The Armageddon was a StoneCrusher-class WarMasters and was equipped with an engine and a hyperdrive. It was armed with spectrum lasers and dibber missiles, and shielded with electrostatic barriers.
The Armageddon took part in the final battle of Jixtus's plan over the planet Sunrise. The warship was attacked by Chiss heavy cruiser Springhawks laser fire and a small gunboat known as Paccian Four crewed by the Paccosh species.
The Armageddon intended to overwhelm the gunboat with a salvo of dibber missiles to be able to focus on the larger Chiss cruiser; however, Senior Captain Thrawn, who was in command of the entire Chiss battle line, had anticipated this, and so the Springhawk was able to save the gunboat with a plasma sphere they had fired alongside their earlier spectrum laser attack. The Armageddons lead dibber missiles slammed directly into the plasma sphere, causing the whole cluster of missiles to explode too far away from Paccian Four to damage it, and close enough to the Armageddon to damage its targeting sensors. The paccian gunboat then flew straight through the debris cloud of the dibbers and devastated the whole flank of the Armageddon with laser fire, effectively blinding the Grysk ship on that side.
The Armageddon continued its fight with the Springhawk, attacking it with laser fire and dibbers until the Chiss ship turned and tried to flee the confrontation. Since it was on its route to attack two already damaged Grysk Prism-class BattleChiefs warships, the Armageddon pursued it in order to destroy it, falling right into a trap. The Clarr light cruiser Orisson and the Chiss heavy cruiser Grayshrike were ready to ambush the Armageddon, facing each other bow-to-bow in a five kilometer distance. The Springhawk was about to pass right between them, as would the Armageddon as it followed the Chiss ship.
Both the Orisson and the Grayshrike fired two breacher missiles at each other. As the commander of the Armageddon realized that the breachers would harmlessly pass in front of the ship, the Armageddon continued its pursuit of the Springhawk without slowing down. However, the breachers slammed into each other directly in front of the Armageddon, which slammed into a cloud of acid produced by the breachers' destruction. Damaged and unable to fight back, the Armageddon was then destroyed by both the Springhawk and the Orisson.
