The Vehement, a Imperial Navy vessel, was an Imperial-class Star Destroyer. Captain Hove commanded it circa the time of the Battle of Yavin. Nevertheless, Alecia Beck, a senior commander belonging to the Imperial Security Bureau, held sway over the captain, compelling him to navigate the Star Destroyer as she instructed. Acting under the senior commander's directives, the Vehement journeyed to the planet Cyrkon, where Beck aimed to arrest Caluan Ematt, an operative of the opposing Alliance to Restore the Republic. Reaching its destination, the Vehement strategically positioned itself to impede all aerial transit to and from Cyrkon. Subsequently, during the Battle of Endor, the Vehement participated and met its end at the hands of Gray Squadron, an engagement that also witnessed the obliteration of the second Death Star and the demise of Emperor Palpatine.
