Covenant fleet

The Covenant fleet was the vast space-borne naval component of the Covenant military. Their roles included 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, the Covenant fielded thousands of warships, most being able to carry fighters, dropships, ground troops and vehicles; after the Human-Covenant War, most of these fell under the control of the various Covenant remnants. Each Covenant fleet unit is essentially a fully-rounded armada, and 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.

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 those 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.

Organization
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.

Ship classification codes
The Covenant used a unique classification standard in its fleet. The United Nations Space Command assigns three-letter codes for each class of Covenant starship. These codes are transliterations of the "Primary", "Secondary", and "Tertiary" classification codes that were used by the Covenant fleet. Each starship is classified based on its role and abilities in a fleet. An example of this three-letter code would be the "ORS" in the ; each letter in the code represents a different role, ability, or design within the particular vessel. The letters are ordered by importance of the feature. The known letters used in the classification system are A, C, D, O, P, R, S, and V. Of these known letters, only the following representations are known:
 * The O denotes "Ordained", meaning the starship is outfitted with a Forerunner augmentation, and is not a mission type.
 * The R represents "Reverence", meaning the vessel can conduct reconnaissance missions and excavate Forerunner artifacts.
 * The S means "Salvation", which refers to any vessel armed with a energy projector.

It is unknown if the repetition of a letter in a class' classification—such as the —has any significance. It is also important to note that while Covenant fleet personnel occasionally referred to their vessel's class by one of its three-letter codes, there was not a specific class that the a code belonged to. For example, Incorruptible was occasionally referred to as a "Reverence-class cruiser", although it was actually an ORS-class heavy cruiser. The term "Reverence-class" truly refers to multiple vessels ranging from cruisers to small scout ships.

This classification system is similar to the hull classification symbols used by the UNSC Navy.
