Royal United Services Institute

What Royal United Services Institute does

The Royal United Services Institute (RUSI), founded in 1831 and registered as a charity in England and Wales (Charity number 210639), is the world's oldest defence and security think tank and the United Kingdom's leading institution in this category. Headquartered in Whitehall, London, with 101–250 employees, RUSI produces independent research, analysis, and convening activities across geopolitical competition, military sciences, cyber and emerging technology, terrorism, organised crime, and the intersection of finance and security. Its product portfolio comprises research publications (commentaries, insight papers, research papers, policy briefs), the RUSI Journal, five podcast series (Global Security Briefing, Talking Strategy, Suspicious Transaction Report, Bridging the Oceans, Mind the Gulf), and 200+ annual events, conferences and workshops, organised through thematic programmes such as International Security, Cyber and Tech, Military Sciences, Terrorism and Conflict Studies, Organised Crime and Policing Studies, and the Centre for Finance and Security.

RUSI serves UK and international government policymakers, defence ministries, NATO and other military officials, members (4,000+), and media organisations (BBC, CNN, Financial Times, Newsweek, Channel 4 News, Sky News, The Independent). Its monetisation rests on a subscription membership programme that bundles publications, members-only events, and expert networking; paid events and workshops; publication and journal sales; and competitive research grants from governments and institutional funders (e.g., a CAD 317,806 grant from the Government of Canada in March 2024 for a two-year study on radicalization potential in gaming platforms). Geographic reach is listed across Europe, the Middle East and North Africa, Asia-Pacific, the Americas, Sub-Saharan Africa, Russia/Eurasia and Transatlantic Security, with partnerships including the Regional Institute for Security Studies (RISS) in Tbilisi.

The team is led by Director-General Rachel Ellehuus, with named Directors across CFS (Tom Keatinge, ex-J.P. Morgan), Cyber and Tech (James Sullivan, ex-Deloitte / UK National Crime Agency), Military Sciences (Matthew Savill, ex-Ministry of Defence), Terrorism and Conflict Studies (Dr Jessica White), and Organised Crime and Policing Studies (Cathy Haenlein). Oana Lungescu, formerly NATO's longest-serving Spokesperson (2010–2023), is a Distinguished Fellow. RUSI operates as a non-profit charity without a parent company and without proprietary technology products; its distribution is centred on rusi.org, the membership programme, podcast platforms, and high-credentialed events.

Direct peers

• Chatham House (Royal Institute of International Affairs): Another leading London-based foreign policy and international affairs think tank, with a similarly broad research mandate, membership model, and event-driven engagement strategy, making it RUSI's closest UK peer on international affairs and convening.
• International Institute for Strategic Studies (IISS): A direct competitor in defence and security analysis, publishing the Military Balance and Strategic Survey, convening high-profile security conferences, and serving overlapping government and military audiences globally.
• Center for Strategic and International Studies (CSIS): A major US-based defence and security think tank with comparable government-focused research, publications, and high-level convening, often partnering with or competing against RUSI in transatlantic policy debates.
• Atlantic Council: A US-based think tank focused on international security and transatlantic relations, with a comparable product mix of policy reports, events, and media engagement targeting the same UK/US/EU policy audience.
• Carnegie Endowment for International Peace: A global foreign policy think tank producing high-quality analysis, convening events, and publishing reports on international security and geopolitics, competing with RUSI for media attention and policy influence.
• International Crisis Group: A think tank that combines global conflict analysis and field-based research, overlapping with RUSI's international security programme on regional conflict and policy advice to governments.

Broad incumbents

• RAND Corporation: A much larger, US-headquartered policy research organisation with deep defence and national security work, overlapping substantially with RUSI on military sciences and cyber research and frequently winning similar government study contracts.
• Brookings Institution: A large, well-resourced US think tank with deep coverage of foreign policy and security, frequently cited in the same media outlets and policy discussions as RUSI but operating at significantly greater scale.

Emerging players

• Center for a New American Security (CNAS): A US-based defence and security think tank focused on US national security policy with similar policy-report and event-driven engagement, generally seen as a younger, more US-centric counterpart to RUSI.

Others

• Royal Institute of International Affairs (Chatham House): While a peer organisation, Chatham House also occasionally functions as a co-collaborator in the UK think tank ecosystem (e.g., sharing advisers), so the relationship has both competitive and collaborative dimensions.
