Imperial Navy Terminology
Chain of Command

In addition to the rank structure of its personnel, the Imperial Navy has an organisational 'rank' structure. At the top of the Chain of Command is the Admiralty. Below this comes High Command, then Fleet Command, then First Command, and finally the senior bridge officers of a capital class ship.

Admiralty: The Imperial central government is organised into a series of Ministries. The Ministry for the Imperial Navy is called the Admiralty. Rather than being run by a Minister the Admiralty is run by the Grand Admiral.

High Command: The leadership of all fleets within a theater of operations. In peacetime this is usually a sector, in times of war a theater may shift and grow with the progress of the war.

Fleet Command: The leadership of a fleet ... an Admiral and his staff officers.

First Command: The leadership of a squadron ... a Commodore and his staff officers. When the squadron is part of a fleet, First Command can become marginalised in importance as Fleet Command takes charge. But when a squadron is detached from a fleet, then First Command may be the most senior present.


Stars: The Admiral ranks (O7-O10), so-called because of their rank insignia.

Bars: Officers rank O1-O6, so-called because of their rank insignia. O1-O3 have gold bars and are called "Gold Officers". O4-O6 have iridium bars (supposedly representing the power of the Iridium Throne) and are called "Iridium Officers".
