In the early morning of November 10, China`s first ten-thousand-meter-class manned deep-sea submersible, named "Struggle", dived into the water under the Mariana Trench. At 8:12 Beijing time, the Struggle reached the bottom of the Mariana Trench at a depth of 10,909 meters. This is China's first deep submersible to enter the bottom of the Mariana Trench.
In terms of dive depth alone, this time the Struggler`s dive depth can rank third in the world, second only to the famous Tilias 10916 meters and the 2019 DSV Limiting Factor reported 10928 meters.
What Helping China Struggle achieve this world-renowned achievement is the 10,000-meter pressure-resistant titanium alloy manned cabin developed by Chinese titanium alloy technology company.
