• The station was a large spheroid structure 160 km in diameter and featured 560 internal levels which could contain 2,471,647 passengers and crew. Significantly larger than the previous Death Star, the Death Star II would be approximately 3% the size of the Sanctuary Moon. A large concave dish in the station's northern hemisphere housed its superlaser. Like its predecessor, a throne room would be installed for the Galactic Emperor.

    Owing to the station's stationary and not synchronous orbit, it required a tremendous force to counter Endor's gravity. Utilizing the repulsorlift field created by the shield generator on Endor to maintain its position, the Death Star II created earthquakes, tidal imbalances, and other geological disturbances on the surface below.

  • The most prominent weapon on the Death Star II was its impressive superlaser, which unlike the original Death Star only had a three minute recharge time. Powered by the station's hypermatter reactors, the superlaser would focus multiple lasers through massive green kyber crystals into a single destructive beam. For point-defense capabilities, it featured 15,000 heavy and standard turbolaser batteries along with 7,500 laser cannons and 5,000 ion cannons. It housed 768 tractor beam emplacements, as well as complements of TIE/LN starfighters and their variants for space-based encounters and a plethora of AT-AT and AT-STs for surface operations.

  • The station was powered by several hypermatter reactors, the destruction of which could be catastrophic to the station.

  • With the destruction of the first Death Star in the Yavin system, the Empire was left in a vertiginous state as the Imperial Military reeled at such a sizable loss of its martial forces. With the dissolution of the Imperial Senate and increasing pirate and rebel attacks, the Emperor immediately began construction on a new and improved battle station, one more powerful and without the fatal flaw of its predecessor. To ameliorate the failings of the previous station, Emperor Palpatine executed the Originser responsible for the first station's weak spot, then cloned him to make the second station without any imperfections. Upon the station's completion, the Emperor planned on sending invasion fleets larger than any seen in centuries to blockade the rebellious worlds of Mon Cala and Chandrila until the Death Star could destroy them, effectively ending any hope the galaxy may have in defeating the Empire and its tyrannical regime.

  • Planning to draw the Alliance into a doomed attack against the newer battle station, large portions of the Imperial Starfleet began massing in the Hudalla system in preparations for the upcoming engagement. After members of the Rebel Alliance Starfighter Corps under Corona Squadron arrived in the system, the Empire immediately sent several TIE/LN starfighters to destroy the vessels. Nonetheless, several ships managed to escape and bring their intel back to Alliance High Command, which received further information given to them from the Bothan spynet regarding the Death Star's presumed capabilities, all which was purposely leaked by Palpatine. In an effort to allow its scattered fleet time to assemble over the Outer Rim world of Sullust, the Alliance embarked on Operation Yellow Moon which aimed to distract the Imperials of the buildup until it was too late.

    With the station under construction over Endor when Emperor Palpatine personally oversaw parts of the station's construction, the Rebel Alliance could not resist the opportunity to destroy not only the Empire's newest superweapon, but also its head of state. In reality, the Emperor was leading the Rebels into a trap, resulting in the Battle of Endor. With the station protected on the ground by a SLD-26 planetary shield generator guarded by elite Imperial stormtroopers, along with the largest gathering of Imperial-class Star Destroyers in Imperial history and a fully functional superlaser, total victory for the Empire appeared certain. Nonetheless, the station was destroyed by Lando Calrissian, piloting the Millennium Falcon and his wing of starfighters during the battle, after the ground based shield generator was destroyed by a small rebel strike team who received assistance from the planet's indigenous population, of whom the Empire viewed as no real threat. With the destruction of the second Death Star and Luke Skywalker's victory in converting his father, Darth Vader—once more Anakin Skywalker—to hurl his master down a reactor shaft, the rebels managed not only to prevent further destruction, but presumably end the Empire's oppressive reign once and for all.

  • Following the destruction of the second Death Star, Imperial records would be sent into a state of disarray, with numerous missing persons and unconfirmed dead or wounded.[5] With several thousand death notices to write and records to update, the task would be pushed to the side of Imperial priorities in the days after Endor as the Rebel Alliance would capitalize on its stunning victory by pushing the shattered Imperial forces off of many worlds across the galaxy, including the Emperor's homeworld of Naboo, one of the first to fall. Holovids of the station's destruction would be disseminated across star systems while the Empire would root out and punish those responsible in spreading what it defined treasonous lies. Nonetheless, the truth of the station's destruction would eventually become known to the general citizenry, while both the Death Star I and II would continue to serve as symbol of fear and oppression for years to come, permanently leaving its mark on citizens across the galaxy. With the Empire falling apart, many believed that total victory for the now New Republic was imminent. Nonetheless over a year and four days later Imperial remnants would still be fighting the Republic for control of the galaxy, most notably during the Empire's last stand in the Battle of Jakku. The Galactic Concordance would ultimately be signed mid-battle, formally ending the Galactic Civil War and transforming the Empire into a mere rump state.

    Despite the Empire's defeat at the Battle of Jakku and its total surrender, Imperial fanatics and technocrats would flee deep into the galaxy's Unknown Regions where they would form the Empire's first true successor state, the First Order. A hermit kingdom led by yet another Force practitioner entranced by the destructive capabilities of the original Death Stars, he would ultimately oversee the construction of Starkiller Base, a planet-turned superweapon capable of destroying star systems through sub-hyperspace.
