The '''self-destruct''', also referred to as a '''scuttling''' sometimes in ships, is the explosive self-destruction of an object or vessel.
==Overview==
In the [[UNSC]], the self-destruct is often an integrated mechanism present in starships and [[United Nations Space Command|UNSC]] [[military base]]s and is used to cause a massive explosion to completely destroy itself in order to prevent vital navigational data and strategically-valuable information from falling into enemy [[Covenant]] clutches, as per paragraph five of the [[Cole Protocol]]. Self-destructs can take the form of reactor overloads or, alternatively, an explosive device to be detonated, usually an [[octanitrocubane]] charge or a [[nuclear weapon]].

According to rumors, ONI installations would self-destruct if they couldn't confirm that the installation's authorized keeper was still alive.{{Ref/Reuse|env15}}

Self-destruct mechanisms are also employed by the [[Covenant]] and [[Covenant remnants|their remnants]] in their ships, [[Covenant citadel|citadels]] and [[Banished outpost|outposts]]. The Covenant were known to use a self-destruct to keep themselves from being captured in the event of a boarding action{{Ref/Reuse|ss3}}{{Ref/Reuse|ET6}} or as a method to get rid of boarders.{{Ref/Reuse|package}}{{Ref/Novel|Id=TCP22|TCP|Chapter=22}}

[[Forerunner]] installations employ self-destruct mechanisms as well. In the case of [[Requiem]], the [[shield world]]'s self-destruct resulted in the [[Epoloch system]]'s star going [[supernova]] as well.{{Ref/Reuse|Exodus}} In the case of [[Installation 07|Gyre 11]], the ring was programmed to enter a course e which would result in a collision with [[Wolf-faced planet|a planet]] in several days.{{Ref/Novel|Id=pri279|Pri|Page=279}}

While more informal, boarding parties have occasionally triggered a vessel to self-destruct by rigging a reactor overload or causing the engines to overheat such as ''[[Argent Moon]]''{{Ref/Reuse|Blue Team}} and ''[[Ghost of Gbraakon]]''.{{Ref/Reuse|Warship Gbraakon}}

==Examples==
===Banished===
====''Ghost of Gbraakon''====
After Pelican ''[[Echo 216]]'' was captured by the Banished warship ''[[Ghost of Gbraakon]]'', with [[Fernando Esparza]] and John-117 on it, the Master Chief scuttled the [[Banished dreadnought]] by destroying both [[cooling manifold]]s on the ship's bridge and then overheating the engines.{{Ref/Quest|Id=Warship Gbraakon|HI|Ringfall|Warship Gbraakon}}

===Covenant===
====''Radiant Arrow''====
During the [[Skirmish over Netherop]], the [[Shipmaster]] of the [[Covenant frigate]] ''[[Radiant Arrow]]'' activated the ship's self-destruct after it was boarded by [[SPARTAN-II]] [[Blue Team|Blue]], [[Green Team|Green]] and [[Gold Team]]s. The Shipmaster depressed a dead man's switch in order to give his crew time to abandon ship before detonating it. As the rest of the Spartans fled the ship, [[John-117]] attempted to stop as many of the crew from escaping as possible. With his last breath, the Shipmaster released the dead man's switch, causing the ''Radiant Arrow'' to explode. However, John was able to escape using one of the ship's [[Covenant escape pod|escape pods]] and only the ''Radiant Arrow's'' crew died in the explosion.{{Ref/Novel|Id=ss3|SS|Chapter=3}}

====''Retribution's Thunder''====
After discovering [[the Rubble]], the [[Covenant destroyer]] ''[[Retribution's Thunder]]'' was betrayed and attacked by the [[Kig-Yar]] vessel ''[[A Psalm Every Day]]'' who wanted to take credit for the discovery themselves. With the ship disabled, [[Shipmaster]] [[Thel 'Vadam]]ee ordered the self-destruct activated, killing the boarders.{{Ref/Reuse|TCP22}} However, Thel and most of his bridge crew survived and were captured and taken to the Rubble.{{Ref/Novel|TCP|Chapter=24}}

====''Resplendent Fervor''====
After the {{Class|CAS|assault carrier}} ''[[Resplendent Fervor]]'' was cut in two during [[Operation: WARM BLANKET]], the discarded rear half was set to self-destruct in an attempt to kill the Spartans attempting to rescue Dr. [[Catherine Halsey]]. However, the Spartans and Halsey successfully managed to escape from the explosion.{{Ref/Film|Id=package|HLeg|Story=[[The Package (animated short)|The Package]]}}

