The I.K.S. Rotarran is Klingon B’rel-class Bird-of-prey. After suffering a number of defeats in combat with the Jern’Hadar, the morale of the crew was extremely low. General Martok assumed command and, aided by Worf and Jadzia Dax, brought honor back to this “cursed” ship. Martok later took the Rotarran as his flagship during many battles in the Dominion War.
