The Polaris is a corvette-class capital ship developed by Roberts Space Industries (RSI) for the United Empire of Earth (UEE) Navy. Intended for combat situations, the Polaris was designed with a command center, repair and refuel facilities, and a bay capable of transporting one or more small fighters. It is used by the Navy to conduct patrols and conduct search and rescue operations.

Development of this ship was accelerated as a part of the SEY 2946 Militia Mobilization Initiative, after which a limited number of Polaris were made available for purchase on the civilian market.
