Pakistan to acquire six submarines from China

[applesauce]

can anybody please definitively tell me that what are we buying??....type 39 song or type 41 yuan....because china itself has only 7 yuan class....and we are buying at least 5 or 6!!

you know if pakistan buys six they arnt gonna send them from plan stock... it doesnt matter how many china has its how many china can build and how quickly

 

[Jango]

but surely the chinese have more requirment than pakistan...thats what i meant.

As the next generation of Chinese SSG, the first boat of this class (330? Type 039A) was launched on May 31, 2004 at Wuhan Shipyard. Its design appears to have drawn some features from both 039G and Kilo. The submarine has a 039G style sail with diving planes. However a raised "hump" on top of the teardrop shaped hull clearly suggests a Kilo influence. Its displacement has been estimated to be 3,600t dived. In addition to a diesel engine, an AIP system based on Stirling engine technology is thought to have been fitted to extend its endurance while being submerged. Integrated with advanced noise reduction techniques including anechoic tiles, passive/active noise reduction, asymmetrical seven-blade skewed propeller, 039A is expected to be as quiet as other modern diesel/electric powered submarines therefore much difficult to be tracked. Like 039G, 039A is also capable of launching YJ-82 AShMs, besides 533mm wire-guided torpedos (Yu-6) from 6 forward tubes at the stern. The emergence of 039A in such a short period of time after the starting of series production of Song class SSG came to a surprise to the US intelligence community and a Yuan designation was quickly assigned by the Pentagon. Together with Type 093, Song and Kilo class submaines, Yuan class could pose a credible force to counter US and Taiwanese naval forces. The first 039A completed the sea trial in 2005. The delay in the construction of the 2nd Yuan class suggested that the design had suffered certain technical problems. The construction of Yuan class resumed probably in 2006 and two boats were built in 2007. The second boat (331?) compeleted her sea trial and entered the service. This new boat has been installed with flank sonar arrays. The third boat was seen arriving in Shanghai in May 2008. The latest images (December 2010) indicated that the 4th & 5th 039As were just launched alongside a further improved design (Type 039B?) at Wuhan Shipyard (see Below)

Improved Yuan
-------------

The first boat of a much improved Yuan class (Type 039B?) was just launched at Wuhan Shipyard on September 9, 2010. This class has been speculated to feature a new sonar system (flank sonar arrays?), a new surveillance and targeting system (periscope, radar etc.), and a new weapon system (possibly long-range AshM launched from torpedo tubes). The submarine also adopts some advance features learned from the Russian 636 class design, such as the hull mounted retractable foreplanes. The sail appears wider but more hydrodynamically streamlined and stretched compared to that of 039A which might house a short-range SAM system for self-protection against slow-moving ASW aircraft. Its submerged displayment might have been increased to 4,200t. As the result its noise level is expected to have been further reduced. However there is no indication that 039B carries a towed array sonar. The overall performance of the improved Yuan (may be assigned a new class name by the west in the future) is thought to be comparable to the latest Japanese Soryu class SSG.

Pakistan also needs to start manufacturing midget and smaller submarines. Technical know how from operating and manufacturing of Western submarines should be put to the table for local prototypes. Iran also has manufactured smaller submarines and we can also approach them for joint ventures.

these are pakistans war babies!!!

They are Pakistan's guardians

Yep it is unlikely for China to Send Pakistan old stock. It would be built to Pakistan's specification. It will also be part from China and part built in Pakistan. This allows for technological transfer just like what happened with the F-22P frigates.

I think it would be useful to think in terms of JFT, when we think of this project - Yuan is a departure point, not destination.

 

[khurasaan1]

ok...soundz kool...about this joint venture....nice collaboration...

 

[SBD-3]

I dont think its a ToPT. The news that i went through a while ago was that China would be building most of these subs in China and later subs (2?) would be assembled in Pakistan to allow PN engneers to gether knowhow. Btw PN's requirments and budget doesnt allow for continued induction as PLAN. So there is little need for ToPT since Subs are not inducted every month.

Improved Yuan update...

The first boat of a much improved Yuan class (Type 039B?) was launched at Wuhan Shipyard on September 9, 2010. This class was speculated to feature a new sonar system (flank sonar arrays?), a new surveillance and targeting system (periscope, radar etc.), and a new weapon system (possibly long-range AshM launched from torpedo tubes). However there is no indication that it carries a towed array sonar. The submarine also borrows some experience learned from the Russian Type 636 design, such as the hull mounted retractable foreplanes. The most noticeable feature is a new sail which appears larger in length and width as well as more hydrodynamically streamlined compared to that of 039A. As indicated by a detachable compartment in the mid-section of the sail, it may house an integrated submarine escape system. One image suggests there is a bulge at the bottom of the boat in the mid-section. Spectulations were that it could house a single SLBM launch tube extending from the bulge all the way to the top of the sail, a design similar to Russian Golf class SSB. Therefore this particular boat has been speculated to be an SLBM experiment submarine to replace the vintage Golf class SSB still in service with PLAN. As the result its submerged displayment may have been increased to 4,200t. However this theory may turn out to be false if additional boats are built in the future. The improved Yuan class (may be assigned a new class name by the west in the future) sailed to a naval base in Shanghai in May 2011 is currently awaiting for its sea trial.

Yuan is likely to be inducted before IN Scorpene, will prove advantageous for PN as it will be operating two versions of AIP equipped subs. Specifications were sent to China a while ago and PN version (type 41 as they call it) should be more capable than Scorpene on paper at least, already a generation ahead of Agosta-90bs. One of the requirements is 650 mm missile tubes in order to launch CMs!

guys , you might find this thread interesting

 

[lem34]

Dont know much about subs but I think Pakistan should have subs lots of them and is it possible they could carry some nukes that would be cool too.

 

[TOPGUN]

I sure hope we get these given the current saga in the nation who knows..

 

[maverick1977]

There are a lot of pages to go over, briefly, anyone, couple of questions..

1) When was the order placed? total cost and if ToT, how many will be build in China and how many in Pakistan
2) specifications, like torpedo types? sonar, and electro spectrum analyzer which looks for magnetic waves, tube types, 533 and 633? ow many torpedos, how many CM's, total crew members? endurance and range and total depth.
3) delivery dates?
