The IKV Deftslayer was a 23rd century Klingon Empire starship, a D7C-class command battle cruiser in service to the Klingon Defense Force in the 2290s. While the Deftslayer was outfitted as a D-7C command battle cruiser, it was easily modifiable with additional phasers into a refit version, the K't'inga-class variant D7L-class command ship. (TOS video game: Starfleet Command)
