It was informally referred to as the ''Autumn'', and, in some cases, the ''Pillar''.<ref>'''Halo: The Flood''', ''page 13''</ref><ref>'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]'' (objective description)</ref><ref>'''Halo: First Strike''', ''page 103''</ref> It was the sister ship of {{UNSCShip|Dawn Under Heaven}}<ref name="interview">[http://halo.bungie.net/News/content.aspx?type=topnews&cid=6 '''Bungie.net''': ''Jason Jones Interviewed By You'' (12/18/2001)]</ref> and {{UNSCShip|Toulouse}}.<ref name="canon fodder">[https://www.halowaypoint.com/en-us/news/rockin-railin '''Halo Waypoint''': ''Halo Community Update - Rockin' & Railin{{'}}'']</ref>

Prior to the [[Fall of Reach]] ''Pillar of Autumn'' was selected to support [[Operation: RED FLAG]], a [[SPARTAN-II program|SPARTAN-II]] mission to capture [[Covenant]] [[Hierarchs|leaders]]. [[UNSC rank structure#Officer ranks|Captain]] [[Jacob Keyes]] was placed in command. The operation was forestalled by the Covenant assault on Reach; the cruiser carried some of the few UNSC survivors and fled the system having lost most of its intended SPARTAN-II passengers.

The cruiser was guided to the [[Soell system]] by the [[smart AI]] [[Cortana]]. There it was engaged by a [[Fleet of Particular Justice|Covenant fleet]] guarding [[Installation 04]]. Keyes crash-landed the ship on the installation where the surviving crew continued the battle against the Covenant, and later, the [[Flood]]. The ship's sole remaining combat-effective SPARTAN-II, [[John-117]], was forced to destabilize the ''Autumn''{{'}}s fusion reactor, destroying both the ship and the ringworld, to prevent the Installation from being fired. 

==History==

===Construction===
UNSC ''Pillar of Autumn'' was constructed at the [[Reyes-McLees Shipyards]] on [[Mars]]. The ship began construction in [[2507]],{{Ref/Reuse|Mythos95}} and was launched on [[2510|December 1, 2510]].<ref name= "data drop"/>

===Human-Covenant War===
{{Main|Battle for Arcadia}}
During the [[Battle for Arcadia]] in [[2531|February 2531]], ''Pillar of Autumn'' engaged two {{Pattern|Ket|battlecruiser}}s alongside the {{UNSCShip|Belfast}}, {{UNSCShip|Texas}} and {{UNSCShip|Armstrong}}. Along with the other three ships, ''Pillar of Autumn'' destroyed the battlecruiser designated ''[[CCS-U321]]'' after catching it with its shields down, but the battlecruiser designated ''[[CCS-U624]]'' was able to make it to the surface of [[Arcadia]]. In the battle between the UNSC and Covenant forces, ''Pillar of Autumn'' was badly damaged along with ''Armstrong'' while ''Texas'' and ''Belfast'' were destroyed. Upon the arrival of the {{UNSCShip|Spirit of Fire}}, the [[smart AI]] [[Serina]] reported on these events to Captain [[James Cutter]].{{Ref/Level|HW|[[Arcadia City]]}} Later in the battle, at the request of ''Spirit of Fire'', ''Pillar of Autumn'' contributed several [[M145D Rhino]]s to the ground battle, enabling ''Spirit of Fire''{{'}}s forces to take down a Covenant energy shield.<ref name="H:W_DomeOfLight">'''Halo Wars''', level ''[[Dome of Light]]''</ref>

The cruiser was decommissioned with the remaining {{class|Halcyon|light cruiser}}s, but was reactivated as the war worsened. ''Pillar of Autumn'' was pulled from long-term storage and was refitted in [[2550]] to serve as an emergency support ship in a conflict near [[Zeta Doradus]].{{Ref/Reuse|HCESGuide}}<ref name="for238">'''Halo: The Fall of Reach''', page 238</ref>

