The Utopia Planitia Naval Shipyards, also known as UPNS or the Utopia Planitia Fleet Yards, was a key military shipbuilding corporation in the galaxy at the time of the Galactic Civil War, based on Planitia.
UPNS mainly sold its products to the Galactic Empire, and the Galactic Republic previously. Many UPNS products were composed of the same single-hull saucer section-engineering section-impulse nacelle configuration, and this configuration became the trademark of all UPNS ships. Utopia Planitia did not sell only to the Imperials, however; many planetary governments purchased its weapons for the purposes of defending their planet from the war. Following the Rebel capture of Planitia, where the main shipyards were based, UPNS bean supplying the Rebels with ships. These circumstances helped to make Utopia Planitia one of the most famous corporations in the galaxy.
