The Pralor vessel was a type of starship initially utilized by the Pralor and were nearly identical to Cravic ships. They were crewed by Automated Personnel Units in the 2370s.
Tinted gray, their design consisted of a central hub from which five arms extended in a star-like formation. One of the areas of the ship was a reconstruction bay where damaged Automated Personnel Units were fixed. These vessels possessed weapon systems "substantially superior" to those of the USS Voyager, using quantum resonance charges as their primary armament, the also discharged disruptor blasts. Defensively, they employed a complex subspace defense field, which meant Voyager's weapon systems posed very little threat to the Pralor vessel. However, at optimal efficiency, Voyager's engines were more powerful than those aboard the Pralor vessel.
The crew included Designated Command Units and fire units. Tactical decisions for the ship were made using tactical subprocessors.
The ships were 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 vessels to continue the war for at least another fifty years. (VOY: "Prototype")
The script described this vessel as "an alien ship, somewhat larger than Voyager, and distinguished by sleekly curved surfaces."
From a bird's-eye view, the ships look suspiciously similar to a unicode asterisk (*).