====''Pious Inquisitor''====
During the [[Skirmish on Pious Inquisitor]], with the humans having killed several of [[Chol Von]]'s crew and bearing down on the bridge, Von ordered [[Ril]] to detonate the ship's [[plasma turret|plasma torpedo]] reserves, choosing to destroy ''[[Pious Inquisitor]]'' over leaving it to the humans. As Chol and her team attempted to leave the bridge, the [[Spartan-II]], [[Naomi-010]], entered the bridge and killed Noit. Von and Bakz were able to flee from the Spartan. She and her remaining crew then made their way to a shuttle bay in order to escape. [[Kilo-Five]] was able to escape in their dropships before the explosion while [[Staffan Sentzke]] and [[Sometimes Sinks]] escaped in a Spirit that Sinks had earlier outfitted with a miniature [[slipspace drive]].{{Ref/Novel|Id=mordi|MorDi|Chapter=14}}

====''Vigilance with Piety''====
When a team from the ''[[Shadow of Intent]]'' boarded his ship, the ''[[Vigilance with Piety]]'', [[Kafo Dein]] activated the storm cutter's self-destruct and fled in a [[Ren]]. Dein also did this without evacuating his crew, willing to leave them to die in the ship's destruction. The crew abandoned ship in the storm cutter's docked craft, including its Seraphs and Banshees and overloaded the ''Piety''{{'}}s limited supply of Phantoms in their desperation. The [[Swords of Sanghelios]] team stole [[war sphinx]]es salvaged by Dein to escape from the explosion as there were no other craft left.{{Ref/Novel|Id=ET6|ET|Chapter=6}}

===Forerunner===
====The Knowing====
During [[Operation: FIRESIDE]], the [[Forerunner]] construct called [[the Knowing]] self-destructed on the orders of [[Taylor Miles|Dutch]] and [[Kojo Agu|Romeo]] as [[Reclaimer]]s in order to keep the construct out of [[Covenant]] hands.{{Ref/Comic|HHj|Issue=5}}

====Requiem====
After getting half of the [[Janus Key]], [[Jul 'Mdama]] activated a [[Flood]] [[containment protocol]]{{Ref/Site|Id=CatalogContainment|URL=https://forums.halowaypoint.com/yaf_postsm2994218_Catalog-Interaction.aspx#post2994218|Site=Halo Waypoint|Page=Catalog Interaction (post 2994218)}} on [[Requiem]] that effectively acted as the planet's self-destruct. As a result, Requiem was set on a course into the [[Epoloch system]]'s star. [[Jul 'Mdama's Covenant|Jul's forces]] fled the planet, but the {{UNSCShip|Infinity}} was stuck because of the [[interdiction web]] anchoring the ship to Requiem. After [[Requiem slipspace artifacts|the three artifacts]] creating the anchor were deactivated, the ''Infinity'' escaped at the last minute. Requiem fell into the star which went [[supernova]] moments later.{{Ref/SpOps|Id=Exodus|Exodus (Spartan Ops)|EpisodeLinkText=Exodus}}

===Human===
====UNSC ''Prophecy''====
Severely damaged during the [[Harvest campaign]], the {{UNSCShip|Prophecy}} was boarded by teams from the {{UNSCShip|Spirit of Fire}} to purge its navigation database as per the [[Cole Protocol]]. After Sergeant [[John Forge]] succeeded in purging the navigation database, the ship's self-destruct was initiated by its [[AI]] [[FitzGibbon]] to keep the ship out of [[Covenant]] hands.{{Ref/Comic|HWG}}

====UNSC ''Starry Night''====
After being shot down during the [[Battle of Seoba]], the [[Prowler]] {{UNSCShip|Starry Night}} had its self-destruct, a one-megaton [[Fury tactical nuclear weapon]] in the engineering compartment, activated by [[Linda-058]]. The self-destruct took out the ''Starry Night'' and the [[Covenant]] [[intrusion corvette]] that tried to capture it.{{Ref/Novel|SS|Chapter=15}}

====UNSC ''Night Watch''====
During an insertion to [[Netherop]] during the [[Battle of Netherop]], the {{Class|Razor|prowler}} {{UNSCShip|Night Watch}} was shot down by forces from the [[Flotilla of Unsung Piety]]. In order to keep the Prowler and its technology out of enemy hands, [[Lieutenant Commander]] [[Amalea Petrov]] armed the ship's self-destruct, a [[Fury tactical nuclear weapon]] and set it to be remote-detonated. The ship's crew worked to get as far away as possible before the detonation, with [[Frederic-104]] clearing a culvert of the danger of avalanches burying the survivors taking cover there. As the Covenant began launching their aircraft from the crash site, Petrov activated the self-destruct and ensured that no Covenant who had been aboard the vessel got out alive to report on what they found. However, while the Prowler crew was safe, two of the [[Castoffs]] who had gotten too close to the blast site were killed.{{Ref/Novel|Oblv|Chapter=8}}

