Super Star Destroyer/Legends

Super Star Destroyer "Concentrate all fire on that Super Star Destroyer!"

- Admiral Ackbar, referring to the Executor, during the Battle of Endor

Super Star Destroyer (SSD) was a term used by Imperial, Rebel, New Republic and Galactic Alliance personnel for many dagger-shaped warship classes larger than Star Destroyers, ranging from Star Cruiser to Star Dreadnought models. In extreme cases, they are also large enough to be qualified as space stations.

It was often used concurrently with the term Super-class Star Destroyer, both of which capitalized on the general "Star Destroyer" term, which, after getting popular exposure throughout the Clone Wars, came to symbolize weapons that in people's minds could destroy entire star systems.

Darth Vader's command ship, the Executor, was a Super Star Destroyer and one of the most famous Imperial vessels fielded, as was the even deadlier Eclipse, which served as one of Emperor Palpatine's flagships.

Characteristics


The term "Super Star Destroyer" was used to describe some of the largest warships ever designed and fielded and covered various warship classes that served primarily as command ships. All the known models were at least several kilometers in size in order to support their increasingly heavy power generators and armaments. In at least one ship classification system, SSDs were regarded as large enough to be counted as space stations rather than regular starships.

The largest known models were usually fitted with extensive command and control suites which could handle far more naval forces than previous command stations, such as the Old Republic's Republic command ships of the Krath Holy Crusade or the Inexpugnable-class tactical command ships of the Mandalorian Wars. Like most other starship production lines, different ships within the same class were often subject to different specifications in terms of armament, crew and support vessels, based on their intended focus and roles.

Super Star Destroyers were on par with or larger than most other navies' ships-of-the-line, like the Trade Federation's Lucrehulk-class battleships or the Subjugator-class heavy cruisers of the CIS. As command ships, SSDs like the Executor-class were capable of projecting power across entire Oversectors and served as command ships for galaxy-spanning campaigns. They were good expressions of the Tarkin Doctrine, which argued that galactic peace could be achieved by developing the ability to project overwhelming firepower against any enemy, rendering all resistance futile before it even began.

Star Cruisers
The smallest SSDs were designated as Star Cruisers. These were not to be confused with other Star Cruisers in existence, such as Rendili's line of hammer-headed cruisers, the contemporary Mon Calamari-produced line of warships or the common space transports and smaller warships found throughout the galaxy. This particular designation was for warships of a size and power eclipsing Star Destroyers, that were still a magnitude smaller than Star Battlecruisers and Star Dreadnoughts.

A typical Star Cruiser model was the Allegiance-class, designated a battlecruiser in the Anaxes War College System. This system was devised by Republic military educators during the Clone Wars, with battlecruisers and dreadnoughts making up the two largest scales of warship classes within its categories. Star Cruisers were considered by some to be a subset of this battlecruiser class and the Allegiance-class was a good example of what the Anaxes system considered the smallest battlecruisers.

Star Battlecruisers
Star Battlecruisers were among the most powerful vessels in the galaxy, with reactors capable of delivering enough power to weaponry that could down multiple Star Destroyer-scale vessels and to defensive shields that could resist an onslaught of even dreadnoughts.

The battlecruiser class of the Anaxes War College System roughly corresponded with the Star Battlecruiser designs, but covered other large military classes as well. Known models in the Anaxes system were between 2,000 and 5,000 meters in length and were built for long-range, independent missions. Typical Star Battlecruiser designs included the 2,500 meter Procurator and 4,000 meter Praetor-classes.

Dreadnoughts
Battlecruisers were only eclipsed in capability and size by dreadnoughts, of which the aforementioned Executor and Eclipse Star Dreadnoughts were among the most extreme designs, literal cityscapes fitted with gun batteries and shield generators.

In the Anaxes War College System, dreadnoughts were typically designs with lengths of 5,000 meters and beyond, though the mass, capability and volume of a shorter vessel could qualify it.

