'''UNSC ''Infinity''''' ([[Hull classification symbol|INF-101]]) is an experimental [[Infinity-class supercarrier|''Infinity''-class supercarrier]] of the [[UNSC Navy]] commissioned following the end of the [[Human-Covenant War]].{{Ref/Reuse|wf infinity}} Built in secret utilizing technology recovered from [[Forerunner]] and [[Covenant]] sources during the war, ''Infinity'' is the UNSC's largest and most advanced multi-role vessel to date.{{Ref/Reuse|Glasslands 422}} ''Infinity'' serves under the direction of [[Fleet Command]] and was originally captained by [[Andrew Del Rio]], and later [[Thomas Lasky]].<ref>[https://www.halowaypoint.com/en-us/universe/vehicles/infinity '''Halo Waypoint''': ''UNSC Infinity'']</ref> She is the current designated [[flagship]] of [[Expeditionary Strike Group 1]] and serves as the ceremonial flagship for the United Nations Space Command.{{Ref/Reuse|lootcrate1}}

The first ship of her class, ''Infinity'' was secretly deployed in combat in [[2553#March|March 2553]]. On [[2557|February 21, 2557]],{{Ref/Reuse|packet}} the vessel was officially commissioned after being refitted with technology that would add scientific and diplomatic endeavors to her capabilities.<ref name="Commissioning">'''The Commissioning'''</ref><ref>[http://www.halowaypoint.com/en-US/halo4guide '''Halo 4 Interactive Guide''': ''Captain Andrew Del Rio biography'']</ref> By [[2558|February 2558]], ''Infinity'' had a crew of 17,151 sailors, [[UNSC Marine Corps|Marines]], ONI operatives, and civilian personnel, as well as numerous adjunct members of the other UNSC branches and a number of [[Huragok]] specialists.{{Ref/Reuse|packet}}<ref>'''Halo: The Thursday War''', ''page 48''</ref> ''Infinity'' may additionally embark an escort force of ten internally-docked [[Strident-class heavy frigate|''Strident''-]] and later {{Class|Anlace|frigate|frigates}}.{{Ref/Reuse|packet}}{{Ref/Reuse|Departure}}<ref name="A Hero Awakens">'''[[Making Halo 4: A Hero Awakens]]'''</ref> As of [[2558#October|October 2558]], the primary shipboard AI is [[Roland]].{{Ref/Reuse|Guardians}}<ref>'''Halo 4: The Essential Visual Guide''', ''page 192''</ref> The ship's motto is ''Audere Est Facere'' (''To Dare is to Do'').{{Ref/Reuse|Mythos132}}

===Construction===
{{Quote|This is the culmination of human achievement.|UNSC dignitary{{Ref/Reuse|Commissioning}}}}
[[File:Commissioning-5.jpg|thumb|left|250px|''Infinity'' during her commissioning ceremony.]]
Authorised as an emergency mobile colony by [[Project OUROBOROS]],{{Ref/Reuse|wf infinity}} the ship was constructed in the [[Special Assembly Plant Concord]] located in the [[Oort cloud]] surrounding the [[Sol system]],{{Ref/Reuse|Glasslands 422}} with construction beginning in [[2544]].{{Ref/Reuse|Mythos132}}<ref name="Infinity trailer">[http://www.youtube.com/watch?v=PsNWkjP65Cg '''YouTube''': ''Halo 4 Infinity Multiplayer'']</ref> The ship was designed by a team composed of [[Elizabeth Sark|Vice Admiral Elizabeth Sark]], [[Oscar Greyson|Commander Oscar Greyson]], and [[Dana Wolff|Doctors Dana Wolff]] and [[Sada no Okuni]].{{Ref/Reuse|wf infinity}} Secrecy was ensured by having workers permanently stationed there over several years with a total communications blackout in effect. The ship's massive building expenditures, however, prevented ONI from keeping the ''Infinity'' a complete secret. Many senior members of the Admiralty, such as [[Saeed Shafiq|Rear Admiral Saeed Shafiq]] of [[UNSC Procurement]], were fully aware of the ship's existence at the time of her construction.<ref name="Glasslands 390">'''Halo: Glasslands''', ''page 390''</ref> Eventually the Fleet took control of the vessel rather than the [[Office of Naval Intelligence]]. Captain Andrew Del Rio took command of the ship and her pre-commission crew years prior to the end of major hostilities in the war,{{Ref/Reuse|Glasslands 422}} though [[Commander-in-Chief of the Office of Naval Intelligence|CINCONI]] [[Margaret Parangosky]] correctly predicted that [[Thomas Lasky|Commander Thomas Lasky]] would eventually supplant Del Rio.<ref>'''Halo: The Thursday War''', ''page ???''</ref>

