|~ General Hux about the Starkiller Base.|
The Starkiller Base was an icy planet in the Unknown Regions that served as the headquarters of the First Order 3 decades after the Battle of Endor 30 years ago from Star Wars: Episode VII The Force Awakens. The base was commanded by Genral Hux and was armed with a superweapon capable of destroying entire star systems such as the Hosnian system, which the First Order viewed as an evolution of the planet-destroying capabilities of the Galactic Empire's Death Star.
Starkiller Base was a mobile ice planet located in the Unknown Regions that served as a stronghold of the First Order thirty years after the Battle of Endor. Commanded by an unofficial triumvirate of General Hux, Kylo Ren and Captain Phasma, it was armed with a superweapon capable of destroying entire star systems halfway across the galaxy.
The First Order viewed this ability as an evolution of the planet-destroying capabilities of the Galactic Empire's Death Star designs, with the weapon serving as the ultimate culmination of Old Empire research into dark energy translations and hyperspace tunneling.
Under Snoke's order, Hux used the Starkiller Base to fire on the capital of the New Republic, Hosnian Prime, and four other planets in the Hosnian system, utterly destroying the planets and a significant portion of the New Republic's fleet. This is a crime of an even greater scale which succeeded the destruction of Alderaan committed by Grand Moff Tarkin.
The Starkiller Base was ultimately destroyed by a Resistance attack due to a weak point exploited by pilot Poe Dameron, causing the implosion of the entire planet as the superweapon was firing upon the Resistance base on D'Qar, which is a way of destruction similar to that of the first Death Star. The stored stellar energy then expanded, causing the planet to turn into a star.
