Unidentified Star Destroyer

At some point by 1 BBY, the Galactic Empire used a Star Destroyer during a mission on the moon Jedha. An Imperial spy traveled to the moon's surface in order to retrieve a crate of kyber crystals from a crash-landed Imperial shuttle, while Imperial Command monitored the mission from aboard the orbiting Star Destroyer. During the mission, the spy communicated with the starship in order to update their superiors on their progress. Ultimately, the Imperials aboard the Star Destroyer arranged for a combat assault tank to be dispatched as reinforcements in order to allow for the retrieval of the crystals from a mercenary stronghold.
