The IKS Deathcry was a Klingon Empire starship, a K't'inga-class battle cruiser in service to the Klingon Defense Force in the late 23rd century.
In 2273, the Deathcry was one of three battle cruisers who were ordered to travel to Earth and receive a full account from the Federation Council regarding the destruction of the IKS Amar and several other Klingon warships by the V'Ger cloud entity. En route, mission leader Commander Krell ordered all ships to pursue the USS Enterprise to the Scylla sector in the hopes of capturing the advanced Constitution-class vessel. The Enterprise managed to win the engagement and the Deathcry and the IKS Ravager were forced to tow Krell's stricken battle cruiser back home. (TOS - Untold Voyages comic: "Renewal")
