The Gel'tar-class was a type of battleship that saw service in the Klingon Defense Force during the Dominion War. (The Dominion War Sourcebook: The Fires of Armageddon) This ship clashes with a statement made in another Spacedock! sourcebook, the Ship Recognition Manual, Volume 3: Ships of the Klingon Empire. That states that only two types of battleships were fielded by the Klingons around this period, the Negh'Var-class and the Gel'joQ-class. It is possible that the Gel'tar class might be a misspelling of the latter.
