'''Melta Weapons''' are heat-based weapons which work by sub-atomic agitation of the air. Targets on the receiving end are heated to the point of being vaporised. The effect on flesh is fearsome to say the least, while vehicles can be reduced to molten slag. Most melta weapons use highly pressurized pyrum-petrol gases with a two part injection system which forces the gases into a molecular state, which will vaporise just about anything. Unfortunately, due to the high power consumption and range dissipation, the weapon is only effective over very short distances, but anything caught in the blast is likely to be destroyed.{{cite this}}

Although short-ranged and slow to fire, they are prized for their power against armoured vehicles. They are also considered a good alternative to [[plasma Weapons|plasma weapons]], which are unreliable and capable of killing their user. Besides the roar of the explosive vaporising of the target's moisture, melta weapons themselves make little noise when firing. Given their fairly quiet and very effective nature, infiltrating parties make use of melta weapons to destroy enemy vehicles before they get a chance to fight on the battlefield.{{cite this}}

Many races make use of the same basic technology. In the Imperium they are called meltas, and often referred to as 'fusion guns', 'melters', 'cookers' and 'vape guns'. Equivalent weapons used by other races have similar effects, although sometimes completely different technology and methods of operation. Both the [[Tau]] and [[Eldar]] use melta weapons, primarily for tank hunting like the [[Imperium]].{{cite this}}

The '''Meltagun''' is the most commonly seen melta weapon in use by the Imperium and is commonly found throughout all of the Imperium's fighting forces including the [[Imperial Guard]], [[Space Marine]]s, [[Ordo Hereticus]] and [[Adepta Sororitas]].{{cite this}}

The '''Multi-melta''' is a heavier version found primarily on vehicles and occasionally carried by [[Space Marine]] Devastator squads and [[Sisters of Battle]].{{cite this}}

The '''Inferno Pistol''' is a very rare and smaller melta weapon, used only by the agents of the [[Inquisition]] ([[Ordo Hereticus]] and [[Ordo Malleus]]) and a select few [[Space Marines]] (Commander [[Dante]] of the [[Blood Angels]] [[Chapter]]).{{cite this}}

The '''Melta Cannon''' is a large vehicle-mounted melta weapon, able to destroy several targets at once. It can be found on the [[Devil Dog]], a variant of the [[Hellhound]]. An even larger version of the [[Melta Cannon (Titan)|Melta Cannon]] is mounted on several classes of [[Imperial Titan]].^{{{Fn|3,}}{{Fn|4}}}

'''Melta Torpedoes''' are powerful incendiary weapons used by [[Imperial Navy]] warships.^{{Fn|6}}

The '''Fire Pike''' is an Eldar weapon used by the Fire Dragon's [[Exarch]].{{cite this}}

The '''Fusion Gun''' is an [[Eldar]] weapon used by the [[Fire Dragons]] Aspect and [[Guardian#Storm Guardian|Storm Guardians]].{{cite this}}

The '''Fusion Pistol''' is an [[Eldar]] weapon used by [[Harlequins]] and [[Autarch]]s.{{cite this}}

The '''Fusion Blaster''' is a [[Tau]] weapon and is similar to the Imperial version in power.{{cite this}}

The Fusion Cascade is a newly developed Tau weapon which fires in bursts. Due to the increase in amount, the power of each shot is less than the Imperial equivalent. It is equipped on the [[Battlesuit #XV-9-01 Armour|new Battlesuits]].{{cite this}}

The '''Heat Cannon''' is a Necron weapon typically mounted on [[Sentry Pylon]]s.{{cite this}}

The '''Heat Ray''' is a Necron weapon mounted on [[Triarch Stalker]]s and capable of anti-tank and anti-infantry modes of fire.^{{Fn|5}} ==See Also==*[[List of Lists]]
