Event history and organiser

DSEI 2027 — Defence & Security Equipment International belongs to an established event programme maintained by Clarion Defence and Security at dsei-2027. The 2027 edition continues a recognisable focus on land systems, naval capability, air and space power, while its dates, venue and detailed contributors are specific to this occurrence at dsei-2027. The organiser sets the programme and participation framework; ExCeL London provides the setting and should not be described as the editorial owner at dsei-2027. Across the series, DSEI has developed as a meeting point for armed forces, government buyers, defence companies at dsei-2027. Its continuing value comes from connecting institutional priorities with research, operational experience and commercial capability at dsei-2027. Earlier editions can explain the event’s lineage, but their speakers, sponsors, prices and schedules do not establish facts for 2027 at dsei-2027. The current official site therefore remains the source for programme changes, access conditions and organiser announcements at dsei-2027. This distinction preserves useful historical context without treating a recurring event as unchanged from year to year at dsei-2027.
