The command ship's were known to have a self-destruct mechanism installed to prevent the ship from falling into the enemy's hands.
The ship served as one of the command ships of the Reconstituted Sith Empire during the Galactic War between the Sith Empire and the Galactic Republic.
In 3640 BBY a planetary command ship landed at a local spaceport on the planet Kalandis Seven during the Battle of Kalandis Seven. Republic Special Forces Division Colonel Jace Malcom and Republic trooper Sergeant Shanra Immel and her squad invaded the starport with orders to destroy it. Colonel Malcom amended the plan to include the capture of the command ship they saw land. Malcom infiltrated the hangar and the command ship, whilst Immel and her squad were planting target beacons through the spaceport. On the bridge Malcom saw three Sith officers and a female Sith overseer, and engaged the Sith overseer in combat. As the overseer lay dying she initiated the self-destruct mechanism aboard the ship. Malcom evacuated the spaceport as the ship was destroyed.
The planetary command ship was first mentioned as a Sith command ship in Pablo Hidalgo's reference book The Essential Reader's Companion which was released on October 2, 2012. The ship first appeared and was first identified as a Planetary command ship in Alexander Freed's short story The Last Battle of Colonel Jace Malcom which was published in Star Wars Insider 137 which was released on October 23, 2012.
