Star Destroyer

Everi Chalis stated that Star Destroyers represented the most resource-intensive vessels ever conceived in the galaxy. Only the Kuat system possessed the necessary shipyards to effectively support and maintain more than a select few at any given time.

The Executor-class Star Dreadnought, alternatively recognized as the Super-class Star Destroyer, represented the largest Star Destroyer configuration ever manufactured by the Galactic Empire. Commonly designated as a Super Star Destroyer, this class included the Executor I-class and Executor II-class sub-models. With a length of 19,000 meters, these vessels served as command ships and were equipped with over 5,000 turbolasers and ion cannons.

The Mega-class Star Dreadnought, also known as the Mega-class Star Destroyer, functioned as the capital ship of the First Order and its Supreme Leader. Measuring 13,000 meters in length and possessing a wingspan of 60,000 meters, the Mega-class exhibited a greater width than length. The Supremacy, the sole vessel of this type, was utilized by Supreme Leader Snoke and the First Order Navy during their attacks against the Resistance.

Throughout galactic history, various Star Destroyers were categorized as battlecruisers. The Maelstrom-class battle cruiser, which was used by the Galactic Republic during the Clone Wars, was mostly put into reserve by the Galactic Empire. However, at least one example, the Simoom, was operated by the Alliance to Restore the Republic. The Maelstrom-class was regarded as a proto-Star Destroyer, outfitted with assault concussion missile launchers, heavy cannons, and a variety of other armaments. Maelstroms were deployed in planetary sieges, orbital bombardment, fleet-command roles, and other operational capacities.

The Secutor-class Star Destroyer, also identified as the Secutor-class battlecarrier, represented another battlecruiser variant within the Star Destroyer design lineage. Spanning multiple kilometers in length, the Secutor served as both a carrier and command ship for the Galactic Empire. It may have been the largest starfighter-focused vessel within the Imperial Navy. The First Order, the Empire's successor, extensively employed the Resurgent-class Star Destroyer (also referred to as the Resurgent-class Battlecruiser) during the Cold War and the First Order-Resistance War. The Resurgent, a 2,915 meter-long warship, boasted sophisticated weaponry and advanced systems.

According to the Anaxes War College System, the Sith Eternal's Xyston-class Star Destroyer, measuring 2,406 meters, was classified as a battlecruiser. The Xyston was a Star Destroyer model based on an enlarged Imperial I-class design. The Xyston-class was equipped with substantial firepower, including the axial superlaser cannon capable of obliterating entire planets.

The Republic's Acclamator-class assault ship, a 752 meter-long cruiser, was considered a proto-Star Destroyer. Its sub-variants included the Acclamator I-class and the Acclamator II-class. It functioned as a carrier and transport for ferrying troops and vehicles to planetary surfaces. The Venator-class Star Destroyer, a cruiser class with a length of 1,137 meters, was also known as the Republic Attack Cruiser or Jedi cruiser and was regarded as a proto-Star Destroyer. It had two sub-variants, the Venator I-class and the Venator II-class, and it was used extensively by the Galactic Republic during the Clone Wars and by the early Galactic Empire.

The successor to the Venator-class, the 1,600 meter-long Imperial-class Star Destroyer, was also classified as a cruiser. The Imperial-class included the Imperial I-class, Imperial II-class, and the Interdictor-class sub-variants. The Imperial-class became iconic symbols of the Empire's New Order. The Interdictor-class heavy cruiser was a heavy cruiser class within the Star Destroyer family of ships used by the Empire. It measured 1,129 meters in length and was outfitted with four gravity well projectors to perform its Interdictor duties. The Onager-class Star Destroyer was also categorized as a cruiser class, and had a superweapon capable of destroying targets on a planet's surface or entire fleets.

According to the Anaxes War College System, the Gladiator-class Star Destroyer was another cruiser, and the smallest Star Destroyer in the Empire's arsenal at 600 meters long. Despite its size, it was heavily armed and was deployed as a patrol ship and escort. It could function as a flagship for small task forces or battle groups. The Gladiator I was a sub-variant of this class.

Beyond the cruisers, dreadnoughts, and battlecruisers, other Star Destroyer types were also in service. The Imperator-class Star Destroyer was a large, powerful, and versatile warship used by the Republic. The Imperator-class saw limited action, and were soon succeeded by the Imperial-class. The Empire also used the qaz-class Star Destroyer, equipped with multiple batteries. The Tector-class was another example that was in the Imperial Navy.

The Victory I-class Star Destroyer, deployed by the Republic and later the Empire, was another example of a Star Destroyer design. Its successor, the Victory II-class, was designed to address various design shortcomings.

During the Clone Wars, the Galactic Republic Navy operated a fleet of Venator-class Star Destroyers. The Venator-class participated in numerous engagements against the Confederacy navy, notably the Battle of Coruscant. Following the transformation of the Republic into the Galactic Empire, the Republic's Star Destroyers were integrated into the new Imperial Navy. In addition to the Venator and Imperial-class Star Destroyers, other known models in Imperial service included the Victory and Secutor-class Star Destroyers.

During the rebellion and the Galactic Civil War, Imperial Star Destroyers were involved in numerous battles against the various rebel groups that eventually formed the Alliance to Restore the Republic. Star Destroyers were deployed during the secret mission to Tatooine, Battle of Hoth, and the Battle of Endor.

After the events at Endor, the Rebel Alliance's successor government, the New Republic, captured and destroyed many Star Destroyers in various battles including the Battle of Theed, the Rebellion on Akiva, the Defense of Kuat, and the Liberation of Kashyyyk. By 5 ABY, Grand Admiral Rae Sloane estimated that 75% of the Imperial Star Destroyers before Endor had either been destroyed, captured, or lost in "confirmable if curious ways." While searching through the archives at the Hall of Imperial Register on Coruscant, Sloane discovered that the remaining 25% had mysteriously disappeared and their purported destruction had been falsified.

Sloane later learned that Fleet Admiral Gallius Rax secretly commanded Imperial fleets in the Almagest, the Recluse's Nebula, the Queluhan Nebula, the Ro-Loo Triangle, and the Inamorata. These fleets consisted of hundreds of Star Destroyers and thousands of smaller ships. Following the Attack on Chandrila, Rax ordered the Imperial fleets to assemble above the planet Jakku. During the Battle of Jakku, the cataclysmic battle that ended the Galactic Civil War in favor of the New Republic, numerous Star Destroyers, including Captain Ciena Ree's starship Inflictor, saw action.

Thirty years following the Battle of Endor, the wreckage of numerous Star Destroyers still littered the barren surface of Jakku. Scavengers, such as Rey, regularly targeted these abandoned starships. The First Order, a remnant of the Old Empire, was also known to utilize Star Destroyers as part of its fleet, such as the First Order's Resurgent-class Star Destroyers, which were inspired by the dagger-shaped design of the Old Empire's vessels. The First Order's leadership, including its Supreme Leader, were stationed aboard the gargantuan Mega-class Star Dreadnought Supremacy, the sole ship of its class.

When the revived Darth Sidious and his Sith Eternal cultists emerged from Exegol and assimilated the First Order's military after the death of Supreme Leader Snoke, the Sith Lord revealed his own armada, the Final Order, which consisted of 1,080 Xyston-class Star Destroyers. The entire fleet was destroyed in the Battle of Exegol before they could be deployed en masse.
