This article is about the ground-based plasma mortars. For the plasma mortars mounted on Covenant starships, see Plasma bombardment mortar.

The plasma mortar, also known as energy mortar,[1] is a classification of plasma-based artillery weapon.[2]

The plasma mortar launches shaped blast of superheated plasma, which arc in a parabolic trajectory and explode violently upon impact.[3] As with any mortar weapon, the plasma mortar serves as an excellent long range bombardment style projectile. The arching projectiles allow the operator to stay at a particular position, without the worry of having to aim projectiles around or over terrain.

Since they can be mounted on a variety of emplacements or vehicles, plasma mortars are employed similarly in a variety of roles, including anti-personnel,[4] anti-vehicle, and shelling fortifications.[2]

Known types[edit]

Burst cannon[edit]

Main article: Ra'aam-pattern burst cannon

While originally designed as a naval weapon aboard aging warships of the Sangheili, the Ra'aam-pattern burst cannon was taken by Jul 'Mdama's Covenant and repurposed as an emplaced plasma mortar.[5]

Class-2 medium plasma mortar[edit]

Main article: Class-2 medium plasma mortar

The Class-2 medium plasma mortar is mounted on the rear of the Rizvum-pattern Revenant.[6][7] While charging, the plasma blast possesses a bluish tinge, though it is red when it is fired. The weapon has a less pronounced parabolic arc than its larger counterparts.[8]

Incendiary plasma mortar[edit]

Each N'weo-pattern Gigas craft is armed with two incendiary plasma mortars, allowing the fighter-bomber to deploy incendiary carpet bombs.[9]

Infantry-deployed energy mortar[edit]

There is a Covenant infantry-deployed energy mortar.[10] These mortars require at least a trio of Unggoy to assemble on-site, but once assembled, they can generate energy shielding for protection.[11]

Heavy plasma mortar[edit]

The heavy plasma mortar is the primary armament of the Wraith.[12][13] It launches a plasma blast that is typically a blue-white orb which travels slowly in the air.[3] However, upon impact, the plasma blast obliterates everything at the point of impact,[1] all the while leaving a large crater on ground in its wake.[3] The plasma mortar's main use lies in shelling and vehicular warfare,[14] but it is also fairly effective in closer engagements.[15] The heavy plasma mortar has seen numerous variations, including, but not limited to, the scorch plasma mortar on Ironclad Wraiths and an infusion-modified variant on Terror Wraiths.[16]

Plasma mortar[edit]

The seemingly standard variant of the plasma mortar fires medium-sized blasts of superheated plasma. While it was an optional armament on the Kewu Umppi'pa'-pattern citadel turret during the Human-Covenant War,[4][17] it is primarily mounted on the Banished’s Eklon'Dal Workshop Marauder.[18]

Siege plasma mortar[edit]

The siege plasma mortar is mounted on the Covenant's stationary Emp'seam-pattern Antlion and its Banished successor, the Eklon'Dal Workshop Antlion. The siege plasma mortar fires a devastating volley of plasma torpedoes[19] at an astonishing range, easily turning enemy fortifications into glassy craters.[17] The Banished variant is heavily augmented and overclocked to increase its effectiveness and range.[20]

Ultra-heavy plasma mortar[edit]

The ultra-heavy plasma mortar is mounted on the Covenant's stationary Zo'op-pattern Weevil, which provides fire support over large segments of enemy-contested area.[17]

XM4600 Zeus plasma munition howitzer[edit]

Main article: XM4600 Zeus plasma munition howitzer

The XM4600 Zeus plasma munition howitzer is the closest equivalent to a plasma mortar employed by the United Nations Space Command. Reverse-engineered from Covenant technology, the weapon fires a 320mm artillery shell with fuel rod filler that unleashes a powerful barrage of plasma at its targets.[21][22] It is mounted on M145D Rhino prototypes, which were used in at least 2531, when five of these were used by Professor Ellen Anders to collapse a Covenant energy shield during the Battle of Arcadia.[23]

Production notes[edit]

  • Plasma mortars may have been inspired by the Plasma Bugs in the film adaptation of Starship Troopers.
  • The Covenant Air Artillery, a unit cut from Halo Wars, would have used three plasma mortars.
  • Early Halo: Reach concept art by Glenn Israel featured a Covenant mortar held in a manner akin to the Brute Shot or Pek-pattern plasma cannon, or able to be deployed as a static emplacement. Some of the sketches of the weapon drew influences from the plasma mortars on Revenants and Wraiths.[24]
