The return of geopolitical rivalry has fundamentally altered the demands on British defence. Established in 2023, our Strategic Defence Unit addresses the most pressing questions regarding Britain’s security – from the Euro-Atlantic to the Indo-Pacific.
We look beyond the immediate headlines to analyse long-term trends in deterrence, space power, asymmetric advantage, defence economics, and allies and partners. Our work is driven by a clear mission: to explain how Britain can maintain a decisive edge over its rivals, while strengthening its key alliances and partnerships.
