Cryo Industrial

The Cryo Industrial-class is a self-contained ice economy in a hull. Harvest ice, process it into water, coolant, and fuel components, package the products, and haul 3,000 units of finished goods to market without ever docking at a station. The Federation controls the water supply chain because whoever controls ice controls fuel and life support. The Cryo Industrial is how the Federation exercises that control: industrial-scale cryo-processing that reduces entire ice fields to refined commodities. Zero weapons because the Cryo Industrial's value makes it worth escorting properly.
