The unmanned submarine “Hailong III” completed its first deep-water test in the western Pacific Ocean on Sunday.
The device entered at 5:20 in the depth area of 690 meters after being launched from the research ship Dayang Yihao (Oceano No. 1).
Chu Fengyou, the ship’s chief scientist, said the submarine, equipped with tools to drill rocks and sample handlers, took pictures of the crust of the seamounts and completed all the tasks planned for the test.
The “Hailong III”, which is able to submerge at a depth of 6,000 meters, on Saturday, performed a shallow sea test of 400 meters, also in the western Pacific.
The Dayang Yihao sailed last Tuesday from Qingdao, in the eastern province of Shandong, to carry out a 45-day scientific expedition. It is equipped with advanced scientific equipment, and transports the unmanned submarines “Hailong” and “Qianlong”.
