Death Star/Legends

"That's no moon. It's a space station." "It's too big to be a space station."

- Obi-Wan Kenobi and Han Solo

A Death Star was an Imperial moon-sized military battlestation armed with a planet-destroying superlaser.

The Death Stars were the first in a long series of superweapons developed to execute the Tarkin Doctrine, but whose concept had been explored even before the Clone Wars. The Death Star was designed to allow Emperor Palpatine to more directly control the Galactic Empire through fear. A Death Star was to be commanded by no one less than a Moff.

Two Death Stars were constructed by the Empire, with a prototype in existence. In addition, a scaled-down version, the Tarkin, and a Hutt knockoff, the Darksaber, would be created by the Empire and Durga the Hutt, respectively.

Both Death Stars were destroyed by the Rebel Alliance shortly after they became operational, with the first Death Star destroyed by Luke Skywalker and the second one destroyed by Wedge Antilles and Lando Calrissian. Following their destruction, other planet-devastating superweapons followed, including the Galaxy Gun, the Sun Crusher, and the World Devastators.

Description
"Look at the size of that thing!"

- Wedge Antilles



The Death Stars, the Galactic Empire's ultimate terror weapons, were battle stations several hundred kilometers in diameter and mounting a directed energy superlaser capable of completely destroying a planet with a single shot. Planetary shields that could have held off entire fleets were ineffective against such a weapon.

The first Death Star was 160 kilometers in diameter, while the second Death Star was 900 kilometers in diameter. Much of its interior space was devoted to systems required to maintain its massive superlaser and power plant. At the heart of each Death Star was a gigantic hypermatter reactor. Within this chamber burned a reaction of prodigious proportions, fed by stellar fuel bottles lining its periphery.

Splitting the station into two equal hemispheres was a huge equatorial trench approximately 503 kilometers in length for the first Death Star and 2,827 kilometers for the second Death Star. This area of the station housed most of the major landing bays, drive thrusters, sensor arrays and tractor beam systems. Halfway between the equator and each pole were two supplementary trenches. The Death Star was divided into 24 zones, 12 per hemisphere, each controlled by a "bridge". To further organize the immense amount of activity aboard, there were specific "sectors" denoting function. These included the General, Command, Military, Security, Service, and Technical sectors.

Since service onboard the Death Star was a long-term affair, the station maintained a number of civilian amenities to make the time aboard a deep space station more comfortable. Parks, shopping centers, and recreation areas could be found in the general sectors of the station.



Facilitating the Death Star's realspace propulsion were a network of powerful ion engines that transformed reactor power into needed thrust. In order for the Death Star to be a deadly threat, it needed to be mobile. Using linked banks of 123 hyperdrive field generators tied into a single navigational matrix, the Death Star could travel across the Galaxy at superluminal velocities. The incredible energies harnessed by the station combined with its great mass gave the Death Star magnetic and artificial gravitational fields equal to those found on orbital bodies many times greater in size.

The Death Star's superlaser derived power directly from the hypermatter reactor. Its faceted amplification crystal combined the destructive power of eight separate tributary beams into one single blast with the intensity of a stellar core. Though the energy output of this blast could be scaled to fire at smaller targets such as capital ships, as was the case during the Rebel assault on the second Death Star, the two major instances in which the superlaser was fired were at full power at planetary bodies. Firing a planetary-destroying shot required the Death Star to generate power equivalent to the output of hundreds of super-giant stars.

The Death Star's interior follows two orientations. Those areas closest to the surface are built with concentric decks with gravity oriented towards the Death Star's core. Past this shell of surface "sprawls", the Death Star's interior had stacked decks with gravity pointing toward the station's southern pole.

History
"Besides, attacking that battlestation ain't my idea of courage. It's more like&hellip; suicide."

- Han Solo



Initially, the Death Star was born in the mind of Raith Sienar, who had conceived of it as an Expeditionary Battle Planetoid. He shared his idea with his friend Captain Wilhuff Tarkin, who presented it to Supreme Chancellor Palpatine. Palpatine, as Darth Sidious, later gave the design to his apprentice, Darth Tyranus, who as Count Dooku, leader of the Confederacy of Independent Systems, presented it to the Geonosians, who created the initial technical designs.

Archduke Poggle the Lesser, leader of the Geonosians, returned the top-secret design to Count Dooku to prevent it from falling into the hands of the Jedi just in time for the Battle of Geonosis. Dooku took the designs back to Coruscant and gave them to Darth Sidious, his dark master.

Darth Sidious kept the design, and later ordered the Death Star's construction after the Galactic Empire was formed, in order to secure his new-formed absolute power. Wilhuff Tarkin was appointed to mastermind the secret development project. Tarkin's creative work and thought had resulted in the realization of the Death Star as the Empire's ultimate weapon.

After the beginning of the Great Jedi Purge, an assault was led on the planet Kashyyyk to enslave the native Wookiees for the Death Star's construction. Various prison planets were also known to have their captives unwittingly construct various sections of the station.



However, the project nearly ended before it began. Because much of the technology of the Death Star was impressive, actually building it proved to be more difficult than anyone imagined. Efforts were not helped by repeated (and often unsuccessful) sabotage efforts.

Of particular concern was the technology required to create the massive superlaser, the very heart of the weapon. To this end, Tarkin brought together some of the most brilliant minds of the Galaxy, including Tol Sivron, Qwi Xux, and Bevel Lemelisk, and built a proof-of-concept model at the Maw Installation. This model would eventually become known as the Death Star Prototype. These scientists also found and corrected several flaws in the Geonosian blueprints, which had been used in that phase of construction.

With the concept completed and the plans finalized, Lemelisk took the plans to Despayre, where construction would finally be completed after twenty years of hard work and the death of many individuals. In celebration, the Death Star turned its massive weapon on Despayre itself, completely destroying it.

