DSEI 2023 Update

Industry players may discuss the future of defence systems at the 2023 edition of DSEI from September 12th until September 15th, 2023. DSEI will be hosted by ExCeL London in London, the UK. Up-to-date COVID-19 health and safety precautions will not be implemented at the venue. This is due to the removal of the country's pandemic-related safety policies.


DSEI stands short for Defence Systems and Equipment International Exhibition and Conference and has been at the forefront of innovation across private and military defence circles. The event is held in London, UK every two years with editions falling on odd years.

What can you hope to discover under the roof of ExCeL London? The full assortment of technology and solutions for the aerospace, naval, land and security sectors. Product categories extend to weapons, tactical equipment, ammunitions, emergency equipment, first aid equipment, infrared systems and radar equipment.


  • There will be around 30,000 attendees;
  • Approximately 1,700 exhibitors are expected to present their defence technology solutions;
  • You will be able to meet representatives of the governmental and private sectors;
  • The event will host 6 seminars dedicated to the topic of security;


Clarion Events Ltd. puts together DSEI for a total of four days and opening hours are from 09:00 am in the afternoon until 17:00 pm. The first day begins an hour early to account for registration, and the last ends an hour early.

Audience and statistics

Another reason why DSEI has become a big platform for supply and demand is the fact that there’s a lot of effort put into devising countermeasures against cyber-crimes. Security is one of the big subjects with 6 seminars tackling current challenges while CYBER HUB dives deep into subjects like electronic warfare, telecommunication systems and high-tech surveillance. The audience breaks down into influencers, decision makers, military buyers and a whole line-up of VIP guests.

2021 Edition

The 2021 edition of DSEI was of great importance for the global defence & security industry. This is due to the rendition representing the successful restart of the face-to-face fairs for both the sector and the UK.  The rendition occurred as a hybrid event consisting of a face-to-face exhibition and a digital platform. It occurred between September 14th and September 17th at ExCeL London. The edition featured new additions, including the introduction of the ‘Future Tech Hub’. It was a dedicated hub that combined Innovation, Cyber and Communication. The hub allowed professionals to examine novelties related to digitalisation, cybersecurity, networks & communications.
