The Lusankya was an Executor-class Star Dreadnought, a type of Star Dreadnought, that was commissioned for the Galactic Empire's navy. Following the Imperial Death Star's destruction during the Battle of Yavin in 0 BBY, the Super Star Destroyer project's strategic value to the Empire was amplified. While its sister ship, the Executor, was in its construction phase at the Fondor Shipyards, the Lusankya Star Dreadnought was being put together at the Kuat shipyards of Kuat Drive Yards at that time.
Within current Star Wars canon, the Lusankya made its debut in issue number twenty-seventh issue of the magazine series Star Wars: Build the Millennium Falcon, released by De Agostini around July 8 of 2015. Conversely, in Star Wars Legends continuity, the Lusankya was initially referenced in the novel X-Wing: Rogue Squadron, the first book in the Star Wars: X-Wing series, authored by Michael A. Stackpole and published on January 1 of 1996. Subsequently, the Lusankya physically appeared for the first time in the series' third novel, X-Wing: The Krytos Trap, also written by Stackpole and released on September 1, 1996.
The author revealed that its name was derived from the Lubyanka, a Russian governmental building utilized by various secret police forces, explaining: "I wanted it to sound much like the inescapable prison in Moscow because I wanted the Lusankya to be inescapable." Its first visual representation was in the 1998 comic-book Crimson Empire 5, an issue belonging to the Dark Horse comic-book series titled Star Wars: Crimson Empire, penned by Mike Richardson and Randy Stradley, and featuring illustrations by Paul Gulacy along with P. Craig Russell.
