Type 209 (Germany)
some sourches claims "Yuan" class subs equipped with air-independent propulsion system.is it?
Yuan, 093a/b type, fuel cells AIP, only 4 subs this type. The first one was finished in 2004. the 2nd,the 3rd and the 4th were all finished in 2008.
it was developed form PLAN's 093 type sub ,they have the same inner shell. Yuan type absorbed the design experiences of the silence submarine form Russia, but it has more advanced manufacture technology than Russian original.
093a/b(Yuan) has been ceased now, For next "goal" sub type (A type that will be manufactured,and be widely equipped).
fuel cells AIP is not the newest tec to China, all types sub that made after 2005 have that,any type.
The topic is "NON-AIP diesel submarine", it's not necessary to put it in your poll.
those pictures show 8 submarines that serviced in one of sub-fleets of PLAN. For keeping military secret, the pics was erasured some background. There are 3 Yuan (093a/b),4 kilo and 1 Song (093 type).

i heard the kilo is one of the quietest hunter killer subs in the world at present....
During an exercise off of Southern California, my last ship, the USS Momsen was able to find and keep the HMS Gotland (Swedish AIP submarine) from attacking the surface ships.. was it hard, yes, but not impossible with modern active sonar..
also, the modern US nuclear submarines are INCREDIBLY quiet.. I'd say as quiet or more so than a modern diesel.. (the technology that went into the pumpjet propulsor and other stuff that makes noise is incredible)

So, exactly how many months/years did it take you to find that sub?
I can think of any number of current conventional subs that are acoustically quieter than it - and quite frankly, it was leased for a number of other reasons. - and it was found and killed a number of times (as have nukes, as have other conventionals). the contact and training parameters are restricted for a number of reasons - it was not "free range".
IMO the USN would have been better served leasing the Danish squadron (available if they'd asked the right people at the right time) as it would have tested fleet contact and pack issues. The Swedish lease was for a limited requirements test and was related to other issues way beyond "smell sub, hunt sub, kill sub"
If true (and I would think its journalistic enthusiasm) its a tragically oversimplification of what, why and how it was leased.
are they a good sub? of course. was the result such a simple outcome? no
in fact, to even remotely pass comment on the results without knowing the training vectors is absolutely foolish. It is a variation of the Cope India commentary that first came out
Or they could have gotten half a dozen U206A from Germany for pack tactics training just a few years ago (by now those're all released to the scrappers afaik).
As for "best non-aip sub"? Depends on the threat it's facing of course, and the environment. Facing a ASW group with full sensors in a littoral scenario, i'd - in comparison - put my money on a system that is available to its navy in sufficient numbers and that carries a long-range cable-guided torpedo system with swarm attack capability and soft launch. That would be the Turkish U209 Atalays armed with DM2A4.
Has Mk48 Mod 7 been fully integrated and deployed with the Collins yet btw?