===A chariot for Spartans===
By [[2552]], it was obvious to the UNSC that the war could not be ended with conventional military action. A desperate plan, known as [[Operation: RED FLAG]] was conceived to end the war by capturing Covenant leaders and forcing the enemy to the negotiating table. [[Reach|A colony world]] would be sacrificed to the Covenant to allow SPARTAN-II commandos to board and disable a Covenant ship, locate the Covenant [[High Charity|homeworld]], and abduct the targets. ''Pillar of Autumn'' was selected on August 25 by the AI Cortana to disable an enemy ship and deliver the Spartans aboard; the ship was selected for the ''Halcyon''-class's durability, despite its class's usual lack-luster offensive capabilities.<ref>'''[[Halo: The Fall of Reach]]''', page 238 (''"...At the time, deemed unnecessarily over massed and costly due to series of cross-bracing and interstitial honeycombs... Halcyon-class ships, however, have a reputation for being virtually indestructible. Reports indicate these ships being operational even after sustaining breaches to all compartments and losing ninety percent of their armor."'')</ref> Command of the ship was given to [[Jacob Keyes|Captain Jacob Keyes]].

The cruiser received another refit designed by Senior Engineer Adam Crokett for the new mission, including a state-of-the-art fusion power plant and improved weaponry.{{Ref/Reuse|for238}} Furthermore, the command bridge was upgraded with a Tier III datacore to house Cortana and the drop pod bays were significantly expanded.{{Ref/Reuse|Warfleet}} After the refit, Cortana was transferred to handle the shakedown.

===Fall of Reach===
{{main|Fall of Reach}}
[[File:HM-PoA-escape.jpg|300px|thumb|''Pillar of Autumn'' pushes through the Covenant blockade and escapes Reach.]]
''Pillar of Autumn'' was prepared to deploy on August 30. However, before it could depart the [[Epsilon Eridani system]] it was recalled to Reach; the UNSC fleet was mustering in preparation for an imminent Covenant attack on the planet. However, Cortana remained in control as the ship's normally assigned AI was not yet operational. At the opening of the battle, the ''Pillar of Autumn'' was engaged by a {{Pattern|Ruma|light carrier}} and quickly destroyed it with its modified MAC gun.

It was hoped an opportunity to capture an enemy ship would present itself, however, the course of the battle forced the Spartans to deploy on other missions. [[Blue Team]] went to Reach's [[Gamma Station]] to enforce the [[United Nations Space Command Emergency Priority Order 098831A-1|Cole Protocol]], while [[Red Team]] went planetside to reinforce the [[orbital defense generator]]s. While the cruiser performed well, the battle was lost as the [[orbital defense platform]]s fell silent. There was only time to recover the remnants of Blue Team (John-117 and the clinically dead [[Linda-058]]) and a Marine fireteam led by [[Avery Johnson]] that was also onboard Gamma Station, before the ship was forced to flee the system.

During the battle over Reach, the ''Pillar of Autumn'' attacked and destroyed a [[Kewu-pattern battleship|Covenant "sniper ship"]] in single combat. This prototype vessel was responsible for the destruction of many powerful UNSC warships. The unlikely victory of the ''Pillar of Autumn'', for a brief moment, left her as one of the most successful and resilient ships in the Navy. However, the ship was heavily damaged in the fight and its main reactor was rendered inoperable.

{{Main|Battle of Asźod}}
At some point during the conflict, the ''Pillar of Autumn'' executed a [[Class-L flash-dock]], landing at the [[Asźod ship breaking yards]] to rescue any survivors on the planet and retrieve [[Cortana|a package]] which the remnants of [[NOBLE Team]] were tasked with delivering.<ref>'''Halo: Reach''', campaign level ''[[The Package]]''</ref> During [[Battle of Asźod|the battle]], as NOBLE Team approached, the ''Pillar of Autumn'' used its point-defense guns to help clear the skies and sent forces into the drydocks to hold them. When [[SPARTAN-B312|Noble Six]] and [[Emile-A239]] arrived, Emile manned an [[Mark 2488 Magnetic Accelerator Cannon|Onager mass driver]] set up by the UNSC forces to hold off the Covenant air support. After the UNSC forces took out Covenant attackers on a landing platform, Keyes personally led a Pelican to get the package. However, Emile was killed by a [[Sangheili Zealot]] and a {{Pattern|Ket|battlecruiser}} arrived to prevent the ''Pillar of Autumn'' from escaping. Using the mass driver, Noble Six destroyed the battlecruiser and the ''Pillar of Autumn'' was able to escape into space using [[R7 thrust coupling]]s.<ref>'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref>

