@ keltos01: Did you get it working?
For me, the start menu is in English as well as the patrol orders. The radio messages, compartment names, and equipment descriptions are still in Russian, though I hear their translations are in the works. Also, the torpedos do appear to be American. I can't read the Russian descriptions, but they include the numbers 10 and 14 (Mk10 and Mk14 I assume).
Edit: Oh, you're talking about the sub names. No, my subs have Russian names. The first time I tried the BFB mod, I got a Porpise out of Pearl Harbor, but that's because I was picking the wrong year. The Baltic campaign is on the bottom of the "Year" list on the start menu.
@ sergei: No worries mate. Fantastic work you've done. I was just gonna muddle through by guess, but this is MUCH better. Thanks again, you deserve a beer or three
