Yamato is a space battleship serving in the Earth Defense Force. As the first Earth ship to utilize wave motion energy, Yamato would go on to save the planet and the human race from multiple interstellar and intergalactic threats. Yamato was destroyed in 2203 in an attempt to prevent the water planet Aquarius from flooding Earth's surface, but after lying dormant in the icy remains of Aquarius, Yamato was repaired and upgraded for future missions.
