Editing Covenant ship classification system

{{Status|Canon}}
{{Callsign}}
The '''Covenant ship classification system''' is an organizational method that is used by the [[Covenant]] to categorize their [[warship]]s. The Covenant's spacecraft classifications do not follow the standards typically used by [[human]]ity.{{Ref/Site|Id=Catalog|URL=https://www.halowaypoint.com/en-us/forums/db05ce78845f4120b062c50816008e5d/topics/catalog-interaction/4c3e1c6f-6519-4ee0-83a4-4bac13bf07a3/posts?page=27#post263|Site=Halo Waypoint Forums|Page=Catalog Interaction|Quote=[Covenant] naval classifications do not follow Human standards.|Quotee=Catalog|LocalArchive=Catalog/Archive/2014#Post #7|D=30|M=07|Y=2021}}

==Major categories==
Analogous to the [[UNSC Navy]]'s formalised starship classifications, the Covenant fleet is divided into several major groupings, each which fulfil a particular niche required by their navy. These terms may be occasionally referred to as a "class" name - for example, a ''Varric''-pattern heavy cruiser may sometimes be referred to as an examiner-class cruiser to distinguish it from the empire's other heavy cruiser classes.{{Ref/Book|Enc22|Page=265}}

===Advocates===
Advocates served as the core of most Covenant fleets, and consist of frontline warships with crews eager for honour and victory. They carried out the orders of their superiors without question or delay.{{Ref/Reuse|Enc22}}

While no presently-confirmed vessels yet fall into the advocate role, the {{Pattern|Ket|battlecruiser|}} and {{Pattern|Elefen|battlecruiser}}s and their predecessor, the {{Pattern|Maugen|armored cruiser}}, match the given description almost perfectly.

===Attack ships===
Attack ships were the most common warships available to the Covenant, but were considered beneath the notice of most Fleetmasters except for use as diversions to distract enemies from more valuable targets, generally being pawned off to Kig-Yar or Jiralhanae and other profit-focused crews.{{Ref/Reuse|Enc22}} They were usually assigned to patrol Covenant space, inspecting and escorting shipping that carried the tithes of Covenant worlds or pilgrims to High Charity.{{Ref/Reuse|warfleet72}} Sangheili crews that found themselves assigned to such vessels tended to regard them as inglorious assignments, eager to prove themselves worthy of transfer to more prestigious assignments in battle, such as examiner type ships,{{Ref/Reuse|warfleet64}} but were unenthusiastic about protecting executioner ships when assigned as escorts.{{Ref/Book|Id=warfleet72|HWF|Page=72-73}}
*{{Pattern|Zanar|light cruiser}}{{Ref/Reuse|warfleet72}}
*{{Pattern|Mutan Et|storm cutter}}{{Ref/Book|Id=Enc22p269|Enc22|Page=269}}
*{{Pattern|R'sikosh|man o' war}}

===Coadjutators===
Coadjutators served as special-purpose vessels originally built for the Covenant ecclesiarchy, and as such their initial role was obscured in record. Many of them wound up serving exclusively as escorts and occupational security roles.{{Ref/Reuse|Enc22}}

===Conservators===
Conservators are conventional warships in the Covenant, elevated with a greater purpose and degree of prestige. They were usually found operating as squires for pilgrim ships, missionaries and emissaries from High Charity.{{Ref/Reuse|Enc22}}
*{{Pattern|Akton|escort}}{{Ref/Reuse|Enc22p269}}

===Examiners===
Examiners were valuable and rare ships usually crewed by experienced crews, with personnel considered judicious and bold. They frequently employed Forerunner technology in their construction, and Ministries that wished to crew and deploy one needed direct approval from a Hierarch. However, they were easily reassigned.{{Ref/Book|Id=warfleet64|HWF|Page=64-65}} Examiners were generally commissioned during times of great need, and allocated to only those who had proven themselves.{{Ref/Reuse|Enc22}}
*{{Pattern|Kerel|assault carrier}}{{Ref/Book|Id=Enc22CAS|Enc22|Page=262}}
*{{Pattern|Syfon|assault carrier}}{{Ref/Reuse|Enc22CAS}}
*{{Pattern|Varric|heavy cruiser}}

===Exarchs===
Exarchs were the largest and most powerful warships within their respective domains, and even the Covenant as a whole. Their crews saw the opportunity to serve on these vessels as an unimpeachable honour.{{Ref/Reuse|Enc22}}

The size and role of the {{Pattern|Sh'wada|supercarrier}} may suggest it to be of exarch status.

===Executioners===
Executioners were unusual in Covenant ship standards, as they represented some of the only warships built with no other goal in mind except for warfare. Due to this, they were typically regarded as a distasteful reminder by the Prophets that the Great Journey depended on the use of violence, and were assigned far from [[High Charity]] during times of peace, across the Covenant's expansive border. This made them difficult to bring to bear when the Covenant mobilized for war with humanity, delaying their assignment to the frontlines by years.{{Ref/Book|Id=warfleet60|HWF|Page=60-61}}{{Ref/Book|Id=Enc22p266|Enc22|Page=266-267}} Their sheer destructive potential meant their construction was rationed.{{Ref/Reuse|Enc22}}

*{{Pattern|Kewu|battleship}}{{Ref/Reuse|Enc22p266}}
*{{Pattern|Rasus|interdictor}}{{Ref/Reuse|Enc22p266}}
*{{Pattern|Rothen|fireship}}{{Ref/Reuse|Enc22p266}}
*{{Pattern|Sinaris|heavy destroyer}}{{Ref/Reuse|warfleet60}}
*{{Pattern|Wik|light destroyer}}{{Ref/Reuse|Enc22p266}}

