Real Fleet Boat (RFB) and Trigger Maru (TM) are the ones to check out. Both have their individual qualities and depends on what realism you wish to take on. Both are excellent super mods in their own right. Great effort by both teams in my books.
Run Silent Run Deep Campaign (RSRDC) is virtually a complete re-write of the campaign files and is excellent. It is based on research and lurker_hlb3 has done a terrific job simulating the events.
Then of course there are the Environmental and Pacific Environment mods that truly change the whole aspect of the 3d environment. Absolutely amazing work by these guys involved.
Anyway, check the link out as there are many more amazing mods for the grabbing by truly creative and skillfull persons.
