Recently, I just got some new photo of ships that are under construction in WuChang shipyard. If you guys don't already know, many of the new submarines and cutters are produced here.
It looks like most of what WuChang had on order for China Maritime Surveillance (CMS) have already been delivered. Most recently, Haijian-50, which is the largest cutter on order at over 3000 tonnes, was launched. The only other CMS cutter that is this size is Haijian-83. That was delivered as part of the last 5 year plan. In case you are wondering, CMS places orders for cutters at the start of a 5 year plan (the current one of 2011-2015 is the 12th). They will send RFPs to different shipyards in the country, who then respond with their design and pricing. Once the selection is done, you will start to see them getting built in the shipyards. That's why we generally don't see CMS cutters getting built until around the end of the 5 year plan. Here are some of its photos:
There has been some articles like this this week about Pakistan acquiring Chinese conventional submarines. I don't think it's official, but such talks have been going on for the past couple of years. I think that if it does happen, it will be for the Yuan class submarines that are currently under mass production. They won't be as quiet as the Western options, but they do satisfy the AIP requirement. At the same time, they have much improved combat system and sonars compared to previous Chinese submarines. Here are some of the photos of the most recent variant of Yuan:
