Reupload of my mod since it was deleted because it techncally didn't provide any actual useable file or mod. Which is fair enough.
This time (tho not a fan of it) i will provide my save file as the actual mod file.

This is a video tutorial to recreate this ship.

3 mods are absolutely necessary to build this ship. 

    - kur00e's Unrestricted mod: https://www.nexusmods.com/starfield/mods/803

Use any mod that makes all the parts available in one spot, no matter what place.

I used:- Themudsy Atlantis Shipyard mod: https://www.nexusmods.com/starfield/mods/3918

and   - all the "no limit" mods by Synthlight


Important information about certain ship parts:

1.Some manufacturer parts are absolutely necessary to make certain combination possible! I wouldn't change all the Deimos parts, because some corners only work with Deimos parts, thanks to their angled edges. So change manufacturers at your own risk if you absolutely need to change them.

2.The ship has 4 "hidden" engines to give it decent mobility without ruining the design by slapping some more engines onto the ship just for the sake of it. Make sure you keep close attention in the video on how their mounted, it's very important that they dont stick out of the bottom of the hull.

3.You may noticed i left a gap in the bottom of the hull far forward in the centerline of the ship. You can close this gap if you want to, i created this gap there   to be able to cross under the ship without having to circle around it every time.

4.Some inner parts are made out of these light weight frame constructions. The ship is basically at it's mass limit and any further, heavy, addition will reduce the grav drive from 30 to 29 or lower.

5.I noticed a small mistake while recording the video, the rear turret didn't have the 2 guns attached to the reactors. I fixed that in the video so feel free to do so aswell.

Last but not least, dont forget that this is a mod that goes way beyond any ship size Bethesda had originally in mind for the player to create.
Whilst i didn't have any game breaking or soft-locking issues with it so far, be aware that there will be clipping into certain objects and i can not guarantee that using this ship in every mission will not break your game. Use it at your own risk and make sure to create backup saves whenever you're uncertain.
