I noticed that many people have been having problems because the models of ships are not acurately represented. I worked on the Historical Improvements Project and myself and several others did meticulous research in ensuring the proper OOB, Ship Classes, Ship Construction Order for all the major powers. I would encourage anyone to download the HIP .83 if for nothing else you could incorporate our Naval OOB into the Total Realism Project. All capitol ships and escort carriers are included and classed. Just a side note, we kept destroyers and submarines as units, not individuals.
