The '''NOVA bomb''' is a [[nuclear weapon|nuclear explosive device]] used by the [[United Nations Space Command]]. Described as "planet killers", NOVAs contain a very high-yield combination of nine nuclear fusion warheads, the explosive power of which is harnessed to compress additional [[Lithium triteride|lithium triteride]] fusionable material to astronomical densities and magnify the overall blast to titanic proportions.{{Ref/Novel|Id=FS19|FS|Chapter=19}} It is quite possibly the most destructive weapon utilized by either side in the [[Human-Covenant War]].

==Background==
==Background==
The NOVA Bomb is a cluster of nine nuclear warheads encased in [[Wikipedia:lithium|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 has earned it the nickname "Planet-Killer". 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's surface due to a concentration of thermal energy inside the planet's atmosphere; it also 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 is the most destructive weapon in the UNSC's arsenal.
The NOVA bomb is a cluster of nine nuclear fusion warheads, each encased in [[Wikipedia:lithium|lithium]] triteride armor. The casing serves as additional fusionable material to the initial nine warheads. When the nine fusion warheads are detonated, the lithium triteride casings are forced together in the center of the combined blast and subjected to massive levels of pressure and superheating,{{Ref/Reuse|FS19}} achieving "neutron star density" according to Vice Admiral [[Danforth Whitcomb]]. It is because of the energy released by the nuclear fusion of the additional material that the resulting detonation's yield is magnified a hundredfold over that of the nine warheads alone.{{Ref/Novel|Id=GoO27|GoO|Chapter=27}} The NOVA bomb carries an unprecedented payload for its size; the bombs are considered "planet killers" due to their destructive potential.{{Ref/Reuse|FS19}}
 
== 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, a low end can be calculated:


Assumptions: the moon is 2km, and the NOVA bomb is only 5,000 km away. 
Originally intended for use against the Covenant in space,{{Ref/Reuse|FS19}} the NOVA bomb has been used in two known engagements: in orbit over the planet Joyous Exultation,{{Ref/Reuse|GoO27}} and on the surface of the planet [[Glyke]].{{Ref/Novel|Id=Env|Env}} In both cases, the effects were extreme. When the bomb was detonated above Joyous Exultation, it heated the planet's atmosphere, scorched one quarter of its surface and shattered a [[Malhiem|nearby moon]].{{Ref/Reuse|GoO27}} When detonated directly on a planet's surface—as was the case on Glyke—the explosion's power was enough to disrupt the planet's structure and overcome the binding energy of its gravity, turning it into a vast cloud of debris and killing every living thing in, on, and around the planet almost instantly.{{Ref/Reuse|Env}}


Calc: Apply the Inverse Squared Law: Source Energy / (4 * Pi * R^2) the radius is the distance from the source to the range.

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]] stationed on the Covenant ''[[Sublime Transcendence]]''. Immediately after [[Kwassass]], a fellow crew member, deciphered Admiral Whitcomb's message, the Huragok, through their curiosity and frenzied obsession, fixed the circuitry of the bomb, detonating it despite [[Kwassass]]'s attempts to stop them. The Huragok completed the detonation timer's circuit, which promptly resulted in its activation. The resulting explosion occurred between a Covenant outpost planet [[Joyous Exultation]] and its moon, [[Malhiem]], scorching half of the planet and shattering the moon. The resulting winds on Joyous Exultation flattened cities and spawned tidal waves. Radiation flooded the planet and killed everything, penetrating the surface of the planet to its core. Every ship within the NOVA Bomb's range, save for those on the opposite side of the planet boiled and vaporized in an instant. It is unknown what the Covenant did with the planet, but it is unable to support life any more.<ref>''[[Halo: Ghosts of Onyx]]'', page 244</ref>

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 ''Incorruptible'' arrived from Joyous Exultation, suggesting that they escaped the bomb's detonation as a result of being positioned on the opposite side of the planet.

Exactly what effect this had on later events is unknown. If the&nbsp;NOVA hadn't detonated and&nbsp;the fleet had survived, the Elites would certainly have had a larger attack force, and been better able to crush the Brute defences during the Battle of Installation 00. However, the crippling of the Elite forces by the Brutes during the Schism&nbsp;was one of the reasons why the Elites [[Covenant Separatists|allied with]] humanity, seeing them as the only viable allies. In addition, Imperial Admiral [[Xytan 'Jar Wattinree|'Wattinree]] seems to have shown no reconsideration of the humans status as heretics,&nbsp;even after rejecting the Prophets, sending a fleet to [[Onyx]] to claim it for the Elites - if he had survived, especially given the amount of reverence given to someone of his stature, it is unknown whether he would have allied with the Arbiter and humanity.

