Manned Submersible Breaks China's Diving Record

China's new deep-sea manned submersible Fendouzhe, or Striver, set a national diving record of 10,909 meters on Tuesday in the Challenger Deep, a 11,000-meter chasm located at the bottom of the Mariana Trench in the western Pacific Ocean. 

The submersible first broke the 10,000-meter milestone by descending to 10,058 meters on October 27, 2020. The world's current deepest diving manned submersible is DSV Limiting Factor, which reached 10,927 meters last year. 

These deep-sea vehicles could help collect samples and data from the deepest part of the ocean for hydrothermal, geological and marine biological research, as well as study the human impact on the area. 

In 2016, scientists and engineers from the teams behind China's Jiaolong and Shenhai Yongshi (Deep-Sea Warrior) submersibles launched a project to create a manned underwater vehicle capable of surveying the entire ocean. The vehicle was later named Fendouzhe. 

Fendouzhe, one of the world's deepest-diving manned submersibles, is capable of carrying up to three passengers to conduct scientific research in the deep sea. It is electrically powered and can operate for around 10 hours underwater. 

Almost all of the vehicle's technologies and instruments were developed by Chinese researchers, according to the China Ship Scientific Research Center.
