Earth"s formerly verdant valleys and sapphire seas have been turned into barren desolation by the relentless barrage of planetary bombs launched by the expansionist Gamilas Empire. By 2199, humanity has fled into subterranean metropolises to shelter from the lingering radiation.
Yet hope endures, for the remote world Iscandar offers a final rescue through its Cosmo Reverse System, which can heal Earth"s irradiated terrain. In a last‑ditch effort to secure this device from Iscandar, the Earth Defense Force commits all its remaining assets to the Yamato—a cutting‑edge warship powered by an inexhaustible Wave Motion Engine.
From fledgling officer Susumu Kodai to seasoned commander Juuzou Okita, the Yamato"s crew comprises individuals with diverse battlefield experience. Despite these differences, they share a single objective: to finish their perilous 168,000‑light‑year trek to Iscandar and rescue humanity from impending annihilation.
