It is more correct to say that specifically US subs have their torpedo tubes at the flanks canting outwards due to the presence of the spherical bow passive array, which I'm not sure either the British or French navies even have. All nuke subs do have a smaller cylindrical active/passive array, which allows the placement of the torpedo tubes either on top (Russian/Chinese), or on the bottom (British/French/US). Though in the case of the US its subs have both spherical arrays and cylindrical bow "chin" arrays on some subs and not on others. IIRC correctly LA and early block Virginias do not have chin arrays, while Seawolf and later block Virginias do have both spherical and chin arrays. As for the differences in placement, it really makes no difference since there is only a minimal vertical component to these arrays' detection envelopes as they are mostly cylindrical +/- some minimal spherical tendencies, meaning placing them above or below the torpedo tubes isn't going to make a difference in how well they detect either ships or subs.

Yasen seem to have a similar arrangement to the Seawolf and Virginia but there are no actual images of that area, only illustrations. The Astute class has its torpedo tubes at the bottom and furthur back but I don't think it has a spherical sonar. But the Brits claim they have the best sonar system in the world (Sonar 2076).

Another high-resolution magazine scan from the recent naval review. Two iterations sailing side by side...

Is there type 95 thread? Anyway important news. As I said before Sichaun is now the main lab and industry for high end armament and nuclear weapon.
They said that type 95 has entered service in Nov 2017

Mysterious Sichuan base spawns new reactor for PLA vessels
Base 909, said to be located somewhere in Sichuan's Jiajiang county, was initially set up for "hydroelectric development" purposes
By ASIA TIMES STAFF JUNE 28, 2018 4:39 PM (UTC+8)
A research facility in a reclusive backwater deep in the rugged mountains in the western Chinese province of Sichuan may be the birthplace of a miniaturized nuclear reactor series that could propel the PLA’s new submarines and its future carriers.

Shrouded in secrecy, Base 909, said to be located somewhere in Sichuan’s Jiajiang county, was initially set up for “hydroelectric development” purposes. In past decades it has conducted vital nuclear research and development for the Chinese military. Among its results were the power plant for the Type 092 submarine, China’s first nuclear-powered ballistic missile submarine that entered service in 1987.

A news program aired by state broadcaster China Central Television earlier this year shed more light on Base 909’s latest research achievements.

The program contained a brief close-up of a new variant of China’s third generation Hualong-1 pressurized water reactors. Known as the HPR1000, the reactors were previously applied only to commercial power generation.

Researchers at Base 909 have reportedly developed and trialed a land-based, compact version of the Hualong-1 reactor containing 177 fuel rods. The new reactor was subsequently installed in the latest Type 095 assault submarine. The first completed vessel entered service last November, and several more are said to be under construction.

Taipei Times analysts once noted that Type 095 submarines could potentially act as undersea escorts for PLA aircraft carrier task forces.

Two state-owned reactor builders, the Beijing-based China National Nuclear Corp and China General Nuclear Corp in Shenzhen, were ordered to merge their third-generation designs to create the Hualong-1 in an effort to explore commercial and military uses for the reactor.

Ship-borne reactors have to undergo meticulous land-based tests and troubleshooting trials to achieve absolute reliability before they can obtain certification to propel submarines and other vessels.

Sina Military also reported that there could be several other ship-borne reactor prototypes undergoing land-based trials at Base 909, adding that researchers would have to strike a careful balance between reducing a reactor’s physical size and maintaining its power output.

The report speculates that a new reactor developed to generate propulsion and electricity for China’s future nuclear carrier could well be based on the home made Hualong-1 model.

With all these revisions I wonder if it makes any sense to treat the latest and earliest versions of the 093 as the same class of subs. When we look back at its history it feels a lot like 093 has been more of a test platform used for refining design and technologies not unlike what we saw with the multiple iterations of the 052s, 051s, and 053s.
Not true in more test and platform never see it ! i don't know what you read...
093/Shang family all as Los Angeles variants I - III or even Victor I -III use same base only capacities vary or a little lengthened etc...
