Zero USV is a new collaboration bringing together more than 50 years of marine-specific design, build, engineering and operational experience into a unique new class of uncrewed surface vessels (USVs) – the 12 metre Oceanus12 class. This includes the experience and knowledge from the successful transatlantic autonomous voyage of the Mayflower 400 (www.mas400.com) which involved collaboration from MSubs and MarineAI. Zero USV enjoys a rich heritage that combines the research, marine build and artificial intelligence (AI) to deliver what will surely become some of the most renowned and successful USV deployments globally.
