I.K.S. BortaS

Klingon Vor’cha-class attack cruiser. The BortaS (which means “revenge” in Klingon) conveyed Captain Picard‘s request for Klingon assistance at planet Nelvana III when the U.S.S. Enterprise NCC-1701-D investigated reports of a secret Romulan base there. The three Klingon vessels that responded to Picard’s request made it possible for the Enterprise to escape without provoking an interstellar war, despite the hopes of the Romulans.^[1] The BortaS rendezvoused with the Enterprise on Stardate 44246.3, when Chancellor K’mpec revealed that he was dying, and asked Captain Picard to serve as the Arbiter of Succession, leaving Picard in the unenviable position of selecting the next leader of the Klingon Empire.^[2] The BortaS served as Gowron‘s flagship during the Klingon civil war of 2367. Worf served as weapons officer aboard the BortaS during the early part of that conflict.^[3]
