Vorok's battle cruiser firing a torpedo. (ENT: "Unexpected")
This model was a very much 'unexpected' reuse of the K't'inga-class battle cruiser. It was admittedly a modeling error on the part of the visual effects department, which originally built a new model that did not fit expectations. Due to time constraints, they were unable to make the necessary repairs to the new model and were forced to replace the model with the battle cruiser model previously built for Star Trek: Deep Space Nine.
