cool. I was planning on having three kinds of armor for vehicles/ships. 
Nanotube is made by layering carbon nanotubes, like Kevlar. It is great against physical weapons, ok against energy. It is mostly made on Mars and Earth.
Ablative armor is made out of a titanium-aluminum alloy. It is good against energy, ok against physical. It is mostly made on the moon (the moon has large amounts of both titanium and aluminum).
Hybrid is layers of nanotubes held together by the titanium-aluminum alloy. It is good against everything, but isn't as good as nanotube armor against physical, and isn't as good as Ablative against energy.

Also, what purpose will your ship serve? Farming can just be added to one of the other ships (probably mining), as hydroponics tanks, nutrients, and cafeteria supplies don't weigh that much. We need mining and manufacturing, though.
