The first "Death Star"
Most of the procedures in this section of the events shown in the movie Star Wars: Episode IV. A New Hope.
"Death Star" was designed before the start of the Clone Wars (the separatists wanted to use the Death Star against the Republic, but its construction was never started due to the invasion of Geonosis - drawings of the "Stars .." were given to Darth Sidious, who immediately found a use for them, when he became Emperor), but was later handed over to the Empire, namely Cinara Wright and Bevel Lemelisk commissioned by Grand Moff Tarkin to monitor the external territories. Initially, the project was intended to destroy the dead planets in order to facilitate the extraction of minerals, but the idea Tarkin, the station is able to blow up the planet, was to terrify the population subject to him sectors and completely eliminate any possibility of resistance to imperial power. In this project used the Sinar "Great Arms" geonozistsev created before the Clone Wars. The construction of the station was completed in the year of the Battle of Yavin.
Tarkin was eager to try out new weapons. Soon, he was given such an opportunity: Darth Vader captured Rebel Princess Leia agent who was carrying the stolen Death Star plans to the rebels, but managed to hide them, and brought her to the station. As the popularity of the Rebel Alliance has continued to grow, the Empire urgently needed to stop this process, the more the insurgents could find a weak spot in the plans of the station and destroy it. Vader was trying to torture with the help of, robot-hangman to get Leia to give the location of the secret base of the Alliance and to confess to plans were hidden, but she did not succumb. Then, Tarkin brought "Death Star" to Alderaanu - home planet of Princess, and said that if she will not give him a Rebel base, it will destroy Alderaan. In a panic, Leia told him that the base is located on a remote planet Dantooine, but Tarkin did not stop the execution of Alderaan, as he was required to teach a lesson to all rebels, and the destruction of populous planet in the galaxy's center that supports the rebels could not be better suited for deterrence.
Secret Star plans were hidden inside the Levi-astromehanika droid R2-D2, who was ordered to find Obi-Wan Kenobi, who, along with Luke Skywalker, Han Solo, Chewbacca, and C3PO robot translator were in the dock of the Death Star in 2037 aboard the Space Shuttle " Millennium Falcon, "which was captured by attracting ray stars almost immediately after the hyperspace of a non-existent Alderaanu.
Soon after, Luke Skywalker and Han Solo helped Lee escape, but their ship was hanged beacon, a signal which found that the rebel base is located on the fourth moon of the planet Yavin. "Death Star" went there to deliver a crushing blow to the Alliance. Meanwhile, the rebels, having analyzed the stolen plans to Leia station, found that the only way to destroy the well-protected station - hit its main reactor through the exhaust port, ending a hole diameter of about two meters. When the "Death Star" arrived in the Yavin system, she was met with rebel fighter units. Thus began the Battle of Yavin, the date which later became the beginning of the chronology of the New Republic. The rebels suffered heavy losses, but before the "Death Star" was able to reach the firing position, the Luke Skywalker got to hit the reactor station Proton rocket (torpedo), and "Death Star" exploded. Tarkin was killed along with his brainchild, and Vader, who participated in the defense, was thrown away into space aimed shot Han Solo. This victory allowed the alliance to strengthen their positions, but the Empire was still very far from defeated.
Enraged by the death of Emperor Palpatine station subjected Lemelisk, who considered himself guilty of the lesion, painful death. Pre-clone was grown Lemelisk, which (after moving to a card design techniques with Sith) have led to design a new, even more enormous, "Death Star", which would have been without drawbacks of its predecessor. From time to time, Palpatine executed again and again Lemelisk created his clone.
The second, "Death Star"

The new Death Star has turned even more powerful and invulnerable than its predecessor. Unfortunate ventilation shaft that leads directly to the reactor was replaced by a complex and extensive system of pipes, by millions of millimeter-ending holes on the surface, with fuses in case of explosion. The reactor was able to gather energy for a shot a few minutes (the previous version required about a day). Focusing device made it possible to beam pointing not only to the planet, but also on large ships. In addition, the Death Star, located at the planet Endor, defended by a force field generator is located outside the Star. On the surface battle stations were scattered over thousands of laser guns, as well as hangars for shuttles and fighters.
The cunning plan devised by Emperor Palpatine, was whether to create the illusion of the Rebel Alliance in Star vulnerabilities. To do this, however, first necessary to find and disable the force field generator. The data obtained by the scouts of the Alliance (and sometimes - at the cost of living), revealed that he is on the forest moon of Endor and poorly guarded. But in fact, leaked data was adjusted by the Emperor as a trap, waited for Han Solo and his party rebels on Endor. Thus the Emperor hoped to lure and destroy the entire Rebel fleet, which will be sent to a diversion from the main Imperial attack. Nevertheless, resourcefulness and luck of heroes, not only allowed them to escape from the trap of empire, but did destroy the generator. They greatly helped the people of Endor, small intelligent animals, Ewoks, like little bears. Then link the Alliance fighters, led by Lando Calrissian, pilots the "Millennium Falcon" to the ventilation system crept to the reactor (as a star has not completed) and destroyed it, barely having time to get away from the explosion.
