The IKS Koraga was a Klingon Bird-of-Prey that was in service with the Klingon Defense Force in the late 24th century.
In 2375, the Koraga, under the command of Lieutenant Commander Worf, and the IKS Rotarran were ambushed by a Jem'Hadar patrol near the Badlands. The Koraga was destroyed, although six starboard escape pods were recovered by the Rotarran. The USS Defiant searched the area for an additional three days, until it was forced to retreat by Dominion forces. Worf's pod, launched from the port side, had been swept into the Badlands and was only found much later by the runabout USS Gander. (DS9: "Penumbra")
According to the script for the episode , the pronunciation for Koraga was "kuh-RAW-guh".