Logistical vessels
In addition to dedicated warships, there were also several support ship types built to SSD-scale. Some served as dedicated carrier vessels, others, like the battlecruiser Pride of Tarlandia, were communications ships and had dozens of HoloNet transceivers fitted to the design. A third group functioned as mobile repair ships.

Origin
"From Super Star Destroyers to torpedo spheres, it has been nearly impossible to overestimate the amount of destructive force available to the average Moff or Sector Group Commander"

- Arhul Hextrophon, on the Empire's obsession with super weapons.

For tens of thousands of years, heavy warships were part of the Republic Navy's strategy for space combat. Large ships fought in the Alsakan Conflicts and the Old Sith Wars. They became obsolete at some point after 3000 BBY, when fleet doctrine shifted to groups of smaller-scale cruisers that combined their firepower and were more maneuverable. These new designs were armed with better weapons and more powerful shields than the older battlecruisers and battleships.

However, by the centuries prior to the Clone Wars, heavy warships had gained prominence again. The first modern design that would be lumped into the Super Star Destroyer category was the Procurator-class Star Battlecruiser, built two centuries before the Clone Wars. It spawned a series of increasingly large warship designs and went on to have many different models in its own production line.

Large vessels like the Procurator were used for generations by private defensive fleets fielded by rich, industrialized star sectors. Kuat, Corellia and Humbarine were but three of the industrialized Core sectors that could afford to build such behemoths, which were fitted with hyperdrives with limited range to highlight their defensive purposes in the relatively peaceful period of the time.

While as a member of the Techno Union, the shipyards of Kuat began to experiment further in this period with warship-designs that eclipsed previous generations. Two decades prior to the Clone Wars, the shipyard unveiled the Mandator-class, a type of design that would fill out the modern dreadnought category in the Anaxes War College System.

During the Clone Wars, heavy warship classes like the Star Battlecruisers and Star Dreadnoughts were used by the resurgent Republic Navy, as large defense vessels. Some battlecruisers were refitted to lead task forces on raids deep into Separatist territory.

In the aftermath of the Wars, the newly created Galactic Empire began an unprecedented research and development program for a new generation of heavy warship designs,, creating vessels that would bear the colloquial term Super Star Destroyer.

Super Star Destroyer production was sometimes helped along by innovations in other areas. The Clone Wars saw the development of the Cardan-class space station series which came to have some influence on the structuring of future naval projects, including the Super Star Destroyers and the Death Star battlestations.

A few months after the end of the Clone Wars, the Sarlacc Project was begun. It sought to develop a new, heavy Imperial command ship. This vessel, an early prototype for a new generation of dreadnoughts, was 12 kilometers in length and meant to be filled with weapons. It was destroyed by early rebel elements before it could be completed. Despite such an early setback, larger and more refined Star Dreadnought designs were eventually produced, noticably the Executor-class and Eclipse-class.

The Executor-class became a highly sought after command ship and the creation of the lead vessel and other members of the class was mired by political intrigue and misinformation campaigns. When the Imperial Navy requested funds for construction of the Executor, it forged a profile on the vessel, calling it a Super-class Star Destroyer and making it out to be less than half its intended size, on par with the earlier Mandator- and Mandator II-classes. This was done to avoid arousing suspicion in the Imperial Senate about the true nature of the design as well as capitalize on the popularity of the dagger-shaped Star Destroyer class, which dated back to the Clone Wars.

The term was shortened to "Super Star Destroyer", and both it and the fake designation of Super-class, remained in colloquial use even long after the real name and designation had been revealed and the first vessel made operational.

As these vessels became a greater part of naval doctrine, some officers and military planners derided the battlecruisers and dreadnoughts as a wasteful budgetary expense. They derisively referred to all the designs as Super Star Destroyers and argued that vessels at Star Destroyer-scale and smaller were the only things needed to keep the Empire safe. With the advent and subsequent destruction of the first Death Star, the Navy reluctantly adopted SSDs as a viable and cheaper alternative. Due to their increased effectiveness as terror weapons, dreadnought production was prioritized over battlecruiser designs.

