The Lucrehulk-class battleship was the primary capital ship of the Trade Federation's Trade Defense Force. Most Lucrehulks were modified from enormous cargo haulers. Upgraded and modified versions were later used by the CIS Navy, the Separatist holdouts, the Alliance to Restore the Republic, the Corporate Sector Authority and the even Killik Colony.

At over three kilometers in diameter, the enormous vessel resembled a donut-shape that was missing a section of its circumference and it had a central sphere that contained the ship's bridge and reactor assemblies. The front void of the craft held two mammoth docking bays on either side, which were lined with forward docking claws. These gigantic cargo vessels had been built for many years by the Trade Federation to haul cargo between planets and were an important asset to their enterprise. Housed in the stern of the main body were the main reactors, each connected to one of the three main engines, as well as to secondary engines and each other. The central sphere housed its own reactor/power generator assemblies.
Lining the equatorial bands in batteries of three, were quad turbolaser cannons capable of rotating inwards when not in use. Their limited coverage of the hull made the early battleship models vulnerable, and made them rely more on the massive number of starfighters carried to defend the ships against enemy starfighters. This was, however, rectified with later ships whose armor and shields proved too strong for starfighter firepower, the fact becoming quickly apparent at the Battle of Naboo. The pre - Clone Wars models of the battleships did have major defense flaws, as Anakin Skywalker was able to fly his starfighter into the hangar of a Droid Control Ship and destroy the starboard main reactor by accident. The resulting explosion destroyed the battleship and ensured a Naboo victory.
