Yridian starship

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 (NCC-1701-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. 

In 2370, a freighter commanded by Yog rendezvoused with a Klingon Bird-of-Prey controlled by the Duras sisters. The Klingons sold the Yridians several thousand kilograms of magnesite ore stolen from a Pakled mine in the Kalla system. The Enterprise-D, searching for the Duras, arrived in the middle of the transaction. Commander William T. Riker offered one-half gram of Anjoran bio-mimetic gel in exchange for the ore, which he then transported in front of the cloaked vessel then detonated with the ship's phasers. The magnesite reflected off of the Bird-of-Prey, allowing the Enterprise to lock onto the ship with a tractor beam. 

In late 2370, Starfleet put together a Yridian convoy as lure for a Maquis attack. The convoy of six ships left Deep Space 9 for the Demilitarized Zone, destined for Cardassian space, carrying a supplies of isomiotic hyposprays, plasma flares and quarantine pods.

Background information
This unique studio model, which first appeared as a destroyer, and then later as a freighter, was designed by Rick Sternbach. Unlike most other "alien of the week" studio models, this model would not be reused to represent another species' starship.

In the script of "The Chase", the "Yridian attack ship" was described as being "much smaller than the Enterprise-D, but wasp-like and deadly-looking."
