Been checking out the imagery of Huludao shipyard - the amount of dredging around that place since 2007 is breathtaking. They've landfilled over 4 square km of sea near the shipyard.

Main points :


By analyzing several articles published two years ago on a LIU Chun Lin, deputy chief engineer of the Institute 719 which is the cradle and the engineering of all Chinese nuclear submarines, we learn that the project a new class of nuclear submarines was launched in 2012.

It should, according to a document released in 2013 by the CSIC group meet several tactical objectives as "high speed, multiple payloads, high sensing distance, and full stealth."

The new class would benefit, again according to the same document, a new nuclear reactor primary circuit with natural circulation high, a single hull pressurized mixed / dual, vertical launch system and the possibility of integrating payloads additional outside of the hull.

Using the same lifecycle development of Type 09III cited above, and given that the Project Type 09V is launched in 2012, one might expect a construction start for this class submarines in 2017, the first set afloat in 2023 and admission to active service around 2025.

And that date from 2017 perfectly matches that of the inauguration of the new assembly line.

So you could say, safe to say that the 09V type will be the first class of nuclear submarines to be assembled in this new production.

Like the SNA and SSBNs projects in China always go together - it was the case of Type Type 09I and 09II, 09III then Type and Type 09IV- parallel construction one can also imagine the new SSBN 09VI in 2017 or 2018, but no official evidence to assert this point today.

I would disagree with Henri K.'s guesstimates on the start and service dates of 095 (09V, I know, but let's stick with the more familiar designation). His arguments are largely based on the start and service dates of 093, as well as the availability of the new pressure halls (2017).

First, 093 build process is not representative. There was a big gap between 091/092 and the restart of 093 program (nearly three five-year plans due to budget cuts and priority changes). They had lost a lot of personnel and experiences due to that hiatus. In addition, there weren't adequate R&D in between.

Second, the construction of the new facilities, not just the pressure-halls, but also others including the final assembly dock, does not necessarily indicate the start of the new 095. It's more indicative of the potentially _serial_ production of new SSN's and SSBN's. They could well start the first 095 in the existing facility. 095 program was officially approved in 2012 and, in 2014 governor of Liaoning province, the former CEO of CSSC, said publicly that China has completed the design of the "4th generation" of nuclear submarine. It is reasonable to expect that the first 095 will be constructed and even enter service before 2020.

Finally, I'm not sure about Henri K.'s assertion that 095 and 096 would be built in parallel, as China appeared to always parallel construct SSN and SSBN of the same generation, based on the experiences of 091/092 and 093/094. 091 & 092 took so long, they're more experimentation to me. 093 & 094 are also a more struggling experience for China. Their experiences can't be used as the standard process. 095 & 096, on the other hand, will be the generation of nuclear submarines for China to be serially produced much like 052D for destroyer (hence the new facilities). I believe 096 will take more time and comes later. China will also need to develop the JL-3 class missile. This is my personal opinion, of course.

Here is the latest GE image for the Bohai Shipyard new building halls under construction.

Huludao Shipyard.png

The red-framed building on top is the module assembly hall: area 6473 m^2, length 86.6 m, width 74.6 m.
The green-framed building in the middle is the final assembly hall: area 40260 m^2, length 288 m, width 135 m.
The blue-framed building at the bottom is the pressure hull building: area 35446.48 m^2, length 204.6 m, width 172.755 m.

The final assembly hall is still under construction and is scheduled to be completed in 2017. The other two buildings have completed construction.

Apparently, these buildings are constructed for batch production of new SSN's and SSBN's.
