DSEI UK

DSEI UK is a defense and security exhibition held at Excel London. It brings together international governments, ministries of defense, military officials and all UK front line commands with exhibitors from across the defense supply chain. The show floor is organized into zones, with exhibits, features, networking areas and conference theatres.

Attendees include senior military leaders, government representatives, procurement decision-makers, manufacturers and suppliers. Exhibitors range from large manufacturers to technology companies, alongside international pavilions where government agencies, trade associations, media outlets and service providers represent their countries’ defense and security sectors.

For readers following aircraft components and uncrewed systems, the Aerospace zone covers the aerospace supply chain, while the Tech zone addresses AI, cyber security and digitalization. Further zones cover land, naval, space, medical and manufacturing. Subjects discussed across editions include autonomy, aerospace, maritime, cyber and space-based capabilities, and visitors can see live demonstrations and try products and services hands-on.

Each edition is organized around an overarching theme set by the organizers. Visitors use the show to meet suppliers and manufacturers, identify business opportunities, and understand global defense priorities and procurement requirements across land, sea, air, cyber and space domains. Official media partners include defense news outlets and a magazine dedicated to uncrewed systems engineering.
