Successful trial of China's deep-sea submersible pave way for future maritime research

The successful deployment and accurate recovery of China's first 10,000-meter-class manned submersible "Fendouzhe" is paving the way for the country's future deep-sea research. The Fendouzhe, or Striver, completed another 10,000-meter-class sea trial on Monday.

It successfully landed on the bottom of the Mariana Trench in the Pacific Ocean and retrieved three operating tools previously laid on the ocean floor. To prepare for long-term deep-sea observation, Fendouzhe made three dives in seven days, exceeding depths of 10,000 meters.
