Notes

The D-5 class cruiser was in use by the Klingons in the 22nd and 23rd centuries.2 These ships were the mainstay of the Klingon fleet during that period, and many variations came into service. The basic hull was adapted into a Deuterium tanker model as well.5

Comments

Seen in the Enterprise episode "Judgment", the D-5 was markedly superior to the NX class. The D-5 was first mentioned by Kor in "Once More Unto the Breach". It is capable of warp 6. The ship has only been seen firing a single weapon; occupying the space normally associated by the torpedo launcher, this weapon seems more like a pulse disruptor cannon - though it is hard to tell exactly, certainly the Enterprise withstood far more hits from this weapon than it did from the photon torpedoes fired by the D7 in "Unexpected".

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.

It is hard to judge the size of the D-5, but it looks considerably smaller than the D-7. My estimate is based on the window spacing on the size comparison image.