Battlecruisers like the Praetor-class survived the transition into the Galactic Empire, but continued in limited service during the Galactic Civil War. Battlecruisers were hampered by their relative inflexibility compared to Star Destroyers and the lack of heavier firepower compared to the dreadnought models. The Praetor-class, for one, was considered outright outdated.

"Super Star Destroyer" and "Super-class" later carried over to other warship designs in the following decades, with even the Rebel Alliance referring to anything bigger than a Star Destroyer by these terms. Beyond the colloquialisms, many SSDs were referred to as "star dreadnoughts" as well, contrasting the usage of "star cruiser" (lower-case) to refer to Star Destroyers.

Early Imperial production
Before the Battle of Yavin, most Super Star Destroyer dreadnought production lines were still undergoing construction, and the few partially constructed ships were only used as command centers. At least one Super Star Destroyer was also put in dry dock in the first Death Star some time before its destruction in 0 ABY.

Once the Empire realized the threat posed by an organized rebellion with the downfall of the first Death Star battlestation, the Super Star Destroyers began to be mass-produced, with an average Moff or Sector Group Commander estimated to have at least one or more such superweapons in their arsenal throughout the course of the Galactic Civil War, bringing the total amount of ships up to hundreds or even thousands. The Executor-class alone was believed to have been made with over 20 ships to its name, their combined bulk equating to that of thousands of individual Star Destroyers. Such heavy warships served both as sector as well as regional command centers with individual ships kept off the records as black projects, sent into the Unknown Regions for secret missions or stationed at hidden sites as additional assets.

In addition to mass-production, influential individuals could afford customized designs at the height of the Empire. The Dark Jedi and Inquisitor Jerec had Kuat Drive Yards build a grandiose flagship for himself, replacing his Imperial-class Star Destroyer as a sign of his growing ambitions. This vessel became the lead ship of its own class of dreadnoughts in addition to other dreadnought designs being produced during this period.

Overall, despite consisting of several classes with multiple models in each category, each Super Star Destroyer production line was relatively short, compared to the prolific Star Destroyers. There were still enough active ships around the time of the Battle of Hoth, to make Rebel personnel also refer to them by the general term of Super Star Destroyer. In addition, at some point after the development of the Executor line of Star Dreadnoughts, at least two similar vessel models, ranging between 8 kilometers and 12.8 kilometers, were developed.

While conventional armaments were designed for most ships, the two Eclipse-class dreadnoughts had a superlaser as their primary weapon. The bulk of these two Super-class Star Destroyers was built around each ship's reactor and support systems, making them the most powerful conventional warships in history, and causing the design to attract unwanted attention from criminal third parties.

Their construction took almost over a decade, with the Emperor's downfall leading to delays and shifts in logistics. They were estimated to be powerful enough to allow whoever controlled them a real chance at taking power in the galaxy. This also made them high-profile targets by both the Rebel Alliance, and later, the New Republic. As a symbol of its status, the Eclipse was escorted by smaller Super Star Destroyers during the Battle of Pinnacle Base.

After Endor
Following the collapse as a result of the Battle of Endor, it became increasingly difficult to maintain gargantuan warships, with the gradual breakdown and fracture of the Galactic Empire. Despite dozens of active battle groups being led by SSDs immediately after Endor, the lack of cooperation between various parts of the Empire and the gradual rise to power of the New Republic, led to many Super Star Destroyers being destroyed or captured outright.

The focus switched to Star Destroyers or smaller vessels for the various Imperial warlords. Former support ships like the Strike-class medium cruiser saw a renewed service period as more mainline warships in the fleets of the Imperial Remnant.

The last major SSD known to have been commissioned by legitimate Imperial forces, was an Executor-class ship known as the Razor's Kiss. It was, however, destroyed by the New Republic soon after her launch from Kuat in 7.5 ABY.

With the years passing, the number of Super Star Destroyers dwindled as the older ships left in service were either destroyed, captured or kept in isolated Imperial enclaves. By the time Grand Admiral Thrawn took command of the Empire five years after Endor, his naval forces could not gain access to anything bigger than individual Star Destroyers. Even warlords who kept diplomatic relations with Thrawn, were hesitant to throw their dreadnoughts in with his forces.

