The CDS Rugg'l was a Galor-class Cardassian warship in service in the 24th century. By 2371, the Rugg'l was under the command of Gul Fransu.
In 2371, the ship was undergoing refit when Fransu discovered that the High Gul, whom he had hidden on Terok Nor while it was under contruction, had been revived. Fransu took the Rugg'l to the Bajoran system, and proceeded to launch an unsanctioned attack on Deep Space 9. The crew of Deep Space 9 and the High Gul were able to defeat Fransu, heavily damaging the Rugg'l in the process. The Rugg'l continued to fire, and was fired upon by a Federation task force sent to investigate the situation, wrecking the ship in the process. (DS9 novel: Station Rage)
