The Weapon Development Facility, also referred to as the Imperial Weapon Research Facility, was a research installation of the Galactic Empire situated on the planet of Naboo during the era of the Galactic Civil War.
The Empire constructed the Imperial Weapon Research Facility shortly after the Battle of Yavin. This highly confidential and restricted zone was defended by a stormtrooper garrison along with several AT-STs. A commoner hailing from Kaadara stumbled upon the Facility after becoming disoriented while traveling from Theed to Moenia. Roric V`lia, a Naboo noble, along with his employee Vaik'anna Silverlight, engaged in activities connected to the Facility.
By 1 ABY, the Weapon Development Facility had evolved into a heavily contested area within the Galactic Civil War, with Imperial and Rebel forces engaging in multiple battles for control of the site. Although Rebel forces succeeded in capturing the facility on several occasions, Imperial forces consistently managed to reclaim it.
The superlaser that was installed on the Star Destroyer named Conqueror was engineered at this research facility. Inside the facility were fabrication chambers and testing bays, along with a main control room that housed computer consoles containing information pertaining to the Star Destroyer. At that time, the Sith Acolyte Namman Cha was responsible for guarding it. In 1 ABY, the Renegade Squadron of the Rebel Alliance raided the facility, defeating Cha and acquiring crucial data about the Conqueror. They subsequently utilized this information to locate and destroy the vessel.
The Imperial Weapon Research Facility was featured in the 2003 video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game that was created by Sony Online Entertainment and published by LucasArts, before its shutdown on December 15, 2011. The Imperial Weapon Research Facility was transformed into a "Factional NPC Base" with the release of the "Publish 1" update on August 3, 2003. Rebel player groups could attack Imperial NPCs and complete various objectives in order to seize control of the base.
