...you could check Chineese U-47 Wolf Ocean Mod, it have many nice new ship and plane models, including turning fire control radarīs, moving crew on deck, new high quality textures, all work in progress !
iam not shure if he`s allowed to show his work outside chineese IP space, so this is an example what i found so far... (combined with new smoke and MEP)
...this screenshots are taken from a special mod compilation i work on (putting good things together with it, for example U-47`s Warship Mod & Living Silent Hunter), adding here and there something, at current private use only.
ps: there are 4 new CL`s, i included them as DD-type (7) vessels, so they are closing into a good torpedo fireing range (while you`re maybe enganging another BB) and are able to sink you in minutes if not carefull or without escorting cruisers (warship mod multiplay).
