The system defense brick inspired the Caltrop. This one is in the same price bracket (right on it, in fact (Brick: MCr15.236. MCr13.7124, Caltrop: MCr15.622. MCr14.06) and five times the size.
It is using what the spreadsheet decided. There isn't an option to turn off the basic power, so I suppose it is on. I tried to turn off the artificial gravity and halve the basic power cost, but the sheet got all huffy. Not sure why. Seems like a planetoid should be able to have no artificial gravity.
I've updated it to have a computer/5 and included the robotic interfaces I forgot.