===Procurators===
Procurators were far more common, but were independent of military chains of command or system governors, though usually complied to requests, and needed Hierarch approval to attach to fleets in order to curb the power of the Sangheili. They were also commanded by San'Shyuum Shipmasters, rather than Sangheili, further forcing Sangheili fleets and colonies to depend on the Prophets for their supply lines. When High Charity [[Fall of High Charity|fell]] to the Flood and the Prophet of Truth was killed, many of these ships departed Covenant space with their Prophet commanders and loyal escorts, joining the [[San'Shyuum flotilla|rest of the San'Shyuum]] fleeing Sangheili retribution, making them a rare sight in the post-war era.{{Ref/Book|Id=warfleet68|HWF|Page=68-69}} Procurators often housed [[Assembly Forges]], food reserves and the [[Huragok]] personnel needed to maintain Forerunner equipment.{{Ref/Reuse|Enc22}}

Procurator ships include the following;
*{{Pattern|Mjern|agricultural support ship}}

===Vestiges===
Vestiges were old warships that served during the [[War of Beginnings]], when the Sangheili were united against the overwhelming power of the San'Shyuum's Keyship. Fleets of Vestiges were sent off to drift in space or buried in caverns beneath airless worlds, with any records of their history or battle-honors deleted from all data archives by clans that wished to overturn the [[Writ of Union]]. Forgotten by all but a few dedicated lineages, these vessels were reclaimed by Sangheili Covenant remnants after the [[Great Schism]] to be pitted against other Sangheili forces and burn what they were built to protect.{{Ref/Book|Id=warfleet78|HWF|Page=78-79}}

Vestige ship classes are generally named after sailing ships from the Age of Sail.

Vestige warships include the following;
*{{Pattern|Hekar Taa|blockade runner}}
*{{Pattern|Lursu|brigantine}}
*{{Pattern|R'sikosh|man o' war}}
*{{Pattern|Rwaru|carrack}}
*[[Barque]]

The {{Pattern|Useumru|voidpiercer}}, constructed in the first two years of the Covenant's existence, may also count as a Vestige warship.

==Three-letter classification codes==
During the war, the [[United Nations Space Command]] and [[Office of Naval Intelligence]] attempted to classify Covenant ships based on observation and limited intelligence about the Covenant's own ship codes. This allowed UNSC analysts to create a schema for identifying Covenant vessel types roughly synonymous with [[human]] naval [[Hull classification symbol|hull codes]]{{Ref/Reuse|Enc22}} - though these classifications do not map perfectly to human standards.{{Ref/Reuse|Catalog}} These codes take the form of three letters forming the Covenant ship's "class" name (ie CCS-class), with each of the three letter codes derived from the Covenant's internal mission codes.{{Ref/Book|Id=Enc22|Enc22|Page=260}} Following the end of the war with the Covenant, cooperation with the [[Swords of Sanghelios]] revealed the true complex extent of Covenant naval organisation to human analysts, and a shift away from the three-letter codes.{{Ref/Reuse|Enc22}}

The three-letter codes are transliterations of a given ship's primary, secondary and tertiary classification codes used in the Covenant fleet, with the letters' ordering determining the importance of that feature, role or ability in the ship's mission.{{Ref/Site|Id=Have S'moa|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-have-s-moa|Site=Halo Waypoint|Page=Canon Fodder - Have S'moa|D=30|M=10|Y=2021}} For example, the [[ORS-class heavy cruiser]] would be broken down as follows;
*'''O - Ordained:''' This is not a mission type but instead denotes that the ship is enhanced with [[Forerunner]] technology such as a [[relic core]].{{Ref/Reuse|Have S'moa}}
*'''R - Reverence:''' Reverence mission codes mean that a ship is capable of conducting reconnaissance missions and excavating Forerunner artefacts.{{Ref/Reuse|Have S'moa}}
*'''S - Salvation:''' Salvation mission codes refer to a dedicated warship capable of cleansing their enemies with "holy fire".{{Ref/Reuse|Have S'moa}}
As such, the ORS' primary characteristic is that it is a Forerunner-enhanced ship, primarily intended for reconnaissance and excavation missions - with pure combat only a tertiary focus.{{Ref/Reuse|Have S'moa}} Accordingly, Covenant ships (such as in the case of ''[[Incorruptible]]'') may sometimes be referred to off-hand as "''Reverence''"-class ships, though in reality any ship bearing the R in its letter code (such as the ORS and CRS-class cruisers, CAR-class frigate, etc) could be described as a ''Reverence''-class.{{Ref/Reuse|Have S'moa}}

The known letters used in the classification system include '''A''', '''C''', '''D''', '''O''', '''P''', '''R''', '''S''', and '''V'''. Of these known letters, only the O, R, and S designations are known (listed above), though it should be noted that the letter classification codes do not have any correspondence with the class designations used by the Covenant (detailed at the top of this article). Equally, it is unknown what significance repetition of the letters in a class name (such as the CCS and SCC-classes) signifies. Due to the limited understanding of Covenant ship organisation and manufacture, some human-ascribed three-letter codes correspond to multiple individually-recognised [[design pattern]] variations, similarly to the errors present in their [[type classification system]] for ground equipment. For example, both the {{Pattern|Kerel|assault carrier|}} and {{Pattern|Syfon|assault carrier|}}s of assault carrier maintain the CAS hull code.

The [[vestige]] warships of the [[Sangheili]] are not given three-letter codes, owing to their age - predating the [[Writ of Union]].{{Ref/Site|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-holiday-shipping|Site=Halo Waypoint|Page=Canon Fodder - Holiday Shipping|D=01|M=03|Y=2021}}
