A particle disintegrator warhead aboard a lightspeed torpedo fired from the Galaxy Gun A type of warhead known as a particle disintegrator warhead was used on lightspeed torpedoes.
These warheads were placed at the front of the enormous lightspeed torpedoes launched from the Galactic Empire's Galaxy Gun superweapon. This missile's power core was connected to the warhead, which was energized by it when the torpedo approached its target world. The warhead would initiate a sequence of nucleonic chain reactions upon impacting a planet's surface, consuming everything in its path and explosively transforming matter into energy.
The warhead's power could be adjusted. When set to maximum power, the warhead could obliterate an entire planet because the nucleonic reactions continued until all matter was consumed. However, when set to lower power levels, the warheads could selectively destroy cities and military installations while preserving the rest of the planet's surface.
