The Chut'Duj class was a type of impulse patrol ship fielded by the Klingon Empire during the 24th century. (Ship Recognition Manual, Volume 3: Ships of the Klingon Empire) The Chut'Duj used a variant of the B'rel-class hull design that lacked warp nacelles. The space saved removing the nacelles contained 150 highly secure jail cells for the transportation of criminals. Since it lacked the ability to go to warp speeds it was confined to the system it was assigned.
