- For information on the floating continent in Space Battleship Yamato 2199, see Floating Continent (2199).
Gamilas forces invading the solar system discovered the floating continent sometime before 2199, and constructed a base on its upper surface. Several days into its first mission, the crew of Yamato, after getting caught in the intensive gravity of the gas giant, found the floating continent and landed on It for repairs. After fending off a Gamilas attack and lifting off, Admiral Juzo Okita ordered Yamato to turn around and test fire its wave motion gun at the base. The power of the weapon was underestimated, and instead of destroying only the base, the entire continent was wiped out ("Escape the Floating Continent! Crisis Calls the Wave-Motion Gun!").
