Starships are, as the name suggests, spaceships capable of traversing to other stars. The basic rule is simple: If it uses a Hyperdrive, it's a Starship. If it solely runs within a single star system instead, it's a Spaceship. An important aspect is that most Starships are designed to never even get close to a planet, depending on space stations and spaceship transports to interact with planets. Due to their large size, most Starship classes are only built at a few different shipyards. The most famous one are the Luna Shipyards, located at Sol System. These are the only shipyards that can mass-produce Titans, the largest ships capable of entering Hyperspace. Luna does not produce military vessels, so companies use their own shipyards to retrofit Titans into Leviathan warships.
