The Lokirrim patrol ship was a type of medium-sized starship used by the Lokirrim to patrol their territory. The ship was equipped with a tractor beam and a photonic disruptor, which could be used to remotely decompile holograms. It was tactically outmatched by the Intrepid-class starship.
In 2377, a Lokirrim patrol ship commanded by Ranek attacked the Delta Flyer after detecting The Doctor, whom they mistook for a photonic insurgent. The crew of the Flyer were detained aboard the ship until they were freed by the USS Voyager. (VOY: "Body and Soul")
