'''Plasma torpedoes''' are a type of [[plasma]] naval [[Plasma weaponry|weaponry]] used by the [[Covenant starship|starships]] of the [[Covenant]] and its [[Covenant remnants|remnants]]. They are one of the staple weapons of most larger warships, though may be found in use on smaller vessels and even [[Space fighter|fighters/bombers]] - serving as a rough equivalent to the [[missile]]s heavily employed by the warships of [[human]]ity. | |||

'''Plasma torpedoes''' are a type of [[plasma]] [[Plasma weaponry| | |||
== | A plasma torpedo is itself a solid-core cylindrical projectile fired from a silo located on the ship's exterior hull.{{Ref/Book|Id=WFG|HWF|Section=Glossary|Page=92}}{{Ref/Book|Id=Enc22|Enc22|Page=261}} When preparing to fire, a core is "lit" with plasma siphoned from the ship's [[pinch fusion reactor]], with the energy contained and enveloped by the core in a sheath. The torpedo is then fired and guided to its target via a command link with the firing warship, before detonating at the target.{{Ref/Reuse|Enc22}} Upon contact, a plasma torpedo causes severe damage to the target, boiling armor or overloading [[Energy shielding|shields]]. | ||
The torpedoes | ==Overview== | ||
===Design details=== | |||
The systems used to fire plasma torpedoes are known as plasma torpedo silos{{Ref/Reuse|WFKet}} or plasma turrets, which are located along the hull of the ship. At least on some Covenant vessels, the turret or "silo" is antenna-like in appearance and is installed on universal joints often located along the lateral sides of the ship.<ref>'''Halo: First Strike''', ''pages 36-37''</ref> The torpedoes are typically described as red or purple in color and short, with a ball-like head and a trail. | |||
The torpedoes themselves are initially stored aboard Covenant vessels as inert cores, which are roughly cylindrical objects that range between 3–5 meters in total length. For ''Ket''-pattern {{Pattern|Ket|battlecruiser}}s such as the ''[[Truth and Reconciliation]]'' and probably other ships that are armed with plasma torpedo silos, thousands of these inert cores are carefully packaged and stored in munitions racks before each deployment of the vessel.{{Ref/Reuse|WFKet}} | |||
==Operation== | Although normally launched from starships, self-guiding plasma torpedoes can be deployed as mines to deny strategic locations to enemy forces.{{Ref/Novel|HOblv|Chapter=Epilogue}} | ||
===Operation=== | |||

The inert plasma torpedo cores are ignited in a pinched magnetic field by energy supplied from the ship's [[pinch fusion reactor]]s and guided by magnetic coils. When the weapon charges, a line of superheated plasma forms alongside the exterior plasma conduit adjoining the turret.<ref>'''Halo: Ghosts of Onyx''', ''pages 193, 198''</ref> Once fully charged, the now ignited plasma torpedo core fires outward at its target. The torpedo is guided towards its target by a long-reaching magnetic field projected by the emitter.<ref name="fs266">'''Halo: First Strike''', ''page 266''</ref> Upon impact, the torpedo penetrates most unshielded starships, burning through internal decks and structures, thus causing heavy damage on the target. | The inert plasma torpedo cores are ignited in a pinched magnetic field by energy supplied from the ship's [[pinch fusion reactor]]s and guided by magnetic coils.

As with many other examples of their technology, the Covenant themselves only understand a fraction of the underlying science involved with the operation of the plasma turret. As a result, despite their overwhelming power against human ships, the Covenant's methods of using their weapons systems are highly inefficient, relying on crude brute-force calculations and causing wasteful energy expenditure due to their slow operation; this is also why the turrets glow before firing. When in control of the Covenant ship ''[[Ascendant Justice]]'', UNSC [[smart AI|AI]] [[Cortana]] was able to use the vessel's plasma turrets to their full potential; she created an entirely new system to control the plasma, using [[electromagnetic pulse]]s to direct the plasma into precision beams within a microsecond. This enabled her to use the weapons with far greater power and precision than the Covenant themselves, cutting through Covenant vessels like a scalpel, not unlike an [[energy projector]]. According to Cortana, she could have improved the plasma turrets even further had the Covenant ship possessed better electromagnetic systems.<ref name="fs171">'''Halo: First Strike''', ''pages 171-172''</ref> | As with many other examples of their technology, the Covenant themselves only understand a fraction of the underlying science involved with the operation of the plasma turret.

The magnetic coils used in a [[Magnetic Accelerator Cannon|MAC gun]] can be used to shape and guide the plasma fired by a plasma turret; this was seen before the [[Massacre at Eridanus Secundus]], when the {{UNSCShip|Gettysburg}}'s magnetic coils were used to guide plasma torpedoes fired by the ''Ascendant Justice'''s turrets.<ref>'''Halo: First Strike''', ''pages 264-266''</ref> | The magnetic coils used in a [[Magnetic Accelerator Cannon|MAC gun]] can be used to shape and guide the plasma fired by a plasma turret; this was seen before the [[Massacre at Eridanus Secundus]], when the {{UNSCShip|Gettysburg}}'s magnetic coils were used to guide plasma torpedoes fired by the ''Ascendant Justice''{{'}}s turrets.<ref>'''Halo: First Strike''', ''pages 264-266''</ref> | ||

While the term "plasma torpedo" is used throughout the novels, the weapons used to fire the torpedoes are only identified as "plasma turrets" in ''[[Halo: First Strike]]'', which also describes their operational mechanisms in detail.

However, it should be acknowledged that the terms "cannon" and "turret" are rather general and are likely used descriptively rather than being restricted to specific weapon systems. From the context in ''Contact Harvest'', for example, it is apparent that the ''Rapid Conversion'''s "plasma cannon" is in fact referring to the ship's [[energy projector]]. Therefore it can be assumed there is a substantial amount of overlap between the terms. | However, it should be acknowledged that the terms "cannon" and "turret" are rather general and are likely used descriptively rather than being restricted to specific weapon systems.

''[[Halo: Combat Evolved]]'', ''[[Halo 3]]'' and ''[[Halo: Reach]]'' depict Covenant starships firing blue or blue-purple bolts of plasma which are seemingly unguided. Meanwhile, the novels consistently describe plasma torpedoes as being red as well as highly maneuverable. Given these differences, it is likely that the plasma weapons depicted in the games are in fact representative of the "plasma cannons" listed in the ''Song of Retribution''<nowiki>'</nowiki>s arsenal rather than plasma torpedoes. ''Halo: Combat Evolved'' depicts the {{UNSCShip|Pillar of Autumn}} being struck by numerous blue plasma bolts.
