About DSEI 2025

DSEI connects governments, national armed forces, industry thought leaders and the entire defence & security supply chain on a global scale. With a range of valuable opportunities for networking, a platform for business, access to relevant content & live-action demonstrations, the DSEI community can strengthen relationships, share knowledge and engage in the latest capabilities across the exhibition’s Aerospace, Land, Naval, Joint, Security, and International Zones.

Why Attend DSEI London?

Playing a crucial role in bringing together governments, the armed forces and the wider industry together, DSEI UK enables defence and security product manufacturers to get directly in front of military and specialist procurement teams from around the world.

Featuring live demonstrations, presentations, theatre briefings, VIP programmes, and focused networking opportunities and events, the DSEI exhibition brings into sharp focus the importance of integration across the operational domains: maritime, land, air, space, and information.

DSEI Exhibition Hubs

Future Tech Hub: The Future Tech Hub at DSEI, brings together Innovation, Cyber and Communication Hubs, providing a meeting place for the defence community to discuss topical subjects

The largest and fastest-growing area of the show, the Future Tech Hub has tripled in size since 2021 and is designed to supports exhibitors looking to break into or strengthen relationships within the defence industry. Exhibiting MoD stakeholders include the UK Strategic Command, DASA, Dstl, Defence & Equipment & Support.

Manufacturing Hub: DSEI’s Manufacturing Hub supports UK manufacturers to break into the defence sector and strengthen their relationships within this industry, including with prime contractors who rely on skills and technology to deliver complex equipment programmes.

SMEs looking to exhibit at DSEI for the first time, can purchase discounted pods through the DSEI Springboard Scheme, aimed at supporting SMEs to achieve new heights and reach new audiences.

Medical Hub: The Medical Hub at DSEI offers practical demonstrations of the latest life-saving technologies and equipment, providing a dedicated area for those at the forefront of military medicine, ranging from senior commanders, policy advisers and planners to doctors and medics operating on the front line.

A robust and responsive defence medical capability is essential to both military and civil contingency operations. The service is being called upon to meet an increasingly broad set of challenges, ranging from support of forward deployed operations to large scale pandemics, both abroad and at home.

Space Hub: The DSEI Space Hub recognises the ever-growing dependency on the domain as global militaries create dedicated branches for space operations. Fully supported and enhanced by Dstl and UK Space Agencies which exhibit within the Hub, DSEI provides a platform to share and discuss next generation technologies.


“DSEI works in close partnership with the UK Ministry of Defence, the Department of Business and Trade, and the UK Armed Forces. Without their continued influence and support, DSEI would not be able to provide such a range of valuable opportunities for networking and platforms for business. We look forward to seeing you at DSEI 2025” – Grant Burgham, DSEI Director
