Synopsis: This anime takes place in a world where due to the icecaps melting the oceans levels have raised and many of the old coasts are now under water.  During this time a fleet of ships called the Fog appeared and started an all out war against the human fleets.  These ships all looked like world war I – II ships for some reason.  With their superior technology the fog fleets drove the humans from all the oceans on the planet and caused each area to become isolated.  7 years have passed and the Japanese navy is searching for ways to fight against the fog on equal ground.  The only ship that has been able to sink any fog ships is an ex-fog sub called U-401.  The anime follows U-401 and her crew as they search for a future where all the world is united.
