055 DDG Large Destroyer Thread

[Blitzo]

A lot of the equipment are pretested in land sites --- like was there a pic of a place in the desert that had a lot of Type 346 panels mounted and being tested --- and there is a lot more confidence in shipbuilding. Since you already have six 055s (and maybe more if there are more dry dock space) that already shows a lot of confidence with the type, with a lot of testing and debugging on the individual components and systems done on test sites before they go into the ship.

There is something different about the 055 that you cannot compare to the 052D. There were only two 052D that were being built in 2011-2012. But there are SIX Type 055 spotted within a year, which in comparison, took a while before there were six Type 052D finished or in construction to appear.

The way to explain this is that there are now new procedures, and even simulations --- that is 'testing' the ship even before it was built for potential bugs and other issues. The quality control and testing is much more rigorous before all the components are assembled, before the systems are all installed.

I think considering the 052D production line was only at JNCX at the beginning, and that 055 production began when both JN and DL and been running with recent 052D production experience, it has more to do with simply new procedures and improved simulations, but also because the shipyards themselves were able to jump feet first into 055 production with both (namely DL in this case) having had built a number of 052Ds before moving to 055s.
Remember that in the years prior to 052D production beginning, only JNCX had produced destroyers for a while in the form of the last four 052Cs, allowing them to get to work onto 052D pretty smoothly with a relatively experienced workforce. At that time, DL's last destroyers built were the 051Cs.


... This isn't to say that QC and testing has not improved greatly from 052D to 055 (I would be surprised if it has not).

It isn't just building 052D ships. Note that JN are the ones that make all the 052x ships including the 052 and 052B from the beginning, while the 051 ships including 051B/C are made by Dalian. Jiangnan and Dalian have this North-South rivalry going on like the way Chengdu and Shenyang has on the airplane field. Both have also gained much ship building experience in the commercial field as China's shipbuilding industry moves from catering to the low, then middle, and then the high end while competing with traditional heavyweights in the shipmaking business in Europe, Korea, and Japan. That gave them the tools, the skillset and the infrastructure to perfect their science and their art to tackle increasingly higher end and more complex projects, right up to aircraft carriers.

We can't hold them to historical patterns because these guys have become very good at what they are doing and continually strive to do better.

Just shy of 70,000 tons of warships at DL with combined 544 VLS

Sorry my poor animations

3 x Type 052D in water
2 x Type 052D under build
3 x Type 055 under build

Either this, or perhaps a lot of the technologies have already been demonstrated on the Type 052D and more or less being re-used?

Personally I doubt if much can be tested by simulations - nothing is better than trying it out physically at sea, although I agree that there must have been lots of 4D/5D BIM analyses done for clash analyses / drafting maintenance manuals / simulation of replacing parts, etc... as compared with the Type 052D when such software simply hadn't been developed at that time.

The VLS, engines might still come from the 052D, but practically the radars don't. The Type 346 might be a new version, one using Gallium Nitride instead of Gallium Arsenide semiconductors on the elements. All the mechanical radars of the 052D are gone --- the Type 366, 364, 517 and 344, replaced by radars we have never seen before and introduced only with this ship. There appears to be a new ECM suite. No info on the sonar sets. The use of an integrated mast is a first for a Chinese warship.

So there are techs that had been previously demonstrated on the 052D, but there are also new ones.

looking good, 055 - designated 101 ...
some CG but rather realistic...
enjoy...

OUSTANDING 101 it is! I'll have to chnge the pennant on my model...I had 110...a simple fix to make.

 

[Tam]

For a Type 055 to get pennant 101 is sort of symbolic. 101 is the pennant for the first ever official PLAN destroyer. Lead member of the Anshan class, the Anshan, also an ex-Soviet destroyer. This is one of the members of the Project 7 class used in World War 2. All the surviving members of this ship class are in China now.
