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.
Death Star
"" features Starkiller Base, a planet converted into a superweapon built by the First Order. Significantly larger than either the first or second Death Star, and unlike either of those cost-prohibitive space stations, this superweapon cut-costs by terraforming an existing planet and draws its fire power directly from a sun (by extracting a kind of Dark Energy called Quintessence and turning it into another type of dark energy called Phantom Energy), but it requires time to draw enough energy. Once fired, it has the power to destroy up to five planets within the same star system simultaneously, making it a far deadlier superweapon than the Death Star. General Hux gave an intense speech while Starkiller Base demonstrated its lethality by obliterating the five planets of the Hosnian Prime system (the location of the Republic government, which rotates every few years), the cataclysm witnessed by Han Solo, Chewbacca, Rey and Finn from Maz Kanata's castle. After Rey was captured by Kylo Ren, he interrogated her within the base. Han, Chewbacca and Finn approached the base at light-speed because the Starkiller's shield kept out anything going under the speed of light. They found Rey and successfully lowered the protective shields, enabling an X-wing assault led by Poe Dameron and Nien Numb to destroy the planet-converted superweapon, with Poe firing the crucial, destructive shots. The name Starkiller Base paid homage to the early drafts of the original Star Wars film, referring to Luke Skywalker's original name as Luke Starkiller.
