The ship's massive building expenditures, however, prevented ONI from keeping the ''Infinity'' a complete secret. Many senior members of the Admiralty, such as [[Rear Admiral]] [[Saeed Shafiq]] of [[UNSC Procurement]], were fully aware of the ship's existence at the time of her construction.{{Ref/Novel|Id=Gla16|Gla|Chapter=16}} 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|Gla17}} 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/Novel|Id=TTW2|TTW|Chapter=2}} As of [[2553|March 2553]], technology discovered on [[Trevelyan]], a [[shield world]] located in the [[Zeta Doradus system]], was planned to be incorporated into the ship.{{Ref/Reuse|Gla16}} [[Huragok]] assistance in refining the ship's [[Slipstream space|slipspace]] navigation capabilities, in particular, was expected to push the final construction milestones far ahead of schedule.{{Ref/Reuse|TTW2}} Unlike older warships which had only areas such as a gym or hangar space for [[UNSC Marine Corps|Marines]] and Spartans to train in, ''Infinity'' is the first known vessel to include a state-of-the-art virtual reality combat deck capable of replicating environments from across the galaxy,{{Ref/Reuse|Game Informer 52012}} real or hypothetical, using a combination of [[holography]], props, and simulated sensory input fed through a [[neural interface]].{{Ref/Site|Id=CFBeta|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-beta-late-than-never|Site=Halo Waypoint|Page=Canon Fodder - Beta Late Than Never|D=23|M=12|Y=2019}} ===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/Comic|Id=HI2|HInit|Issue=2}} 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/Comic|HInit|Issue=3}} Additional Spartans were included in the ship's contingent as time progressed{{Ref/Reuse|Gla16}}<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/Reuse|TTW2}}}} 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. 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. Parangosky met with Del Rio and Lasky, who discussed the current refit shape of ''Infinity''.{{Ref/Reuse|TTW2}} 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/Novel|TTW|Page=235}} 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/Novel|TTW|Page=265}} Soon, the [[Sangheili]] opposition ship ''[[Defender of Faith]]'' began to assault Vadam; the Elite vessel was easily destroyed.{{Ref/Novel|TTW|Page=303}} 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/Novel|TTW|Page=361}} ===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/Level|Id=level|H4|H4:Infinity|Infinity}} 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/Level|Id=Reclaimer|H4|H4:Reclaimer|Reclaimer}} 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 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/Level|Id=Shutdown|H4|H4:Shutdown|Shutdown}} ===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/Level|Id=Midnight|H4|H4:Midnight|Midnight}} In the meantime, the Didact acquired the Composer from ''[[Ivanoff Station]]'' near Installation 03 and integrated it into ''Mantle's Approach''.{{Ref/Level|H4|H4:Composer|Composer}} 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/Level|H4|H4:Epilogue|Epilogue}} ===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/SpOps|Artifact (Spartan Ops)|EpisodeLinkText=Artifact}} 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/SpOps|Id=catherine|Catherine}} {{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/SpOps|Id=Invasion|Invasion (Spartan Ops)|EpisodeLinkText=Invasion}} 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/SpOps|Id=Expendable|Expendable}} 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/SpOps|Id=Exodus (Spartan Ops)|EpisodeLinkText=Exodus}} ===Peace talks=== {{Main|Battle of Ealen IV}} In March 3, Fleet Admiral Terrence Hood pulled the ''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/Comic|Id=HE1|HE|Issue=1}} [[Commander (UNSC)|Commander]] [[Bradley]] had taken Lasky's former place as executive officer by this time.{{Ref/Comic|Id=HE2|HE|Issue=2}} 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
