Second Chinese Submarine Drone Mothership Emerges
Nearly a month ago, we reported on a uniquely configured vessel that was far along in its construction at Hudong-Zhonghua Shipyard on Changxing Island in Shanghai. The intentions behind this design appeared to be as an uncrewed underwater vehicle (UUV) mothership, capable of deploying a handful of very large vehicles or many more smaller ones via its stern garage door and well deck. Its large pylons would be used to lift the vessels up and down out of the water and to different levels in the ship. Now it appears China has not just one, but two of these vessels nearly complete.
Make sure to read our initial report on this vessel configuration for full context by clicking here.
The new image was taken in Guangzhou and the vessel has a near identical shape, but with smaller proportions and minor changes to its overall moldline, compared to the larger one in Shanghai. This new vessel appears to be about a third smaller overall than its counterpart. The lift towers number six in total instead of six larger ones and six smaller ones on the Shanghai vessel. Regardless, the major design features are all there, including the flight deck and hangar behind the forward superstructure, the location of the smokestacks, and so on.
While two of these assets could still be considered largely intended for experimental use, a growing fleet would have increasing tactical and even strategic importance. Being able to easily launch and recover large numbers of UUVs, or a few very large ones, far from Chinese shores would provide an asymmetric capability. A fleet of ships that is dedicated to deploying, recovering, and tending to these systems, some of which can remain on patrol for very long periods, would be a major indication of how important China sees UUV operations as part of its future strategy.
There have been rumors that these vessels are part of a larger overall program that will see more ships with similar capabilities constructed. Once again, this would be a strong indication that these vessels’ utility will go beyond testing and limited operational use cases. The launch and recovery of large UUVs remains a conceptual work in progress for the U.S., with nothing similar in the U.S. Navy’s inventory, as we discussed in our original post.
Large long-range UUVs can be used for many tasks, from mapping the sea floor to hunting submarines and ships to searching for mines to launching cruise missiles and drones to being turned into immensely destructive weapons in their own right that can circumvent traditional strategic defenses. For China, providing a credible threat to America’s outposts deep in the Pacific and even the U.S. seaboard would be on the table.
There is speculation online as to where exactly this vessel was built. The first place that came to mind is Guangzhou Shipyard International’s (GSI) facilities on Longxue Island, just southeast of the city of Guangzhou. GSI is a subsidiary of the China State Shipbuilding Corporation (CSSC). It is here that many of China’s most unique vessels are born. These include drone test ships of various kinds, massive beach landing barges, and giant supply ships. Upon closer review of archival satellite imagery, we can say for certain that GSI did build this ship. An image from October 2nd shows it peeking out of a covered graving yard area at the facility prior to launch.
The emergence of two of these large UUV tenders in such a short period of time underscores China’s major bet on the technologies they will support. If more ships are added to the currently known fleet of two, a clearer picture of the People’s Liberation Army Navy’s large UUV plans, and its expeditionary potential, will come into focus.
