Space Battleship Yamato is a anime that do not needs introduction. Last year the series got a remake with new animation, characters, more story, more "real" science-fiction, etc.
Episode 13 has a good ship vs submarine, in a space sense and I thought in sharing. Here is Space Battleship Yamato 2199 ep 13, "The Wolf from Another Dimension"
