Historically correct US ships and planes.

[Major Johnson]

I know I brought this up a few years ago. I took quite a break from sub siming, but I recently got the itch to sink some Jap tonnage. I remember starting a career in Pearl and how the carriers were of an older class and the planes on them weren't correct as well. Someone said something about the game makers couldn't get the rights to use the proper ships and planes. Has that issue been resolved and maybe corrected in a mod?? Just wondering.
Thanks!
