Assertor - class Star Dreadnought The Assertor " - class Star Dreadnought , also known as the Assertor " - class Command Dreadnought and " Assertor " - class dreadnought , was a class of Imperial Star Dreadnought . The " Wrath " belonged to this class . Description . Dimensions . The " Assertor " - class Star Dreadnought was 15 kilometers long and had a hull - shape similar to the " Executor " - class Star Dreadnought , being primarily shaped like an arrowhead . It was considered the second largest of the standard Star Dreadnought line ( with only the " Executor " - class being larger ) , as well as the largest in the Imperial Navy in a family that included the " Mandator " - and " Bellator " - class ships . The overall ship ' s hull was shaped like a long , thin arrowhead hull . On the top of the ship was a large , prominent ridge from the stern up to a few yards from the bow , containing several guns as well as the command bridge , slightly similar in appearance to the ridge of the " Mandator " - and " Bellator " - class dreadnoughts . On the ventral side of the " Assertor " were located three ridges — one directly behind the reactor bulge and two to the sides facing the ship ' s bow . Offensive and defensive systems . The class was equipped with a large amount of gun batteries mounted along the ridge of the ship , as well as the flat dorsal and ventral surfaces . Many of the batteries were positioned in patterned clusters . Its armament of turbolasers , while weak in comparison to the " Executor " - class Star Dreadnoughts , was nonetheless powerful enough to nearly vaporize a planet , and was also the second - most powerful dreadnought in the navy . Propulsion systems . The " Assertor " - class was designed with 28 aft thrusters for propulsion and a hyperdrive for interstellar - range travel . The main reactor jutted from the ventral side of the ship and was covered with armor plating , similar to the SFS I - a2b solar ionization reactor . Bridge tower . The " Assertor " < nowiki > < / nowiki > ' s T - shaped bridge tower was similar in appearance to many other Star Destroyer and Super Star Destroyer designs built during the Imperial Period . Because the " Assertor " was designed primarily for conventional fleet operations and Sector Command duties , the ship class is dotted with various sophisticated communications and sensor suites , and was also equipped with various command and control systems that allow its Commander a nearly unparalleled view of the battlefield . History . The " Assertor " - class served the Galactic Empire during the Galactic Civil War as a command ship and a heavily armed weapons platform . In addition to this , it frequently acted as a sector command and control ship , and when in fleet formation was often flanked by dreadnoughts of the " Mandator " and " Bellator " class . At least two were built prior to the Battle of Yavin , the lead ship " Assertor " , and the " Wrath " . By the time of the Battle of Hoth , both the " Assertor " and the " Wrath " were deployed with large battle groups to provide support to anti - Rebel operations along the border between the Outer Rim and Mid Rim territories . These battlegroups were rumored to be composed of dozens of other ships , including various smaller dreadnoughts , cruiser - sized vessels , numerous vessels , and " Imperial I " - and " Imperial II " - class vessels . Two " Assertor " - class ships were at one point serviced and refueled at Naval Station " Validusia " in the Validusia system . During a fleet exercise at some point after the Arms Race campaign , a ship of this class was refueled by an " Altor " - class replenishment ship , simultaneously with an " Allegiance " - class battlecruiser . The " Wrath " led at least one Base Delta Zero operation in its career . This dreadnought was in charge of a fleet consisting of " Imperial I " - and " Imperial II " - class Star Destroyers and at least one " Interdictor " - class Star Destroyer . The fleet also had access to squadrons of TIE / D Defender starfighters . Behind the scenes . The " Assertor " - class Star Dreadnought originated as a fanon design by Ansel Hsiao , envisioned as a 15 kilometer long warship with power generation approximately equivalent to 400 " Imperial " - class Star Destroyers . In addition , it was also the largest 3D modelling project he had done at the time , requiring 30 + million polygons . He based the design on a real - life antecedent : in the early 1900s , Senator , tired of the U . S . Navy ' s practice of annually requesting slightly bigger battleships , simply told them to design " " , the largest battleships possible that were only limited by their ability to cross the . The artist envisioned it as a more practical dreadnought design meant to combat the New Republic . The design entered continuity when it appeared in " The Essential Guide to Warfare " , on which Ansel worked as an illustrator . Jason Fry , author of " The Essential Guide to Warfare " , confirmed that the length and classification of the " Assertor " - class were recorded in official continuity in his blog , but stated on the forums at TheForce . net that any power calculations or other info not mentioned in the endnotes were not necessarily canon . The " " , when discussing the Super Star Destroyers , erroneously depicted the " Executor " as an " Assertor " - class instead of the " Executor " - class .
