Rock-One was the designation that Rogue Squadron gave to a miid ro'ik cruiser of the Yuuzhan Vong.
Soon after the Battle of Helska IV, Rock-One arrived in the Dubrillion system, functioning as a launch platform for coralskipper probes directed at the planet's surface. During the evacuation of Dubrillion, Rogue Squadron subsequently targeted Rock-One; in the course of the engagement, it deployed interdiction fields that forced a portion of the evacuating convoy to divert from their original course to Agamar and instead head towards Dantooine.