===Insurrectionist attack===
{{Main|Raid on UNSC Infinity}}
A small number of [[SPARTAN-IV program|Spartan-IVs]] from the new program's first official class were assigned to ''Infinity'' in January 2553. Shortly afterward, [[Insurrectionist]]s led by the former Spartan-IV [[Ilsa Zane]] attempted a hostile takeover of the vessel, entering the ship disguised as a construction crew.<ref name="HI2">'''[[Halo: Initiation]]''', ''[[Halo: Initiation Issue 2|Issue #2]]''</ref> The attack was repelled, largely due to the efforts of Spartans [[Sarah Palmer]] and [[Edward Davis]]. This incident exposed [[Admiral]] [[Mattius Drake]] as the leader of the [[New Colonial Alliance]], and the Spartan-IVs' actions contributed to the establishment of the Spartans as [[Spartan Operations|their own branch of service]].<ref>'''Halo: Initiation''', ''[[Halo: Initiation Issue 3|Issue #3]]''</ref> Additional Spartans were included in the ship's contingent as time progressed{{Ref/Reuse|Glasslands 422}}<ref name="Game Informer 52012">'''Game Informer''' ''(May 2012)'', ''pages 46-47''</ref> and Palmer would later become the commanding officer of the ship's Spartan complement.<ref name="Avatar">[http://marketplace.xbox.com/en-GB/Product/Commander-Palmer-Armor/00000ffc-69a7-f211-c9c0-33834d530919 '''Xbox.com''': ''Commander Palmer Armor'']</ref>

===Sanghelios===
{{Quote|Think of it as a work-up exercise. A Thursday War.|[[Admiral]] [[Margaret Parangosky]]<ref>'''Halo: The Thursday War''' ''page 69''</ref>}}
With a number of further upgrades to the ship, the ''Infinity'' was launched on [[2553#March|March 22, 2553]], with Del Rio at the helm.<ref>'''Halo: The Thursday War'''</ref> In March, ''Infinity'' underwent inspection by [[Admiral]]s [[Terrence Hood]] and [[Margaret Parangosky]]. By this time many crew changes had been enacted on the ship. [[Catherine Halsey|Dr. Catherine Halsey]] was put to work installing the ship's [[Forerunner]] slipspace engines, under the supervision of Dr. [[Henry Glassman]], the chief engineer. Many [[Huragok]] from [[Trevelyan]] had been assigned to the ship, led by [[Requires Adjustment]]. [[Aine]] was assigned to the ship as a temporary AI.<ref>'''Halo: The Thursday War''' ''page 45-53''</ref> Parangosky met with Del Rio and Lasky, who discussed the current refit shape of ''Infinity''.<ref>'''Halo: The Thursday War''' ''page 65''</ref> While aboard the ship, Parangosky and Hood received intel on the ongoing [[Blooding Years]], learning that [[Vadam Keep]], the headquarters of [[Arbiter]] [[Thel 'Vadam]], was about to be breached by the [[Servants of the Abiding Truth]]. Hood contacted Vadam, who reluctantly agreed to accept Hood's help. After Glassman cleared the ship for combat, it departed for Sanghelios.<ref>'''Halo: The Thursday War''' ''page 235''</ref>

When ''Infinity'' arrived over Sanghelios, [[Kilo-Five]]'s [[prowler]] {{UNSCShip|Port Stanley}} docked with the ship, and Parangosky gave [[Captain (Navy)|Captain]] [[Serin Osman]] two Huragok, Requires Adjustment and [[Leaks Repaired]], who made several refits to Kilo-Five's Pelican ''[[Tart-Cart]]''.<ref>'''Halo: The Thursday War''' ''page 265''</ref> Soon, the [[Sangheili]] opposition ship ''[[Defender of Faith]]'' began to assault Vadam; the Elite vessel was easily destroyed.<ref>'''Halo: The Thursday War''' ''page 303''</ref> The remaining Sangheili insurgent forces were all but destroyed when ''Infinity'' fired her fore MAC gun on their positions, creating a massive crater on the Vadam coastline. Due to ''Infinity''{{'}}s help in the battle, Vadam was saved and the battle trial was considered successful. Kilo-Five later rejoined the ship's crew.<ref>'''Halo: The Thursday War''' ''page 361''</ref>

===First tour on Requiem===
{{Main|Battle of Requiem}}
[[File:H4-E3-Campaign-4.jpg|thumb|250px|[[John-117]] watches as ''Infinity'' is pulled into Requiem.]]
The UNSC officially commissioned ''Infinity'' into service, publicly refocusing her mission on peace and exploration, on February 21, 2557. The following year, this date would be commemorated as "''Infinity'' Day".{{Ref/Reuse|packet}} ''Infinity'' was tasked with finding the rest of the Halo Array, and the UNSC forces managed to set up bases on Installation 03 as well as Installation 05 for studying and decommissioning the ringworlds.<ref name="level">'''Halo 4''', campaign level ''[[Infinity (level)|Infinity]]''</ref> Furthermore, the ''Infinity'' was used to transport a massive Forerunner artifact known as the [[Composer]] to ''[[Ivanoff Station]]'', a research station in orbit of Installation 03. After an ONI team at ''Ivanoff Station'' vanished while researching the Composer, the ship's crew learned the location of the [[shield world]] [[Requiem]].{{Ref/Reuse|level}} During the approach to Requiem, ''Infinity'' picked up a distress call from the {{UNSCShip|Forward Unto Dawn}} and her two surviving crew, [[SPARTAN-II Program|Spartan]] [[John-117]] and his [[smart AI]] companion [[Cortana]]. During the attempted rescue, the ship's control systems were hacked by the [[Didact]], the leader of the Forerunners' [[Promethean]] [[Warrior-Servant]]s, which caused it to crash-land on the shield world's surface.{{Ref/Reuse|Commissioning}} The Master Chief rallied scattered reconnaissance personnel and was soon reunited with Commander Lasky, whom he had met decades prior during the [[Battle of Circinius IV]].{{Ref/Reuse|level}}