Concurrent with the warlordism, some fleet elements were recalled to the Deep Core, where scores of heavy warships became part of the "Dark Empire" ruled over by the clones of Palpatine. Here, the resurrected Emperor plotted their use as tools of conquest for 6 years after Endor, unleashing them alongside his fleets of World Devastators during the attempt at regaining his former glory with Operation Shadow Hand in 10 and 11 ABY.

Prior to this operation, this Dark Empire retook large portions of the Core Worlds, beginning a vicious Imperial Civil War in the aftermath of the retaking of Coruscant from the New Republic. Several prominent Super Star Destroyers were destroyed in the infighting, like the Mandator III-class dreadnoughts Aculeus and Panthac and the Executor-class dreadnought Whelm.

During the rise of the resurrected Palpatine, at least four 15 kilometer-long Sovereign-class Star Dreadnoughts underwent construction, while the two Eclipse-class vessels were completed and fielded. These six vessels were meant to be the beginning of a new era of superlaser-armed warships, but with the destruction of Byss and the final death of the Emperor, they were all destroyed.

The power having shifted to the New Republic, the threat of SSDs decreased. Despite this, the Republic constructed a counterpart to the Empire's Super Star Destroyers, with the Mon Calamari-produced Viscount-class Star Defender and Mediator-class battle cruiser filling out holes in the Republic's naval forces.

Apart from the Republic's new designs, several SSDs remained in the hands of foreign powers. One 8 kilometer long SSD was observed in the fleet of the Imperial Remnant during the Yuuzhan Vong invasion and at least one Executor was part of rogue Imperial pirate forces just prior to the start of this conflict.

Further service


During the events surrounding the Swarm War, the Megador, a Super Star Destroyer equipped with sixteen engines, was used as flagship for the then-supreme commander of the Galactic Alliance Defense Force, Gilad Pellaeon.

During both the Yuuzhan Vong invasion and the Swarm War, some of the alien warships were compared with some type of 8km long Super Star Destroyer. It is unknown if this referred to the ships of old, or vessels in current service with the New Republic.

Super Star Destroyers were known to be used in the Second Galactic Civil War, with the Megador and the Dominion participating on the side of Darth Caedus's faction of the Galactic Alliance. At some point following the Second Galactic Civil War, heavy warships like the Star Defenders and Star Dreadnoughts were phased out of service, citing the expenses in operating the various designs.

Legacy
By 130 ABY, the main-line Pellaeon-class Star Destroyer had some of its systems partially based on achievements made with the successful Executor-class. The larger Imperious-class Star Destroyer was based on the Pellaeon and had a larger frame than the standard Star Destroyer classes of previous generations, but still shared their designation rather than be rated a battlecruiser or a dreadnought.

The Aramadia
The Aramadia was an Imperial SSD that was captured by the Yevethans and acted as one of Nil Spaar's flagships during the Yevethan Purge in 16-17 ABY. Following the Battle of N'zoth and the end of the Purge, it was towed to N'zoth and used as a museum. In top-down profile, it resembled the Imperial-class Star Destroyer.

The Arc Hammer
At least 9.6km long, almost half as long as an Executor-class Star Dreadnought, the Arc Hammer was essentially an armed factory ship that also served as a command ship for the Dark Trooper Project. The design was very sleek compared to other Super Star Destroyers (similar only to Jerec's ship), and noteworthy for a large quadruple tower structure protruding from the dorsal and ventral side in the general area of the bridge structure. Dorsal bays could launch the ship's complement of Dark troopers onto a target in a combat drop. The Arc Hammer was destroyed from within by Kyle Katarn's sabotage.

Assertor-class Star Dreadnought
The Assertor-class Star Dreadnought was a heavily armed Imperial Star Dreadnought. Ships of this class sometimes led elite units that used TIE/D Defender starfighter squadrons. Two were seen at Naval Station Validusia.

The Wrath
The Wrath was an Assertor-class Star Dreadnought that led a Base Delta Zero operation at one point.

