The Lucrehulk is one of the largest classes of starship seen in Star Wars, measuring 3170 meters in diameter, enough to dwarf Imperial Star Destroyers. It was composed of an outer ring with hyperdrives and large engines and a separable inner ' core ship' that was capable of landing on planets. The Lucrehulk-class battleship was the primary capital ship of the Trade Federation before and during the Clone Wars. A Lucrehulk-class battleship in the Naboo blockade
