The idea for the Death Star began when the Confederacy of Independent Systems designed the Ultimate Weapon, using plans and concepts provided by Wilhuff Tarkin. Poggle the Lesser possessed the original (or a copy of the) plans, which he handed to Count Dooku during the First Battle of Geonosis.
An alternate version of this story served as the opening mission of Star Wars: Dark Forces, with Kyle Katarn, a newly defected Imperial, running missions for the Alliance, one of which saw him breaking into an Imperial compound on Danuta and stealing the Death Star plans.
As part of a devious scheme masterminded by Emperor Palpatine to destroy the Rebel Alliance, the plans were delivered into the hands of the Alliance through Black Sun leader Prince Xizor, under the guise of being stolen, providing them with the technical data needed to formulate the assault on the Death Star, ...
The construction of the first Death Star continued for several years above Geonosis in utmost secrecy, under Admiral Wilhuff Tarkin's supervision. The Empire utilized construction modules operated by Wookiee slave laborers and various other species to complete the project.
Attack of the Clones saw Dooku taking the plans for the Death Star from Poggle the Lesser, the Geonosian leader who had pledged support to Dooku's Separatists.
That datacard – briefly glimpsed in Rogue One as the Rebel ship is attacked by Darth Vader – is seen again in an early moment from A New Hope, when Princess Leia furtively transfers the Death Star plans to R2-D2.
Stolen during the Battle of Scarif by the Rogue One squad at the cost of many Rebel lives, the remaining copy of the blueprints were transmitted to the MC75 Star Cruiser Profundity, where members of the Alderaanian consular security transferred the plans into the datacard and evacuated to Princess Leia Organa's ...
Essentially, the Empire was able to build the second Death Star so quickly because they'd already built one before. Furthermore, Darth Sidious expedited the construction of the second Death Star so that it was functional far sooner than the first.
But what made the Death Star particularly menacing was its ability to travel through hyperspace. Not only was it equipped with destructive armaments, it could pursue its prey with those armaments.
As Emperor, Palpatine retained the emergency powers that had been voted to him during the Clone Wars, allowing him to rule under what amounted to martial law. He could execute, imprison, exile, banish, or confiscate anyone or anything solely on his authority.
A Sith Lord with the ability to cheat death and create life, Plagueis is the enigmatic mentor of Sheev Palpatine / Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
The plans contain the Death Star's entire design history, including the flaw introduced into its reactor system. Stolen by Jyn Erso, they are beamed to the Profundity, copied and hidden in the memory systems of a humble astromech droid.
One major reason Kyle Katarn's canon status is in limbo is because his most significant act has been directly contradicted by the rebooted canon. The opening mission of Star Wars: Dark Forces has Katarn stealing the Death Star plans, setting in motion the events of the original trilogy.
Kyle's power seems to mainly stem from his time visiting the Valley of the Jedi. His accomplishments primarily consist of defeating various Dark Jedi, however, the only Sith Lord he fought, Caedus, dispatched of Katarn rather easily.
No, he's just not canon anymore, being solely on the Legends continuity. Kyle's roles in the overall lore has either been taken by other various characters and he's….
In short, don't count on it happening anytime soon: The actual size of the Death Star, according to their estimations, is close to 120 to 160 kilometers in diameter, and would cost the equivalent of 18 quadrillion dollars to build.
In the original Star Tours, a Death Star III is seen and destroyed during the ride sequence by the New Republic. Leland Chee originally created the third Death Star to explain why a Death Star is present on the Star Tours ride when both of the stations in the movies were destroyed.
Hyperspace courses were often plotted using a planet's mass as a backstop, with the hyperdrive's safety systems automatically stopping the ship as it reached the farthest point of possible travel. Hyperspace collisions, whether they be intentional or by accident, could devastate or even destroy a planet.
It was two-three times larger than DS1 and took far more materials to build it. Sid also wanted it to look unfinished so he could lure the Rebels in: “it's a trap!” But he ensured the planet killer gun was operational by sending Vader in to oversee it.
Some Expanded Universe sources state much smaller figures—120 kilometers for the first Death Star and 160 kilometers for the second—however, most of the evidence argues for the larger sizes.
Eventually, Skywalker went into exile on Ahch-To and took the saber with him, storing it inside his hut. After Skywalker's death his Force spirit gave Organa's lightsaber to Rey, as he believed Organa would want the Jedi Padawan, of whom she had picked up training herself, to have her weapon.
Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection. Vader's denial of Anakin Skywalker's legacy and his fear of getting hurt again prevented him from realizing the truth about his children until later in the original trilogy.
Darth Vader may have never known Princess Leia was his daughter in Star Wars and never cultivated a relationship with her, even when he was a Force ghost. Anakin Skywalker never knew Padmé was pregnant with twins, and he believed his child had died with his wife.
