IKS Ehhak

IKS Ehhak was a Klingon starship in Imperial Defense Force service in the 23rd century. Ehhak was one of the vessels that was present at Organia in 2266 when the Organians intervened in a war between the {Federation]] and the Klingons.

James T. Kirk recalled this, years later, when it detected that the Romulan starship ChR took on the name Ehhak as part of a ruse to fool the Federation into thinking that Klingon vessels were massing on their borders. (TOS novel: "My Enemy, My Ally")
