About - UK Defence and Security Relationships Across Europe

Mapping the evolving UK defence and security policy relationships with allies and partners across Europe. (The data is correct as at 6 April 2023.)

About the Project

This online resource is the output of a joint project between RUSI and the Konrad-Adenauer-Stiftung under the European Security in Transformation programme. The project aims to create a user-friendly interactive research tool which consolidates information on the UK’s defence and security relationships in a single place. The current map represents Phase 1 of the project which focusses on 15 bilateral relationships. Phase 2, which will cover the remaining European relationships, will be delivered by the end of 2023.

European security is undergoing a period of transformation, as is the UK’s relationship with Europe, for two central reasons. First, the UK’s departure from the EU in 2020 was a significant structural change to the European security architecture, and required the UK to sign additional defence and security agreements with EU member states. Second, the Russian invasion of Ukraine in 2022, and the European response, have transformed the European security environment. The pace of change is significant, as are the new frameworks and initiatives that are driving Europe’s response in different functional areas.

As the security environment changes, so will the European security architecture. These structural developments have created an overlapping mosaic of multilateral, minilateral, trilateral and bilateral groupings which all exhibit different political, diplomatic, defence and security responsibilities and commitments. This map helps to understand this complexity and facilitate further analysis.

Project Objectives

  • To map the UK’s defence and security relationships with European partners.
  • To provide a resource to understand complex defence and security relationships more easily, aiding further analysis.
  • To highlight which defence and security relationships are priorities for the UK and to identify potential gaps as the UK develops as a European security actor.
