Townships are commonly founded by one of the multitude of corporations, they buy the Primary Phase Habs in bulk and transport them and their new residents out in one massive convoy (normally protected by a Peacekeeper contingent) that travels to the intended site of the new township.  These convoys are targets for outland raider attacks as although they are heavily defended the resources sent with them are worth their weight in gemsite.
