The Assertor-class Star Dreadnought, also known as the Assertor-class Command Dreadnought and the Assertor-class dreadnought, was a class of Star Dreadnought manufactured by Kuat Drive Yards that served in the Galactic Empire. One of the largest vessels in the Imperial Navy in terms of size and power, it was characterized by its long and thin arrow-shaped hull. The dreadnought boasted a large array of armaments and utilities to fulfill its roles as a command ship, sector patrol vessel, and fleet operations craft.

The Assertor-class dreadnought saw use in the Imperial Era during the time of the Rebel Alliance, with the lead ship of the class, the Assertor, and its sister ship, the Wrath, being introduced prior to the Battle of Yavin. During the Galactic Civil War, both ships and their battle groups conducted anti-Alliance operations along the border between the Mid Rim and the Outer Rim Territories.

The Assertor was deployed by the naval forces of the Galactic Empire and saw service during the Imperial Era. The lead ship of the class, the Assertor, and its sister ship, the Wrath, were laid down at Kuat Drive Yards at some point prior to the Battle of Yavin in 0 BBY. During the Galactic Civil War, the Assertor was deployed with its battle group, along with the Wrath in another fleet. Both battle groups operated concurrently on the border between the Mid Rim and the Outer Rim Territories to provide support for anti–Rebel Alliance operations.

Although the exact composition of the battle groups was not known, it was assumed that both vessels operated with dozens of other ships including smaller dreadnoughts, Imperial I-class and Imperial II-class Star Destroyers, numerous cruiser-sized vessels, and numerous support ships. The fleet of an Assertor-class vessel at one point consisted of at least two Imperial II-class Star Destroyers and large scores of TIE/ln fighters, and was located near a light blue celestial body that was in proximity to a smaller, darker-colored terrestrial body.

At one point during the Empire’s reign, an agent of the Rebel Alliance was held captive aboard an Assertor, awaiting interrogation. In order to preserve Alliance secrets, the agent had to be eliminated or rescued.
