Kas's battlecruiser

Kas's battlecruiser was a Klingon Empire battlecruiser starship in service in the early 25th century. The ship saw action during the Federation-Klingon War of 2405-2410. 

History
In the year 2409, Ambassador Kas represented the Klingons in the abortive peace negotiations with the Federation on Regulus IV. The diplomatic effort had been setup to fail by a rival of Kas's Great House, Admiral B'vat. When B'vat arrived in his flagship, Ambassador Kas returned to his battlecruiser and joined forces with a Starfleet starship defending Regulus IV. Together, they fought off B'vat's escorts and forced him to retreat. Kas's battlecruiser remained in orbit of the planet.
