These depictions of the "Type 095A" SSN are from the "Warship Knowledge" magazine, which is supposedly a reputable source with direct ties to the China Shipbuilding Engineering Society. This would be, if the aforementioned are valid, the first official admittance of the Type 095's existence.

And if I'm not mistaken for You a similar event as for me the unveiling of a new J-20 LRIP-bird !?

Well, the J-20 has flown while we don't even know if the 095 has been built, or even exists.

And I thought Germans were more into u-boot stuff than flugzeuge?

This recent sketch is identical to an older artwork. I am wondering whether this is a deliberate leak similar to the 2007 J-20 leak which turned out to be pretty close to the final thing:

It's also possible the CGI is merely a placeholder. The description may be influenced by insider information, nevertheless.

Here is a randomish question, but why do modern Subs still need sails?

Nothing the sail is used for, or contained in the sail could not be brought into the hull and/or substituted by modern technology.

The periscope and other sensors is already extendable, just compress it more by bring the entire length to within the main pressure hull.

Dive planes can be moved to be hull mounted.

For surface navigation, you can use the periscope or a new, seperate specialist sensor array to give you a better view and perspective compared to sitting on the sail. You can even have an erectable mini-bird nest observation platform if you really must have a human being sit that high up.

The only thing the sail could be used for, which would be hard to do without, is ice breaking for arctic operations. But that is such a fringe activity as to be largely irrelevant as far as Chinese subs are concerned.

Am I missing some vital function of the sail that subs cannot do without?

By removing your sail, you are going to massively reduce drag and flow noise, especially at higher speeds. Just the act of removing the sail will increase all speed ranges of the sub by a fair margin.

The newer, simplified shape could also mean the structural integrity of the sub is improved, increasing dive depth.

So, the obvious question is, why hasn't anyone tried to do away with it altogether?

Like a cuttle-fish or squid?

Space within the hull is precious. Anything that can be left outside is left outside. Also, one more hole made in the hull is one more incident waiting to happen.

The periscope and other sensors is already extendable, just compress it more by bring the entire length to within the main pressure hull.

If by extendable you mean telescopic, then no, not really. The masts are typically one piece.

Dive planes can be moved to be hull mounted.

Nothing beats Mk. I eye balls when it comes to situation awareness.

You can even have an erectable mini-bird nest observation platform if you really must have a human being sit that high up.

Consider a situation of a non-calm sea state. It would be a bad idea to open a hatch so close to the water when waves are crashing onto the hull. Within the sail, there is another hatch, which is protected from the elements by the sail itself.

Stability. If you have not noticed already, many marine animals have a fin.

The newer, simplified shape could also mean the structural integrity of the sub is improved, increasing dive depth.

There isn't going to be an increase of structural integrity if one has to cut many holes on the hull to fit what previously resided in the sail.
