IntroductionEditThe Plasma mortar fires huge bolts of superheated plasma which, when they hit, have a fairly large explosion radius. The weapon has a relatively slow rate of fire. It is extremely powerful, usually killing infantry in a single hit and can destroy just about anything on the battlefield in a minimal amount of shots. Its plasma projectile moves relatively slowly, making it more susceptible to gravity, causing it to fire in an arc, which allows for it to simply go over obstructions such as barricades and hills which can be effective in ambush attacks. The plasma bolt can be out maneuvered easily by a fast vehicle such as the Ghost or Mongoose. The mortar is very effective against dug in enemies, which can deplete the amount of resistance the Covenant ground troops have to face in battle.
The Wraith's Plasma Mortar serves as an excellent long range bombardment style projectile. The arching projectiles allow the Wraith to stay at a particular position, without the worry of having to aim projectiles around and over terrain.
In the Halo novels, the physical effect of plasma weapons result in extreme heat and the melting/boiling of enemy armour. This effect is never shown in the Halo games, with the plasma having an explosive reaction instead.
Medium Plasma MortarEdit

The medium plasma mortar is a smaller, less powerful variant of the Wraith's plasma mortar. It is equipped on the Revenant and makes its only appearance in Halo: Reach.
Heavy Plasma MortarEdit
- Main article: Type-26 Assault Gun Carriage
The Wraith is a mobile plasma mortar. In Halo: Combat Evolved, that was the sole purpose of the Wraith, lacking any other weapon systems. In Halo 2, the Wraith was armed with two plasma cannons for protection. In Halo 3, the Wraith was turned into an all out tank with its own gunner seat.

A giant stationary plasma mortar was seen destroying buildings in the Halo 2 E3 Demo video. Sergeant Banks called in an airstrike and a group of Longsword's flew in and destroyed it. Several smaller plasma mortars can be seen on the beaches of New Mombasa in the Halo 2, but they are never seen firing.
The United Nations Space Command also used a type of plasma mortar, but it was in prototype form upon Rhinos which were used in at least 2531. Five of these were used by Professor Ellen Anders to collapse a Covenant energy shield and reveal a Super Scarab, a Covenant superweapon, during the First Battle of Arcadia.
- Main article: Halo Wars
In Halo Wars, if you play as a Covenant leader (Ripa 'Moramee, Brute Chieftain or Regret), you can upgrade your turret to a plasma mortar. This version of the turret specializes in taking out infantry (Grunts, Marines, Hellbringers, Jackals, Spartans and Hunters). The Covenant Air Artillery, a unit cut from Halo Wars, would have also used the Plasma Mortar.
- A Plasma Mortar fires in an arc so it is somewhat difficult to hit a target. The further away you are, the higher you will have to aim to actually hit the target.
- Timing is critical, if perfected, it may flip a smaller vehicle over, allowing you to launch a second mortar and obliterate the vehicle and the crew.
- Due to its slow-moving nature, the Plasma bolt will be much easier to avoid than a human projectile.
- Remember that even if you are behind cover, you may still not be protected from the plasma's curved trajectory.
- Plasma mortars are usually used for close range in Multiplayer due to the difficulty of hitting people with the arc involved.
- In the Halo Series campaign, the Wraith's AI is so skilled with the plasma mortar that it can hit you from seemingly impossible distances. Keep moving.
- When a Plasma Mortar is discharged, it makes a distinctive whining noise as it flies through the air. Use this to your advantage, and keep moving. Chances are, you will be able to completely avoid the shot with some deft maneuvering.
- On larger maps like Valhalla, if you continuously launch volleys toward the enemy base, you will eventually get a kill. You can also kill teammates too, so be careful where the shots are placed.
- The cowbell skull will increase the splash damage of the plasma mortar bolts to such an extent that it can kill a fully shielded Spartan even if they are several meters away from the impact point.
- Plasma mortars might have been inspired by the Plasma Bugs in the film adaptation of Starship Troopers.
- As it is not a conventional artillery round, but a ball of ionized gasses contained in a magnetic envelope, traditional ballistics do not govern the mortar's arc. Most likely, the trajectory and speed of the projectile' can be controlled by the Wraith pilot, and the arcing path is the default setting for the mortar.
- In the Halo 3 Starry night trailer, plasma mortar bolts move faster than normal.
- During the level Quarantine Zone in Halo 2, several large plasma mortars can be seen firing opposite a couple of Sentinel Factory platforms, one plunging down, but it's never confirmed if these are from stationary plasma mortar cannons, or otherwise. However, due to the area containing the two Wraiths fighting Enforcers, and its close proximity with the destroyed remains of the factory, it is likely that they are the Wraiths' Plasma Mortars. It is even possible to see those same Wraiths fire at the remains of the factory, when the player destroys the Enforcers before the Wraiths are immobilized.
