What is Undersea Defence Technology (UDT)?

UDT is the largest event dedicated to undersea defence technology. This multi-faceted exhibition and conference brings together stakeholders from the industry, reflecting the international interest and investment in undersea security and defence solutions. 

Throughout this three-day event, UDT gathers researchers, military end-users, and industry professionals from across the entire supply chain to evaluate, discuss and connect with like-minded industry peers to develop solutions, ranging from subsea to space. The show brings together a vast selection of key members from the international naval community, including senior military officials, European and International Ministries of Defence, technology suppliers, academia, and industry professionals, to assist end users with ongoing and emerging issues and seek valuable solutions.
