On November 10, 2020, my country's "Struggle" manned submersible successfully sat on the bottom of the Mariana Trench with a depth of 10,909 meters. On October 27 this year, the Struggle successfully dived to a depth of 10,058 meters in the Mariana Trench, setting a new record for China's manned deep diving.

It is understood that the Struggle is a 10,000-meter manned submersible developed by China. It was established in 2016 and is undertaken by a scientific research team based on the research and development capabilities of the Jiaolong and the Deep Sea Warrior manned submersible. On June 19, 2020, China's 10,000-meter manned submersible was officially named: Struggle. At 7:42 on November 10, the "Struggle" manned submersible successfully dived and exceeded 10,000 meters in the Mariana Trench.

It is understood that in addition to manned submersibles, my country also has many unmanned submersibles such as "Haidou", "Haiyan" and "Haiyi". Among them, the "Haidou" has two modes of remote control and automatic operation. It is China's first 10,000-meter scientific research submersible. Editor/Xu Shengpeng
