UK Nuclear Deterrence Network

Evidence of the renewed salience of nuclear weapons is growing: the dawn of nuclear multipolarity, deepening integration of nuclear and non-nuclear capabilities, and evolving nuclear doctrines and capabilities across nuclear-weapons states. This resurgence of nuclear challenges on the global stage, coupled with developments in transatlantic and intra-European relations, requires a fresh assessment of the current state and future of nuclear deterrence for the UK and its allies.

The UK Nuclear Deterrence Network, a consortium comprising King’s College London, the RUSI and the University of Leicester, seeks to understand the practice and theory of deterrence, assess the value of deterrence against a changing international landscape, generate evidence-based research and recommendations, and develop a UK-based community of practice engaged with the role and future of deterrence for the UK and its allies.

The Network will offer innovative approaches to current nuclear deterrence challenges through two main pathways: providing intellectual contributions through research and publications and building a stronger knowledge base for early- and mid-career experts through the Deterrence Futures Fellowship.

This project aims to analyse and expand the landscape of ideas and thinking surrounding UK nuclear deterrence by engaging a range of perspectives and approaches to the current and future role of deterrence for the UK and further afield.

This will be achieved through a combination of research and knowledge generation which will provide intellectual contributions to the understanding of current nuclear deterrence challenges. The project will also include an international dimension to connect British and NATO allied communities of practice.<

The project seeks to generate fresh thinking across three areas concerning the changing circumstances facing the British nuclear deterrent and their consequences for UK nuclear policy:

1. Great power strategic competition
2. Navigating a landscape with multiple nuclear competitors
3. Updating strategic concepts and practices of deterrence

By inviting a diverse range of candidates to participate in the Deterrence Futures Fellowship, the UK Nuclear Deterrence Network also hopes to establish a more modern and holistic approach to deterrence while advancing innovation and improvements in UK policymaking.

The project is supported by the UK Ministry of Defence through its Nuclear Deterrence Fund.

The UK Nuclear Deterrence Network is a led and managed by a consortium of British institutions at the leading edge of nuclear policy studies in the UK: The University of Leicester, King’s College London, and the Royal United Services Institute

The UK Nuclear Deterrence Network is now seeking applications for its inaugural Deterrence Futures Fellowship, an 18-month cohort of early- and mid-career professionals seeking to learn about and engage with the concept of deterrence and its role in UK and international security.

Applications will open on 11 June and will be open until 23:59 BST on 2 July 2025.
