Torpedo Sphere

"I've been monitoring equipment suppliers and I'm telling you we should be worried."

- Colonel Haxen Delto, in a report to General Airen Cracken

Torpedo Spheres were large, disk-shaped siege platforms of the Imperial Navy 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 Colonel Haxen Delto, and was later integrated into the Rebel Files, a secured Rebel Alliance archive of sensitive information that was rediscovered decades after the Galactic Civil War.

Characteristics
"These two-kilometer siege platforms are armed with hundreds of proton torpedo launchers that can crack any planetary shield, given time and patience."

- Colonel Haxen Delto in a report to General Airen Cracken

The Imperial Navy Torpedo Sphere was a two-kilometer-long, disk-shaped siege platform in service to the Galactic Empire. Sometimes referred to as a battlemoon, it had a depression that emitted a red light and the hull had dark and light sections of gray. The Torpedo Sphere was equipped with hundreds of proton torpedo launchers that, given enough time, could breach through any planetary shield. A group of Torpedo Spheres was referred to as a constellation.

History
"Transmitter traffic from Loronar is spiking. We're going to be looking at a whole constellation of battlemoons if the Empire can pump these out."

- Haxen Delto to Airen Cracken in a report

Sometime between the years 5 BBY and 0 BBY, the intelligence branch of the Rebel Alliance witnessed a spike in transmitter traffic from Loronar, a world in the Colonies region of the galaxy. With this information, supplemented with data on equipment suppliers, Colonel Haxen Delto of the communications section of Intelligence deduced that the Empire could produce a constellation of the battlemoons, and expressed to Chief of Rebel Intelligence General Airen Cracken that they should be worried.

Delto's report was articulated into The Rebel Files, a data archive that contained a non-electronic copy of sensitive information which would be unearthed in the ruins of the Tak-Beam complex, a former Alliance base located on the Mid Rim world of Durkteel, by a construction team employed to build a comm tower in 34 ABY. . It made its way to the planetary governor, Vaxvissh Kal Ness, and eventually reached General Leia Organa of the Resistance.
