The '''NOVA Bomb''' is a [[Human]] very high-yield combination of nine fusion warheads, used by the [[United Nations Space Command]]. 

==Background==
The NOVA Bomb is a cluster of nine fusion warheads encased in lithium triteride. When the warheads are activated the lithium triteride shell focuses the blast in upon itself, multiplying the destructive power a hundredfold. This gives the NOVA Bomb an unprecedented payload for its size. Its capability to destroy a planet, thus causing the nickname "Planet-Killer" to be derived. It should be noted, that on the one recorded event when a NOVA Bomb was detonated in the midst of a fleet close to a planet, it scorched one-quarter of the planet due to a concentration of thermal energy inside the planet's atmosphere and shattered a moon. Any further detailed analysis on the full power of this bomb has yet to be mentioned in the Halo series, but it is known that it has the most destructive capabilities in the UNSC arsenal.

== Theory ==
The NOVA Bomb's explosive power is quickly depleted due to the lack of particles or atmosphere around it when it's detonated in space. This results in a much quicker release of energy, with the possibility of even further multiplying its damage to ships, planets, moons, and other celestial objects due to the lack of energy absorbing particles in space. However if detonated inside a planet's atmosphere, a portion of the total energy generated would be dispersed throughout the atmosphere. The density as well as composition of the atmosphere are the largest contributing factors when determining how much energy is dispersed. Even though the power of the NOVA Bomb is not mentioned in the book, it can be loosely calculated: nine warheads multiplied by thirty megatons (though it is not known if this is the actual yield of one NOVA fission warhead) each and this multiplied again by the 100 fold yield caused by the lithium triteride shell. So the rough estimation for the NOVA Bomb may be around that of a twenty-seven gigaton yield blast(if the multiplier was exactly one hundred-fold the equation is: 9 warheads x 30 megaton x 100 = 27 gigaton yield).

== History ==
It was intended for the NOVA Bomb to be used in space against the [[Covenant]] [[Fleet]] during the [[Battle of Reach]]. In the novel Halo: First Strike it was left on [[Reach]] and "repurposed" by [[Admiral Whitcomb]]. His reasoning was that "Either the Covenant pack those bombs up and take them home for study, a possibility that I hope to God happens. A bomb like that could crack their homeworld in two. Or, the bombs stay here and they'll stop the Covenant on Reach..."<ref>''[[Halo: First Strike]]'', page 180</ref>

The only documented triggering of a NOVA Bomb occurred when it was accidentally detonated by a group of [[Huragok]]. The Huragok, through their curiosity and frenzied obsession, fixed the circuitry of the bomb (which they had taken apart in the first place) while Kwassass (a Grunt assinged to the ship upon which the NOVA was stored) translated the message being brodcast from it. The Huragok then set off the bomb despite [[Kwassass]]'s, attempts to stop them. The Huragok completed the detonation timer's circuit, which promptly resulted in the detonation of the bomb. The resulting explosion occurred between a Covenant outpost planet [[Joyous Exultation]] and its moon, [[Malhiem]], scorching a quarter of the planet and shattering said moon. The resulting winds on Joyous Exultation flattened cities and spawned tidal waves. Every ship within the NOVA Bomb's range (excluding ones on the opposite side of the planet) boiled and vaporized in an instant.<ref>''[[Halo: Ghosts of Onyx]]'', page 244</ref> This was actually extremely unfortunate for the humans, as the [[Sangheili]], led by [[Imperial Admiral]] [[Xytan 'Jar Wattinree]] could have shattered the [[Jiralhanae]] fleet, thus effectively destroying the Covenant. This could have immediately turned the tide of the war for both the UNSC and the [[Covenant Separatists]]. However, the Imperial Commander there, along with all of the station elites still believed in the Original Covenant lies, and would have attacked the humans at Earth, and possibly declare Thel 'Vadam (The Arbiter) and Rtas heretics. The NOVA Bomb explosion severely damaged three-quarters of the fleet that was there, totaling over 300 ships. Eighteen Destroyers, two Cruisers, one Carrier and the Flagship ''[[Incorruptible]]'' escaped the NOVA Bomb explosion due to a [[Slipspace]] jump ''en masse'' just seconds prior to the explosion. Other ships arrived to reinforce the Incorriptible arrived from Joyous Exultation, suggesting that they were behind the planet and thus escaped the NOVAs detonation. The novel describes the explosion as though "a small star erupted between Joyous Exultation and its moon."

==[[Delta Halo]]==
During the [[Battle of Installation 05]], and the subsequent Quarantine of the Installation and ''[[High Charity]]'', [[Cortana]] requested that [[UNSC]] [[HIGHCOM]] deploy a NOVA Bomb around [[Installation 05]] and ''High Charity'' to stop the outbreak of the [[Flood]] in order to destroy the Covenant Holy Capital. 

However, this request was not granted likely due to the low number of nuclear warheads left and their need to protect the [[Inner Colonies]]. ''High Charity'' was not bombed and later landed on [[Installation 00]]. It is also possible that this request was granted, but that High Charity went into [[Slipspace]] before the warhead could even be launched.
However this last possibility is highly unlikely because a nuclear warhead is very easily spotted when transitioning from a Slipspace jump.

== Trivia ==
*The NOVA Bomb was a bomb mentioned in the novel ''Starship Troopers'', wherein it is described as "being able to split a planet in half." It is likely that this inspired the Halo Universe's own NOVA Bomb.  
*A NOVA Bomb, is also the common name for the heavy bomb used in Starfox games. Though not nearly as powerful as the Halo and ''Starship Troopers'' bombs of the same name, the NOVA Bomb is one of the most powerful weapons you can use in the Starfox series. It also appears in the ''Andromeda'' TV series. In that show it is a weapon capable of causing stars to go into the supernova stage, therefore destroying the entire system around it (hence the name).
*Only a handful of these enormously powerful weapons have ever been made in the history of the UNSC. 
*The NOVA Bomb was frequently referenced in [[Halo: Ghosts of Onyx]].
*While it was first used in ''[[Halo: Ghosts of Onyx]]'', it was first mentioned in an earlier novel ''[[Halo: First Strike]]''.
