Some lore:

The GPN Marie is the heavy cruiser of a private navy ownned by a billionaire, the ship is named after the man's mother. This ships's construction started along side with the Yun destroyer and an aircraft carrier named Joseph, but the Marie's construction finally finished up to 3 years after the Yun was launched. Midway through construction, the man decided to switch most large quadruple AA turrets for Rheinmetall Oerlikon autocannons. After 3 ships were completed, the man set out to build a country of his own on an artificial island built by him. After the country was created, so was a proper navy, the 3 ships joined the new navy and recieved a new camo that looks... surprisingly close to the old Kriegsmarine camo, which cause a lot of controversials. After serving in the new navy for a few years, the Marie got upgraded with laser AA turrets and a new microwave anti-air system. This ship went on to fight in many battles including an invasion from a neighbor country, with an impenetrable AA defense, no modern warships can defeat the Marie as soon as they came into its guns' range.
