About the DSEI London Exhibition

The DSEI conference features a comprehensive support programme. Each edition operates under a specific theme. For instance, the central theme for one iteration was “Integrated Response to Future Threats”. This central theme influences the subjects selected for the Forums, seminar and keynote speeches. Among the main events is the detailed exhibition, where exhibitors present their latest products. This includes all levels of the supply chain, such as digital solutions and others. The DSEI exhibition grounds contain several Zones (Land, Naval, Security, Aerospace, and Joint) and Hubs (Space, Future Tech, Medical, and Manufacturing).

Each of the Zones features at least 60 categories. The Aerospace Zone, for instance, has over 100. It presents wares such as AI, missiles, flight simulators and others. The Land Zone is another exhibition zone. It features wares, like artillery, EOD, countermeasures, logistics, and body armour. The Naval Zone presents the latest naval vessels and technology. It includes a dockside section for live demonstrations of maritime capabilities and can contain additions such as visiting warships. The Security Zone presents equipment, strategies, technologies, and systems for countering high-priority threats such as terrorist attacks via its more than 60 categories. The Joint Zone displays products that can serve the entire Defence and Security Community via its over 100 categories. Such include sectors such as communications and defence infrastructure.

The Hubs serve as dedicated platforms for presenting different lead sectors. The Space Hub, for instance, displays the latest communication and space applications. The Future Tech Hub is the central location that unites Innovation, Cyber and Communication. It serves as the defence community's meeting place for discussing important subjects. The Medical Hub is the showcasing location for defence medical research and simulations. It contains a series of interactive stands and a demonstration area. Attendants can earn awards at the demonstration area by showing their medical abilities. The Manufacturing Hub is where UK newcomer manufacturers can network with the industry. This includes meeting with prime contractors. Among the services which receive a presentation in the area are consultancy services and hybrid manufacturing.

Each Zone contains a specialist Forum (Joint Forum, Naval Forum, Land Forum, and others). The Forums enable dialogues between attendees around the current edition's core themes. For instance, one edition focused on future operational requirements, skill retention, information exploitation and industry engagement. Similarly, each Hub contains a specialised Theatre focused on the core themes. For instance, the Manufacturing Theatre demonstrated the latest supply chain management developments via live demonstrations. The Medical Innovation Theatre also featured live demonstrations. Yet, the wares on display were related to the latest Operational Patient Care Pathway innovations. This includes future requirements for modern military healthcare systems.
