The Klingon Deep Space Fleet commissioned a special study to see if the D-7 class could be made more efficient by the introduction of new technology. Of the various proposals, the one from the Kozenko Design Bureau (known by the designation KDB-1104) was the most interesting and the most radical. Smaller and easier to build than the D-7, the KDB-1104, also known as the D-5 class, was ingenious in the manner of the changes made. Frontal armament was reduced by one phaser, but the improved Type-1 phasers were used, and the disruptors were given a wider arc. The amidships phasers were considered superfluous and reduced to Type-3 phasers. Introduced in 2275, the D-5 class featured a capacity of eight shuttlecraft, two science labs, three transporters, three tractor beam emitters, and was armed with two Type-A missile launchers, four banks of Type-3 disruptors, one bank of Type-1 phasers, two banks of Type-2 phasers, and six banks of Type-3 phasers. The D-5 remained in production until 2300, when it was replaced by the D-5K refit, introduced in 2288. The D-5K replaced the Type-A missiles with Type-B, and replaced the Type-2 phaser banks with Type-1s.

The D-5G war commando cruiser variant was introduced soon after in 2277; designed for use in ground assaults, it became the workhorse of the Klingon Marines. Good shielding and multiple transporters made it a dangerous ship for fast raids. Beyond the base D-5 model, the D-5G featured two additional shuttles (for a total capacity of ten), five transporters, and was armed with two banks of Type-1 phasers, two banks of Type-2 phasers, and four banks of Type-3 phasers.

Also introduced in 2277, the D-5C war command cruiser variant was designed as a squadron leader. While its command facilities were not equal to a D-7C command battlecruiser, they did not need to be. The D-5C featured stronger shields than the D-5, a capacity of nine shuttlecraft, two science labs, three transporters, and four tractor beam emitters, and was armed with two Type-A missile launchers, four banks of Type-3 disruptors, two banks of Type-1 phasers, four banks of Type-2 phasers, and six banks of Type-3 phasers. The D-5C remained in service until 2295, when it was replaced by the D-5L refit, introduced in 2283. Much like the D-5K refit, the D-5L replaced the Type-A missiles with Type-Bs, and replaced the Type-2 phasers with Type-1s.

The D-5D war drone cruiser was introduced in 2279, and was designed for direct combat with missiles, rather than independent long-range bombardment. Beyond the base D-5 specifications, it featured a capacity of ten shuttlecraft, and was armed with six Type-B missile launchers, two banks of Type-1 phasers, two banks of Type-2 phasers, and six banks of Type-3 phasers.

The D-5Y war cloaking cruiser was introduced in 2281, and was the largest Klingon vessel equipped with a cloaking device. The original D-5 was a very successful spaceframe to base a light cloaking cruiser on, but it wasn't designed to carry a cloaking device, which served in the variant's detriment. Aside from the cloaking device, the D-5Y was otherwise largely identical to a base D-5.

The D-5W new heavy cruiser variant was the final variant of the class, introduced in 2294. Similar to the Federation's NCA-type Miranda class new heavy cruiser; both were light cruisers built up to heavy cruiser mass and power. The class featured eight shuttles, two science labs, five transporters, and three tractor beam emitters; it showed an increase in overall engine power, as well as increased armaments consisting of two Type-B missile launchers, four banks of Type-3 disruptors, six banks of Type-1 phasers, two banks of Type-2 phasers, and four banks of Type-3 phasers.

When the Klingon High Council thought that the new heavy cruisers would require a squadron flagship, the D-5WC (DWC) new heavy command cruiser variant, was the result, though only a few were produced. The additional flag command and control equipment was ultimately considered to be a waste on the design. Introduced in 2298, The D-5WC took the base D-5W and provided improved shielding, a ninth shuttle, a fourth tractor beam emitter, and the Type-2 phasers were replaced with Type-1s.
