The Death Stars, the Galactic Empire's ultimate terror weapons, were battle stations several hundred kilometers in diameter and mounting a directed energy super-laser capable of completely destroying a planet with a single shot. The Death Star was designed to allow Emperor Palpatine to more directly control the Galactic Empire through fear. In most instances, a Death Star was to be commanded by an officer called a Moff. Worn by the forces of the Galactic Empire, this all-purpose black cap includes aluminum Imperial disc.
