In April 2014, most of the licensed
Star Wars novels, games, and comics produced since 1976 (and prior to 2014), were rebranded by
Lucasfilm as
Star Wars Legends; and therefore declared non-canon to the franchise. Star Destroyers feature in numerous
Legends publications, with a considerable amount of additional notable information. According to
West End Games'
Star Wars: The Roleplaying Game sourcebooks and other texts,
Imperial-class Star Destroyers are constructed by Kuat Drive Yards and hold a distinguished place in the
Imperial Navy, symbolizing the Empire's military might with a peak number of more than 25,000 vessels. Like the
Venator and
Victory-class ships that precede it, the
Imperial-class is a
multi-role capital ship combining the roles of a
battleship,
starfighter carrier, and
troopship. Notable for its massive size and overwhelming firepower compared to its fore-bearers; a single
Imperial-class ship is capable of singlehandedly taking on a fleet of enemy vessels or "reducing the surface of a planet to a slag" (known as "Base Delta Zero"), and its mere presence is often enough to deter rebellion. Although the New Republic eventually upgrades its starfleet with newer ship types, the
Imperial-class Star Destroyer remains in service well into the
New Jedi Order era and fights during the
Yuuzhan Vong War. Described in
A Guide to the Star Wars Universe (1984) as being long,
Executor-class Super Star Destroyers were later described as being long. In addition to Vader's command ship
Executor,
Star Wars novels introduce the prison ship
Lusankya and stealth-armored
Knight Hammer as other in the class. The
Forces of Corruption expansion pack to the game
Star Wars: Empire at War introduced the
Aggressor-class Star Destroyer. Its plans were kept aboard the first Death Star, where they were studied along with other ship designs. Following the Battle of Yavin, the Zann Consortium stole the designs stored in a data pod amidst the wreckage of the battle station, as well as a prototype that Tyber Zann took as his flagship and christened the
Merciless, which was heavily modified over three years before being unveiled over Carida. The
Aggressor-class featured a bridge and shield generators similar to the
Imperial-class, as well as two fire-linked cannons fixed on its forward hull that fired an ion blast that disabled shields, followed by a plasma blast for maximum damage. The description "Star Destroyer" and "Super Star Destroyer" are applied to several another massive dagger/triangle-shaped warships in
Star Wars, such as the
Pellaeon-class Star Destroyer in the
Legacy comic series (2006–2010), and the reborn Emperor Palpatine's flagships
Eclipse and
Eclipse II Super Star Destroyers in the
Dark Empire series (1991–1995). The
Eclipse-class was perhaps the ultimate Super Star Destroyer or Star Dreadnought in the Expanded Universe, incorporating a Death Star-type superlaser but miniaturized and more advanced, and gravity well projectors to prevent enemies from jumping to hyperspace, and having strong enough shields/armor to be able to ram enemy vessels. Curtis Saxton, in the unofficial
Star Wars Technical Commentaries (he has since been the author of the official
Star Wars: Attack of the Clones Incredible Cross-Sections and
Star Wars: Revenge of the Sith Incredible Cross-Sections), has advocated using the term
Imperator-class in lieu of
Imperial-class. Saxton argues that "Imperial Star Destroyer" is a somewhat generic term, as the vast majority of Star Destroyer types are operated by the Galactic Empire's Imperial Navy which technically means they are all "Imperial Star Destroyers", although the
Imperator/
Imperial-class Star Destroyers are by far the most common type. Similarly, the "Super Star Destroyer" moniker has been used for numerous unrelated vessels of varying sizes and classes, so fans have suggested labeling the class instead of by the lead ship such as
Executor-class and
Eclipse-class, with some referring to them instead as a "Star Dreadnought" (sometimes spelled "Star Dreadnaught") to emphasize their massive size relative to Star Destroyers. Author
Jason Fry introduced the "Anaxes War College System" which specifically divide warships into different types depending on their size and power, which explain all the differently sized "Super Star Destroyers" appearing in the Expanded Universe (now
Star Wars Legends), supplementing the contradictory classification systems used in Star Wars lore previously, becoming reference material in the
Star Wars Sourcebooks by
West End Games. The
Victory-class Star Destroyer first described in the early
Star Wars novella, was initially designed as a direct predecessor to the
Imperial-class during the development of
A New Hope, which would make it a follow-up to the
Venator-class seen in
Revenge of the Sith. The
Victory appears very similar in appearance to the
Imperial-class which succeeded it; albeit the
Victory being considerably smaller in scale (900 meters in length versus 1600 meters), adds atmospheric maneuvering "wings" on the port and starboard sides (according to
Star Wars: The Roleplaying Game sourcebooks, the
Victory I-class can enter a planetary atmosphere which is a unique attribute not found in the
Victory II and
Imperial-class Star Destroyers), and a shorter conning tower with different elements on the command bridge. The
Victory-class was developed from a prototype Star Destroyer model created by
Colin Cantwell for
A New Hope, with the final design being used for the basis of the
Imperial-class. ==See also==
