{{Quote|A little slice of Armageddon.|[[William-043|Will-043]], describing FENRIS nuclear warheads}}<ref name="HaloGhostsOnyxCh24">'''[[Halo: Ghosts of Onyx]]''', "chapter 24"</ref>
The '''FENRIS nuclear warhead''' is a type of [[United Nations Space Command|UNSC]] [[nuclear weapon]] and part of the [[Medium Fusion Destructive Device]] class.<ref name="H4VG">'''[[Halo 4: The Essential Visual Guide]]''', ''page 83''</ref>

==Description==
FENRIS warheads had superhardened cases to contain the detonation longer and boost the thermonuclear yield.<ref name="HaloGhostsOnyxCh1">'''[[Halo: Ghosts of Onyx]]''', "chapter 1"</ref> The hardened cases also made them resilient to small arms and explosions, so resilient in fact that they were regarded as useless without the detonation codes. FENRIS warheads are considered low-yield devices.<ref name="HaloGhostsOnyxCh23">'''[[Halo: Ghosts of Onyx]]''', "chapter 23"</ref>

They may be detonated by remote{{Ref/Reuse|HaloGhostsOnyxCh23}} or by pressing the warhead's detonator manually.<ref name="HaloGhostsOnyxCh39">'''[[Halo: Ghosts of Onyx]]''', "chapter 39"</ref>

==History==
In [[2531]], the [[Insurrectionist]]s possessed three FENRIS warheads at [[Camp New Hope]] on [[Victoria]]. The weapons were recovered during [[Operation: SMOKING ACES]] by [[SPARTAN-II Program|SPARTAN-II]] [[Blue Team]].{{Ref/Reuse|HaloGhostsOnyxCh1}}

By [[2552]], the FENRIS was slated for decommissioning. However as the [[Human-Covenant War]] made a turn for the worse and the UNSC's nuclear stockpile dwindled, they were returned to service.{{Ref/Reuse|HaloGhostsOnyxCh23}}

During the [[Battle for Earth]], [[SPARTAN-II Program|SPARTAN-II]] [[Blue Team]] recaptured 12 FENRIS warheads from the [[Covenant]] at the [[Centennial Orbital Elevator]]. At the top of the elevator, six armed warheads were smuggled aboard a [[Covenant destroyer]] while another destroyer, ''[[Bloodied Spirit]]'' was commandeered by Blue Team. The enemy destroyer was destroyed by a combination of internal nuclear detonations and [[plasma turret|plasma torpedo]] fire. Blue Team then made the [[Slipstream space|slipspace]] jump to [[Onyx]].{{Ref/Reuse|HaloGhostsOnyxCh23}}

As the [[Onyx Conflict]] drew to a close, [[Kurt-051]] manually detonated 2 cut-down FENRIS warheads to deny the [[Joyous Exultation Covenant|Covenant]] access to Onyx's internal [[Dyson sphere|Micro Dyson sphere]].{{Ref/Reuse|HaloGhostsOnyxCh39}}

==Trivia==
[[wikipedia:Fenrir|Fenrir]] is a monstrous wolf in Norse mythology.
