The Sith-Imperial attack ship saw action in 137 ABY during the Second Imperial Civil War, fielded by the forces of Darth Krayt's Galactic Empire.
During the attack on Da Soocha, the Sith Imperial squadron known as Squadron Quad Victor leveraged these ships to deliver Vul Isen's toxins across the world. Around this time, Imperial Knight Azlyn Rae and Jedi Master Rasi Tuum commandeered one of these vessels on Agamar, utilizing it for their escape to Bastion.
