Communications Ships serve as communication & coordination units in Imperial] fleet operations, as well as having extensive jamming capabilities.

One of these ships were present during the Battle of Endor, where it was found to be the source of the scanner-jamming that made the Alliance ships incapable of determining whether the Death Star IIs shield was up or down.

After a rough battle with a Mon Calamari Cruiser the Comm ship´s shields were weakened enough to allow for an extensive starfighter-strike. The ship was destroyed, which greatly hampered the operations of the rest of the fleet.

Originally meant to have a more prominent role in the film Return of the Jedi, the Comm ship´s model was never completed and only one of it´s scenes were used in the actual film. The scene only showed it´s massive command tower, which featured one main bridge and at least four distinct auxillary bridges, made for the purpose of easing it´s communication/coordination tasks.

The ROTJ novelization mentions the ship as being one of the biggest in the Endor fleet, thus it has been provisionally labeled as being a 'Star Cruiser'.
