The '''''Syfon''-pattern assault carrier''' {{3Letter|CAS|assault carrier}} is a [[design pattern]] variation of [[assault carrier]] employed by the [[Covenant military|naval forces]] of the [[Covenant]].{{Ref/Reuse|Enc22}} The ''Syfon'' served the Covenant (and continues to serve its [[Covenant remnants|remnants]]) as a commonly-employed configuration of the design, complementing the much rarer {{Pattern|Kerel|assault carrier}}s which could only be constructed with explicit [[Hierarch]] approval.{{Ref/Book|Id=WF|HWF|Page=70-71|Quote=The smooth hull and distinctive rear cowling marks the ''Shadow of Intent'' as a Kerel-pattern assault carrier, a rare Hierarch-approved variant of the more common Syfon configuration}}

==Overview==
===Design details===
''Syfon''-pattern vessels can be most easily distinguished from their ''Kerel''-pattern counterparts by their more segmented hull plating. Of particular note, the ''Syfon''-pattern features numerous skyscraper-like protrusions extending from the dorsal surfaces of the ship, where the ''Kerel'' has an extremely consistently smooth hull covering. The ''Syfon'' is a commonly-seen variation of the assault carrier design.{{Ref/Reuse|WF}}

''Syfon''-pattern assault carriers can also carry large nature preserves on board, similar to those housed on {{Pattern|Mjern|agricultural support ship}}s. One such example was used by the [[Prophet of Regret]] aboard ''[[Solemn Penance]]'' as a place to carry out his official duties.{{Ref/Game|Id=h2a|H2A|Terminal (Halo 2: Anniversary)|Terminal 14}}

===Power and propulsion===
''Syfon''-pattern carriers are powered by a large [[deuterium]]-[[tritium]] [[pinch fusion reactor]] housed in the central mass of the ship, inside a large and cavernous space.{{Ref/Reuse|H2Cairo}}

===Armaments===
The ''Syfon'' boasts an identical armament loadout to its ''Kerel'' counterpart. Its primary weapon is an [[Excavation beam|''Infernus''-pattern excavation beam]], with an additional two [[Plasma lance|''Urpeon''-pattern plasma lances]] for heavy anti-ship work. The class is additionally fitted with eight [[Plasma beam emitter|''Luxor''-pattern heavy plasma beam emitters]] and twenty-four [[Plasma torpedo|''Mictix''-pattern heavy plasma torpedo]] silos, alongside an array of 700 [[Pulse laser turret|''Ferriel''-pattern pulse laser]] turrets.{{Ref/Reuse|Enc22}}

==Ships of the line==
*''[[Day of Jubilation]]'' - Served in the [[Fleet of Sacred Consecration]] during the [[Battle for Earth]], and was destroyed in the opening hours by [[John-117]].{{Ref/Reuse|H2Cairo}}
*''[[Enduring Conviction]]'' - Served in the [[Fleet of Recalcitrant Ire]], before going on to join the [[Banished]]. Destroyed over [[Installation 00]] during the [[Second Ark Conflict]].
*''[[Solemn Penance]]'' - Served in the Fleet of Sacred Consecration as the personal flagship of the [[Prophet of Regret]].

==Operational history==
''Syfon''-pattern carriers came into service during the [[Third Age of Discovery]].{{Ref/Reuse|Enc22}} They served the Covenant as a more common pattern of assault carrier until the empire's end in [[2552]]. The twin ''Syfon''s ''[[Day of Jubilation]]'' and ''[[Solemn Penance]]'' - the latter personally commanded by the [[Prophet of Regret]] - led the [[Fleet of Sacred Consecration]] in a campaign to [[Glassing|glass]] dozens of [[human]] [[Human colonies|colony worlds]] during the [[Human-Covenant War]], and were ultimately the ones responsible for beginning the Covenant [[Battle for Earth|attack]] on [[Earth]] in October 2552.{{Ref/Reuse|Spartan}} ''Day of Jubilation'' was destroyed in the opening actions of the campaign, and ''Solemn Penance'' was forced to flee the engagement, ultimately escaping to [[Installation 05]] and beginning the [[Battle of Installation 05]].{{Ref/Level|H2|Metropolis}}{{Ref/Level|H2|Delta Halo}}

Following the Covenant's collapse, at least one ''Syfon''-pattern, ''[[Enduring Conviction]]'', fell into the hands of the [[Banished]]. ''Conviction'' was persuaded to abandon the [[Fleet of Recalcitrant Ire]] and ultimately served [[Atriox]] as the flagship for the force brought to [[Installation 00]] in late [[2558]]. Months later, the ship would be destroyed thanks to actions by the {{UNSCShip|Spirit of Fire}}.{{Ref/Level|HW2|The Foundry}}{{Ref/Book|Enc22|Page=461}}

==Non-canon and dubious canon appearances==
===Silver Timeline===
A ''Syfon''-pattern assault carrier served as the [[flagship]] of the [[First Fleet of Solemn Accord]].{{Ref/Film|Id=Thermopylae|TV|Episode=[[Thermopylae (TV Series)|Thermopylae]]}} During the [[Battle of Installation 04/Silver|Battle of Installation 04]], it engaged the UNSC fleet until [[Kai-125/Silver|Kai-125]] rammed a captured {{Pattern|Ceudar|heavy corvette}} into the assault carrier, destroying both ships, seemingly at the cost of her own life. The assault carrier's destruction allowed the UNSC to gain the upper hand and decimate the Covenant fleet.{{Ref/Film|Id=Halo|TV|Episode=[[Halo (TV Series)|Halo]]}}

;Special Rules
*'''Cathedral of the Faithful:''' Each Section on a CAS can replace '''ONE''' of its listed Boarding Craft with a [[Zealot]] for NO POINTS! This bonus is in addition to the standard number of Zealots available to a Fleet.
*'''Seraph Hosts:''' All [[Seraph]] Interceptor Wings launched by a CAS increase their maximum size to '''6''' rather than the normal '''5'''.
*'''Limited Resources:''' All CAS exist as individual Battle Groups and are not required to follow the standard rules for Battle Group creation. Whilst they are not Specialist Battle Groups, they are restricted by the size of the Fleet they are attached to. Therefore a single CAS can be included in a Fleet for every '''FULL 1250''' Points being played.

==Production notes==
''Syfon''-pattern assault carriers were first introduced into the series as the assault carrier design featured in ''[[Halo 2: Anniversary]]'', serving as the canon designs for the ships featured in that game. They were later heavily featured in the ''[[Halo: Fleet Battles|Fleet Battles]]'' tabletop game and the ''[[Halo Encyclopedia (2022 edition)]]''. Various alternate depictions, such as the [[Terminal (Halo 2: Anniversary)|Terminals]] or ''[[Halo: Spartan Strike]]'' cutscenes produced by [[Sequence]], have depicted the ship in its original ''Kerel'' design - though these are considered artistic license.
