Type-039A Yuan Class Submarine

Geo-location Of Thai Navy Submarine in China

Flag My latest Naval News article shows that China's new Wuchang Shipyard is pumping out Yuan Class AIP submarines (SSP). While I will not share all of the sources, there is some collaborating evidence which is easily accessible. In particular, it can be demonstrated that the keel laying ceremony of Thailand's first modern submarine took place there.

While the new location of the Wuchang Shipyard (it was in the center of town) are not secret per se, information has been incredibly limited. In particular the order books for naval vessels are not public. So the capacity and construction program of the shipyard is of great interest to defense analysts.

The ceremony took place on September 4, 2018. Photos of the event were posted on Thai and, to a lesser extent, Chinese websites. The press releases stated that the submarine was being built at Wuhan but naturally were scant on extra details. They did not specify the location or which construction hall. However we can geolocate the shed relatively easily using high resolution Google Earth imagery.

So the Royal Thai Navy S26T (Yuan Class variant) submarine is being built in the hall nearest the river. Through other sources we know that multiple submarines are under construction at the site with at least two fitting out at the same time. This means that other construction halls must also be in use for submarines. We can estimate that as many as 8 submarines (if not more!) could be inside the halls at once. Combined with the fitting out piers this represents a massive submarine building capacity. It seems unlikely at all slots would be in use at once, but the scale of construction is clear.
