The global event for undersea defence and security

According to Shephard's Naval Vessels Market Report, the global market for conventional submarines alone is expected to increase to US$8.0 billion by 2029. Cumulatively, the market is expected to have a value of US$90.3 billion over the next decade.

Undersea Defence Technology (UDT), as the largest global event dedicated to the undersea defence industry, is a multi-faceted exhibition and conference reflecting the community’s desire for continuous learning and development.

Designed to equip nations to deal with an increasing diversity of threats and challenges, UDT brings together researchers, military end-users and professionals spanning the entire supply chain to evaluate developing solutions in one of the harshest environments known to man.
