The B-5 Decimus was a model of bomber produced by the shipyards at the planet Sernpidal for the Sith Empire, and was named after its commissioner, the Sith Lord Darth Decimus. The B-5 Decimus, which was armed with heavy laser cannons, either missile or torpedoes as secondaries, and various mines and drones as options for its auxiliary weapons, was banned by the Treaty of Coruscant for its frequent use by the Empire against civilian populations in the Great Galactic War, though it saw use again in the Galactic War.
