Callisto

This large moon’s tectonic stability and significant deposits of rare minerals made it an ideal location for Mars’ shipyards, the largest in the Outers. Most of the Martian Congressional Republic Navy’s fleet has been built orbiting Callisto, where the shipyards are capable of building hulls up to 700 meters in length: Donnager-class ships.
Port Hampton is the moon’s only settlement, dug into the walls of a large crater used as a launching point for ships carrying minerals up to the orbiting shipyards. Like many cities built around industries that require hard physical labor and long hours and weeks on shift, it has a frontier town reputation: a place for the jarheads and contractors to party and blow off steam on shore leave. Most of its permanent inhabitants are involved in businesses that profit from said shore leaves. A security force is maintained to handle any issues that stem from drunk marines and miners, supplemented by an MCRN battle group on station near the docks. MCRN’s most significant presence is in orbit, but their surface shipyards are under heavy technological and physical security as well - with regular drone patrols around the perimeter.
Callisto is one of the only moons of Jupiterwhere radioactive minerals are close enough to the surface for easy extraction, however it hasn’t created a strong economy. Mining and shipbuilding are the only sources of revenue, and revenue that comes only from Mars. The moon is one of the truest examples of a buyer’s market.

History

The Epstein Drive was born on Mars at the research center at Dhanbad Nova and its nearest shipyard outside Londres Nova —long ago dismantled, but commemorated with a plaque on the planet’s surface. The eighteen cargo ships that almost started the war between Earth and its fledgling colony became the first ships of the new Martian Congressional Republic Navy, fitted with Epstein drives.
Shipyards had been the point of contention between the United Nations and newly formed Martian Republic that nearly sparked a war, and given that Mars had shared their revolutionary technology for independence, they had little interest in maintaining their primary shipbuilding facility within ‘close’ reach of Earth. Callisto provided the ideal candidate for the MCRN’s new shipyards: the moon of Jupiter already had a small Martian research station in operation and an excess of minerals close to the surface for easy extraction. The light gravity would also allow for crews to work on the moon’s surface as well as in orbit.
