The D5 class battle cruiser was a type of warship in service with the Klingon Imperial Fleet during the mid-22nd century.
In service as early as 2147, the D5 class Klingon battle cruiser was fully documented in the Vulcan database. (ENT: "Marauders", "Judgment")
General specifications
Like many of its successors in the Imperial Klingon fleet, the D5 battle cruiser was distinguished by a roughly bird-like form, with an elongated primary hull and angular wings and warp nacelles.
The fully-armed D5 cruiser was considerably more advanced than Earth Starfleet's most powerful vessel during the 2150s, the NX-class starship. Like its Raptor-class counterpart of the same era, the D5 was outfitted with standard multi-spectral sensors as well as disruptors and photon torpedo launchers.
Structurally, the composition of the D5 included diffusion bonded monocrystal. (ENT: "Judgment", "Divergence")
Freighter variant

The D5 freighter variant was an adapted version of the standard D5 battle cruiser, which included eight under slung deuterium tanks. Considerably less advanced than its battle cruiser counterpart, the D5 tanker was significantly less armed, notably lacking the ventral disruptor cannon common to the class.
Unlike the D5 battle cruiser, the D5 tanker was considered to be inferior to an NX-class starship. (ENT: "Marauders")

Background
D5 master systems status
In DS9: "Once More Unto the Breach", Kor said that his old ship, the IKS Klothos, was a D5 class vessel, but it was seen in TAS: "The Time Trap" to be a D7 class. This does not present much of a particular problem, however, since Kor's senility was a key focus of the episode, he could have just gotten this minor detail confused in his aged mind. Another possibility is that Kor could have commanded two starships Klothos, just as his rival James Kirk commanded two Enterprises of slightly different classes. Yet another possibility is that the writers on both Deep Space Nine and Enterprise, like Roddenberry himself, did not consider TAS to be canonical and simply ignored any possible discrepancies.
Apocrypha
In the Star Fleet Battles series of games, the D5 class is a newer, but smaller ship roughly based on the older and heavier D6 and D7 classes. It was primarily used as a light cruiser and was designed for rapid production and high combat power in a smaller class ship. The Klingon Empire was capable of building at least eighteen ships of this class per year. Considered an exceptional design in comparison to other races ships of that class, it was noted for its manuverability and superior weapons arcs. Like most Klingon ship classes, many D5s were modified into a wide variety of variants during the General War.
