A Vor'cha class attack ship and two Bird of preys attack the USS Pittsburgh (NCC-2195-B) in the year 2395. even after the Klingon Civil War, the ideas of the Duras sisters were kept alive by lonely renegades randomly attacking ships. In the early 2390's, the renegades began attacking federation ships, and by 2395, four ships were destroyed and twelve others were damaged. But by 2415, the rebels had gave up due to the launch of the Insignia, Charlotte, and the Negh'var class.