The Aurora
The Aurora was a dreadnought used to defend Kuat against the New Republic in 8 ABY. During the Taking of Kuat, it was taken by the Republic, but launched into the sun soon after when Imperial saboteurs activated its hyperdrive.

Bellator-class dreadnought
The Bellator-class dreadnought was based on the earlier Mandator and Mandator II dreadnought models and was a slightly scaled down version of them. Several vessels were seen at Naval Station Validusia. Two Bellators were viewed by the commanders of Death Squadron at a fleet gathering prior to the Battle of Hoth. At least one vessel later served in the forces of the resurrected Emperor Palpatine in 10 ABY. A Bellator was escorted by a Star Destroyer in orbit of Byss around this time.

The Dominion
The Dominion was a Super Star Destroyer that served in the Imperial Remnant around 41 ABY. It participated in the First Battle of Roche and was defeated by a fleet of starfighters.

Eclipse-class dreadnaught
The Eclipse-class was designed as flagships for Emperor Palpatine and were constructed in relative secrecy. They were 17.5 kilometers in length, with much of their interiors taken up by generators, used to power the ship's main weapon, a scaled-down superlaser. The class's design was meant to invoke ancient sea-going warships.

The Eclipse
The Eclipse was the lead ship of its class. It took almost 10 years to finish, with its construction beginning around the time of the Battle of Yavin in 0 BBY. It was hijacked by Zann Consortium forces during the Battle for the Eclipse in 4 ABY and later recovered. Construction was moved to Byss, where it stayed in orbit for years, serving as a space station and meeting ground for various groups. When finally commissioned during the return of Emperor Palpatine, it gained some notority with New Republic personnel, thanks to its devastating superlaser. The Eclipse was lost above Pinnacle Base in 10 ABY, a victim of Palpatine's runaway Force powers.

The Eclipse II
The Eclipse II was built in parallel with the Eclipse and served as Palpatine's flagship after the loss of the first vessel. It fought in the Battle of Onderon in 11 ABY, was hijacked by a New Republic task force, and sent to the Beshqek system. Here, it crashed into the Galaxy Gun orbiting Byss, and was lost when the planet exploded.

The Event Horizon
The Event Horizon was a battlecruiser used to defend Kuat against the New Republic in 8 ABY. It was captured by the Republic, when a previously inserted computer virus forced the battlecruiser and four Star Destroyers to lock down their hangars and target the remaining Imperial fleet.

Executor-class Star Dreadnought
The Executor-class Star Dreadnought was the first class associated with the SSD moniker. It was 19 kilometers in length, was powered by a central reactor underneath its command tower, had over 5,000 various weapons-systems, and could carry over a thousand starfighters in its multiple hangar bays. Its design was meant to overwhelm any opposition, sending the enemy into retreat or resignation by its mere presence. The class became popular within the Imperial Navy, and officers desired such ships as a status symbol. Since the Super-class designation originated with this ship, it was often called Super-class Star Destroyer interchangably with other terms.

The Aggressor
An Executor-class Star Dreadnought that patrolled the Inner Rim, before being appropriated by Grand Admiral Josef Grunger for use as his flagship shortly after the Battle of Endor in 4 ABY. Destroyed at the Battle of Tralus in 6 ABY.

The Annihilator
Flagship of Admiral Gaarn. Destroyed during the Battle for the Eclipse in 4 ABY.

The Enforcer
Commanded by Admiral Kohrin and fought a Rebel fleet near Bespin. It was damaged and sent to Phaylenn for repairs, but was ambushed while in drydock and destroyed.

The Executor
Lead ship of its class and Darth Vader's flagship. Served as Vader's private headquarters for years until its completion six months after the Battle of Yavin, in 0.5 ABY. Participated in many battles before crashing into the Second Death Star at the Battle of Endor in 4 ABY.

The Guardian
Originally served in the home fleet of Imperial Center under Fleet Admiral Gaen Drommel. After Endor, he took the ship to Oplovis and became a warlord. After a New Republic task force captured it, the Guardian became part of the New Republic Third Fleet and served with the Republic and the Galactic Alliance for decades.

