Interceptor Two comprised a squadron of starfighters, and they were part of the New Republic Defense Fleet's Fifth Battle Group, specifically assigned to the Intrepid, an Endurance-class fleet carrier.
Leading up to the Battle of Doornik 319, Interceptor Two stood ready for immediate deployment from the Intrepid. Furthermore, when the Intrepid jumped into the system, Interceptor Two helped form the fleet carrier's defensive fighter screen.