[[File:H2A - Autumn.jpg|300px|left|thumb|''Pillar of Autumn'' prior to making a slipspace jump.]]
The ''Pillar of Autumn'' was supposed to have made a random [[Slipstream space|Slipspace]] jump in accordance with the Cole Protocol. However, Cortana surreptitiously guided the ship to the [[Soell system]] and, ultimately, to [[Installation 04]] instead. The AI used coordinates obtained from two [[Forerunner]] artifacts: [[Sigma Octanus IV artifact|one]] on [[Sigma Octanus IV]],<ref>'''Halo: The Fall of Reach''', Epilogue, page 336</ref> and [[Babd Catha Forerunner complex|one]] underneath [[Reach]]. The Covenant pursued along the cruiser's exit vector and arrived at Soell first with a battle group of {{Pattern|Ket|battlecruiser}}s.

===Battle of Installation 04===
[[File:Autumn Arrival.png|thumb|250px|''Pillar of Autumn'' approaches Halo [[Installation 04]].]]
{{main|Battle of Installation 04}}
''Pillar of Autumn'' was almost immediately engaged upon arriving at Threshold. The [[Prophet of Stewardship]], who feared stray [[plasma turret|plasma torpedo]] fire might damage the holy artifact, ordered the boarding and capture of the cruiser. Fleet Master [[Thel 'Vadamee]] ignored this order and returned fire aggressively. Even so, the ''Autumn'' was able to destroy four ships and damage ''[[Truth and Reconciliation]]'' before boarders disabled its [[Magnetic Accelerator Cannon]] with an [[antimatter charge]].

Captain Keyes ordered the crew to abandon ship. John-117 was given Cortana for safekeeping, and ordered to keep the AI out of enemy hands. The crew left the ship for the ring in whatever craft were available and the [[cryo-chamber|cryo pods]] were jettisoned. Keyes directed ''Pillar of Autumn'' on a course to crash land on the ring. The Covenant finally began hitting the ship with plasma torpedoes, but the cruiser survived the landing reasonably intact, though damaged beyond repair. The Covenant soon swarmed the ship and installed a security detail of two Banshees and six Ghosts to patrol the ship, though a massive [[Raid on the Pillar of Autumn|raid]] led by Lieutenant [[Melissa McKay]] unseated the Covenant from the ship temporarily, allowing the survivors to transfer supplies from the ship to [[Alpha Base (Installation 04)|Alpha Base]].<ref>''Halo: The Flood, chapter six''</ref>

[[File:AutumnMawCEA.jpg|thumb|left|250px|The ''Autumn''{{'}}s final resting place, shortly before its destruction.]] 

The release of the Flood added an unexpected dimension to the battle. [[Monitor]] [[343 Guilty Spark]] was preparing to fire the Installation in response to the outbreak; in conjunction with the entire [[Halo Array]] this would wipe out all sentient life in the galaxy. John-117 and Cortana returned to ''Pillar of Autumn'' to destroy the ring by detonating the still-functioning fusion reactors. An attempt to activate the cruiser's self-destruct from the bridge failed due to 343 Guilty Spark's interference. The Spartan was forced to manually destabilize the reactors with tactical ordnance.