The Intimidator
Built for Black Sword Command, it was captured by the Yevetha during their uprising in 5 ABY. The Intimidator became one of their flagships, but was recaptured by Imperial slaves using its slave circuit, at the Battle of N'zoth in 17 ABY. Years after their escape, it was found adrift in the Unknown Regions in 21 ABY, a derelict hulk.

The Iron Fist
Originally named the Brawl, it was one of the first Executor-class vessels and was given to Zsinj upon his promotion to Admiral. He later used it in his campaigns against the New Republic as a warlord. The Iron Fist was finally destroyed over Dathomir in 8 ABY.

The Knight Hammer
The Knight Hammer, formerly Night Hammer, was an Executor-class Star Dreadnaught equipped with black stealth armor and a slave circuit. It was built in secret by Imperial warlord Delvardus and used by Admiral Natasi Daala in an assault on the Jedi Praxeum in 12 ABY, where it was sabotaged and destroyed.

The Lusankya
Originally named the Executor II, the Lusankya was built in secret by KDY and contained less heavy batteries, substituted for more point-defense guns and an increased amount of automation. It was buried underneath the surface of Imperial Center after its commissioning. For years it stayed underground, acting as a prison facility, until 6 ABY, when it was used by Ysanne Isard as an escape vehicle and later command ship in the Bacta War. The vessel was captured by the New Republic and served in its navy until the Second Battle of Borleias during the Yuuzhan Vong War, where it was used as a giant projectile and destroyed.

The Razor's Kiss
Built at Kuat Drive Yards, the Razor's Kiss was destroyed by the New Republic before it could be taken by warlord Zsinj. He later used the remaining debris in a ruse to make it appear that his command ship, the Iron Fist, was destroyed in battle in 8 ABY. The remains were collected and assembled into the Second Death for this purpose.

The Reaper
The Reaper was the flagship of Grand Moff Ardus Kaine. He used it as a command ship for his Scourge Squadron, hunting Rebel groups in the Outer Rim Territories. After Endor, Kaine struck out as a warlord and used the Reaper as the meeting place where the Pentastar Talks were held. It later fought in Operation Shadow Hand, where Kaine lost his life. It was then used as a command ship by Admiral Gilad Pellaeon of the Imperial Remnant and ultimately fell during Pellaeon's successful counterattack against a New Republic invasion force.

The Second Death
This vessel was assembled from the remains of the Razor's Kiss and used as a substitute for the Iron Fist, making it appear that the vessel had been destroyed. As such, it had no shields or weapons, but was fitted with a nightcloak to make it appear invisible until needed in battle.

The Terror
The Terror was the flagship of Admiral Sarn. It was fitted with a stygium cloaking device, and used as a carrier for the first squadrons of TIE Phantom starfighters. It was meant to spearhead renewed assaults on the Rebel Alliance, but was destroyed over Imdaar Alpha in 3 ABY.

The Vengeance
This Vengeance was an Executor-class ship that served as Admiral Wooyou Senn's command vessel. It led Task Force Vengeance in an attempt to quell a Rebel expansion in the Airam sector and was believed destroyed at the Battle of Nocto.

The Whelm
The Whelm was an Executor-class Star Dreadnought that served as part of Azure Hammer Command in the Core. It disappeared when the New Republic sought to engage it during their de-Imperialization campaign in the Core Worlds and later resurfaced to participate in the prelude to Operation Shadow Hand. The ship was lost during the resulting civil war, in a duel with a rival faction's dreadnought, the Panthac. The two dreadnoughts destroyed one another in the firefight.

The Ilthmar's Fist
The Ilthmar's Fist was a battlecruiser that served in the Imperial Navy and participated in the Battle of Endor. It survived the battle and was later taken to the Deep Core by Admiral Blitzer Harrsk.

Imperial communications ship
The communications ship was a type of SSD used to communicate and coordinate the actions of other warships. To facilitate this, each vessel was fitted with dozens of hyperspace transceivers.

