The Akritirian patrol ship was a type of starship used by the Akritirians to enforce laws in their space.
In 2373, two patrol ships attacked the USS Voyager in an attempt to impound the ship, causing Voyager to retreat.
Two more patrol ships later attacked Neelix's ship Baxial during its mission to rescue Tom Paris and Harry Kim from the Akritirian maximum security detention facility. (VOY: "The Chute")
