This talk will examine the UK’s decision to build a replacement for its current nuclear warhead. It explores the potential reasons for the decision, the choices that the UK is facing in its replacement warhead program, and the political, financial, technological and strategic implications of those choices. This includes consideration of the challenges of producing a new nuclear warhead in the post-CTBT era, the state of the UK’s nuclear weapons infrastructure, the UK’s cooperative relationships with the United States and with France, and the ways in which public scrutiny of the warhead program might be improved.
