Uh, well, heh heh, it’s a starship in the trek universe but not an enterprise, or even a fed ship. It’s a fanfic piece of mine about a person who, thru a series of strange disasters, ended up with a tremendous amount of technical and engineering skills left in his mind by 3 dead vulcans and who was subsequently exiled from his homeworld, and began designing the ship for the hell of it while on the enterprise D.
Later the leaders of his homeworld threatened his family if he didn’t help them do an intolerable act, so he loaded up a very powerful AI system with the designs for the ship, called “Hephaestus”, hacked enterprises mainframe computer for every bit of data on fed ship technology it had, gave it some replicators and used a shuttle to slingshot it back in time over a century into a resource rich area. The AI started gathering resources, used a Von Neuman process to create more and more autonomous units to mine the area, converted a hollowed out asteroid into a construction bay, built the hephaestus over a decade and then brought the ship back to him via another time warp.
So it is based on and influenced by fed tech and design, but not a fed ship per se’.
