Tan in color, their design consisted of a central hub from which five arms extended in a star-like formation. These vessels were presumably armed with the same weapon systems and capabilities as their Pralor counterparts.
They were crewed by Automated Personnel Units and used in the war between the Pralor and the Cravic. However, when the war ended and the Pralor and Cravic attempted to terminate the units, the units killed both species. The units used the Pralor and Cravic starships to continue the war for at least another fifty years.
In 2372, one of these vessels, commanded by Automated Commander 122, engaged a Pralor starship, commanded by Automated Unit 6263, and was capable of breaking through the Pralor vessel's subspace defense field. (VOY: "Prototype")
