The issue you are referring to has been discussed by very knowledgeable people here on SD, who had contact with sources within the ASW community of the US Navy at great length.ACP 100 event was on June 2010 or 66 months ago.
Just think --- what kind Technological breakthroughs, Noise reductions, Weight reductions, Vibration reductions, and miniaturization developments have occurred since 5.5 years ago ??
Will these Nuclear Propulsion manufacturing tech knowledge be applicable to 093xx sub, 095xx sub, and 096xx sub ??

Who did really track the Ronald Reagan carrier + the USN escort GROUP for at least 12 hours in the Sea of Japan ??
All joking aside...it was not at all what many in the press and elsewhere have tried to make of it.
Here's a hint however...no sub surfaces unannounced near an OPFOR to show off. They let later revelations/announcements (usually with some kind of proof) show what they did. The most important quality for any sub is its stealth and cloak of invisibility.
Surfacing usually occurs for only two reasons...one if related to the sub itself, the other is related to its opposition.
But that incident with the Reagan is now old history and people are going to just have to believe whatever they will of it. Best to let it drop.

To be sure, let's not go into that incident any further. No more posts regarding it because it will only lead to dissention.

As it is, the Type 093 is a fairly well known quantity which we have also discussed.
The Type 095 is not so. There are rumors that at least one has been launched, but no verified pictures of it, or true sense of its capabilities exist.
Given where the Chinese were able to get with on the Type 093, I would expect that the PLAN may be approaching the quieting capabilities of the LA Class, perhaps even the ADCAP LA Class.
That would be fairly extroridnary given their development cycle to date...but I would not doubt it.
We will have to wait however to really know for sure.
