There is more information available on this subject atDirected-energy weapon on theEnglish Wikipedia.

Adirected-energy weapon (DEW) is a type of weapon that uses a non-solid projectile with a high enthalpy (kinetic and thermal energy) rather than solid ballistic ammunition. It transfers energy to a target for the desired effect.

Lasers[edit]

The UNSC's only infantry laser weapon, theSpartan Laser orGalilean.

Main article:Laser

Lasers are used for a wide array of functions, ranging from repair equipment to weaponry.Pulse laser turrets are standard armament on Covenant warships and, unusually,UNSC Prowlers, and are used for precision strikes against small targets, intercepting incoming missiles and fighters,^[1] and general point-defense. Other lasers are used to repair equipment by both the Covenant,^[2] and the UNSC^[3] while the only infantry-portable laser weapon is used by the UNSC, theM6 Grindell/Galilean Nonlinear Rifle or "Spartan Laser". During the Human-Covenant War, the UNSC began using nuclear bomb-pumped X-ray lasers as warheads for anti-ship missiles, such as theM4020 Bident used byEpoch-class heavy carriers.^[4] In the post-war era,Hannibal Weapon Systems has experimented with mounting laser weaponry on its testbedXM820B4 Scorpion tanks.^[5]

Plasma[edit]

One of the most commonly used directed-energy weapons, theOkarda'phaa-pattern plasma rifle.

Main article:Plasma weaponry

The Covenant's most common weapon type, however, is superheated plasma that is contained within a controlled magnetic field, able to be guided to a target and dealing heavy damage. Ship-mounted plasma weapons can launch torpedoes, capable of tracking their targets with precision, making them devastating in ship-to-ship combat, or can fire very large streams of plasma from afar to "glass" a planet's surface from orbit. Vehicle-mounted plasma weapons usually have a high rate of fire, but lack guidance systems. Infantry weapons commonly use guided plasma, such as the Plasma Rifle,Plasma Pistol, and thePlasma Grenade. Towards the end of the Human-Covenant War, the UNSC began using nuclear-pumped "focused plasma spears" in ship-to-ship missile warheads.^[4]

Electrolaser[edit]

Weapons that make use of electrolasers include theBanished-madeSicatt Workshop shock rifle. This weapon's electrolasers consist of electromagnetically-guided plasma beams capable of disabling electronics components of vehicles and evenMJOLNIR Powered Assault Armor viaelectromagnetic pulse.^[6][7]

Particle beam weapons[edit]

The Covenant also uses accelerated particles as weaponry, such as the devastating capital ship mountedenergy projector and the infantryType-50 particle beam rifle. These weapons use charged or neutral particles and may appear similar to lasers though the differences are extensive. Though humans have an understanding of accelerated particle technology they have not yet used it for weaponry.

Ionized Particles[edit]

Not much is known about this type of weapon other than it is exclusive to the Forerunners and shares traits from both plasma and particle beam weapons.Aggressor Sentinels use a powerful continuous firing beam type called theSentinel Beam as their main weapons. ManyPromethean weapons are this type and have a tendency to disintegrate targets, and bounce off solid surfaces. The ionized particles fired by these weapons can come in a variety of colors, including gold, orange, purple, and blue.

Hard light[edit]

Weaponized hard light seems to be exclusive to the Forerunners as the Covenant never managed to fully reverse-engineer the technology.
