Built this craft with help of your mod. Kinda overkill but I just wanted to see how big I could get before loosing all my comfy FPS amounts on my system (here it is stil around 30-40 FPS average even tho all the visual mods).
It can pretty much go anywhere in the system. It has extreme amounts of habitation time and supplies for the life-support as well so they are not like gonna run out of food or oxygen.
I even know how to easily make this in space. Well without planetary launch pads it would be hard because of the fuel tanks. I guess I could try send them empty and dock them. But even that would be hard.
Resupplying it will be a pain. Which is why I have a few smaller designs more suited for playing. It was fun to test and use this huge monster tho.
This is the exact amount of engines this thing needed for around 1+ m/s acceleration. Less and the amount of time Delta-V burns take kills me.
Here is the life-support. Nicely located in the habitation section.
To run each engine I got a nuclear reactor for each. 12 reactors, gives quite the heating. Needed a few of the largest radiators.
And for fun I made it go all the way to Eve but I de-orbited it at some time to see the atmospheric effects tear it apart. I don't know why but I love seeing stuff burn in the reentry in this game.
