The D-5 class cruiser was in use by the Klingons in the 22nd and 23rd centuries.3 These ships were the mainstay of the Klingon fleet during that period, and many variations came into service. This particular model was modified to act as a Deuterium fuel tanker,4 with eight large tanks affixed to the hull.5 Various internal re-arrangements were also made to the ship to facilitate its non-combat role.

The Klingon tanker appeared in Enterprise "Marauders". Normally you would expect a tanker to have no weapons, but given that this is a Klingon ship I have chosen to arm it but make it pretty weak. We learn little about the ship in the episode, but since it is such an old design, and one belonging to a Federation ally, I have avoided mostly "unknowns" in the specs table.

The dispersive armour is mentioned as being present on the Bird of Prey design stolen by Malik; I assume this is standard for Klingon ships of this era.
