In an alternate universe, following the September 11th attacks, "The F.L.E.E.T. Project", or the FLeet Expansion and Enhancement Test, was initiated by a team of American engineers, codenamed "Constitution", who were contracted by the U.S. Navy to research and develop enhancements for the United States Navy. Specifically, how to condense WWII-era ship technology into the size of a human being. Essentially, making ship girls.
All was not well however. While many ship girls were successfully built, activated for initial testing, and prepped for transport to the States, most of them never reached their assigned naval yards before the outbreak of World War III in 2010 that saw the United States and Iran throw nukes at each other. With their developers forced into shelters for their own safety, it seemed as though the ship girls were doomed to fade to myth.
The year is now 2029, and the world is...not actually an okay place to live. Enter our hero, Damon Polchow. Born shortly after the war, he has basically seen all of what life had to offer After the End. He's hot on the trail of a possible ship girl, following a lead provided by a scientist who had worked on the F.L.E.E.T project, and eventually ending up in the scientist's former home in the suburbs of what used to be Houston, Texas. It is here that he encounters his first ship girl, Fubuki-class destroyer Murakumo. But what begins as a lofty yet simple goal of making a better world, by force if need be, quickly takes some unwanted turns when new complications and enemies, some less foreseeable than others, start to come out of the woodwork.