John-117 and Cortana escaped the subsequent detonation and the ring aboard a [[GA-TL1 Longsword|Longsword fighter]] still docked in [[Launch Bay 7]]. ''Pillar of Autumn'' exploded moments after their escape, blowing up a segment of the ring causing the entire Halo to fall apart; ultimately destroying Installation 04. The detonation itself left a huge crater, almost covering the entire width of the Installation itself.

===Legacy===
[[File:H2A-AlphaHaloDestruction.jpg|thumb|300px|Installation 04 breaks apart as a result of the ''Autumn''{{'}}s detonation.]]
The {{Class|Autumn|heavy cruiser}}, which entered service as the replacement for the {{Class|Marathon|heavy cruiser|}} after the Covenant War, was partially designed after the refitted ''Pillar of Autumn''. Due to the instrumental role the ''Autumn'' played in the war, the lead ship of the new class was named {{UNSCShip|Pillar of Autumn II}} in honor of the original.<ref name="VIS">'''[[Halo 4: The Essential Visual Guide]]''', ''page 191''</ref>

In [[2556]], a fragment of the ring that escaped destruction called [[Alpha Shard]] was discovered. The [[supernova]]-like effects of the ''Autumn's'' detonation created [[Element 120.V|a new element]] unique to the shard fatal only to humans. This element was mined by smugglers from [[Aleria]] and transformed into a [[bioweapon]] [[Terrorist attack on Sedra City|used]] on the [[Outer Colony]] of [[Sedra]] by [[terrorist]]s. After the element was traced to Alpha Shard, Private [[Talitha Macer]] correctly surmised that the element was created by the explosion created when the ''Pillar of Autumn'' was destroyed. After this theory was confirmed, a joint [[ONI]]-[[Sedran Colonial Guard]] team underwent [[Mission to Alpha Shard|a mission]] to Alpha Shard, destroying the deposits of the new element with a [[HAVOK tactical nuclear weapon]] at the cost of most of the team.<ref name="Nightfall">'''[[Halo: Nightfall]]'''</ref>

==Design details==
[[File:HWF PillarOfAutumn CrossSection.jpg|thumb|left|300px|A cross-sectioned view of the ''Pillar of Autumn''.]]
''Pillar of Autumn'' was roughly 43 years old at the time of its escape from Reach and later destruction on Installation 04. It was a cruiser of the ''Halcyon''-class, the lightest cruisers in the UNSC Fleet.<ref name="page238">'''Halo: The Fall of Reach''', page 238, (''"The Pillar of Autumn is forty-three years old," Cortana said. "''Halcyon''-class ships were the smallest vessel ever to receive the cruiser designation. It is approximately one-third the tonnage of the [[Marathon-class heavy cruiser|''Marathon''-class]] cruiser currently in service."''</ref> 

The internal superstructure of ''Pillar of Autumn'' was designed by [[Robert McLees (ship designer)|Doctor Robert McLees]], though it was deemed unnecessarily over-massed and costly due to a series of cross-bracings and interstitial honeycombs. This led to the design being dropped from future models of ''Halcyon''-class ships. ''Pillar of Autumn'' and 10 others out of 50 were built with this type of superstructure. The internal bracing structure allowed the ship to function even after sustaining critical levels of damage.{{Ref/Reuse|HCESGuide}} Furthermore, the ship was fitted with an intraship transit system, which consisted of a network of lifts, stairs, and mag-rail platforms.

Following a refit in 2552, the ''Autumn'' substantially expanded its [[SOEIV]] launch bays, while the hull was upgraded to the latest Titanium-A ablative armor plating. Protruding from its front face is a foremast that is equipped with [[slipspace]] navigation sensors and hardened [[proselytization network]] transponders. A planetary scanning array is mounted just below its Omega-pattern bridge, which is outfitted with planetary survey sensors and probe/satellite launchers. Four compact auxiliary fusion rockets are installed on either side of the cruiser, and while they are capable of a high-thrust, they are considered inefficient in their design. At the very top of the engine cowling is a multipurpose scan array, which contains tactical sensors and an electronic eavesdropping suite.{{Ref/Reuse|Warfleet}}