Promethean and [[Jul 'Mdama's Covenant|Covenant]] forces boarded ''Infinity'' while the Didact scoured the ship's mainframe; though the ship's crew did not know at the time, he was searching for the location of the Composer. The Master Chief quickly brought ''Infinity''{{'}}s point defenses back online, enabling her to destroy two {{Pattern|Zanar|light cruiser}}s and to drive off the Didact's [[Cryptum]]. Shortly thereafter, Captain Del Rio ordered that [[Gypsy Company]] neutralize a network of [[particle cannon]]s that were suppressing UNSC aircraft in the area; this would allow an approach to the gravity well generator that was keeping ''Infinity'' inside the shield world, which in turn would allow the ship to return to Earth to report their findings.<ref name="Reclaimer">'''Halo 4''', campaign level ''[[Reclaimer (level)|Reclaimer]]''</ref>

After their return to the ship, John-117 and Cortana told Del Rio that they had encountered an imprint of the [[Librarian]]; John insisted that the ship pursue the Didact before he could leave Requiem. Dismissing their claims as the result of [[rampancy]] and age, Del Rio ordered that Cortana be removed from service after she temporarily—and accidentally—disabled some of the ship's systems in a fit of rage. The Master Chief refused, and the bridge crew defied the captain's order to arrest the Spartan. Lasky then provided John a [[G79H-TC Pelican|Pelican gunship]], requisitioning it under the pretense that it would be used to apprehend the Spartan. John jumped ship in the Pelican as ''Infinity'' escaped the shield world with Del Rio ordering a warning beacon dropped and a course set in for [[Carinae Station]]. Though John and Cortana were initially successful even without ''Infinity''{{'}}s help, a fit of rampancy caused Cortana to release the Didact's Cryptum from its impromptu containment structure. This allowed the Cryptum to interface with the Didact's ship, ''[[Mantle's Approach]]'', after which the Didact set course for Installation 03 while John and Cortana pursued the Didact aboard a Covenant [[Lich]].<ref name="Shutdown">'''Halo 4''', campaign level ''[[Shutdown]]''</ref>

===Stopping the Didact===
{{Main|New Phoenix Incident}}
[[File:H4-Infinity-Mantle.jpg|thumb|left|250px|''Infinity'' facing down the Didact's flagship, ''[[Mantle's Approach]]''.]]
Upon ''Infinity''{{'}}s return to Earth, Del Rio was relieved of command due to his abandonment of the Master Chief on Requiem. Lasky took over as commanding officer, just as Admiral Parangosky had planned.<ref name="Midnight">'''Halo 4''', campaign level ''[[Midnight]]''</ref> In the meantime, the Didact acquired the Composer from ''[[Ivanoff Station]]'' near Installation 03 and integrated it into ''Mantle's Approach''.<ref>'''Halo 4''', campaign level ''[[The Composer]]''</ref>

When the ship arrived in Earth's orbit, ''Infinity'' stood ready as the flagship of [[Battlegroup Dakota]], a detachment of the [[UNSC Home Fleet]]. SPARTAN-117 informed now-Captain Lasky that he intended to detonate a [[HAVOK tactical nuclear weapon]] inside ''Mantle's Approach'', preventing the Composer from being fired against Earth. Once the ship's point-defense guns were neutralized, ''Infinity'' used two of her primary MACs to blast holes in the opposing vessel's hull. The Master Chief used one of these openings to enter the ship and eventually defeated the Didact, though not before the Composer digitized the residents of [[New Phoenix]], Arizona, [[United Republic of North America|URNA]]. The ship was successfully destroyed, at the cost of Cortana's life.{{Ref/Reuse|Midnight}} A Pelican was dispatched to retrieve the Spartan, who then spoke with Captain Lasky before having his armor removed on ''S'' Deck for the first time in almost five years.<ref>'''Halo 4''', ''[[Epilogue (Halo 4 level)|Epilogue]]''</ref>

