It was the most powerful warship fielded by the Klingon Empire for some time and one even served as the flagship of the Klingon Chancellor. 

The class would continue to serve in the Klingon fleet in the 2370s, a hundred years after it entered service. It was involved in several major conflicts in that decade including the Klingon-Cardassian War, Second Federation-Klingon War and the Dominion War.
