After the mineral-rich planet Rothana was discovered in Wild Space in 800 BBY, its location was sold to Kuat Drive Yards. KDY dispatched Quiberon Kuat to the planet with thousands of workers and a fleet of ships, creating a network of mines, factories and shipyards that was the foundation of Rothana Heavy Engineering.
RHE became Kuat's primary subsidiary for pursuing secret projects. Far away from the Core Worlds, it was isolated from corporate espionage and only accessible by an incredibly-convoluted network of hyperspace routes, the locations of which were issued on a strictly need-to-know basis.
In 31 BBY, Rothana Heavy Engineering received an immense order from the cloners on Kamino to create war machines for the Galactic Republic's clone troopers and army. Working in absolute secrecy for nine years, Project Icefang oversaw the development of thousands of new assault ships, dropships, and walkers. Equipment was shipped to Kamino via the Quiberon Line, where the growing clone army tested and trained on their new machines. A handful of field tests were conducted elsewhere, but they were so few that sightings of AT-TEs and other new designs were dismissed as fantasies.
Smaller Rothana warship models were noted for their characteristic "arrow"-shaped command towers. As the Clone Wars progressed, the shipyards quickly supplemented its successful assault ships with larger and more advanced designs such as destroyers and battleships.
After the Clone Wars ended, Rothana would still design and produce weaponry and vehicles for the Galactic Empire, but would not be as prominent as they were before. Still, even during the Galactic Civil War, certain designs would still be influenced by their style. The Rothana yards were ultimately abandoned by the Galactic Empire just after the Battle of Endor in 4 ABY.
