- "Miniaturized Death Star tech."
A superlaser siege cannon or battering ram cannon was a heavy artillery weapon deployed by the First Order, capable of penetrating enemy defenses.
The superlaser siege cannon was a piece of miniaturized Death Star technology capable of firing a devastating energy pulse along a targeting tracer beam to cause a powerful detonation upon impact. The two-hundred-meter cannon required support vehicles to maneuver it into position during sieges; the weapon was airlifted onto battlefields, and was towed on ultra-dense cables by All Terrain Heavy Haulers. When positioned, the cannon deployed retractable stabilizing outriggers to ground its bulk, and was armed with topside defense turrets for protection while charging.
A siege cannon was deployed by the First Order during the Battle of Crait, used to blow a hole in the blast door of the Crait outpost sheltering Resistance personnel. V-4X-D ski speeders attempted to destroy the weapon, and Finn set out on a kamikaze run into the cannon's barrel, but was intercepted by Rose Tico at the last second. The cannon fired unopposed, breaching the Resistance's defenses and ultimately allowing Kylo Ren entry into the outpost.
