Can members here when posting, be a bit more explicit with there posts..........many posts made here are a big meaningless.
Thanks!
According to PLAN's rule, if the ship do not change much, then they will use the same model number, and if not, use a new model number. There are many proposals for type 054B on the net, however, if some of them become true, it should be called type 057 because it is so different from type 054A.
I don't know the exact design, but from public information, I think the basis of the design from type 054A to type 057 should be using QC-185 instead of diesel engine.
