Alderaan shield bunker

"The Star Fortress is the heart of Zakuul's treachery on Alderaan. With it removed, this world might have a chance to rebuild. But the battle station is protected by a powerful shield generator here on the surface. We must eliminate it, first."

- Choza Raabat

After the end of their conquest of the galaxy around 3639 BBY, the Eternal Empire of the planet Zakuul built a shield bunker in the Juran Mountains on the planet Alderaan to support the Star Fortress that they placed in geosynchronous orbit above the bunker. Commanded by ZK-723S, an elite Skytrooper, the bunker and its deflector shield generator was protected by powerful defensive emplacements, walkers, and Zakuulan military forces. Around 3635 BBY, the Outlander&mdash;leader of an Alliance against Zakuul&mdash;rallied the local resistance against the Eternal Empire and organized a bombardment of the bunker, allowing the Outlander and the Jedi Choza Raabat to infiltrate and destroy the bunker and thus expose the Star Fortress.

Behind the scenes
The shield bunker on Alderaan was first added to the video game Star Wars: The Old Republic in Knights of the Fallen Empire, a 2015 Digital Expansion.
