Torpedo Spheres were allegedly large, disk-shaped siege platforms of the Galactic Empire that were armed with hundreds of proton torpedo launchers. Given enough time, the battle stations could crack through any planetary shield. The Torpedo Sphere was featured in a report on Imperial weapons projects by Rebel Alliance Colonel Haxen Delto, which was later integrated into The Rebel Files, an archive of sensitive information that was rediscovered by the Resistance decades after the Galactic Civil War.

According to a Rebel Alliance report and analysis, the Torpedo Sphere was a two-kilometer-long, disk-shaped siege platform in the Galactic Empire‘s service. The Alliance report considered the battle station to be a superweapon and also referred to it as a «battlemoon.» An accompanying illustration depicted the Torpedo Sphere as having a depression that emitted a red light and a hull with dark and light sections of gray. The Torpedo Sphere was allegedly equipped with hundreds of proton torpedo launchers that, given enough time, could breach any planetary shield. A group of Torpedo Spheres was referred to as a «constellation.

The Torpedo Sphere was first introduced to the new Star Warscanon in Star Wars: The Rebel Files, a box set and reference book authored by Daniel Wallace and illustrated by Joe Corroney.^[1] The Torpedo Sphere was originally created for the Star Wars Legends adventure book Black Ice, written by Paul Murphy and Bill Slavicsek, illustrated by Bob Dvorak, and published by West End Games in 1990 as part of Star Wars: The Roleplaying Game.
