The Raxus Prime Imperial Shipyard was an Imperial Star Destroyer construction facility orbiting Raxus Prime. The shipyard was defended by a fleet of Imperial-class Star Destroyers and a group of Star Destroyers of an unknown class. The shipyard was supplied with metal that was launched up into space from the Imperial Ore Facility, located on the planet surface. In 2 BBY, Galen Marek, Darth Vader's apprentice, came to the planet and raided the Ore Facility on the surface. He commandeered the ore cannon and fired it at the shipyard, destroying it.
