I have thought this as well. The ships do appear somewhat larger if you get really close in free view but the ships still do not seem to be as BIG or maybe as long as they should. This may be a result of being represented on a 2d screen(monitor) or scaling in the game. Eye candy could be one possible reason, make the torps and sub easier to see with more detail. As I am not a programmer and a mediocre modeller(I'm an A/V guy) I cannot say for sure, but I have seen scale issues in most pc games to date, most specifically, space sims
