“蛟龙号”载人深潜器是我国首台自主设计、自主集成研制的作业型深海载人潜水器,设计最大下潜深度为7000米级,也是目前世界上下潜能力最深的潜水器。“蛟龙号”可在占世界海洋广阔海域中使用,不过距离地球海洋已知的最深处马里亚纳海沟底部的10,911米仍有相当距离,对于我国开发利用深海的资源有着重要的意义。 “Dragon No. ” manned deep submersibles is China’s first independently designed, self-integrated research and development of deep sea manned submersibles, the maximum dive depth of 7000 meters, is the world’s most submersible dive . The “dragon” can be used in a vast area of ​​the world’s oceans. However, there is still a considerable distance from the bottom of the Mariana trench at the deepest depth known to the Earth’s oceans, which is of great significance to the development and utilization of deep-sea resources in our country.
