Similar in appearance to contemporary Mandalorian Kyramud-type battleships, as they were both based on Basilisk technology, the assault ships were propelled by five engines and were armed with five medium double turbolasers, three heavy ion cannons and six super-heavy concussion missile launchers. These assault ships always had their guns charged and ready to fire, even when in hyperspace, which allowed them to engage moments after arriving on the scene of battle. They lacked landing bays, and instead had special airlocks permitting the easy projection of troops toward a ship to be boarded.
Ships of this kind participated in the Battle of Vanquo, and later on, in the bombing of Serroco during the Battle of Serroco. After a lengthy chase Neo-Crusader Shock Troopers from a Jehavey'ir-type assault ship took the Republic flagship Courageous.
