09III/09IV (093/094) Nuclear Submarine Thread

Of course.

Just so people can visualize what I mean, this is roughly an approximate of what I mean in terms of fitting the same number of cells in the about the same length, but in tripack tubes.
The greater beam/width of 09V means two columns of the tripack tubes can be co-located adjacent to one another in the style of Yasen or most SSBNs.

(Exact proportions of the submarines are of course simplified, but it is the VLS bank size relative to one another which is more important)

What would be the advantage of using a cylindrical VLS setup as opposed to rectangular? I'm curious in a general sense, not specific to 09V.

My understanding is structural ease of construction (both for the cells themselves but also inserting them structurally into the submarine), and also some benefits in compactness as multipacks means some systems and shrouding do not need to be duplicates for each individual cell.

so now that 093B is out in the sea and probably even conducting initial patrols. Which seems quite likely 3 years after the first one launched that it is commissioned by this point. I think maybe this article is coming up because people inside the pentagon are getting the initial reports on their performances and raising the alarm.

I remember back in the late 2000s, when 093s were first doing their sea trials and I was pretty excited by the news. Soon enough, articles came out basically where US navy was just saying they were really loud and later USNI updated their charts on just how loud the first 093s were.

So, this is quite the expected confirmation. I think it's reasonable at this point to think 093B is at least as quiet across the spectrums as the last bunch of LA class and possibly better than that.

Which imo, is enough to sail undetected once you get past the 1IC line without SSN tailing it.

That ridiculous Wuchang sinking story just won't die, unfortunately.

Or it could be 1st 09V. To be honest we cannot be sure of 09IIIB numbers because some of what we thought were new launches may have been older boats in for repair/refit. This seems to have been the case with the most recent evolution in that dock before this one.
There's no high resolution imagery available that I can find for the date in question - nor those around. Last is mid-August.

I have looked at the AIS data for the tugs however, and again they didn't move for the period in question up until today. I would have expected them to have moved over at some stage if a new one had been brought out to take over to the piers.

My feelings are it's an older one again.

Interestingly, one of the tugs did go out into mid-Liaodong Bay on 31st July for a few hours, possibly escorting a sub in and out. It hung around mid bay for about an hour, possibly for a quick dive test.

I am talking about the one on the barge as of 7th September. If no tug activity, this suggests a new launch rather than bringing an older one into the dry dock (which would presumably require tugs).

Still there today:

Yep. I mean that too. They'd need the tugs to take it across if it's come out the halls too.

I also measured it at 103 metres give or take a couple. But hard to tell with low res imagery.
