IKS Kring was a Bre'el-class Klingon starship in service to the Klingon Defense Force. By 2373, it was considered obsolete and delapidated, with inferior weapons systems. That year, the Kring was under the command of Commander Ngabwi, with Lieutenant Grudzeqi as first officer. The Kring and its crew were part of the plot that year to assassinate Starfleet Captains Jean-Luc Picard and Benjamin Sisko. The Kring was destroyed in a plasma storm in the Badlands.
