Yridian freighter.
The Yridian freighter was a type of freighter used by the Yridians during the late 24th century.
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. (TNG: "Firstborn")
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. (TNG: "Preemptive Strike")
