The Yridian starship was a starship type used by the Yridians during the late 24th century as a destroyer and a freighter. 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, and was inadvertently destroyed when hit by a single phaser blast from the Enterprise. (TNG: "The Chase" )
