No he is not. He also routinely posts fan made CGI without stating it. But he posts a lot of PLA things so he is worth following. You just have to ignore his content about future platforms unless he is providing resources.

Speaking of the sub in the picture, it is basically a generic "cigar" shaped sub with the sail of the 039D. I don't think it will resemble the 095. Though I would like to see angled midship torpedo tubes on the 095 as it allows for a much larger bow sonar.

Thanks. Also I believe 095 would have some VLS tubes

In 2000, PLAN SSN fleet consisted of 091s and 092, so it was more like early 1950s level. Keep in mind that when they first developed the submarine reactor for 091, it 2 decades before they connected their first domestic Qinshan nuclear reactor onto the grid. I would not dare to spend prolonged period of time next to a 091 reactor. the current PWR technology vs back in 2000 is night and day. If you just look at

, the domestic nuclear reactor technology really only reached 2nd generation with CNP600 in 2010 and only reached 3rd generation with Hualong One in 2021.

You can see that if they finalized on a nuclear submarine reactor design in 2011, they'd basically be using a reactor utilizes 2nd generation technology and then it will take another 3 years to launch the boat and 3 more years after that for it to join service. So if they have a modern reactor designed in 2020 with 200 MWt, then it probably won't be on a boat that's in service until 2027.

Even that is still very good.

Remember, Ohio class's SG8 reactor is 2nd generation technology from the 1970's, and it is still very advanced even in today's standard. Ohio class is deadly quiet, even quieter than the early Virgina class !!

If China's sub reactor tech can reach SG8, it will be world class !!

Ohio SSBNs are quieter than Virginia SSNs not because of their reactors but because of their very large displacement - twice that of the Virginia. A large boat provides you ample room for mounting nearly all of your machinery on noise/vibration-absorbing foam-like/rubber-like material as well as installing various other noise/vibration-cancellation equipment.

From an engineering perspective, I see nuclear submarine stealth as being primarily about:

1. rafting (and therefore isolating) the internals from the outer pressure hull
2. having a natural flow reactor without noisy pumps
3. reducing any other discrete harmonics or noise sources that travel well in water

So submarine stealth isn't about a single magical technology, but simply heavy engineering graft and design experience.

It also seems that having a larger diameter pressure hull doesn't particularly increase quietness, assuming you have to have rafting anyway and if this is combined with a single pressure hull.

Yes, indeed rafting is very important.

Check out this article about rafting for a US virgina class submarine.