====UNSC ''Phyllis Wheatley''====
During the [[Battle of Netherop (2526)|Battle of Netherop]], with no chance of getting off [[Netherop]] in the {{UNSCShip|Phyllis Wheatley}}, the salvage ship's self-destruct was activated once all of the survivors had been lifted clear by Pelicans.{{Ref/Novel|Oblv|Chapter=21}}

====HRUNTING/YGGDRASIL Mark I ADS====
During the [[Algolis Invasion]], the [[HRUNTING/YGGDRASIL Mark I ADS|prototype exoskeleton]] was ordered destroyed under the [[United Nations Space Command Emergency Priority Order 098831A-1|Cole Protocol]]. Despite this order, the Marine known as [[Ghost (Marine)|Ghost]] took control of the exoskeleton to use it to buy escaping Marines and civilians time to escape for the duration of the self-destruct sequence. The exoskeleton took heavy damage, but Ghost completed his mission. Once the timer ran out, Ghost activated the self-destruct, obliterating all of the nearby Covenant forces in a nuclear explosion.{{Ref/Film|HLeg|Story=[[Prototype]]}}

====UNSC ''The Heart of Midlothian''====
When the [[UNSC destroyer|destroyer]] {{UNSCShip|The Heart of Midlothian}} was captured and [[Naval boarding|boarded]] by the Covenant, the ship's [[AI]], [[Mo Ye]], told Sergeant [[Michael Baird]] to go to the bridge to reconnect Mo Ye to the rest of herself and the ship in order to enable the self-destruct and destroy the ship along with its data and all the Covenant aboard. ''The Heart of Midlothian's'' self-destruct occurred by shaped nuclear charges detonating inward and igniting the fissionable material in the ship's reactor, causing a greater explosion that destroyed the surrounding Covenant ships.{{Ref/Anthology|Evo|[[Midnight in the Heart of Midlothian]]}}

====''Fermion''====
[[File:FoR - Fermion self-destruct.png|thumb|200px|''Fermion'' self-destructs as several Covenant ships pass nearby.]]
The UNSC [[Remote Scanning Outpost]] ''[[Fermion]]'' was forced to enact paragraph five of the Cole Protocol and had to flood the station's reactors with deuterium, causing a critical overload in order to destroy the station's science library, which was offline for repairs.{{Ref/Novel|Id=pretty|FoR|Page=282 (2001 edition)}}{{Ref/Novel|FoR|Page=286 (2001 edition)}}

====MJOLNIR Powered Assault Armor====
[[MJOLNIR Powered Assault Armor]] possessed a self-destruct called the [[fail-safe detonation system]]. If a [[SPARTAN programs|Spartan]] was killed or wounded fatally, or they were forced to shed the armor in the field, the self-destruct protocol had to be enacted by either themselves or a nearby Spartan. This was done to avoid capture of the suit and/or the wearer for identification or technological study.{{Ref/Novel|Id=FS34|FS|Chapter=34}} Despite its original purpose, Spartans historically viewed the fail-safe detonation's activation as a final act of reprisal, eliminating their enemies even if they themselves wouldn't survive the encounter.{{Ref/Novel|ET|Chapter=5}}

[[John-117]] engaged the system on [[Grace-093]]'s armor following her death in [[Operation: FIRST STRIKE]].{{Ref/Reuse|FS34}}

[[Frederic-104]]'s damaged and inert [[CENTURION-class Mjolnir]] suit's fail-safe detonation system was activated at the conclusion of [[Operation: JOVIAN WHISTLE]] on [[Gao]] in order to prevent the armor from falling into enemy hands, destroying two low-flying Gao [[MV-29 Wyvern]]s in the process.{{Ref/Novel|LL|Chapter=27}}

During the [[Battle of Boundary]], the mortally wounded [[James Solomon]] activated his armor's self-destruct, sacrificing himself to protect [[Chloe Hall]] with the blast wiping out the [[Banished]] forces closing in on him, including several [[Qavardu Workshop Gravemaker|Gravemakers]].{{Ref/Novel|ET|Chapter=37}}

