3. Deep-sea manned submersible Fendouzhe's diving record

China's new deep-sea manned submersible Fendouzhe (Striver) set off on Oct 10, 2020, for the 10,000-meter deep-sea diving operation in the Mariana Trench. During the expedition, it completed 13 dives, eight of which exceeded a depth of 10,000 meters.

It set a national record by diving to a depth of 10,909 meters in the Mariana Trench at 8:12 am on Nov 10, 2020.

Fendouzhe is the world's deepest-diving manned submersible, capable of carrying up to three passengers to conduct scientific research in the deep sea. With multiple breakthroughs in various key technologies, the Fendouzhe represents a milestone in the country's endeavor into deep-sea exploration.
