Description
The Qianlong No. 2 Chinese Autonomous Underwater Vehicle (AUV) unlike many submersibles, looks like a fish. It is the first time in the world to apply a non-rotating body flat fish shape design, which is beneficial to reduce the vertical surface resistance, facilitate its vertical climb in complex seabed terrain, and enhance surface navigation. ability. The Qianlong No. 2 is China's most advanced deep-sea autonomous underwater robot, which has reached the international advanced level.

Variants
Qianlong No.1
“Qianlong No.1” is a “Twelfth Five-Year” project relying on the China Ocean Mineral Resources Research and Development Association. It was led by Shenyang Automation Institute and jointly developed by the Institute of Acoustics of the Chinese Academy of Sciences and Harbin Engineering University. "Qianlong No.1" is domestically-developed deep-sea exploration equipment. Its main task is to discover and find the area where resources are located, to detect the marine elements on the seabed, and to provide a basis for evaluating resource reserves and commercial exploitation value. Maximum Depth 6,000 m.
Qianlong No. 3
The first sea trial of the Qianlong No. 3, an upgraded version of the Qianlong No. 2, is expected to be conducted this April of 2018.

Mission
Operating without monitoring from its mother vessel, taking multiple acquisition sensor modules onboard during the dives, and for the exploration operations of deep-sea mineral resources such as polymetallic sulfides.
Maximum Depth
4,500 m
Ballast System
It has sinking ballast iron and floating ballast iron installed on it. After launching, it dives under its own gravity. After descending to a predetermined depth, it automatically throws away the sinking ballast iron and then starts the operation. After completing the operation, It will automatically throw away the floating ballast iron to achieve automatic floating, and the staff will then recover it to the mother ship by remote control hook or rope throwing.
Cameras
Yes.
Magnetic Detector
Located on the stern.
Magnetometer
Yes, used to detect magnetic anomalies and Polymetallic Sulfide.
Note
Qianlong No. 2 is China's most advanced deep-sea autonomous underwater robot, which has reached the international advanced level.
