, doubts were soon emerging about its ability to penetrate USSR missile defences. Thus although the UK nuclear deterrent stockpile was being renewed and the nuclear relationship with the US had been revived, their future survival was still not assured.

Nuclear history is a difficult subject area to work in, due in no small measure to the sensitive nature of the material under consideration; although, given its centrality to defence and foreign policy, it deserves significant attention. This work does not seek to explore the morality of nuclear weapons; in this I am entirely in accord with Lawrence Freedman who stated in the introduction to Britain and Nuclear Weapons, ‘The agnosticism of this study is partly a reflection of a determina- tion to provide a book of description and analysis rather than advocacy.’ It seeks to provide a holistic investigation into British nuclear weapons policy in all its aspects. It examines areas of policy ranging from the acquisi- tion and manufacture of fissile material to nuclear warhead design, weapons deployment, means of nuclear delivery as well as operational strategy and tactics at national, bilateral and multilateral levels. Such wide areas of policy depict the size and scale of the effort involved. My family deserve my thanks for supporting me throughout. My mother Anne Stoddart, my uncle John Stoddart, who, in recounting his experiences as a Royal Navy sailor in the late sixties and early seventies enthused me in his distinctive and humble way. Jennifer Stoddart too has been a source of strength to me, as have family members past and present. Two former teachers of mine, John Llewellyn Jones and Ian Rees, also deserve mention for enthusing me from an early age with their love of learning. Support and friendship was also forthcoming from Leigh Bennett, Lee and Sian Williams (and family), Jeremy Thomas, Dr James Lee, Dr Peter Fleming, Dr’s Mark and Huw Boulton, Linda, Philip and Simon Dyton and my aunt Phylis Ward. No endeavour of this nature could have been attempted alone. I must extend my thanks to all those who have contributed directly and indirectly to this research project, including the late and much missed Sir Michael Quinlan, Kate Pyne, the Atomic Weapons Establishment’s Technical Historian, the staff at The National Archives at Kew, Dr John Walker of the Foreign Office, Dave and Lesley Wright of the British Rocketry Oral History Project (BROHP) and participants at the BROHP/UK Space confer- ences and to John Coker (RN retd.) and the staff of the Museum of Naval Firepower, Gosport. Thanks are also due to Dr Bill Burr at the National Security Archives, based at George Washington University in Washington DC, who provided valuable documentary evidence from the US archives which allowed for a greater appreciation of the ‘special nuclear relationship’ between the United States and Great Britain.
