7000 ton is the next (after 09 III) (full sized) SSN "New Type SSN"

Here you can see there are two subs he talked about, the New SSN and the Small SSN

I am very curious about the type of reactor in the small SSN, how does it work, does anybody have a bigger and clearer photo of it?
It is of three-loops design rather than two-loops used by conventional SSN. My focus is the right most part depicting the 3rd loop in color green. What kind of electricity generator is it?

The 3rd loop look like condenser to cool down the waste heat from steam turbine and not steam generator. It goes back to Steam generator(2nd loop)

I think there is no steam in any of the 3 loops. It says in the slide to be low temperature and low pressure reactor.

In one of the speculations that I read else where, 2nd loop takes heat from 1st loop by heat exchange built inside the fusion vessel. That speculation believes that one implementation could be Sterling engine, no steam turbine. I can not be sure of the slide showing something in that idea, that's why I asked for higher resolution. Using Sterling engine instead of steam turbine makes it less powerful in terms of direct drive or electricity generation, it is a disadvantage, but matches very well with the statement in the slide that the small SSN has a lower speed.

If there is steam, it can not be called low pressure (compared with the convention 2 loop reactor).

Not a bad view ... Chinese 27th flotilla leaves the Gulf of Aden for a diplomatic tour

That's an old photo from the 23rd mission to Gulf of Aden.

And to be honest, I have the sneaking suspicion that this photo is even older, possibly from years ago and was simply reused as a file photo.

Also, not everything posted on Herik's Twitter feed is correct or is breaking news. Anyway, I'd imagine most of us have access to his Twitter feed, along with that of OedoSoldier.

There are reports that 611 formally submitted the J-20 proposal for the PLAN's next-generation fighter tender. It will go into direct competition against the FC-31 design. From the rumors so far, it seems that the J-20 design submitted by 611 will be a full-sized variant (roughly the size of the F/A-18E/F).

Best of luck to both teams, and it'll be nice if the forum could have another bet (just like with the carrier program).

The J-20 is bigger than a super hornet though.

I'm sorry if I offended you by posting an "old photo" ... I did not realize it. And multiple ppl use photos from the aforementioned twitter feeds, is there anything wrong to rep9st them on SDF as you suggest for the ppl who don't have access to twitter? It seems as if you're blatantly accusing me of deliberately posting old photos... it was a honest mistake and I apologize. I'll will be careful next time but do keep in mind I'm new to SDF ...
