    The story is bullshit but the pier is too shallow for a submarine to operate safely underwater.

    US nuclear subs, for example, need at least 50-60 ft (16-20 m) under its keel to navigate safely, otherwise they risk running aground in shallow waters. Smaller submarines are better at that, which is why for littoral (coastal) defense, it makes sense to have small Soviet/Russian-made Kilo class SSKs lurking in the coastal area, but it is too dangerous for nuclear subs to do so, not to mention that nuclear subs are far noisier than diesel subs like the Kilos running on batteries.

    Most submarines will sail from the pier to a minimum underwater depth before diving. So it’s very easy to tell if a submarine is “underway” (submarine leaving the pier) or not.

      You are right. Thats why no nuclear submarines are made in fucking Wuhan and the facilities there arent even equipped for that. If that changed somehow you would see massive and visible constructions and renovations there for the last 1-2 years. Only conventional submarines are made there. Nuclear chinese subs are made near the coast as well and the facilities there have no issue with capacity. China sudenly deciding to make nuclear subs 5k km upstream where the river has an average dpeth of less than 10 meters (a depth that even mini nuclear subs would be fully visible by satellite if submerged) for no reason ridiculous.

      Also if you look into the reporting this is literally the same debunked story from months ago that goten new life just cause they asked some random us officials and showed them the picture and he said “yeah thats plausible” .Thats the official confirmation talked about in the reporting
