DSEI 2025
The global platform for defence and security
Our engineering and technology capabilities are not only redefining sovereign defence support across the globe but also delivering defence engineering fit for the future.
Watch our video to see how we showcased our leadership in lifetime engineering at DSEI 2025.
In addition to our main stand, we also had our speciality GLV vehicles on display in the main boulevard and a stand dedicated to our immersive training experience – BITE.
On the main stand, visitors saw our AH140 frigate interactive model, our sub dock model and me colleagues from our five sectors – Marine, Nuclear, Land, Aviation and Mission Systems to talk about the ways we’re committed to defence engineering that builds the bigger picture, and the benefit that our holistic approach has in ensuring every action contributes to a larger, interconnected vision, delivering the very best outcomes for our customers.
