Northerner
Alright, I'm ready. Working during lots of short breaks between the studying. I can reveal my first mining corporation. (I was not sure if you want to separate mining companies, so I made one. Also, I did not check price tiers, because I didn't know if they were relevant.)
I even made a flag!

IDA : The Interstellar Drilling Association

Border Patrol
These ships ensure that no intruder enters IDA mining territory. Investment must be protected.

Dril Pod
The cheapest mining vessel produced by IDA. Meant to drill their way through large asteroids.

Extractor
The backbone of IDA. As cheaply built as possible, yet sturdy and versatile, the Extractor is both capable of mining and defending against pirates if necessary.

Mining Platform
Not even the biggest asteroids can last long against a Mining Platform. However, it is prone to attacks from longer range.

Scatterer
The Scatterer stays true to his name and scatters asteroids and pirates alike.

The Forge
The juwel of IDA. It's abillity to serve as an outpost and and battlestation has made some name. Usually this monstrosity is used to create Scatterers, for not every workshop has the room for that.
(Note: These are not really designed for combat nor am I a master of design. If you don't like them feel free to say what the problem is so I can improve.)
