An airbase was a type of military installation. By 5 BBY, the Imperial Navy maintained an airbase known as the Steergard Naval Yard in Steergard. The airbase was attacked by Anto Kreegyr's group, which resulted in the attackers' overwhelming defeat, as the Imperial Security Bureau was made aware of their plans beforehand. The Aldhani Garrison maintained another airbase hosting the Alkenzi Air Command on the planet Aldhani.
