13.5m is realistic. 14m implies 26,000 tons fully displaced...

I think it is reasonable to expect 12-13+ meter-diameter submarine hull, with 14 meters being the upper limit.
In the meantime, I suppose it also depends on whether the 095 SSN and 096 SSBN shares the same basic hull diameter design.
Also @Kalec welcole back!
How did you come to that implication?

type 094 itself is 135 meters lengthy with double hull configuration and 12.5 meters beam.
what we have seen in research papers and hull diameter on satellite image.. type 096 will be considerable bigger than type 094 to accommodate bigger SLBMs.. this is very much reasonable and down the line development process. from 092 to 094 now 096.
I was talking about 095, not a SLBM carrier. And it's not as if I'm projecting it to be 16 thousand, I've no idea what the displacement will be in reality. But IF a sub, any sub, is 14 m in diameter and is around 130 something meters long, then a submerged displacement of approximately 16 thousand tons is likely.
It seems likely that 096 will also be significantly longer than the 094, seeing that basically all comptempory SSBNs are around 150-170Ms long.
i am expecting the same length of type 096.. in between 150-170 meters.
14 m hull diameter, assuming single hull, and L/D of say 10 (ideal is 7 but no one is building that kind as far as i know 9-10 seems to be more common and that doesnt really add much drag) Means about 140 m in Length.
Submarine roughly have 3 kinds of "displacement" namely Surfaced which basically shows Pressure hull volume, Submerged which Surfaced+Ballast tank volume or ROB (Reserve of Buoyancy) and Envelope volume, which is Submerged + water in Free Flooding section.
If one read Capt Jackson's lecture of Submarine design. There is bit more into that :
NSC or Normal Surface Condition is basically the weight of the fixed equipment, structure etc in the submarine including variable ballast, consumables etc which to keep crew alive and submarine in equilibrium position.
Standard displacement is NSC+Fixed ballast. Fixed ballast or known as "Lead mine" is as name suggest lead blocks used to balance the volume provided by the pressure hull (Principles of flotation you want to keep the density of your sub = water, too low and you float, too heavy, you sink)
Submerged and envelope is basically what i described above.
14 x 130 m dimension provides about 21551 Cubic meter of volume. That is approximate for your Envelope displacement. As for the submerged displacement This typically 93% of the envelope, so 21551*0.93 = 20042 metric tonne Submerged.
Now what is Chinese consideration for ROB (Reserve of Buoyancy) ?. Which directly dictates the volume of the MBT (Main Ballast Tank) Historically Western powers e.g US have lowered the "standard" for ROB, Nowadays it's typically 10 % or less. Russians always go big due to their fear of mines about 32% and for Typhoon as they desire icebreaking capability, 48%.
If Russian consideration is taken then the MBT volume would be 20042*.32 = 6413 cubic meter. Thus leaving the Pressure hull volume which ideally should be same as the weight 20042-6413 = 13628 metric tonne for Surfaced displacement. If US/Western consideration is taken then the Surfaced displacement would be about 18000 metric tonne.