During its construction, the Death Star was home to countless prisoners of the Empire, from political opponents to pirate gangs to Rebel saboteurs. These prisoners managed to break out and riot in the Death Star, but were put down by the 501st Legion. However, some managed to escape with a partial set of the plans and some Imperial data. "Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force."

- Darth Vader



Just after construction was completed, the other set of Death Star plans was discovered by Rebel spies on a secret signal interceptions asteroid outpost, AX-235; the Rebellion moved on and in the borders of Operation Skyhook, a copy of the plans was stolen by Kyle Katarn from Danuta and finally reached Leia Organa. Later, while attempting to transport the plans to Bail Organa on Alderaan, Tantive IV was attacked by Devastator above Tatooine. Leia, before being captured, transmitted the plans in R2-D2 and sent them to Obi-Wan Kenobi on Tatooine. On his way to Alderaan, which was destroyed by the Death Star, Han Solo and Luke Skywalker who were escorting Obi-Wan, mistook the station for a small moon while following a lone TIE/ln starfighter. They were soon captured, but after escaping from the Death Star with Leia, the plans to the station were transported by Princess Leia, with help from Han Solo, Luke Skywalker, and two droids, to Rebel leaders on Yavin IV. Soon after, the Death Star arrived to destroy the rebel base. Luke Skywalker piloted an T-65 X-wing starfighter through a minor trench on the surface of the Death Star, evading pursuit by Darth Vader long enough to launch a proton torpedo down a exhaust shaft that reached down into the "reactor core", causing a chain reaction that destroyed the battle station just before it could fire on the Rebel base.

"But Luke... How many Imperial soldiers died when that space station exploded? Were some of them good men? Have you ever considered that? No... I don't think you have."

- Janek Sunber



Nearly four years later, Bothan spies stole the plans of the second Death Star, unaware that their theft was orchestrated by Emperor Palpatine. General Crix Madine and Admiral Ackbar devised a plan for the destruction of the new Death Star. Han Solo led a team to the forest moon of Endor to destroy the shield generator there, while a group of fighters and Millennium Falcon piloted by Lando Calrissian flew into the center of the station through a narrow maze of pipes to destroy the reactor directly, rushing out in just enough time to escape the ensuing explosion before the station could carry out its final order: destroying the Sanctuary Moon itself.

Years later, when Han Solo first encountered the Yuuzhan Vong, he would comment: "Why isn't there a Death Star lying around when you need one?"

Additional information
Around the same time the Geonosians were designing their Ultimate Weapon, Raith Sienar was designing a battlestation (apparently without a superlaser) of similar size and prestige. The best elements of both were apparently merged together with final detail work taking place in the secret Maw Cluster near Kessel. This laboratory completed a scaled-down prototype that was later destroyed by the New Republic.

Design flaws
One drawback of the original design was the power systems. The first Death Star's reactor required one full day to generate enough energy for a full power shot. However, even low power shots were capable of massive destruction on a planetary scale. The second Death Star had redesigned systems and was capable of firing the superlaser once every few minutes. It also had improved targeting computers, allowing it to fire the weapon at capital ships.

There were small gaps in the shields of the first Death Star; the Empire believed that this was harmless since only small ships could wiggle through the gaps. The shields of the second Death Star would have had no such gaps.

The second Death Star also corrected several other flaws in the original design. The two-meter exhaust vent that doomed the first station was replaced with millions of millimeter wide tubes, each designed to seal if excess energy was detected. The second station also boasted far more turbolaser batteries with redesigned targeting systems, allowing them to target starfighters more easily. The greatest concentration of turbolasers was located near the Emperor's throne tower. The other exhaust vents were covered with hyde mollecules that let exhaust out but nothing else in, including, of course, proton torpedoes.

Darksaber
Durga the Hutt also built a small version with only the central laser core and a small living quarters, which was destroyed in the asteroid field around Hoth. This was known as the Darksaber, but shoddy construction techniques meant that this attempt was an abject failure even before its destruction.

Behind the scenes



 * According to the Star Wars: Incredible Cross-Sections fact book, the first Death Star in A New Hope was 160 kilometers in diameter. According to the Inside the Worlds of Star Wars Trilogy fact book and detailed scaling of the station in Return of the Jedi, the second Death Star was 900 kilometers in diameter. Some Expanded Universe sources and starwars.com state much smaller figures&mdash;120 kilometers for the first Death Star and 160 kilometers for the second&mdash;however, most of the evidence argues for the larger sizes.


 * Several of the Star Wars games are concerned with the Death Star's destruction, or the theft, protection, and transmission of its plans until reaching Tantive IV.


 * In Star Wars: Battlefront II, a battle in the Death Star can be played in the Clone Wars-era in Instant Action only. Due to this, it was not an actual battle at all.


 * Both the Droid Control Ship and the Star Forge, also destroyed, had a small sphere in their middle as a tribute to the Death Star.


 * A number of Death Star battlestations appear in sources of uncertain canonicity. The Star Tours theme-park ride includes another battlemoon at Endor, clearly different than the one seen in Return of the Jedi, while the French-language RPG Magazine Casus Belli 99 includes another prototype, named the Nocturn&.

Physics
It has been calculated that blowing up an Earth-sized planet takes on the order of 10^{32} joules of energy; this is roughly the total output of the Earth's sun in a week. More detailed estimates place the violent destruction of Alderaan as requiring 10^{38} joules of energy, or roughly one million times that necessary to permanently break apart the planet. The prototype Death Star destroyed the moon of the planet Kessel. While there was little detailed information about this event, it would have required around 10^{29} joules, assuming similar size and composition to Earth's moon.
