China plans to send crewed submersible to bottom of Arctic seabed
The country announced a new exploration vessel as part of its growing presence in polar regions

The vessel has been designed to drop through a hole in the hull of the polar research vessel Tan Suo San Hao (Explorer Three), according to the developer, the China State Shipbuilding Corporation’s 704th Research Institute.
The developer said it had carried out a series of tests, including underwater docking and low-temperature operations, but has not disclosed many details of the vessel.
It said the country had previously been forced to rely on foreign technology but had now developed its own systems that “can be widely used in the future for polar scientific research, deep-sea oil and gas mineral resource exploration and production, seabed pipeline construction and maintenance [and] search and rescue operations”.
