Klingon Bird-of-Prey that served as General Martok's flagship during the later years of the Dominion War.
The Ch'Tang was a Klingon Bird-of-Prey that served as General Martok's flagship in the later years of the Dominion War, when he commanded Klingon forces fighting alongside Starfleet from Deep Space Nine.
In Once More Unto the Breach, Worf persuaded Martok to accept the aging warrior Kor among the crew of the Ch'Tang, despite Martok's old grudge against him. When a Jem'Hadar force caught the Klingon squadron, Kor took command of another Bird-of-Prey and stayed behind to hold off the enemy, buying time for the Ch'Tang and the rest of the ships to escape.
