Last, new infos,
Now almost sure the 413, only 093A without VLS is in service from 2015 launched in 12/2012.
Seems 414 the first new 093B with VLS in service and 415 - 418 in construction maybe the 4 in service for 2019/20 one by year about.
New definitely replacing 091 so a fleet of 8 SSNs now 5.
093 : 407, 408
094 : 409 - 412
With these last infos which confirm i have posted before we can considered !
Deployment
NSF, Shakizou/Jiangezhuang close Qingdao, 1st Submarine Base
Sure
3 x 091
Almost sure the first 093B, 414 Henri K say the pic from there, remains possible he have moved after for Yalong Bay ?
SSF, Yalong Bay close Sanya, 2nd Submarine Base
Sure
2 x 093 + 4 x 094
And make sense the 093A, no pics, based there do same SSN number as NSF, in more very important used for escort SSBNs in the SCS bastion and considering it soon a 093B.
SCS bastion remains not ideal for detection coz except in the center around much coastal, shallow water and 094 yet enough noisy as all nuclear submarines are less discret in these areas.

Construction :
Considering the 413, 093A launched in 12/2012 normaly and 414, 1st 093B in service in 2016 presumably... in this case lauched in 2013,
With these 2 facts we can consider actualy they build one SSN by year after a break brtween 2007 - 2012, new since 2012.
