Plasma weaponry

Plasma weaponry refers to directed energy weapons that utilise plasma to do damage to a target. Covenant military forces use plasma in weapons to great effect.

Operation

Plasma weapons contain and guide the plasma in the form of a single bolt, beam, or continuous stream. Plasma is stabilized using magnetic fields. Without the field, the plasma dissipates too quickly to be of any real use. The field controls and contains the plasma, without interfering with firing. The energy sword is an example of this technology, as the magnetic field holds the blade together while allowing it to cut through objects.

This is also how the plasma pistol's overcharge shot works: A small magnetic generator is installed in the hilt of the pistol and, when fired, the bolt tracks its target using a very simple motion tracking system built into the magnetic generator which alters the field to make the plasma move. A larger version of this effect is seen in the plasma turrets used by Covenant capital ships.

Defense against plasma weaponry

Complete armor protection against plasma is generally difficult to accomplish due to plasma's high damage ratio. The armor used by the UNSC Marine Corps and UNSC Army usually provides good protection from plasma, but only to a certain extent. A series of hits from a plasma weapon will literally melt or burn the armor, rendering it useless. Likewise, the Spartans' MJOLNIR armor will eventually give way to the plasma. Newer versions of the MJOLNIR armor boast energy shields, which provide additional protection from plasma, although shielding systems can be completely depleted by sustained plasma fire, or a single, overcharged bolt.

The armor of neither Covenant nor UNSC warships provides significant protection against plasma, which will melt through the hulls of both. Covenant plasma torpedoes have a temperature of approximately 3,000 degrees Celsius,^[1] while titanium, a key component of UNSC ship armor, has a melting point of 1668 degrees Celsius.Cite error: Invalid <ref> tag; invalid names, e.g. too many Covenant species have developed a natural resistance against the radiation emitted by their plasma weapons, a form of "forced evolution". During the Human-Covenant War, UNSC scientists studied this phenomenon in an attempt to use it to their advantage, such as helping in the treatment of plasma burns on humans.^[2]

The UNSC has yet to develop its own plasma weaponry, instead using more conventional projectile-based weapon systems. However, the UNSC has been seen to operate captured Covenant plasma weapons, and in one case, UNSC forces were able to dramatically improve the lethality of a captured Covenant starship's plasma turrets without significant technical modifications.^[3] There was an attempt to produce a tank with plasma-based weaponry for the UNSC armed services, but it was abandoned, falling back on projectile weaponry.^[4]
