D5 class

The D5 class battle cruiser was an earlier type of starship used by the Klingon Empire in the 22nd century. They shared some design traits with the Raptor class cruiser used in the same era by the Klingons.

These ships were a flexible design as they could be converted into tankers which could carry precious resources such as Deuterium. (ENT episode: Marauders). They also made use o Multi-spectral sensors and were composed of diffused onded monocrystal. (ENT episode: Judgement).

These ships appeared to have been in common use by the Klingon Defense Force at the time and were much more advanced then the United Earth's Starfleet NX class vessels though the Human hips were capable of surviving battle for a short amount of time. (ENT episode: Judgement & Divergence).

They were armed with two large disruptor cannons located at the bottom of the central section of the main hull. These weapons were mounted on a type of turret platform which allowed the weapon to rotate and fire at enemy targets regardless of direction. (ENT episode: The Augments).
