The IKS Hegh'ta was a Klingon Bird-of-Prey that was in service with the Klingon Defense Force in the mid-24th century. In 2368, the Hegh'ta was under the command of Captain Kurn.
In that year, the Hegh'ta fought for the forces loyal to Gowron during the Klingon Civil War in 2368. (TNG: "Redemption", "Redemption II")
Translated from the Klingon language, the ship's name means "continuing death" or "everlasting death".
