This appears to be a photo of a New Yuan Submarine. It's been kind of interesting, because we haven't seen much of Yuan after the 2nd block (which was about 3 units) were launched pretty close together from late 2007 to early 2008. Anyhow, here is a new Yuan (probably the 5th) that seems to have a little difference from previous Yuans.
The ones below are the photos of the 4th unit of 054A from HuangPu shipyard. I'm actually kind of impressed by how fast this one is progressing, because the 3rd one only got launched a few month ago. In fact, the 3rd one just started its sea trials and the 3rd one from HD shipyard still has a couple of months to go before starting sea trials. The other piece of news with regard to 054A is that the 054A ship that went to patrol pirate is now sailing to Pakistan. I think this could be part of the sales pitch to the Pakistani Navy. Anyhow, where are the pictures:
