Ocean is the most realistic space to solve conflicts among population, resources and environment. The development and utilization of marine resources and space are inseparable from various types of deep-sea equipment. In 2020 significant progress was made in the research and development of deep-sea equipment at home and abroad. Focusing on the research and development of manned/unmanned underwater vehicles, this paper introduces the international and domestic research hotspots and highlights in 2020, analyzes the international status of China's marine technology, and provides some suggestions on future development directions of China's deep-sea submersible field.