====UNSC ''Pillar of Autumn''====
Towards the end of the [[Battle of Installation 04]], [[Cortana]] and Spartan [[John-117]] were forced to activate the {{UNSCShip|Pillar of Autumn}}'s self-destruct sequence in an effort to prevent the [[Flood]] parasite from getting off of [[Installation 04]], and particularly keeping [[343 Guilty Spark]] from firing the [[Halo Array|Halo]] and wiping out all sentient life within a radius of 25,000 lightyears. Cortana and Master Chief's plan would have successfully worked had not Guilty Spark aborted the self-destruct sequence, and as Cortana was unable to reactivate the countdown, so the Chief proposed using explosives to cause the [[fusion drive|fusion reactors]] to go critical and explode, thereby destroying the ring.{{Ref/Level|CE|The Maw}}

====UNSC ''Silent Claw''====
The {{UNSCShip|Silent Claw}} took heavy fire during its run on [[Salvation Base]] and the Spartans were forced to bail from the craft before it crashed violently into the ground. [[Fred-104]] instructed [[Damon]] to send the signal that would trigger what remained of the ship to self-destruct.{{Ref/Novel|Id=R15|Ret|Chapter=15}}

====UNSC ''Promise of Dawn''====
In order to save his people, Dr. [[Chen Bax]] decided to sacrifice himself to use the {{UNSCShip|Promise of Dawn}}'s self-destruct to set off an avalanche that would wipe out most of the [[Jul 'Mdama's Covenant|Covenant's]] ground troops. After [[Linda-058]] was away and he had told his followers where to find the nav unit for their ship, Chen set off the self-destruct with a remote, creating the avalanche and saving his people at the cost of his own life.{{Ref/Comic|Id=HLW4|HLW|Issue=4}}

====Gila Station====
When [[Gila Station]] was invaded by [[Shipmaster]] [[Thars 'Sarov]] and his forces, shortly after the departure of [[Rojka 'Kasaan]] and his surviving forces with [[Melody Azikiwe]], the base self-destructed. Melody surmised that it was [[Commander]] [[Greg van Eekhout]]'s last gift and recalled rumors that she'd heard about ONI installations that would self-destruct if they couldn't confirm that the station's authorized keeper was still alive. Melody wondered if she had been playing for time with Thars inside of a ticking time bomb while Rojka expressed confidence that Thars had survived the explosion.{{Ref/Novel|Id=env15|Env|15}}

====''Pilgrims' Pride''====
In [[2558|March 2558]], the {{UNSCShip|Infinity}} found the damaged [[freighter]], ''[[Pilgrims' Pride]]'', leaking atomic matter with faint life signs aboard. ''Infinity'' tugged the ship into one of its deployment bays. An ambush was sprung within the bay when the freighter set itself to self-destruct and multiple UNSC aircraft exited its cargo bay. [[Fireteam Majestic]] was deployed along with Fireteams [[Fireteam Colossus|Colossus]] and [[Fireteam Fenrir|Fenrir]] to repel the attack and prevent the freighter from self-destructing inside the ''Infinity''. The ship was ejected from the ''Infinity'' and exploded in space some distance away.{{Ref/Comic|HE|Issue=4}}

====''Argent Moon''====
While originally sent to [[Operation: BIRD IN HAND|reclaim]] the ONI space station ''[[Argent Moon]]'', after a [[Jul 'Mdama's Covenant|Covenant]] [[fleet]] showed up, Blue Team decided to scuttle the station instead by overloading the reactor in order to keep ''Argent Moon'' out of Covenant hands. However, although [[John-117]] started the overload, a containment protocol was initiated to cool the reactor and prevent it from melting down. Blue Team followed the reactor to an outside area where coolant would be pumped to the reactor to prevent the meltdown. Blue Team exposed the coolant pipes and then destroyed them with [[D'nomlhe-pattern Banshee|Banshees]], fighting off Covenant interference. With the cooling system destroyed, the reactor melted down unimpeded. Blue Team escaped in the [[ONI Acrisius|ONI ''Acrisius'']], a {{Class|Winter|prowler}} in ''Argent Moon's'' docking bay while the explosion destroyed all nearby Covenant ships.{{Ref/Level|Id=Blue Team|H5|[[Blue Team (level)|Blue Team]]}} The [[Forerunner]] [[archeon-class ancilla]] [[Intrepid Eye]] was also believed to have been destroyed in the reactor overload.{{Ref/Novel|Id=DW6|DW|Chapter=6}} However, Intrepid Eye barely managed to escape by attaching herself to the ''Acrisius'' as Blue Team used the Prowler to escape.{{Ref/Novel|Id=DW5|DW|Chapter=5}}

