Vessels of this type were not nearly as advanced as Federation starships of the time, as their weapons would have had no effect. In 2365, a vessel of this type (temporarily under the command of Debin, ruler of the Atlec people) intercepted the USS Enterprise-D and a Straleb security vessel. He demanded they give Thadiun Okona over to them for impregnating his daughter, Yanar. The misunderstanding was later settled aboard the Enterprise. (TNG: "The Outrageous Okona" )
