Covenant fleet

A fleet is a basic organizational component of the Covenant military as well as the forces of its various remnant factions. Each fleet is essentially a fully-rounded armada, likely with dedicated logistical support. Their roles include ship-to-ship combat, orbital bombardment, the deployment of fighters and bombers and the method of delivery for the Covenant's occupational ground forces. At its height, it fielded thousands of warships, most being able to carry fighters, dropships, ground troops and vehicles. Each fleet is given a unique name with religious connotations similar to how Covenant vessels and colony worlds are named by their beliefs.

Although the Covenant's collective naval forces are referenced in some contexts as the Covenant Navy, it is apparent from the organization of their military that the Covenant does not maintain distinct service branches in the same manner as the UNSC and traditional human militaries.

Overview
The title of the fleet commander varies depending on the size and extension of the fleet itself. While smaller fleets or temporary task forces are led by Fleet Masters, larger fleets are commanded by Supreme Commanders. There are also cases where an individual with the title of Shipmaster has had command of a fleet. A fleet's highest-ranking individuals convene in a group known as Council of Masters. In some cases, a Minor Prophet is attached to a fleet as a representative of the High Council.

Many known fleets seem to consist of around one hundred starships of all types and variations, and are led by a prominent flagship, which is often an assault carrier or in rare cases a supercarrier. Capital ships, such as the iconic CCS-class battlecruisers, as well as numerous frigates and destroyers, usually serve as escorts to the flagship. Fleets are sustained by numerous logistics vessels, such as agricultural support ships, which are organizationally attached to warship fleets, providing food and supplies.

A number of combat legions are often attached to a given Covenant fleet, stationed aboard the various warships available.

Combined fleets
A combined fleet, as its name implies, is comprised of multiple smaller fleets and is led by a Supreme Commander, or, if of sufficient size, an Imperial Admiral. These fleets have larger duties, such as safeguarding and policing entire regions of Covenant-controlled space on their own. These fleets can have several hundred ships. High Charity was guarded by a combined fleet at all times. Some combined fleets are formed on a strictly temporary, task-oriented basis, such as a major invasion of a key enemy system.

Great Schism
Throughout the majority of the Covenant civil conflict known as the Great Schism, the Covenant military was violently splintered between those who continued to believe in the Prophets' wisdom and the Covenant separatists, who followed Arbiter Thel 'Vadam and opposed the Prophets' rule. As the battle raged, the High Prophet of Truth formally transferred command of the navy to the Jiralhanae, a position once exclusively held by the Sangheili. The Covenant separatists wiped out the primary loyalist fleet at the Battle of Installation 00.

Soon after the outbreak of the Schism, the separatists' numbers were reduced by a pair of disasters. At Joyous Exultation, the massive Combined Fleet of Righteous Purpose, headed by Imperial Admiral Xytan 'Jar Wattinree aboard the supercarrier Sublime Transcendence, was consumed by a NOVA bomb. At Onyx, a battle group headed by the cruiser Incorruptible was destroyed by the Forerunner Sentinels that comprised the artificial planet.

Due to this disarray, the only Sangheili fleet to fight in the last battles of the war was the Fleet of Retribution, which was led by the assault carrier Shadow of Intent. During the battles of Voi and the Ark the Jiralhanae-led loyalist fleet was mostly limited to Truth's fleet, which outnumbered the Sangheili three to one by the time of the Battle of Installation 00. This fleet contained a number of battlecruisers and assault carriers, led by Truth's Forerunner Dreadnought.
