The Yridian destroyer was a type of starship used by the Yridians during the late 24th century.
In 2369, a destroyer intercepted Dr. Richard Galen's shuttlecraft and placed it in their tractor beam. The Yridians were interested in obtaining Galen's research regarding an ancient software program hidden within the DNA of several species, which they wished to sell to the Cardassian Union. The Yridians boarded the shuttle and stole several bits of information from his computer. The USS Enterprise-D intervened and ordered the destroyer to stand down. In response, the Yridians fired at the Enterprise, however, because the destroyer was overloading its power generators, it was inadvertently destroyed when it was hit by a single phaser blast from the Enterprise. (TNG: "The Chase")
Background
This unique studio model, which first appeared as this ship, was designed by Rick Sternbach and - unlike most studio models - this model, outside of the appearance of a Yridian freighter appearing in TNG Season 7, would not be reused to represent any other starship classes.
According to the script, this "Yridian attack ship" was "much smaller than the Enterprise, but wasp-like and deadly-looking."
