China has became the beggest submarine makker in this earth. The Yuan Class also is the biggest deisel-electronic power submarine, displacement of this class has reached 4000 ton! None sub being service can be rival of it.
4 has entried service meanwhile another 4 are building, nobody know how many it will be built.
The aimed target those powerful sub at obviously is US carrier. Ive been wonderring are there any comparable sub with it?

Nice pics emile

Yeah, it's very big for an SSK.

I am guessing that reflects a Chinese need for an SSK with greater combat endurance, that can conduct operations further from it's long coastline, out to the first and second island chains.

I have heard rumors that this class, in addition to being fitted with the same diesels as the German U212 class, may also be fitted with an indigenous air independent propulsion system.

Any descriptions of the details called out in the photos available?

Very interesting.

In terms of size at least the Australian Collins class would be the closest. And given the Collins long endurance, weapon load, sensors and very quiet operation, probably more deadly. However there are no current plans (publicly at least) to fit the Collins with an AIP so this could be seen as a small achilles heel in the design.

Sorry, I was wrongly call these as "YUAN" but that is "SONG" class with some provement. Designation of SONG "宋" is 039, whereas YUAN"元" is 040.

Yes, displacement of SONG is similar to Collins class, but that 040 YUAN will be the biggest desiel-electric submarine being this time.

The submarine photos...and the details circled in red....I will try to identify some details for the readers here.

THe three white horizontal lines across the turtle back or artifical combing on the top of the boat...these appear to be identify locations where a tug boat would locate lines for towing or tying off the boat to a pier.

The three plexiglass or glass windows on the forward end of the sail are just that windows. Most boats have a couple of hatchs at the hull level inside the sail and one higher up which gives access to the sail. IF you look closely you will see on top the sail a glass or plexiglass windscreen temporarily mounted on top the sail. This is a common attachment to boats for navigating in bad weather. This also indicates the possiblity of cut outs inside the sail for movement foreward and aft in the sail and up and down into the boat.

Most Sail structures will have various antennas and or masts which will telescope up and down and fitting flush with the hull when retracted. The two small round domes sticking up in the sail about a foot in height appear to be the tops of periscopes. They are in the correct location for this as usually you do not mount a periscope way aft in a sail structure but foreward and they must be able to rise above any other masts in the full up position.

The mast you see...raised above the sail structure aft is usually a snorkel mast. This allows air to be sucked into the boat for ventelation and also to run the diesel generator when in port to charge the batteries. A cycle often repeated with regularity when keeping current ready status to put to sea. These things must be maintained ready to put to sea...meaning battery charges regularly scheduled and also fresh air taken in ..not only for breathing/ventellating but the high pressure air banks need to be regularly charged as well. Also Necessary for ready status to put to sea.

The two rows of horizontal holes aft of the sail appear to be diesel exhaust ports...where the diesel exhaust is vented overboard.

The little white contraption just below these two rows of holes appears to be a temporary connection..this is often where a ships flag is mounted while in port..the ensign or such..skippers flag or such.
This is also about where on some boats a trailing wire antenna is located.

The little green canvas box hut on the bow of the boat is obviously temporary and covers the foreward access hatch. most likely down to the torpedo room or first level. Boats often have removable deck plates on the first level leading to access below this hatch to the torpedo rooms.

The little hole on the side of the sail. Not sure what it is..but it appears to be for flooding or overboard discharge of water...during some kind of operating evolution. It could also be for access of some kind of operating deck wrench.

The long series of holes down the side of the boat are flooding/venting holes. The top of the boat you see is not the hull itself but a flooded fairing called a turtleback. It is a type of shell and hence the name turtleback. Often certain kinds of equipment are mounted above the hull and inside the turtle back. The holes allow water to effeciently flood this turtle back. On the U212 type boats this is often a long slot running down the length of the boat..instead of holes as is done in these photos.

Look at the bow at the torpedo tubes. Notice how close in proximity the tubes are mounted at the bow. This also means the tubes are this close in the torpedo rooms themselves. This is also a strong indicator that there is not much automation in the torpedo rooms. By this I mean hydraulic power for moving weapons around and into and out of the tubes. This most likely and meaning the weapons are manually moved around the room. Block and tackle...pullys etc etc.

This is not a new photo..Ive seen it before. it is at least a couple of years olde.

Just thought some of you would like to know some of what can be seen in the photos.

Impressive but what is the use of having bigger electric subs when they have shorter submersible time ? If it were to come in contact with a nuclear sub then its electric engine might give it greater concealment but for shorter time. They would be fighting against the clock as well. Also even with a larger sub, the range would still be limited due to the need to refuel.

It will however give them better defensive capabilities but it wont be enough to protect their sea lanes.
