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.

UDT provides an invaluable platform for all stakeholders in the undersea defence community to come together, learn, expand networks and explore business opportunities and we look forward to welcoming you to ExCeL for UDT in London from 9 - 11 April 2024.