===Power plant===
[[File:POA Panorama.jpg|thumb|250px|The refitted ''Pillar of Autumn''.]]
Prior to being refit for the Spartan mission, ''Pillar of Autumn'' was equipped with three Mark II Hanley-Messer deuterium [[Fusion drive|fusion engines]], which supplied only 10% the power of the standard [[2552]] UNSC Navy reactor. ''Pillar of Autumn'' was refitted with a set of improved nuclear fusion engines that featured two smaller reactors around a larger one, which were capable of boosting the overall power output by 300% for a short time if needed.{{Ref/Reuse|for274}}

Fusion reactors generate extreme heat which must be removed in order for them to remain active without overheating. The Autumn's overhauled reactors were an especially severe case of this. Usually, the excess heat was conducted to a chemical agent which would then vent into space. However, the ''Autumn''{{'}}s upgraded specifications also included an upgraded cooling system, which featured a "laser-induced optical slurry of ions chilled to near-absolute zero", which was far more efficient than the typical method and removed the reliance on expendable chemical temperature-control substances. In essence, the amount of excess heat removed by the new system increased as the reactors' output did. This self-regulating and self-cooling power plant was critical in combat since it virtually eliminated a commander's concerns about overheating and slagging a ship's engines.{{Ref/Reuse|for274}}

''Pillar of Autumn's'' reactors were able to be [[Fusion drive#Use as improvised weapons|overloaded by explosives]], either grenades or rockets, destroying the vulnerable vent cores. Once these were destroyed, the reactors began to go critical, resulting in temperatures of over 100,000,000 degrees and a thermonuclear explosion large enough to tear apart a Halo installation.<ref>'''[[Halo: Combat Evolved]]''', campaign level ''[[The Maw (Level)|The Maw]]''</ref> This explosion was later revealed to be similar in nature to a [[supernova]] and resulted in the creation of [[Element 120.V|a new element]] on [[Alpha Shard|a surviving shard]] of the installation.{{Ref/Reuse|Nightfall}}

===Armament===
Prior to being refit for the Spartan mission, ''Pillar of Autumn'' had just one regular MAC gun and six Archer missile pods.{{Ref/Reuse|page238}} The upgraded ''Pillar of Autumn'' received extensive refits, including several to its weapons systems. Eventually, it was host to a very powerful armament; far in excess of the original ''Halcyon''-class ships. 

*With extra power capacitors and power recycling systems, ''Pillar of Autumn's'' MAC gun could fire three consecutive shots per charge.
*The '''[[Magnetic Accelerator Cannon|Mark II, Light Coil - 56A2D4/MAC gun]]'''{{Ref/Reuse|waypointarticle}} that ran two-thirds the length of the cruiser{{Ref/Reuse|Warfleet}} fired lighter projectiles compared to most ship grade MACs, but these rounds worked much like [[shredder round]]s. Each charge was able to fire 3 rounds.
*Thirty-Two '''[[Archer missile#M58 Archer|M58 Archer missile]] pods'''.{{Ref/Reuse|Warfleet}}
*Four '''[[Shiva-class nuclear missile]]s''', one loaded onto a remote-controlled Longsword interceptor, and three ship-launched.<ref>'''Halo: The Fall of Reach''', Chapter 29, page 275 (''"In response to [[Captain Keyes]]' question about the small single ships in the launch bay, [[Lieutenant]] [[Aki Hikowa|Hikowa]] states, "Yes Sir. One of the Longswords is equipped with a [[Shiva-class nuclear missile]]; it can be remote piloted. We also have three HAVOC Warheads on board"'').</ref>
*Eighteen '''[[M910 Rampart point defense network|M910 point defense gun]]s''' with overlapping fields of fire for point defense against single ships. Two of these cannons were later salvaged by the surviving UNSC personnel for [[Alpha Base (Installation 04)|Alpha Base]].{{Ref/Reuse|Warfleet}}

