Editing Self-destruct

{{Status|Canon}}

The '''self-destruct''' is 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-destruct mechanisms are also employed by the [[Covenant]] and [[Banished]] in their [[Covenant citadel|citadels]] and [[Banished outpost]]s.

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>'''Halo Evolutions''', ''Midnight in the Heart of Midlothian''</ref>

While originally sent to 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 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>'''[[Halo 5: Guardians]]''', campaign level ''[[Blue Team (level)|Blue Team]]''</ref>

 

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>'''[[Halo: Silent Storm]]''', ''Chapter 15''</ref>

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/Reuse|Oblivion}}

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>'''[[Halo: Outpost Discovery]]''', ''[[Covenant Escape]]''</ref>
