IKS Mek'leth was a Klingon K't'inga-class battle cruiser.
In 2267, the Mek'leth was stationed near the Federation border. First Officer Faren killed Captain Krann and took command of the Mek'leth, then took the Mek'leth into battle with James T. Kirk's USS Enterprise near Organia, where it was destroyed. Kang thought Faren a fool, but regretted the loss of the crew of the ship.