===Second tour on Requiem===
{{Main|Requiem Campaign}}
[[File:Infinity n Frigates.png|thumb|250px|''Infinity'' being escorted by two of her sub-vessels above Requiem.]]
On [[2558#February|February 7, 2558]], ''Infinity'' returned to Requiem to clear territory for UNSC research bases. The ship and her [[UNSC frigate|sub-vessels]] quickly dispatched a small Covenant task force stationed at the entrance portal and deployed numerous dropships through the opening. A massive joint effort comprising the Navy, [[UNSC Army|Army]], [[UNSC Marine Corps|Marine Corps]], [[UNSC Air Force|Air Force]], and [[Spartan Operations|Spartans]] began securing areas on the surface from Covenant garrison forces.{{Ref/Reuse|Departure}} After a short span of time, Spartan [[Fireteam Crimson]] secured [[Requiem slipspace artifacts|a Forerunner artifact]] from an area known as "[[the Cauldron]]" and brought it aboard the ship.{{Ref/Reuse|Departure}} When the artifact began disrupting ''Infinity''{{'}}s power, artificial gravity, and propulsion, Spartan [[Sarah Palmer|Commander Sarah Palmer]] was able to disable it. Palmer, Captain Lasky, and [[Henry Glassman|Chief Engineer Dr. Glassman]] then inspected the artifact. Palmer saved Lasky from being translocated along with Glassman to Requiem by the artifact.<ref>'''Spartan Ops''', [[S1/Artifact|S1E2 ''Artifact'']]</ref> Sometime later, Dr. Halsey was brought in to examine the artifact, much to Palmer's chagrin. Due to the artifact continuously causing problems for the ship, it then was navigated by Roland, who could accomplish little without human help.<ref name="catherine">'''Spartan Ops''', [[S1/Catherine|S1E3 ''Catherine'']]</ref>

{{Main|Invasion of the UNSC Infinity}}
Some time after [[Gabriel Thorne]]'s disappearance through the translocation artifact, the ''Infinity'' was [[Invasion of the UNSC Infinity|invaded]] by large numbers of Promethean Knights, followed by Covenant forces. The Covenant created havoc on board the ship, forcing the ''Infinity'' to recall all forces on Requiem to defend the ship. Fireteam Crimson was responsible for protecting the engine and server rooms, bringing the weapons systems back online, and even deactivated multiple nuclear warheads cloaked with [[active camouflage]] stowed away on the ship, that had been earlier discovered as stolen.<ref name="Invasion">'''[[Spartan Ops]]''', [[S1/Invasion|S1E7 ''Invasion'']]</ref> It was later discovered that the primary goal of the boarding action was to kidnap Dr. Halsey for [[Jul 'Mdama]]. Despite eliminating all boarders, the ''Infinity'' remained locked above Requiem due to [[interdiction web|a slipspace anchor]] originating from the planet.<ref name="Expendable">'''[[Spartan Ops]]''', [[S1/Expendable|S1E8 ''Expendable'']]</ref>

Dr. Glassman deduced that the slipspace anchor was being generated by the Forerunner artifact aboard the ship and a pair of similar artifacts on Requiem. If the artifacts on the shield world were deactivated, ''Infinity'' would be free. At the same time, Jul 'Mdama set Requiem to collide with its sun, with the anchor pulling the ''Infinity'' along with it. Fireteams Majestic and Crimson were quickly dispatched to deactivate the artifacts, in which they succeeded. Once the two fireteams were aboard the ship, [[James (lieutenant)|Lieutenant James]] flew the ship away from Requiem on Captain Lasky's order. ''Infinity'' made an emergency jump into slipspace as the shield world was consumed by the sun, immediately sending the star into a premature [[supernova]] state. The ship emerged intact from the jump, with a number of reported injuries but no major casualties.<ref name="Exodus">'''[[Spartan Ops]]''', [[S1/Exodus|S1E8 ''Exodus'']]</ref>

===Peace talks===
{{Main|Battle of Ealen IV}}
In March 3, Fleet Admiral Terrence Hood pulled the UNSC ''Infinity'' away from the pursuit of Jul 'Mdama and assigned the ship to escort Thel 'Vadam during negotiations on [[Ealen IV]], between 'Vadam and the [[Jiralhanae]] [[Jiralhanae Chieftain|Chieftain]] [[Lydus]].<ref name="HE1">'''Halo: Escalation''', ''[[Halo: Escalation Issue 1|Issue #1]]''</ref> [[Commander (UNSC)|Commander]] [[Bradley]] had taken Lasky's former place as executive officer by this time.<ref name="HE2">'''Halo: Escalation''', ''[[Halo: Escalation Issue 2|Issue #2]]''</ref> On March 5, during the negotiations, [[Vata 'Gajat's mercenary group|Covenant forces]] led by [[Shipmaster]] [[Vata 'Gajat]] attacked the delegates.{{Ref/Reuse|HE1}} The UNSC forces on the planet were unable to contact the ''Infinity'' because the Covenant were blocking the signal.{{Ref/Reuse|HE2}} During the battle, Lasky and Spartan [[Naiya Ray]] were able to destroy the generator of the jamming signal and contact ''Infinity''. As Lasky reestablished communications, Bradley informed him that the Sangheili and Jiralhanae ships were about to attack each other. However, Lasky was able to placate the crisis and the fleets eventually rallied with ''Infinity'', forcing the Covenant fleet to retreat. The ambassadors successfully escaped the planet thanks to the sacrifices of [[Fireteam Bailey]] and [[Paul DeMarco]], which were later commemorated in a memorial service held aboard ''Infinity''.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 3|Issue #3]]''</ref>

