DSV Shinkai

DSV Shinkai is a type of submarine used by the Japanese navy. It is a deep submergence vehicle, which means that it is designed to go very deep into the ocean. It is sometimes referred to as a "mini-submarine" because it is small, about the size of a school bus. DSV Shinkai submarines are used for research and exploration, and they can stay underwater for long periods of time. They are often used to study the creatures that live in the deep sea and to explore different shipwrecks.
