A CCS-class Battlecruiser firing an Energy Projector.
The titanic vessel Keyes had seen before was back. It fired its brilliant blue-white beam - a lance across space - that struck the destroyer Herodotus, one hundred thousand kilometers distant. The beam cut clean through the ship, stem to stern, dissecting her.[1]

The Energy Projector is a Covenant weapon used exclusively by large ships. It fires a thin beam of energized matter which has very long range and is extremely accurate and destructive, capable of destroying ships effortlessly and "glassing" planets, systematically rendering them sterile and incapable of sustaining life.



The Energy Projector was first encountered during the Battle of Harvest, where it was used by a Covenant Battleship, a ship that was seen for the first time. It is more frequently seen several months later, where Regret's Carrier uses one to destroy the Prophet's temple after he had been assassinated by the Master Chief on Delta Halo. In Halo 3, parts of Eastern Africa, Kenya and the city of Voi were glassed by Rtas' Vadum to stop the Flood infestation.


The weapon can fire a thin beam of extremely powerful and energetic particles. It is possible to predict when it was about to fire as it typically charges the beam up before firing. The beam has an effective range of over 100,000 kilometres, longer even than that of a UNSC MAC gun used by Orbital Defense Platforms. It is described as looking like pulse lasers, but tinged silver white, which is compared to the scintillation effect that is seen when a Covenant ship's shields are hit. The long range allowed a ship armed with this weapon to 'snipe' targets during ship-to-ship combat, albeit less effectively. The weapon has been observed to gut UNSC ships from stem to stern, such as the Frigate Gettysburg over Reach.[1][2] It also seems to be able to expand in size, depending on the size of the ship.


The Energy Projector's beam is able to take down the shields of a Covenant Frigate or Covenant Destroyer with a single hit.

Against UNSC vessels, the weapon was able to pierce dozens of Titanium-A armor layers with comparative ease, rendering any form of physical solid defense useless. Therefore, a single hit or perforation could potentially disable or destroy vital systems, such as the MAC Cannon or engines, rendering the ship useless for combat (as seen at the Battle of Earth when a single shot from an Assault Carrier crippled a Marathon-class cruiser), or if the shot was in a critical area, such as the reactors of a ship; it could destroy the ship completely.

The beam is similar to the Particle Beam Rifle on a larger scale in how and what it fires. It is also speculated that the beam can be focused to varying degrees. In space, they can be focused to a smaller, therefore more powerful beam generally used to decimate enemy ship fleets from afar. It also seems to drain all or most of the energy in a Covenant ship for a brief period unless the ship is big enough to supply the power without too much of a drain. This weapon is also used for glassing enemy planets.

When glassing a planet, the beam causes atmospheric and biospheric destruction by exciting the atoms in the air, thus scorching land and air life, and evaporating water with ease, suffocating aquatic life and destabilizing the planet's surface temperature. Therefore, merely firing it through the air would cause biospheric destruction on a planetary scale. In addition, the excitement of atoms could chemically alter the atmosphere or even blow it away. The combined effect can make the planet permanently inhospitable to life, as was the case with Harvest.


According to Fred-104, only the "big ships have them." Ships of the Reverence-class , the Covenant Supercruiser, and the Assault Carrier were known to wield this weapon. Other large ship classes, such as the Covenant Supercarrier, are very likely to have it too. The CCS-class Battlecruiser have them too, albeit they have only two projectors, located under the ships bow, and under its middle. The Prophet of Regret's cleansing beam acts as a mini-Energy Projector in Halo Wars.


  • The weapon's beam has a similar appearance to the Particle Beam Rifle's Beam, and also has a similar purpose: To land a precise shot into critical areas of the enemy, and works using the same principle: accelerate small amounts of mass to near light speed to burn through human ships or human heads respectively.
  • In Halo Wars, the color of the Energy Projector in based on your team color.
  • Even though the energy projector is capable of cutting through the armor of several UNSC ships at a time, it is seen as only a needle thin beam going at light speed.

Usage and history
"These weapons shall serve as the primary cleansing instrument of our warships. With them, we shall burn a literal path through the parasite's very core and set fire to their innards."
Darth Azazel

Hellspawn-class Directed Energy Beams, mostly better known as Energy Projectors, were massively powerful energy weapons designed to devastate even the most resilient of defensive measures. Conceived by both Darth Azazel and Kostya Vo, the relatively modest sized cannons were most infamous for being utilized as the primary armament of the Ash'rak Starfleet, where they were used to literally burn several planets to an unrecognizable crisp from orbit.

Despite their power, popularity amongest the Ash'rak, and accuracy, however, the Hellspawns' lack of great range and need for a considerable power supply in order to be truly effective kept most other navies from purchasing them, as the arguably less powerful but less expensive and more familiar turbolaser could be bourght, maintained, and utilized more easily. Nevertheless, on certain vessels and installations, the Hellspawn was a expected sight.


Instead of firing bursts of energy like most directed energy weapons, Hellspawn, or Energy Projectors, released a narrow, highly focalized beam of weaponized plasma energies at the inteneded target. Typically fired in bursts to avoid overheating, this beam was focused to such intensity that it could easily punch through even the toughest shields with just a single shot. After taking down an enemie's shields, subsequent blasts would literall melt through most durasteel hulls as comparable to a lightsaber through flesh. However, this extraordinary destructive power came at a price; each shot released such enormous levels of heat that special cryogenic units were required to spray the cannon's barrel after each shot, a process that took ten precious seconds. Without these cryogenic units, the weapon could still be shot, but with greater intervals between firing; as much as three to six minutes.

In addition to the dangerous overheat potentiality, few shipboard recators could actually even produce the huge amounts of energy that the cannon required in order to unleash such a powerful, devastating beam of plasma. While vessels such as Star Destroyers with their massive solar ionization plants could easily give several Energy Projectors the fuel they required, but a CR90 Corvette might have had trouble supporting just one of the cannons onboard. Despite usually being reserved for use against the most powerful of enemy vessels, a few blasts into a starfighter formation could at least vaporize a few of the craft with the beams massive backwash of energy and shockwave.

Although such considerable, mounted cannons usually took a small amount of time to come online and charge, the Energy Projector possessed a distinct advantage over turbolasers in that it could be brought online, charged with energy for a shot, and fired with pinpoint accuracy within just three seconds. This remarkable set-up and charge time usually gave a trained crew of a vessel armed with energy projectors a split-second advantage over they're enemy, but this did not make every battle a guaranteed victory. Similar to standard turbolasers, Hellspawn were usually completely ineffective against tiny craft such as starfighters. More agile capital ships could also dodge the blunt of a strike or otherwise avoid the beam altogether before it had the chance to hit them, but such maneuvers required the deft hands of a good helmsman to pull off.
