The IKS Koltar was a Khin'Vagh-class starship under construction at Praxis Station, slated to enter Klingon service during the 25th century. It was slated to include red trim, which earlier units lacked.
The first officer of the IKS Khin'Vagh, Lartika, was promised the command of the then-under construction IKS Koltar upon completion if he won a golf tournament whose prize was a Federation starship design team. (Star Trek: False Vacuum: "Pothole Omnium")
