These are real space ships/ fighter ships from video games and movies that I've decided to replicate in this game. I've tried to be as true to the source material as I possibly could. Some things had to have obviously changed for functional use, as well as to be able to keep the ascetic of the original source material.
Samus Aran's Gun Ship:

The USS Enterprise:

The Millennium Falcon:

The Death Star:

We Need To Go Deeper (Submarine)

note Yes it feels understaffed, and not to functional, but that's what the game is about. ^
Weaponized Space Octopus

The Statue of Liberty

Metroid

Fetus (Cause, why not)

More to come, post your replica ships below, or post suggestions for me to make and post for the future.
List of suggestions:
-Star Wars - Home One (WIP) Yes, this one is still to come. These are all the designs above were made before this suggestion. I just don't have the time at the moment to upload all of them. I am almost done with the art project I'm working on, after that, full steam ahead on this suggestion.
