Camp ships were Yuuzhan Vong ships used to house refugees after the Battle of Coruscant. Made of masses of hexagonal chambers of various sizes glued together, they lacked life support systems, engines, or any kind of supplies. The Yuuzhan Vong filled them with millions of Coruscanti refugees and sent them to inhabited systems, which faced two options: either help feed the refugees, or let them die aboard the ships. With most systems' resources already strained by the necessities of the war, few had spare supplies, but none could neglect the needs of so many people.
