Hello all,
I've finally scanned and uploaded all of my vehicle concepts as promised.
The "Hoover", a steam powered hovercraft, hovers in low gravity environments on steam jets. It has two wing engines, both steam powered, which propels the craft and steered. Until recently it was designed to safely move around exploring asteroids, and wasn't very fast.
Then a war broke out.
The most recent model added a rear rudder and extra propeller to help the craft move faster and more accurately, and also a heavy shell, rendering the Hoover useless in normal gravity environment, but making it perfect for helping defend asteroid colonies from competing empires and factions. Two small frontal cannons were added, allowing the Hoover to chase down and shoot opponents, or fight face to face with opponents, the frontal armour protecting the vehicle while the cannons took care of the enemy.
[This craft is more than likely American, with it's reference to the Civil War in it's shell.]
Next, we have the "Ironclad" ship. Not much in the way of ideas, though again, it is probably American.
Here's a design for an Asteroid Rover. It could be from any empire.
Also a rough idea for a Space "motorbike" a small starfighter, that also has propellers to enter atmosphere, and rockets for in space.
Then we have a random chopper style vehicle, probably also suited to low-grav environments. Who knows. It could also feature on Venus.