====UNSC ''Special Delivery''====
After the {{UNSCShip|Special Delivery}} was shot down on [[Reach]] during [[Operation: WOLFE]], its [[octanitrocubane]] self-destruct charge was triggered by [[Major (UNICOM)|Major]] [[Eznik Van Houte]], using the vocal trigger command "''Execute''".{{Ref/Novel|HSoR|Chapter=2}}

====Laconia Station====
On [[Cortana]]'s orders, [[Leonidas]] caused [[Laconia Station]] to self-destruct, killing the 76 [[SPARTAN-IV program|SPARTAN-IVs]] training there.{{Ref/Quest|Hi|Reformation|[[Repository (Halo Infinite level)|Repository]]}}

==Failed attempts==
===UNSC ''In Amber Clad''===
Cortana attempted to blow the engines of the {{UNSCShip|In Amber Clad}} in an effort to stop the Flood and to keep the Covenant from firing [[Installation 05]], but was kept from doing so when the [[Gravemind]] captured her.{{Ref/Level|H2|[[High Charity (level)|High Charity]]}}

===''Infinite Succor''===
During the [[Skirmish on Infinite Succor]], [[Special Operations Commander]] [[Rtas 'Vadum]]ee attempted to activate the ship's self-destruct due to the vessel being overrun by the [[Flood]]. However, the [[Minister of Etiology]] disabled all of the ''[[Infinite Succor]]'s'' primary systems to keep the Flood from accessing them. Instead, Rtas was ultimately forced to plot a [[slipspace]] jump into the [[Soell system]]'s local star in order to destroy the ''Infinite Succor''.{{Ref/Comic|HGN|The Last Voyage of the Infinite Succor}}

===Sundered Legion Prowler===
After detecting the presence of [[Spartan-III]] [[Owen-B096]] in the cockpit, the [[Sundered Legion Prowler]] activated its self-destruct with a ten second countdown. However, when [[Dorian Nguyen]] accidentally hit the cockpit with his hand while trying to get out, the Prowler identified him as his presumed great-grandfather [[Quinn Butain]] based off of Dorian's DNA and allowed Dorian to override the self-destruct.{{Ref/Novel|BatB|Page=187-188}}

===''Supplication of Purity''===
During the [[Battle for Tribute]] in [[2552]], the {{Pattern|Ceudar|heavy corvette}} ''[[Supplication of Purity]]'' was destroyed and crashed into [[Tribute]]. The ship was able to survive the crash mostly intact, and several key components were later salvaged by the [[Office of Naval Intelligence]]. These components were later swept for dangerous material and assigned for display at [[Outpost Discovery]]. However, ONI were not thorough in their check, and a Covenant [[AI]] was able to hide inside a section of the ship containing a maintenance deck. The AI was suppressed by [[Gabriela]], though it was able to initiate the corvette's self-destruct. However, the self-destruct was disabled before it could vaporize the event.{{Ref/Film|Halo: Outpost Discovery|Story=Covenant Escape}}

Instead, they began to gather humans in a last-ditch effort to use them to manually steer the ring away from its destructive course.
-The humans on the ring were taken to the facility where Mendicant Bias' core was housed. There, humans from Earth were separated from the Tudejsa, and their ancestral personality imprints were removed by Mendicant Bias and the Primordial. They were given a choice to cooperate with Mendicant Bias and have their revenge against the Forerunners for [[Human-Forerunner wars|destroying their civilization]] ten thousand years earlier; however, they would first have to help save the Halo from colliding with the approaching planet. Those who accepted Bias' offer were sent to various control stations spread out across the Halo, including the [[Cartographer]].{{Ref/Reuse|p320}} However, humans alone did not possess the knowledge necessary to properly interface with the ring; instead, Flood-infected Forerunners processed by the [[Composer]] were brought in and connected with each human to the Halo's control systems.{{Ref/Novel|Pri|Page=328}} As Installation 07 approached the planet, the controllers successfully managed to reorient the ring in a way the planet would pass through the center; this way, the ring would take heavy damage but had a chance of surviving. Even with this guidance, the ring suffered catastrophic damage.
-While the installation had already begun its passage, a fleet led by the [[IsoDidact]] appeared, and the Didact used his control codes to shut Mendicant Bias down. He immediately entered the Cartographer and connected to the installation's controls with [[Chakas]], while dreadnoughts from the Didact's fleet moved to provide power via connections across the ring. Despite the additional power supply, the Halo could not be saved in its entirety. In order to relieve the tidal stresses exerted on the Halo, the Didact ordered that the installation be reduced by discarding the most damaged plates.