===Engine room===
{{#widget:Vimeo|id=285590020|thumb|width=200px|caption=The Pillar of Autumn burning up in Installation 04's atmosphere.}}
{{main|Fusion drive}}
''Pillar of Autumn''{{'}}s engine room was a large, three-deck high chamber allowing access to the fusion engine core. Side passages allowed for movement from the bottom deck all the way up to the catwalks on the third. The manifolds into the cores were suspended above the second deck. Controls on the third retracted these manifolds, exposing a vent that led directly into the core. It was using this method to expose the core via the vents that the John-117 ultimately destroyed the ship and Installation 04. This room is the largest room in ''Pillar of Autumn'' with the exception of the hangar bay and the "leap of faith" room.

===Airlocks===
:'''Airlock 31, 32''': Lifeboats destroyed by the Covenant to make way for boarding craft.
:'''Airlock 51''': Lifeboat destroyed as it departed from the airlock.
:'''Airlock 52, 53, 61, 62, 63''': Lifeboats escaped from the vessel.

==Units==
[[File:HR Autumn Longsword.png|thumb|250px|A Longsword flanking the drydocked ''Autumn''.]]
===Marine units===
The ''Pillar of Autumn'' had a complement of eight hundred Marines and four hundred ODSTs, totaling 1,200 fighting personnel.{{Ref/Reuse|Warfleet}} The ship's Marine complement were divided into the following units;

The [[67th Marine Regiment]], [[3rd Battalion (Pillar of Autumn)|3rd Battalion]] led by Colonel [[Barry Bizzell]] may have been assigned to the ''Pillar of Autumn'', but the canon status of this unit is dubious.<ref>''Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo'' - Early revision of the ''Pillar of Autumn' page ([[:File:WF EarlyAutumn Page.jpg|file link]])</ref>{{Ref/Note|Due to this unit only being mentioned in a cut page from ''Halo: Warfleet'', the canon status of this unit is unknown.}}

===ODST units===
The ship's 400 ODSTs were divided under the following units;{{Ref/Note|In Chapter 2 of ''Halo: The Flood'', Silva sends B and C companies away for various tasks, commenting that his camp only has half of its strength left at 200 personnel This means each company has roughly 100 personnel. Later statistics given on ODST [[combat team]] organisation place ODST company sizes at 60-112 personnel, in keeping with this information.}} 

*1st Battalion{{Ref/Note|The ''Halo Encyclopedia'' pages 54-55 clarify that the twelve companies of a given regiment are named phonetically, with the first battalion taking A-D, second battalion taking E-H and so forth. Given Silva's battalion's subordinate companies are named A-D in Chapter 2 of ''Halo: The Flood'', this means they must be in the 1st battalion of the parent regiment.}} - Commanded by Major Antonio Silva.

==Trivia==
===Production notes===
*When designing the ship, [[Lorraine McLees]] took inspiration from the [[MA5B assault rifle]] and from images of ''[[wikipedia:Mobile Suit Gundam|Mobile Suit Gundam]]''. She described the ''Autumn'' as being "essentially a big gun with engines".<ref>'''Halo: The Great Journey: The Art of Building Worlds''', ''page 140''</ref>
*''Pillar of Autumn'' was modeled by former Bungie employee Adam Crokett.<ref>[http://www.adamcrockett.com/resume.html '''Adam Crockett''': ''Resume'']</ref>

