Bakka is an Imperial Mining World and Forge World made famous across the galaxy by its orbiting shipyards, which have been in use to build new starships for the Imperial Navy since the early years of the Great Crusade in the 30th Millennium. Bakka serves as the primary Segmentum Naval Base for Battlefleet Bakka, providing coordination for all Imperial Navy forces in the region and serving as the primary point of resupply and repair for all the Imperial battlefleets now operating in the Segmentum Tempestus.