===Freighter ambush and Oth Lodon===
{{Main|Ambush at Oth Lodon}}
[[File:Infinity attacked.... by a third time.jpg|thumb|150px|''Infinity'' is attacked by the NCA-controlled station.]]
Days later, a distress signal originating in the [[Artesia-702 system]] was picked up by ''Infinity''. When ''Infinity'' arrived in the system on March 11, it found a damaged freighter, the ''[[Pilgrims' Pride]]'', and tugged it into one of its deployment bays. An ambush was sprung within the bay when the freighter set itself to self-destruct and multiple UNSC assault crafts exited its cargo bay. With the help of Fireteams Majestic, [[Fireteam Colossus|Colossus]], and [[Fireteam Fenrir|Fenrir]], the attack was repelled and the freighter was tugged back into space before it could self-destruct on ''Infinity''. Following the skirmish, ''Infinity''{{'}}s after action teams discovered that the assault crafts from the freighter's attack were those belonging to the long-lost {{UNSCShip|Spirit of Fire}}, a warship missing since February [[2531]].<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 4|Issue #4]]''</ref>

Following the lead on ''Spirit of Fire'', Admiral Hood ordered ''Infinity'' to [[Oth Lodon]] in Jiralhanae space. Instead of the ship, ''Infinity''{{'}}s crew discovered a [[Oth Lodon station|Covenant space station]] operated by [[New Colonial Alliance]] insurgents led by Captain [[Daniel Clayton]], the illegitimate son of the ''Spirit''{{'}}s captain, [[James Cutter]].<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 5|Issue #5]]''</ref> ''Infinity'' sustained tremendous damage from three discharges of the station's [[glassing]] weapon, including starboard-to-port hull breaches and fires on the bridge; Commander Bradley was killed and Hood was paralyzed from the waist down. However, Commander Palmer and Fireteam Majestic boarded and captured the station before another blast could be fired, instead turning the weapon on Vata 'Gajat's [[Ceudar-pattern heavy corvette|corvette]] that was about to destroy ''Infinity''.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 6|Issue #6]]''</ref> After the battle, the ''Infinity'' was put under repairs and most of its staff was transferred to other duties. In mid-April 2558, over a month after the events at Oth Lodon, the ship was fully repaired.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 7|Issue #7]]''</ref>

===Bioweapon plot===
{{Main|Operation: WHISTLE STOP}}
[[File:HE12 Infinity Ven-III.jpg|thumb|250px|left|''Infinity'' retaliates against the pirates.]]
In [[2558#May|May 2558]], ''Infinity'' was involved in an ONI-commissioned mission to capture [[Ayit 'Sevi|a Sangheili]] wielding a new [[bioweapon]] on the unclaimed planet [[Ven III]]. Captain Lasky deployed a team of two Spartans, [[Gabriel Thorne]] and [[Naiya Ray]], on the planet via a [[prowler]] stored aboard ''Infinity''. After ''Infinity'' lost communications with the Spartans and a UNSC [[spy drone]] on Ven III, Roland proposed that ''Infinity'' head toward the planet. Lasky was at first hesitant to involve the ship as he had been ordered to avoid direct engagement, but after Spartan Ray discovered an enormous [[Kig-Yar]] [[pirate]] operation shortly before being ambushed, he ordered Roland to set course for Ven III and call all Spartan teams on deck.<ref name="he11">'''Halo: Escalation''', ''[[Halo: Escalation Issue 11|Issue #11]]''</ref>

Upon arriving at Ven III, ''Infinity'' was met by the pirates' advance fleet. The ship deployed several Broadswords to counter the fleet as well as a rescue convoy to retrieve the two Spartans on the surface. ''Infinity'' successfully repelled the fleet in space while [[GA-TL1 Longsword|Longswords]] took out the remaining fleet on the planet as well as the pirates' base. On the surface Ray was about to retrieve the bioweapon from the Sangheili agent but [[ONI]] agents arrived in order to retrieve the weapon themselves as well as detain the Elite agent. Thorne and Ray were successfully returned to the ''Infinity'' while Lasky and Palmer discussed ONI's intervention at the conclusion of the mission.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 12|Issue #12]]''</ref>

===The Janus Key===
{{Main|Battle of Oban|Battle of Aktis IV}}
[[File:HE13 Infinity Impact.jpg|thumb|250px|''Infinity'' runs into an asteroid.]]
Following the bioweapon incident ''Infinity'' was deployed to assist in attack against the human colony [[Oban]]. Following the battle ''Infinity'' made a slipspace jump towards [[Galileo II]] base. However the ship suddenly reappeared in an [[asteroid]] belt, colliding with an asteroid and causing some damage inside the ship. ''Infinity'' jumped to slipspace again, only to reappear a quarter of a kilometer of her last position. Roland told Captain Lasky that it is was inadvisable to make another jump. Dr. Glassman discovered ''Infinity''{{'}}s slipspace drive was overriding any coordinate except the one of the location in which they were, sticking the ship in a "Slipspace cul-de-sac". In that moment, Roland found an unusual energy reading coming from the equator of an uncharted planet — [[Aktis IV]] — near their position. Glassman and Lasky supposed that the location was the source of the problem and Palmer ordered to gather a team and send them with Dr. Glassman to the planet. Unknown to the crew, the ship had been stranded by Dr. Halsey who used a [[Requiem communication artifact|Forerunner artifact]] to contact ''Infinity''{{'}}s Forerunner components, including her slipspace drive, and trapped them in the system.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 13|Issue #13]]''</ref>