===Miscellaneous===
[[File:Bulletin board compare.jpg|thumb|200px|The Bulletin Board on the ''Autumn's'' bridge in both ''[[Halo Combat Evolved]]'' and ''[[Halo: Combat Evolved Anniversary|Anniversary]]''.]]
*In ''[[Halo: The Fall of Reach]]'', the description of ''Pillar of Autumn'' is considerably different from its ''Halo: Combat Evolved'' incarnation. The bridge is described as having a command chair and a curved viewport; in ''Halo: Combat Evolved'', this chair is absent and the window consists of several flat sections. The novel also describes the bridge as being extremely cramped, with only a meter of space between the command chair and the other stations,<ref name="for277">'''Halo: The Fall of Reach''', ''page 277''</ref> while in the game, the bridge is clearly more spacious. According to the novel, there is also an elevator leading directly from the engine room to the bridge.{{Ref/Reuse|for277}} In the game, the engineering and the bridge are on the same level, and there are no doors which may belong to an elevator adjoining the bridge. In addition, the engine room is described as being "hexagonal", while in the game,{{Ref/Reuse|for274}} it consists of two vaguely rectangular chambers with the engine core in the middle. The ship is also described as having rotating centrifuges to generate [[artificial gravity]];{{Ref/Reuse|for274}} no rotating sections are present in the game, unless they are located within the hull.
*''Pillar of Autumn''{{'}}s was approximately 1.17&nbsp;km long, a reference to John-117.<ref>[http://nikon.bungie.org/misc/sloftus_poaconundrum '''halo.bungie.org''': ''The Pillar of Autumn Conundrum'']</ref> The ship's length is exaggerated in the final level of ''Halo: Combat Evolved'' to a length of three kilometers, likely to add urgency and suspense to the escape sequence.
*In ''Halo: Combat Evolved'', the ship's [[Ship emblem|emblem]] is the ''[[Marathon]]'' logo. In ''Halo: Reach'', the ship's emblem is retconned into the Seventh Column logo. In ''Halo: Combat Evolved Anniversary'', the Seventh Column emblem is replaced by a similar-looking gear, since the Seventh Column is an affiliate of Bungie. 
*The [[bulletin board]] just outside the bridge of the ship contains a number of amusing clips, some throwbacks to ''Marathon''. These can be examined on the first level of ''Halo: Combat Evolved''. The board has a flier for a missing cat called [[Jonesy]]. This is a reference to the ''Alien'' movies, where the cat's name was Jonesy. The board also has a flier telling Marines to [[Keep It Clean (Trailer)|'Keep it Clean']], a quote later used in ''[[Halo 3: ODST]].''
**The re-textured bulletin board in ''[[Halo: Combat Evolved Anniversary]]'' includes a classic Internet gag image of a "cat found" poster mistaking an opossum for a cat, as well as a poster labelled "Dark Planetoid Rising", featuring the Forerunner planet [[Requiem]] as it appeared in the Legendary ending to ''[[Halo 3]]''.
*During the brief cutscene in ''[[Halo 2]]'' where ''Pillar of Autumn'' escapes, it is portrayed by a ''Marathon''-class heavy cruiser, rather than a ''Halcyon''-class light cruiser; this is because the ''Halcyon'' was not coded into the game for the sake of saving resources; this error is rectified in ''Halo 2: Anniversary''. 
*In its appearance in ''[[Halo: Reach]]'', the ship went through many changes, including that the Marathon symbol is replaced by the Seventh Column symbol, and the bridge has been shrunken to a smaller scale.
*''Pillar of Autumn'' is available as a prop for [[Avatar (Xbox 360)|Xbox 360 Avatars]].<ref>[http://halo.xbox.com/blogs/Headlines/post/2012/01/18/Halo-Avatar-Collection-January.aspx '''Halo: Waypoint:''' ''Halo Avatar Collection - January'']</ref>
*''Pillar of Autumn'' plays a role in ''[[Halo: Combat Evolved]]'', ''[[Halo Reach]]'' and ''[[Halo Wars]]''. In the first two, the player has to deal with various objectives surrounding the ship and crew. In ''Halo Wars'', ''Pillar of Autumn'' contributes to the [[Battle for Arcadia]] before the {{UNSCShip|Spirit of Fire}} arrives and then provides the player with support during the battle in the form of experimental [[M145D Rhino|Rhinos]].
*Although total deck count is unknown, there are a minimum of 75 decks on the ''Pillar of Autumn'', as indicated by the [[Bulletin board|Bulletin Board]] note ''Cat Found'' found near the ships bridge.
