Base Delta Zero

"All your base delta zero are belong to us!"

- Darth Vader

Base Delta Zero, or bΔ 0, was the highest setting of Imperial orbital bombardment. During a Base Delta Zero operation, an orbiting Star Destroyers would pound the planet in question with all of its weapons, burning up the atmosphere and slagging some of the upper crust, converting a once-luscious planet into a bubbling, steaming iron ball floating in the unforgiving dark void of space.

Despite its potential for destructive power, Base Delta Zero was generally considered a poor substitute for more thorough forms of planetary destruction by the Imperial Navy. After all, they've got a point - who needs plain old orbital bombardment if you've got the Death Star, the Sun Crusher, the Galaxy Gun, and Centerpoint Station?
