When the Great War of 2077 occurred, most of the world was destroyed within hours. However, some fleets remain intact and brawled out against each other. One such fleet contains the Nuclear-Powered Super Battleship of the Democratic Federal Republic of Germany, FGS Karliana Mauser. The ship and its escort of four Nuclear-powered Missile Destroyers fight a naval battle against both the British Royal Navy and the French La Royale Navy in a three-way fight of the Battle of the Wilhelmshaven.

The Battle was costly with FGS Karliana Mauser and its escorts sunk, but not without sinking 80% of Royal Navy ships, while the French suffered a total annihilation of their ships in the three-way battle by a betrayal from United Kingdom. But before the Super Battleship sinks, authorization has been ordered by the admiral on board the ship to fire the experimental WMD shell, the Neutron Shell, onto the remaining enemy fleet. A mutually assured destruction to the end.

However, FGS Karliana Mauser would be transported to the World of Azur Lane without its crew or any of its escorts through an unknown anomaly. How will Azur Lane's command react to a possible traumatic Kansen that has not just enough firepower to hold on its own against an entire fleet but also weapons of mass destruction to wipe out an entire nation at will?

Story had been remade to a new story "Fallout Nuclear Battleship", check that one out instead.
I will keep the original here for anyone to read.
