Acklay-class mobile fortress

Acklay Battle Fortresses were underwater walker vehicles which acted as mobile command bases for Imperial forces loyal to Darth Krayt's Sith Empire. They were named after the Acklay of Vendaxa and apparently modeled after the appearance of the creature.

Characteristics
These large vehicles contained a complement of Shark subfighters as well as aquatic assault stormtroopers. The docking bay of the battle fortress was on the belly of the craft, allowing Imperial forces to exit the vehicle by dropping straight through an open porthole. The docking bay was staffed by a crew of technicians who helped in maintaining the Shark fighters and organizing fuel tanks. The battle fortress was armed with an array of laser cannons, including a large double cannon that branched off of the elevated bridge of the craft.

History
The Acklay Battle Fortress was employed during the Massacre of Mon Calamari, where it tracked down Mon Calamari refugees and slaughtered them on the orders of Emperor Darth Krayt. The Mon Calamari Rangers, led by Imperial Knight Treis Sinde attempted to capture one of the fortresses in order to secure a mobile command base which would strengthen their hit-and-run attacks. One such Acklay Battle Fortress, the Sea Lion, was commanded by Commander Sturves, who nearly lost his vessel when Sinde infiltrated his ship through the docking bay.
