DSEI 2027 takes place from 7 to 10 September 2027 at ExCeL London in London, United Kingdom. Defence and Security Equipment International (DSEI), presented by the organiser as the flagship defence event for the UK, is organised by Clarion Defence & Security, part of Clarion Events.
The 2027 edition is held under the theme “Delivering the Integrated Force”. One of its four sub-themes, Digital Transformation, AI and Cyber, lists autonomous and uncrewed systems among its core topics. The show floor is divided into zones including Land, Naval, Aerospace, Space, Tech, Manufacturing and Medical; the Naval Zone covers unmanned surface and underwater technologies, and the Land Zone has featured AI and unmanned systems for ground defence.
Trade press coverage of DSEI 2025 described counter-unmanned aircraft system (C-UAS) technologies as a prominent focus of that edition.
