  • DSEI is a highlight within the defence calendar, I use it to find out what the most recent developments are in every technological area affecting for defence. Without DSEI I fear this sort of interaction, information exchange and knowledge of developments across all domains would be lost. DSEI is an invaluable international biannual event .

  • DSEI is a fantastic showcase for defence companies where international buyers, sellers, developers, thinkers, educators and the trainers can all get together. The UK defence industry is looking to recruit more engineers, scientists and developers into 200,000 jobs and up to 10,000 apprentices within UK defence companies. DSEI is an excellent tool to highlight the challenges the industry face as well as showcase its capabilities domestically and overseas.
