Naval Command, which was also referred to as Supreme Naval Command, High Command, or Imperial Star Fleet Command, served as the command framework for the Imperial Navy. This organization was restructured from the Naval Command of the Republic Navy and its possible connections to the Admiralty are noted.
The command structure was composed of four distinct divisions: the Line Branch, the Flight Branch, the Fleet Support Branch, and the Support Service Branch.
In instances where military operations were deemed sufficiently important, Naval Command had the capacity to participate directly. A significant illustration of this involvement is the events that transpired on Constancia, where the Command played an active role in suppressing the native population due to their telepathic abilities, and also gave orders for a group to immediately stop the Millennium Falcon.
