Model of rumoured 054B (for export?) on exhibit at Langkawi, Malaysia.....
PS of 054B, resemble a small scale 055
Another version, possibly with all electric propulsion......
Those CGIs have been around for a while, but they're not really connected with the model
More intruigingly, is because there actually were CGIs back from 2014 by the same artist who drew a model of a frigate he labelled as "057"... which was posted on a few forums but wasn't taken too seriously, until late last year/early this year when the first model of that ship showed up as an export frigate design.
And the CGI from 2014 is almost identical to how the model turned out to be, only big difference being the CGI had a H/PJ-38 130mm gun whereas the model seems to have the 76mm gun, and the VLS platform is also a bit different although the first model shown at IDEAS last year seemed to still have the high VLS platform as in the CGI.
What is interesting is whether the artist had some insight into what CSSC was cooking up at the time, which would be quite an interesting development, or perhaps more strangely is if CSSC saw the artist's CGI and decided it was a good shape to build a frigate around it. I would have to go with the former rather than the latter but I mean who knows.
However, I strongly believe that neither the CGI, the model or the CGI that davidau posted are reflective of what the real 054B or "057" will look like. The model is an export frigate design, but it doesn't correspond to what the 054B will likely be, and more importantly it would be quite a departure for China to show the design of a new big ticket item like a new frigate, at an export or defence expo first, prior to its construction and launch in China itself.
