- "Attack those Federation starships, quickly!"
- ―Obi-Wan Kenobi, during the Battle of Geonosis
Core ships were modified Lucrehulk-class battleship central spheres that were used by the Trade Federation for planetary landings during the Clone Wars. Equipped with both land and air defenses, those autonomous spheres were 696 meters in diameter. Several such ships were deployed at the Battle of Geonosis. Skytop Station was a core ship converted to serve as a listening post.