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.

Vice Admiral Danforth Whitcomb's recording on the NOVA bomb, right before it is activated in the space adjacent to the planet Joyous Exultation.

The NOVA bomb is a nuclear explosive device used by the United Nations Space Command. Described as "planet killers", NOVAs contain a very high-yield combination of nine nuclear fusion warheads, the explosive power of which is harnessed to compress additional lithium triteride fusionable material to astronomical densities and magnify the overall blast to titanic proportions.[1] It is quite possibly the most destructive weapon utilized by either side in the Human-Covenant War.

Background[edit]

The NOVA bomb is a cluster of nine nuclear fusion warheads, each encased in lithium triteride armor. The casing serves as additional fusionable material to the initial nine warheads. When the nine fusion warheads are detonated, the lithium triteride casings are forced together in the center of the combined blast and subjected to massive levels of pressure and superheating,[1] achieving "neutron star density" according to Vice Admiral Danforth Whitcomb. It is because of the energy released by the nuclear fusion of the additional material that the resulting detonation's yield is magnified a hundredfold over that of the nine warheads alone.[2] The NOVA bomb carries an unprecedented payload for its size; the bombs are considered "planet killers" due to their destructive potential.[1]

Originally intended for use against the Covenant in space,[1] the NOVA bomb has been used in two known engagements: in orbit over the planet Joyous Exultation,[2] and on the surface of the planet Glyke.[3] In both cases, the effects were extreme. When the bomb was detonated above Joyous Exultation, it heated the planet's atmosphere, scorched one quarter of its surface and shattered a nearby moon.[2] When detonated directly on a planet's surface—as was the case on Glyke—the explosion's power was enough to disrupt the planet's structure and overcome the binding energy of its gravity, turning it into a vast cloud of debris and killing every living thing in, on, and around the planet almost instantly.[3]

Any further detailed analysis on the full power of this bomb has yet to be mentioned, but it is known that it is the most destructive weapon in the UNSC's arsenal.

History[edit]

It was intended for the NOVA bomb to be used in space against the Covenant fleet during the Fall of Reach. The remaining NOVA bombs were left on Reach and "re-purposed" 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..."[1]

The first documented triggering of a NOVA bomb occurred when it was accidentally detonated by a group of Huragok stationed on the Covenant supercarrier Sublime Transcendence. Immediately after Kwassass, a fellow crew member, deciphered Admiral Whitcomb's message, the Huragok, through their curiosity and frenzied obsession, fixed the circuitry of the bomb, detonating it despite Kwassass's attempts to stop them. The Huragok completed the detonation timer's circuit, which promptly resulted in its activation. The resulting explosion occurred between a Covenant outpost planet Joyous Exultation and its moon, Malhiem, scorching half of the planet and shattering the moon. The resulting winds on Joyous Exultation flattened cities and spawned tidal waves. Radiation flooded the planet and killed everything living on it, penetrating the surface of the planet to its core. Every ship within the NOVA bomb's range, save for those on the opposite side of the planet, boiled and vaporized in an instant. The explosion was described as though "a star ignited between Joyous Exultation and its moon."[2]

The NOVA bomb explosion completely destroyed three-fifths 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 moments prior to the explosion.[2] Other ships arrived at Onyx to reinforce the Incorruptible from Joyous Exultation, suggesting that they escaped the bomb's detonation as a result of being positioned on the opposite side of the planet.[4]

During the Battle for Earth, ONI initiated Operation: SUNSPEAR and forwarded a high priority message to the Spartans of Gray Team, declaring "Condition: Endgame" under which they were to execute the detonation of a NOVA bomb on the surface of the Covenant colony world of Glyke, a major military production center home to billions of Sangheili.

  • The NOVA bomb shares its name with a weapon 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 superweapon by the name of "Nova bomb" was also featured in the science fiction series Gene Roddenberry's Andromeda. The 'Nova Bomb' is also the name of a super ability in Bungie's Destiny franchise, that has the player launch a powerful explosive projectile at enemies.
  • In Halo: First Strike, Vice Admiral Danforth Whitcomb stated that the NOVA bomb on Reach had been activated on a timer. Though not stated, the bomb appears to have been disarmed at some point after its discovery, preventing it from going off until it was inadvertently reactivated during Halo: Ghosts of Onyx.
