The DSEI 2025 dates, 9 - 12 September, are on the agenda of professionals in the defence and security industries worldwide. Recognised as one of the leading trade fairs in this sphere, the Defence and Security Equipment International event will gather community members from over 90 countries at ExCeL London. Around 1,600 exhibitors will demonstrate their products and services during the four-day DSEI. More than 45,000 trade visitors will benefit from the exhibition of the latest innovations and the platform for networking and knowledge exchange.
The main theme of DSEI 2025 will be Preparing the Future Force, examining the role of human factors in the context of the ongoing transformation of the defence sector and any challenges it might encounter. Leveraging both innovations and international cooperation to increase the ability to detect, respond to, and even predict threats will be crucial for the armed forces of tomorrow. DSEI participants will discover solutions throughout the event’s industry-themed zones and hubs, including cyber security, weapons, ammunition, and space communication technologies.
DSEI 2025 will feature three key sub-themes. Securing Advantage will address supply chain security, agile acquisition strategies and dual-use technology. Driving Advantage will focus on the digital approach in warfare, involving AI, autonomous systems and cyber defence. Maintaining Advantage will delve into new developments in recruitment and management. The trade show will host live demonstrations, workshops, pavilions, conferences, and forums on relevant topics.
