In the latter half of the 24th Century, the Klingon Empire saw fit to begin upgrading several of their aging designs with new technologies. In particular, the K'T'inga Battlecruiser saw many different modifications and upgrades to lengthen their service lives. One such variant is the K'Targha Escort Battlecruiser.
Exchanging its heavy photon torpedo for a heavy disruptor and its aft photon torpedo for another medium disruptor, the all-beam K'Targha serves as heavy escorts for Vor'Cha Attack Cruisers in the field. The K'Targha battlecruisers are cheap and expandable by Klingon terms and more than adequate for screening for larger capital ships.
