I can't help but feel that sensor mast or whatever it is at the bow increases the sub's acoustic level even if a little bit. I think they managed to eliminate that thing with the 093B, or am I wrong?

Maybe... but by ex all British classes in service have and are silencious the main problem with Chinese classes as Soviet/Russians* especialy with double hull have many holes to fill or empty very big ballast btw 2 hulls, Western classes have much more small ballasts in general one in front and one in rear.

* Ex : Akula submerged displacement superior to 1/3 % than surfaced displ, Typhoon the double ! A US SSN about 10 % of difference.

For hydrodynamic these very numerous holes are bad also the missiles compartment for SSBNs Delta, Xia, Jin .. which exceeds after reactors etc... but impossible know exactly fot that, only visible elts obviously.

With apologies if I have asked this question in the wrong place. The appendage on the aft edge of the sail on the Song Class boats. Is it a sort of Wave-Form Exhaust as found on the Dutch Walrus and Italian Sauro Class submarines?

ThanksType 039 Song G1 - 000a.jpg

These are elements for hydrodynamics but no Walrus don't have it and her look unique, Sauro more close but different

The Song have replaced mainly Ming/035 and Roméo/033, he have a double hull ? as Yuan normaly based on or very close of the Kilo.

Song class

Thank you sir for your reply and link. I remain confused though, I doubt that the device is purely hydrodynamic, although there will obviously be a connection from water flow interaction with the diving planes in certain aspects.

The Walrus exhaust is of course unique, as one might expect.

The Sauro exhaust, I agree does look more like the Song appendage.

If we look closely at the openings on the side of the Sauro exhaust, they do look similar to openings on the side of the Song's 'thing'. (enlarge and compare them). Also, in the photo in my original post, there appear to be holes or slots on the upper surface of the 'thing' which lead me to wonder why they are there.

Curious eh?

(I don't know how to attach photos in with the text yet)

It may be a device to increase the vertical stability of the sail underwater (i.e. to reduce chance of roll), given how tall the Song's sail is compared to most submarines.

A new Yuan normaly 039B on this new pic to Jiangnan ( Shangai ) the 4th in construction with 3 others to Wuan pic yet posted in 12/2016 these 3 are visible now on GE ( 01/2017 ) the 4th is not visible on GE.

According the chart i post again completed this new is the N° 346 the 17th Yuan, yet 13 in service ( 9 build to Wuhan + 4 Jiangnan ) with these news there are enough for replaced the last Ming, 3, to Lüshun's Flotilla
In the past yet 3 Yuan was put in service in a year, 2013 and possible see 3 in GE in 2010.

It is interesting to see the old sailor coming back to their old haunt I guess they can look back with pride even if type 91 is primitive But hey see how far Chinese navy has improved over the year it is nothing short of phenomenal

Published on Apr 24, 2017
China's first nuclear submarine, which was decommissioned after more than 40 years of military service, went on display to the public on Sunday on the 68th anniversary of the establishment of the PLA (Chinese People's Liberation Army) Navy.

A launch ceremony was held in the Chinese Navy Museum in Qingdao, a port city in east China's Shandong province, where the nuclear-powered submarine is berthed.

Several veterans like its first torpedo officer Wang Jikun were invited to the ceremony and were happy to re-board the submarine and rekindle old memories.

"I feel very excited to come back to the place where I worked and studied," said Wang.

Other visitors were impressed by the submarine, which has been seen as a strong symbol of China's Navy.

"Being a Chinese citizen, I feel at ease because such as strong navy is protecting us," said Fan Baoyue, a visitor from central China's Henan Province,

The submarine, named the Long March No. 1, was launched in 1970. It was commissioned to the PLA Navy in 1974.

After undergoing a thorough denuclearization process, the submarine was towed to a wharf belonging to the Chinese Navy Museum in October 2016.
