The Exactor-class attack frigate was a predecessor to the Acclamators used during the later parts of the Galactic Clone Wars, being constructed as a peacetime combat ship to guard the extensive shipyards in the Rothana system. They were designed to be very quick and maneuverable, with multiple engines, so that they could effectively patrol whole systems quickly and efficiently, with enough firepower to subdue most enemy vessels that may have approached the shipyards. However, the focus on speed and agility left the Exactor with relatively light shielding. The defensive capacity of the Exactor was further reduced by unarmored areas of the hull, exposed to space for various maintenance and cooling reasons.