Locating the source of interference to an island on the planet, Palmer, Fireteam Majestic, and Glassman soon discovered a Forerunner artifact in a Forerunner structure. Aktis IV has an ocean consisting of an unidentified substance that was impenetrable to ''Infinity''{{'}}s sensors. After Glassman discovered that the artifact was seemingly compatible with the Janus Key, the UNSC's half of the Key was sent to the island from ''Infinity'' for further analysis. However, the UNSC aircraft carrying the key were shot down by [[Sali 'Nyon]] and his [[Sali 'Nyon's Covenant|splinter group]]. In the confusion, 'Mdama's fleet, which had avoided detection by hiding in the planet's oceans, rose up and began deploying troops. As the UNSC forces on the planet retreated into the Forerunner structure, ''Infinity'' deployed reinforcements.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 14|Issue #14]]''</ref> As 'Mdama's fleet engaged ''Infinity'' in the planet's atmosphere, the vessel could not establish contact with the UNSC forces inside the Forerunner structure. Later, ''Infinity'' succeeded in deployed at least two [[Mark IX Mantis ADS|Mantises]] to the planet's surface to battle the Covenant forces.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 15|Issue #15]]''</ref> ''Infinity'' and its ''Strident''-class sub-vessels continued to engage 'Mdama's fleet until the battle eventually drew to a close with Jul's acquisition of both halves of the Janus Key. After picking up the UNSC forces on the surface, ''Infinity'' left Aktis IV. Three days later, on July 23, ONI agents arrived onboard in order to interrogate Commander Palmer for her failure to secure the Janus Key and Dr. Halsey.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 16|Issue #16]]''</ref>

===Retrofit===
[[File:HW Infinity refit.png|thumb|left|200px|''Infinity'' undergoes refit above Earth.]]
By late 2558, ''Infinity'' had received a full systems upgrade as well as scheduled maintenance. By this time, construction on a second ''Infinity''-class vessel, the {{UNSCShip|Eternity}} had commenced. To save resources, several modules were borrowed from the incomplete ''Eternity'' to supplant those on the ''Infinity'', leading to the replacement of several non-essential weapon systems.{{Ref/Reuse|wf infinity}}

===The Guardians===
[[File:H5G-Infinity&Guardian.jpg|thumb|250px|''Infinity'' escaping a Guardian's attack.]]
In October 2558, UNSC ''Infinity'' served as mission control for both [[Fireteam Osiris]] and [[Blue Team]]. After a successful assassination of [[Jul 'Mdama]] during the [[Battle of Kamchatka]], Fireteam Osiris returned Dr. Halsey to UNSC custody aboard the Infinity.<ref>'''Halo 5: Guardians''', ''campaign level [[Osiris (level)|Osiris]]''</ref> Shortly afterward, Spartan Blue Team, led by the Master Chief, were sent from ''Infinity'' to reclaim the lost ONI research vessel ''[[Argent Moon]]'', but went AWOL after receiving a cryptic message from [[Cortana]] and denying ''Infinity''{{'}}s orders to ignore her calling to [[Meridian]].<ref>'''Halo 5: Guardians''', ''campaign level [[Blue Team (level)|Blue Team]]''</ref> With the UNSC's most veteran Spartans having deserted, Fireteam Osiris was deployed to arrest them.<ref>'''Halo 5: Guardians''', ''campaign level [[Glassed]]''</ref> Osiris returned the following day, though, without Blue Team but with an account of a [[Guardian]] awakening on Meridian's surface and Blue Team having escaped on it. Having been tracking previous and current Guardian attacks, ''Infinity'' made it their priority to track down the Master Chief by activating an inert Guardian hidden in [[Sanghelios]].<ref>'''Halo 5: Guardians''', ''campaign level [[Reunion]]''</ref>

