Hero image

UDT 2021 will now take place on 15-17 December

The event has been delayed due to the ongoing impact of Covid-19. We are confident the new timeline will allow us to welcome international attendees to the show.

Our host city remains unchanged, and we look forward to reuniting the undersea defence community in Rostock - home to the German Navy HQ. Ahead of the live event, we will be running the DisTec Undersea Challenge - an online competition showcasing disruptive technology innovations in the UDT domain.

All exhibitor bookings will be valid for the rescheduled dates.

December dates clarification

Please note, the event dates have shifted from the timeline previously communicated by one day. This amendment is to ensure UDT has sole use of the exhibition hall throughout the build-up, open and break-down phases of the event. In line with Covid-19 protocols, this will help to ensure the safety of all participants. 

What is the DisTec Undersea Challenge?

DisTec ChallengeIn light of the disruption caused by Covid-19, we have been exploring digital opportunities to enable our event community to convene virtually and celebrate recent developments.

The DisTec Undersea Challenge invites innovators and progressive organisations to showcase new products or concepts currently in developments which have the potential to disrupt the future of undersea defence. All shortlisted entries will be displayed on the Challenge website, creating a showcase of emerging solutions. An independent judging panel will then select three finalists based on a series of innovation assessment criteria.

The challenge will culminate with a Grand Final on 14 July 2021. The session will be broadcast as a free-to-attend webinar.

Further information on how you can take part, as an entrant or viewer, will be available shortly.

Travel and accommodation

UDT 2021 will take place at HanseMesse Rostock, located 8km from the city centre. The venue is accessible by public transport, with connections to major transport hubs and landmarks across the city. 

We chose Rostock to host UDT 2021 as it is home to Marinekommando - the high command of the German Navy and staff of the Inspector of the Navy, the Navy's highest commander.

Germany has been a great location over the years for UDT and we are excited to return in 2021!
