Space Battleship Yamato 3

This time around, earth is in the same predicament as Gamilus was in the first series, and most of the series, Yamato (with several other unnamed ships which are implied to be upon the same task) seeks for another planet for humanity to migrate to. Somewhere deep in space, Desslok is engaging in a war against another superpower, the Bolar Federation, and soon Musumu Kodai and his friends are in the middle of this armed conflict. (imdb)