Imperial Star Battlecruiser
While older classes like the Praetor were gradually shifted out of service, newer battlecruiser lines were produced by KDY during the Galactic Civil War.

Imperial Star Cruiser
During the height of the Galactic Civil War, Rebel personnel had begun to refer to several large warship types colloquially as "Super Star Destroyers", a type of Star Cruiser being one of them. This subclass of large battlecruiser designs was a rare sight in the Imperial military, as naval strategy focused more on Star Destroyers and the larger dreadnought classes.

Allegiance-class battlecruiser
The Allegiance-class design was a typical example of the Star Cruiser subclass of battlecruisers. Allegiances were smaller Super Star Destroyers seen in use as escorts for larger vessels like the Eclipse-class. They had a design reminiscent of the Imperial-class Star Destroyer, only larger. The class had a ventrally protruding reactor core and no visible launch bay.

The Allegiance
The Allegiance was an Allegiance-class SSD that acted as a communications vessel at the Battle of Mon Calamari during Operation Shadow Hand.

The Luminous
The Luminous was a battlecruiser used to defend Kuat against the New Republic in 8 ABY. It was captured by the Republic, when RZ-1 A-wing interceptors overloaded its systems with ion torpedoes.

Mandator I-class Star Dreadnaught
The Mandator I-class Star Dreadnaught was built by KDY prior to the Clone Wars. The Mandator I-class provided protection for the Kuat sector prior to the Clone Wars, and served as a show-piece for the rich sectors of the Core. Eventually, seven were built for the protection of those sectors that could afford them. During the Wars, three of the ships were upgraded to Mandator II specifications.

The Mandator
The Mandator was the lead ship of the Mandator I-class. It was built two decades before the Clone Wars and meant to be the centerpiece of the Kuat sectorial fleet as well as a demonstration to potential buyers in the Core.

Mandator II-class Star Dreadnaught
The Mandator II-class Star Dreadnaught was built and fielded by KDY and the Galactic Republic. The model served in the Republic Navy during the Clone Wars and guarded vital targets from Separatist attacks.

Mandator III-class dreadnought
The Mandator III-class was built and fielded by the Galactic Empire. It was several kilometers longer than previous models and enlarged to carry massive armaments.

The Aculeus
The Aculeus was a Mandator III that participated in the prelude to Operation Shadow Hand. It was destroyed during the Imperial Civil War by swarms of TIE/D automated starfighters used by a rival faction.

The Panthac
The Panthac was a Mandator III that participated along with the Aculeus in the reconquest of the Core. It was later destroyed in a duel with the Executor-class dreadnought Whelm during the Imperial Civil War when each commander decided to follow a different faction.

The Megador
The Megador was a sixteen-engined SSD that served in the Galactic Federation of Free Alliances. It was armed with long-range turbolasers during the Second Galactic Civil War.

Mobile repair base
The mobile repair base was a type of SSD dedicated to repairing and servicing other warships. As such it did not serve as command ships, which was typical for Super Star Destroyers.

Praetor-class Star Battlecruiser
The Praetor-class Star Battlecruiser was a heavy warship equipped with powerful reactor-systems. They were produced during the time of the Galactic Republic, but were gradually replaced in the Galactic Empire. Despite this, some of the outdated ships were still in service during the Galactic Civil War. The Rebel Alliance stole reactor equipment from a derelict Imperial Praetor and used them to power its defenses at the Battle of Hoth, holding off several Star Destroyers as well as Darth Vader's flagship, the Executor.

The Quaestor
The Quaestor was a Republic Praetor-class Star Battlecruiser that destroyed the Separatist Pammant Docks in a hyperspace accident, which sent the ship plunging into Pammant itself, shattering the world to its core and flooding the planet with radiation.

Praetor II-class Star Battlecruiser
The Praetor II-class Star Battlecruiser was the Imperial successor to the Republic Praetor-class Star Battlecruiser. It had a bridge tower that extended towards the stern of the vessel.

