The Evil Empire depends heavily on fighters for attacking enemies. They have only one ship type that can launch torpedoes. Most of the Empire's ships are very large and expensive. The Empire's battle carrier is the largest and most heavily armored fighter carrier in the universe it has 10 beam weapon banks, which is most impressive for a carrier.
The captains of all ships in the Evil Empire can use the "Dark Sense" to detect enemy colonists living on planets within a configured range. The "Dark Sense" is never wrong! Nothing can hide a planet from the power of the "Dark Sense."
They can build the Super Star Destroyer assault ship that can take over enemy planets just by dropping 10 clans onto the planet.
