Here is the 23rd century version of the D-5 Cruiser we just used in the latest adventure. I intentually kept the vessel spartin in design as it is a hold over for the last century and is used as an expendable vessel.

DESCRIPTION AND NOTES
Fleet data: The D5 Cruisers are old even when the first Earth starship (Enterprise) made contact in the 22nd Century. When newer warships came along the Klingon’s converted into heavy Deuterium Tankers. The D5 Tankers can carry 100,000 cubic meters of Deuterium.
Like many of the Klingon ships the D5 was used well into the 23rd century. Kor and Kang with a cloaking device.

Noteworthy vessels/Service records/encounters: IKS Bortas/served as a patrol vessel/ encountered the Enterprise NX-01 damaged under the command of the Klingon Captain Duras; IKC Klothos/a civilian version of the vessel hauling Deuterium/Enterprise NX-01 under the Klingon Captain Kor.

Here is the sites that i used to determine the design and was cloase.
