IKS Bortas (D5 class)
The IKS Bortas was a Klingon  battle cruiser that was in service with the Klingon Imperial Fleet in the mid-22nd century. In 2152, the Bortas was under the command of Duras, son of Toral.

In that year, the Bortas was assigned to locate and capture a refugee ship from the Klingon protectorate of Raatooras. Tracking the ship to a system just outside of Klingon territory, the crew discovered that it had been rescued by the Human vessel . The Bortas subsequently engaged in battle with Enterprise, but was disabled when Enterprise lured the Bortas into the rings of a gas giant and ignited the plasma. For his failure to apprehend the refugees, Duras was reduced in rank from captain to second weapons officer. ()