With the aid of [[Thel 'Vadam|the Arbiter]] and the [[Swords of Sanghelios]], ''Infinity''<nowiki>'s</nowiki> forces were able to activate the Guardian and deliver Osiris aboard it.<ref>'''Halo 5: Guardians''', ''campaign level [[Battle of Sunaion (level)|Battle of Sunaion]]''</ref> Their achievement and subsequent defeat of Jul 'Mdama's remnant forces came to naught, however, as Osiris followed the Guardians to the planet [[Genesis]] and discovered the constructs were part of a plan by [[Cortana]] to put the galaxy [[Created|under the control of AIs]]. Both Master Chief and Osiris were unable to stop Cortana, and so her Guardians were released to shut down all weapons and technology across the colonies. When a Guardian was sent to pacify Sanghelios, ''Infinity'' was still in the star system but a good ways off and fled to [[Earth]] after witnessing what was happening.<ref name="BB">'''[[Halo: Bad Blood]]''', ''Chapter 1''</ref> However, when Cortana began the [[Subjugation of Earth]], ''Infinity'' was forced to make an emergency slipspace jump to avoid being taken down by the Guardians' EMP blast. With no option left to them but to run, Captain Lasky promised the ''Infinity'' would return when the Created could be fought.<ref name="Guardians">'''Halo 5: Guardians''', ''campaign level [[Guardians]]''</ref> The UNSC ''Infinity'' was one of the few vessels that managed to escape the Guardians.<ref name="Mythos198">'''Halo Mythos''', ''page 198''</ref> At least a day after the Created began to subjugate Earth, ''Infinity'' answered a distress call by the {{UNSCShip|Sentry of El Morro}} which was under attack by the [[Warden Eternal]].<ref name="rossbach's world">'''[[Halo: Fractures]]''', "[[Rossbach's World (story)|Rossbach's World]]", ''page ???''</ref>

When Fireteam Osiris and Blue Team returned to Sanghelios, they learned that Halsey, using the Forerunner technology in the area, had managed to make contact with Roland, who remained loyal to humanity, aboard the ''Infinity''. Due to needing Halsey's help to stop the Created threat, Lasky set up a rendezvous on the far side of [[Suban]] at eighteen hundred standard time the next day where ''Infinity'' would remain for fifteen minutes. Using [[India 127|the Pelican]] the Spartans had escaped from [[Genesis]] on, they were able to reach ''Infinity'' which [[Captain]] [[Veronica Dare]] had also joined up with.{{Ref/Reuse|BB}} Shortly after returning to the ship, [[Edward Buck]] was sent on a classified mission with Dare to reunite [[Alpha-Nine]] in order to contact the [[United Rebel Front]] on [[Cassidy III]] in hopes of gaining information on the Forerunner cloaking technology protecting their colony. Lasky set up a predetermined series of locations and times where ''Infinity'' could be found for brief periods, allowing Alpha-Nine to return to the ship after the mission. Later, while relaxing in the Full Moon bar on ''Infinity'' with Fireteam Osiris and Alpha-Nine, Buck and Dare were married by Roland who stated that as the ship's AI, he had the same authority to perform weddings that the captain of a ship did.<ref>'''[[Halo: Bad Blood]]'''</ref>

===Operation: WOLFE===
{{Main|Operation: WOLFE}}
In October 2559, it deployed a portion of its Spartan and Marine complement into [[New Mohács]] to help the [[Viery Militia]] in warding off the Banished assault.<ref>''[[Halo: Shadows of Reach]]'', Chapter 13 and 16</ref> It soon jumped into slipspace following the completion of Operation WOLFE because it detected a Tau surge indicating the arrival of a Guardian.<ref>''Halo: Shadows of Reach'', Epilogue</ref>

===Conflict at Zeta Halo===
[[File:HINF- Infinity rammed.png|230px|thumb|left|The moment when UNSC ''Infinity'' is rammed by a Banished dreadnought]]
In late 2559, ''Infinity'' was part of a UNSC fleet that was sent to [[Installation 07]] on a mission to eliminate Cortana using [[The Weapon]]. ''Infinity'' arrived at Zeta Halo on December 12 and immediately fell into [[Battle over Installation 07|an ambush]], with the ''Infinity'' sustaining multiple hull breaches from the initial attack.{{Ref/Game|Id=ia4|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #04 - Arrival}} The Banished had arrived at the ring earlier, and begun fortifying the ring's surface to neutralize Cortana.{{Ref/Book|Id=enc22p25|Enc22|Page=25}} Four approaching [[Banished dreadnought]]s attacked the supercarrier and overwhelmed its defenses.{{Ref/Quest|Id=hor|HI|Reckoning|House of Reckoning|Quote=You were there when we struck the ''Infinity''.

Following the evacuation order, ''Infinity'' was rammed amidships by a [[Banished dreadnought]] and sustained severe damage. Shortly afterward, John-117, who had stayed aboard and continued fighting in the hangar, was confronted by Atriox and flung out into space; both he and the Banished leader were presumed killed in action since contact with them was lost. Meanwhile, a [[Battle for Zeta Halo|conflict]] between UNSC survivors and the Banished for control of Zeta Halo unfolded on the ring's surface.{{Ref/Game|HI|trailer|Detail=[[Halo Infinite Campaign Gameplay Premiere|Campaign Gameplay Premiere]]|Id=Premiere}}

''Infinity'' went missing following the battle, and while its status is unknown,{{Ref/Reuse|StatusUnknown}} the surviving UNSC personnel believed it to be destroyed.{{Ref/Level|HINF|[[Warship Gbraakon]]}} [[Escharum]] later claimed that the flagship of the UNSC had been neutralized in only four minutes.{{Ref/Reuse|hor}}{{clear}}

===Hull and propulsion===
From stem to stern, ''Infinity'' has a length of 5,694.2 meters (18,681.6 feet), a beam of 833.3 meters (2,733.9 feet), and a height of 1,041.2 meters (3,415.9 feet).

