IKS Ghaklor

The IKS Ghaklor was a Klingon starship, a battlecruiser in Imperial Defense Force service in the 23rd century. 

History
By 2270, the Ghaklor was under the command of General. That year, the general lost the signet to his Noble House to Federation Starfleet Lieutenant Pavel Chekov in a game of baqlaq on Starbase 56. 

When Chekov and fellow USS Enterprise (NCC-1701) crewmember Lieutenant Hikaru Sulu were attacked by two birds-of-prey in rapid succession while returning to their ship aboard a Type-4 shuttlecraft, Krag and his ship defended the shuttle and crippled the attacking ships. However, the commander of one of the ships, Captain Puhg was unwilling to admit defeat and destroyed the shuttle, but not before Chekov and Sulu could be beamed to safety aboard the Ghaklor. Chekov then demanded the Ghaklor be turned over to him and Sulu, sending the Klingon crew home in a shuttlecraft of their own and returning to the Enterprise aboard the battlecruiser.
