"It appears the enemy has some kind of new super weapon."
Crux in The Midnight Sun and Standoff in the Skies II

The Shock Cannon was an energy-based super weapon developed by Leasath and it was used during the Aurelian War.



One of the main weapons of the Gleipnir airborne fortress, the Shock Cannon was a meson-based air-to-ground weapon powered by a cyclotron-type particle accelerator within the aircraft itself, delivered through a disc-shaped device on its undercarriage, designed to operate under the same fuel-air explosive principle as the Shock Wave Ballistic Missile so as to avoid damage to itself. The non-indicative name of "cannon", reflecting its great power, was used by Leasath personnel as a term of convenience.[1]

Prior to firing, the Gleipnir spreads a cloud of explosive gas that is ignited by a directed meson discharge to the firing disc from the cyclotron, which is unable to produce enough energy to act as a weapon by itself. Unlike the Shock Wave Ballistic Missile, the weapon's energetic output could be modified to allow it to operate in adverse weather, making it more versatile than its missile-based counterpart. However, the immense amount of energy required to fire prevented it from being used simultaneously as optical camouflage,[1] leaving a loophole for attacks. 

A stand-alone version of the cannon was also equipped to Archelon Fortress as a last line of defense.

Aurelian War

The Shock Cannon was developed by Leasath during of after the conclusion of the Leasath Civil War, being installed on the Gleipnir as one of its primary close range weapons. A second model based on the same type of disc-shaped device was installed on the command building of Archelon Fortress, which was capable of faster recharging, likely because of an internal power source within the base itself.[2]

During the Aurelian War, the Shock Cannon was infrequently used by the Gleipnir, which instead favored SWBM attacks against the Aurelian military, leading its existence to be known only by small numbers of troops.[2]


  • The Spiridus, another airborne fortress which is featured in Ace Combat: Joint Assault, features many similarities with the Gleipnir. It uses a rail gun named Balaur, which can be considered a direct analog to the Shock Cannon. A stand-alone version of the Balaur was also built in Romania, similar to the Shock Cannon mounted on Archelon Fortress.
