Download, extract to a temp folder. Go into Windows Explorer, copy the \Ubisoft\Silent Hunter Wolves of the Pacific\Data\Library\Torpedoes_US.zon to a backup. Switch to the temp folder, copy the Torpedoes_US.zon from either V1, V2, or V3 into the \Ubisoft\Silent Hunter Wolves of the Pacific\Data\Library folder, yes to overwrites. If it don't work, copy the backup file back in to restore it.
