The IKS Rovlaq was a Vor'cha-class starship in service to the Klingon Defense Force in the late 24th century. In early 2380, Drex, son of Martok was assigned as her commanding officer.
During the Borg Invasion of 2381, the Rovlaq was one of only two ships to have survived the defense of the Mempa system from Borg assault, and managed to destroy one of the twenty-four Borg cubes that were part of that battle. The Rovlaq suffered significant casualties in that battle, and remained understaffed in the following months, when it was assigned to escort refugees from Mempa to the planet Krios. On approach to Krios, the Rovlaq and the refugee fleet were ambushed by a dozen Kinshaya ships. Though they were able to destroy ten of their attackers, the Rovlaq suffered a catastrophic hull breach and was destroyed with all hands. (ST novel: A Singular Destiny)
