Chinese submersible explores deepest region of Earth

"We have once again set a record for the maximum diving depth of an unmanned underwater vehicles and made a breakthrough in the continuous, stable, and reliable scientific research and application of unmanned underwater vehicles," Tang said.

Experts say the Haidou-1 has obvious advantages in many fields, including targeted explorations, seabed topography, geomorphology exploration, real-time image live broadcasting and target online recognition. It supports the scientific investigation of the abyss below 10,000 meters.

Haidou-1, which was developed by the institute under the auspices of the Chinese Academy of Sciences, was designed to bring high-tech to deep-sea research.

It completed its 4,500-meter sea trial in the South China Sea in August 2019 and the 10,000-meter dive in the Mariana Trench in May 2020.
