Hopefully Jacques Druel will chime in on this as he designed the kit!.
I believe it is pre-war as the kit lacks the large forward workshops that were suspended under the forward section of her bow. However, since I'm not an expert on this vessel, this is just an educated guess. Once I actually build her, I'll do the requisite research to match a particular period.
