When the Megaroad Colony Ships where first being constructed many in the United Nations Government would believe that these colony fleets would need dedicated factory and support ships thanks to the thought that these colony fleets would be traveling for decades they need a way to replace combat losses as well as producing equipment for the colony itself. While some early Megaraod Fleets would use modified captured Quiltra Queleual Class ships for support ships. Later fleets would need a better capable ship to do this. Therefore the Vulcan Class Long-Range Factory Ships would be introduced to serve this role in a colony fleet starting with the Megaroad-04.
