as you seem to exude.The 091 is far more likely to be acoustically similar to the Skate class as both it and the 091 are both first generation SSN designs. I have no idea why you think PLAN somehow was somehow able to skip a generation to gain on the US especially since they had to start from scratch with no help from the Soviets. Maybe you think the 091 is equivalent to the Skipjack just because they both had teardrop hulls? You should know that noise has far more to do with internals than hydrodynamics, and the Han's internals are all first generation, like the Skate. ONI has put out a more recent report on the 093 which places it worse than Victor III in noise. Even if you assume the report is referring to late model Victor III's, that still makes it worse than the Sturgeon, which is quieter than late Victor III's. As for 093G, it depends on why its predecessor the 093 is noisy to begin with. There is only so much you can improve on a given design, so there is so much noise reduction you can achieve. If 093 started out worse than Sturgeon, I see no reason to believe that 093G could achieve better acoustic levels than early 688 class subs. Assuming that the 095 is not the same boat as the 093G and is a new class altogether, I think the 095 could reach 688 or even 688i levels of quietness, but that still places the 095 more than a full generation and 30 years behind the US in nuclear sub technology. IMO the best-case scenario is that it will take a new 097 class for China to more or less catch up to the US or at least field a near-peer competitor to the Seawolf/Virginia, sometime around 2030. But given that the Virginia is scheduled to be built through 2043, and that newer generation subs will have a much harder time getting quieter and will be developed with more and more money and effort spent with less and less return in acoustics reduction, this is not as bad as it seems.

the diesel generators for example are german based, the sonars are french and russian derived, the fire control is french derived, the torpedoes are based off american tech, all of which are used on the Yuan SSKs, which are a match for anything the Japanese have short of the Soryuu's and are the same systems used on the PLAN SSNs. The only major limitation is the nuclear vessel itself noisewise, but Chinese designs have always used turboelectric systems like the french SSNs, which mitigates machinery noise generation compared to geared systems of a given generation. They have their own drawbacks such as power density and size, but in any case the Type 091's systems place it closer to the Skipjack than the Skate technology wise, and the PLAN SSNs in general are closing any tech limitations faster than the Soviets did.

days, but certainly back in the days of the 091 and even 093 it's fairly safe to assume that they were several decades behind USN's state of the art and falling further behind until very recently. But even with the rapidly advancing state of Chinese science and technology in general, I doubt we will see a truly equal peer to peer comparison until the Type 099 vs whatever comes after the Virginia in the decade of the 2040's. This is assuming the PLAN comes out with a new generation every 10-15 years or so until then. I suspect the 097 will only be a "near-peer" to the Seawolf/Virginia (much like the Severodvinsk/Yasen class) and will debut ~30 years after the arrival of the Seawolf in 1997.