As of February 2558, ''Infinity'' had an official complement of 17,151. This included 8,900 Navy personnel, 5,400 [[UNSC Marine Corps|Marines]], 750 [[Orbital Drop Shock Troopers|ODSTs]], 1,700 [[ONI]] agents, 480 civilian [[Unified Earth Government|UEG]] personnel, 8 [[Huragok]], and 24 [[Swords of Sanghelios]] members.

Mass deployment is realized through a large number of bays located throughout the vessel. ''Infinity'' has 275 Cat-1 primary bays, 140 Cat-2 secondary bays, 108 Cat-3 matériel deployment bays, and ten Cat-8 sub-vessel deployment bays: the last of these each carries a {{Class|Strident|heavy frigate}} or an {{Class|Anlace|light frigate}}. Single deployment is afforded by 329 [[Single Occupant Exoatmospheric Insertion Vehicle|R1295 Launching System/M9407 SOEIVs]] and 124 B854 Jettison Bays/M8823 HEVs. Emergency escape vehicles include 8,900 [[SKT-29 shuttlecraft|SKT-29 Class-8 Enclosed Heavy Lifeboats/Controlled]] and 12,750 [[RLT-85 Emergency Shuttlepod]]s.{{Ref/Reuse|packet}} 

''Infinity'' is also equipped with sizable recreational areas, including a large atrium-like memorial park. Located under an enormous transparent dome,<ref>'''Halo: The Thursday War''', ''pages 68-69''</ref> the park has a self-contained biosphere complete with plants and animal life and has been said to surpass many natural parks on [[Earth]] in size.<ref>'''Halo 4''', campaign level ''[[Infinity (level)|Infinity]]'' (Marine: ''" "Infinity's memorial park is something else, man.

The Science Deck of the ''Infinity'' is home to state-of-the-art laboratories and research facilities, provided by ONI and the [[Watershed Division]].{{Ref/Reuse|wf infinity}} 

It is unclear whether ''Infinity'' has a permanent escort formation apart from her internally docked sub-vessels, though on occasion she has been accompanied formations comprising as many as dozens of vessels. An escort fleet consisting of roughly two dozen {{Class|Paris|heavy frigate}}s and a dozen {{Class|Autumn|heavy cruiser}}s accompanied ''Infinity'' on her first mission to Requiem, though only two of the frigates are known to have arrived along with their parent ship;<ref>'''Halo 4 Forward Unto Dawn''', ''Part 5''</ref> they may have been destroyed when the shield world's artificial gravity well was activated.{{Ref/Reuse|Commissioning}} Eleven ''Autumn''-class cruisers (including {{UNSCShip|Song of the East}})<ref name="VIS">'''Halo 4: The Essential Visual Guide'''</ref> accompanied ''Infinity'' at some point between her return to Earth (''ca.''

Emplaced throughout the ship are 1,100 missile pods of three types: ''Archer'', ''Rapier'', and ''Howler''. The [[Archer missile#M42 Archer|M42 Archer missile]] provides secondary armament for ''Infinity'' with 350 pods of 24 missiles each. Additional missiles include the [[Rapier missile|M75 Rapier]] (250x30 missiles) and the [[Howler missile|M96 Howler]] (500x20 missiles).

==Production notes==
{{Linkbox|gallery=yes}}
*This ship plays a major role in ''[[Halo 4]]''{{'}}s and ''[[Halo 5: Guardians]]''{{'}}s campaigns and serves as the fictional backdrop for the ''Infinity'' multiplayer component. This component encompasses both ''[[War Games]]'' (the competitive multiplayer mode) and ''[[Spartan Ops]]'', an episodic cooperative campaign. War Games represents the training exercises of the SPARTAN-IV supersoldiers on the warship's holographic training deck. ''Spartan Ops'' puts up to four players in the role of [[Fireteam Crimson]] in a series of weekly episodic campaign missions and cinematics following the ongoing story of the ''Infinity'' and her crew.{{Ref/Reuse|Game Informer 52012}} ''Infinity'' also plays a major role in the ''[[Halo: Initiation]]'' and ''[[Halo: Escalation]]'' comic series.
*In ''Halo 4'' and ''Spartan Ops'', ''Infinity''{{'}}s bow has five apparent MAC gun barrels, despite canonically only having four MACs. This discrepancy is corrected in the ship's ''Halo 5: Guardians'' model, in which the topmost barrel has been removed.
*Although Game Informer has reported that the Infinity had a "devastating destruction crash" on the surface on the ring, the ship was never explicitly mentioned as having crashed on the ring's surface in-game, with Echo 216 unable to locate the supercarrier, casting some doubt on the Infinity's true fate.{{Ref/Site|Id=GIInf|URL=https://www.gameinformer.com/2021/11/11/off-the-golden-path-progression-and-exploration-in-halo-infinite|Site=Game Informer|Name=Off The Golden Path – Progression And Exploration In Halo Infinite|D=11|M=11|Y=2021|Quote=[...] while rallying the UNSC forces that have crash-landed there after the devastating destruction crash of the UNSC Infinity.}}