The Helmsman
The Helmsman was a Praetor II-class Star Battlecruiser commanded by Admiral Mils Giel. At the stern of the vessel, it was fitted with a massive holding cage to be able to transport a Teezl creature across the galaxy. The Empire wanted to use this being as an instant communications device at Imperial Center. Despite being damaged in an attack by Rebel fighters, the vessel continued to function and even attempted to down enemy fighters.

The Thalassa
The Thalassa was a Praetor II-class Star Battlecruiser commanded by Admiral Sander Delvardus.

The Pride of Tarlandia
The Pride of Tarlandia was a battlecruiser that served in the Imperial Navy and participated in the Battle of Endor. It was the main communications ship on the Imperial side and was damaged in a duel with a Rebel cruiser, then destroyed in an attack by Rebel fighters led by the Millennium Falcon.

Sovereign-class dreadnought
The Sovereign-class was a 15 kilometer long, scaled-down version of the Eclipse-class, meant for mass-production. Like the Eclipse, the Sovereign was armed with a superlaser as its primary weapon. None of the four initial ships survived the fall of the resurrected Palpatine, and were destroyed before completion.

The Autarch
One of the first four Sovereign-class ships under construction at the time of Operation Shadow Hand. Destroyed when Palpatine's resurrected Empire collapsed.

The Despot
One of the first four Sovereign-class ships under construction at the time of Operation Shadow Hand. Destroyed when Palpatine's resurrected Empire collapsed.

The Heresiarch
One of the first four Sovereign-class ships under construction at the time of Operation Shadow Hand. Destroyed when Palpatine's resurrected Empire collapsed.

The Sovereign
Lead ship of the Sovereign-class. Destroyed when Palpatine's resurrected Empire collapsed.

Starfighter carrier
The starfighter carrier was a type of SSD primarily used as a carrier vessel.

The Stellar Halo
The Stellar Halo was a battlecruiser used to defend Kuat against the New Republic in 8 ABY. It was captured by the Republic, but soon after launched into the sun after Imperial saboteurs activated its hyperdrive.

Super Star Destroyer (12.8km)
This SSD class was 12.8 kilometers long and built at some point during the Imperial period.

Super Star Destroyer (8km)
This type of SSD, referred to as Super-class Star Destroyer, was referenced during the Yuuzhan Vong War and Swarm War in comparison to Yuuzhan Vong and Killik warships.

Super Star Destroyer (Bastion)
A Super Star Destroyer 8 kilometers long served in the Imperial Remnant during the Yuuzhan Vong invasion, where it was stationed at Bastion.

Super Star Destroyer (Black Sword Command)
This vessel was one of three SSDs known to be part of the naval forces of Black Sword Command, at some point around the Battle of Endor in 4 ABY.

Super Star Destroyer (Death Star)
This vessel was seen undergoing construction or repairs onboard one of the Death Star battlestations. The Sith Lord Darth Vader was present at the time.

Super Star Destroyer (Isard)
This vessel, under the control of Ysanne Isard, was used to bring the Imperial scientist Evir Derricote from Borleias to Coruscant in 6 ABY.

Super Star Destroyer prototype
This ship, developed in the Sarlacc Project, was 12 kilometers long, had a central reactor and was meant to be covered in armaments and serve as the Imperial Navy's symbolic flagship. It was destroyed while partially unfinished during the Battle of Byss. Despite its destruction, it served as a precursor to later classes, like the Executor.

Vengeance-class dreadnought
This dreadnought model was used by the Galactic Empire. Several vessels participated in the prelude to Operation Shadow Hand, where at least one was destroyed during the infighting of the Imperial Civil War.

The Javelin
The Javelin participated in the reconquest of the Core Worlds from the New Republic. It was later destroyed in a duel with a rival Imperial faction's Torpedo Sphere during the internal civil war in 10 ABY.

The Vengeance
This Vengeance was a KDY Super Star Destroyer built to the specifications of the Dark Jedi Jerec. It served as his command ship and had similar specifications to other Super Star Destroyers, apart from being visually distinct. It became the lead vessel of the Vengeance-class. The vessel was thinner and less wide than the Executor-class, with a smaller command tower and had a different set of engines.
