This article describes the superweapon used by the Gleipnir. For the player-equipped special weapon, see Long Range Shock Wave Missile.

The Shock Wave Ballistic Missile (衝撃波弾道ミサイル Shōgekiha dandō misairu, acronym SWBM) is a type of long-range missile designed by Leasath. It was utilized during the Aurelian War as the main weapon of the airborne fortress Gleipnir.


The Shock Wave Ballistic Missile is a type of modified ballistic missile, hence its name, which carries a small, disposable cyclotron accelerator, akin to the one used by the Gleipnir's other main weapon, the Shock Cannon. The SWBM carries a type of meson "fuel", which is dispersed by the missile upon reaching a target. When the missile impact occurs, the fuel ignites, causing a massive energy explosion. The shockwave spreads in a horizontal motion, destroying any aircraft flying at relatively high altitudes. However, as a result of air pressure differences, the blast wave will not have any effect at low altitudes.[1]


The Shock Wave Ballistic Missile is a special ballistic missile manufactured by Leasath prior to the Aurelian War. It was designed to be deployed by Leasath's airborne fortress, the Gleipnir and its prototype, the Gandr. A smaller version of the missile was later designed to be utilized by the experimental super-fighter Fenrir, but never saw deployment.

Aurelian War

The Shock Wave Ballistic Missile served as the Gleipnir's main weapon throughout the course of the war. During the opening stages of the war, Gandr used it to battle Falco Squadron, but the prototype aerial warship was shot down by the Aurelian aces.

The first known deployment of the SWBM by the Gleipnir during the war came during the Gleipnir's attack on Gryphus Squadron at Cape Aubrey. Following the destruction of a Leasath bomber squadron sent to destroy the air base, the Gleipnir fired a missile at the Aurelian fighters that shot them down, destroying nearly the entire squadron in a single strike. Later, the SWBM was utilized to attack Gryphus Squadron at Stand Canyon, to prevent them from providing air support to the Aurelian Davis Unit trapped there.

The SWBM's final known use in the war came during the battle of Santa Elva, where the Gleipnir used them to attempt to ward off Gryphus Squadron during an Aurelian operation to capture the key city. However, Gryphus 1 destroyed all of the Gleipnir's SWBM launching ports, and later destroyed the airborne fortress. The Gleipnir crashed into the Lenal River, ending the threat of the SWBM for good.



  • Ace Combat: Joint Assault features a weapon called the Hi-TASM, which is virtually identical to the SWBM. However, the former takes an slightly more realistic approach by using a thermobaric warhead, as opposed to the cyclotron technology used by the Gleipnir.
  • Due to utilizing mesons, a subatomic particle, in its fuel-air explosive design, the SWBM can, by definition, be considered a nuclear weapon.
