09X's pumpjet being partially above water suggests it's sitting quite high, compared to 093B's pumpjet being completely submerged. Unless 09X's pumpjet is significantly bigger?
09X is basically just a empty shell right now, most of the equipment and weaponry has not been installed yet hence it has a lower waterline compared to a fully fitted out 09IIIB

I was suggesting that there isn't much more of the submarine's hull submerged beneath the water surface than is visible from above, thus 09X having a largely similar beam as the 095 is unlikely, sorry for not being clear.

If you look at the pumpjet, you can only see the very top of it meaning the maximum beam is still submerged by quite a bit. Current measurements already puts it at 11m a tiny extra bit could put it at 12m similar to 09V.

What do you mean - not installed? Submarines unlike surface ships are built in sections with everything already inside pressure hull, before they are joined together. In case of double hull, some equipment may be installed later, but nothing major.

Only large equipments that could not be installed later on is there before launch but basically everything else including electronics, weaponry such as VLS etc are not.

I'm leaning towards the Huludao submarine being another Type-095.

So perhaps 09X is the testbed or first-in-class for a new SSN design?

If we go with these dimensions (11-12m x 120m), then yes, 09X probably would be a similar displacement to the Type-095.
If it uses the same powerplant as a Type-095, then the 09X would have a higher [noisy speed].

The sailless design and narrower beam should also result in a quieter submarine and also a higher [silent speed]. The narrower beam wouldn't be an issue if this was specialised for undersea warfare, rather than making compromises to carry larger numbers of VLS cells.

I'm reminded of how the Type-095 has a flat nose, so it can fit in more VLS cells. But this does come at the cost of speed and noise.

So perhaps the Type-095 is envisioned as a low-risk general purpose submarine, whilst the 09X is higher-risk design, focusing on undersea warfare.

Current reasonable rumors for the JN hull are:

- Special mission submarine
- SSGN
- Next generation SSN demonstrator

Also estimates for beam has been revised upward toward 11-12m with a length of ~120m which does give a reasonable L/D ratio of ~10 which is on the higher end of the optimal range of 8-10 but should nevertheless give pretty optimal hydrodynamic performance especially considering that there is no sail. Xiyazhou does bring up an interesting point about this submarine where suggests that this ship could be a next generation demonstrator using 09V level technology (Which are basically SOTA, especially the propulsion system) but a radically new overall design and layout.

The latest episode of Chahuahui also talked in length about the radical-ness of this new design, they suggested by removing the sail, the bridge could now be placed basically anywhere instead of directly under the sail like a typical submarine, this also means the entire frontal section of the ship's layout could also be rearrange for optimal efficiency. Being sailless also does present some unique challenges like having nowhere for crew to exit when out of port (Which probably means nowhere to smoke, apparently this is a big deal for crew) and there isn't anywhere for the crew to go when pulling into port and would likely need some pretty novel solutions like drones etc to guide the submarine in port or some kind of automated system. Though they didn't really go into depth about the actual purpose of the submarine but did mention that such large deviation from the norm could suggest some extreme performance requirements.

Hull sections on Google Maps near Northern JN submarine hall.

Doesn't fit either 093B or 095.

I think the new boat at Huludao is either 095 or 093B. We haven't seen any 10-11m hull sections at Huludao and I measured the new boat to ~110m on Copernicus.

OTOH I can only find 10-11m sections at JN. I think this new class is specific to JN. Assembly hall is ~325m x 55m with 2 rail sets = 4 120m x 11m hulls comfortably. Maybe 2 subs per year possible?

Mostly 9m and a few 12m hull sections at Huludao suggests continiuing 093B production + lower rate 095 for now, perhaps with 096 starting (1 per bay) in East hall.

This dome seems abit larger, seems to be the pressure hull end1780578068512.png
But unfortunately this does suggest the design being double hulled
