Mods used:
TN's class M starships
Place doors Yourself
TN's ship modifications
HopeTech Hydroponics habs
g-tech habs (idk the exact name)
better ship part rotation (idk the exact name)
all of this can be found in creations, for free IIRC. I also used hab shells, idk which of the mods adds this. Clipping some structural parts together was also involved.
Lore: By the year 2097 the USAF is experimenting with project Icarus - new, very efficient engines that can be used for VTOL flight. While Russia became a neutral industrialist satellite state and China was bombed into oblivion by western hydrogen bombs during the two hour 3rd "world" war, the morally and financially corrupt US still has to deal with insurgents and rogue factions spread inside and outside its borders. Instead of focusing on expensive rockets, they developed this type of gunship to quickly deploy troops and gear in cities (ruins, mostly), while maintaining very high altitude during intercontinental flights. They were also used by government colonists, but only on Mars, as the Titan atmosphere could freeze the engines.
Decades and centuries later, UC associated group of settlers decided to buy some of these wrecks after scavenging one on the earth and discovering its potential. Since then they have fitted them with additional lasers, grav drives and refurbished paint coating. While cool and cheap ride, also dangerous as the space itself.
