Jach class

The Jach class was a type of battle cruiser used by the Klingon Empire during the mid-23rd century. It was similar to the Chargh-class, but could be differentiated by the presence of a third, central hull between the two outer hulls.

At least one vessel of this class fought in the Federation-Klingon War of 2256-57, starting with the Battle of the Binary Stars in 2256. (DIS: "Battle at the Binary Stars")

The name of the class translates to "Scream" or "Shout" and was developed by writer Kirsten Beyer. [1]
