Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
Grand Moff Tarkin
He allows the Rebels to escape the Death Star with the Princess after placing a tracking beacon on the "Millennium Falcon" in order to find the Rebel base. He orders the Death Star to destroy the Rebel base on Yavin IV. In the film's climax, Tarkin refuses to believe that the Death Star is in danger from the Rebel starfighter attack. As such, he refuses to evacuate. Subsequently, he is killed when Luke Skywalker succeeds in destroying the Death Star.
