The D-6 class was the original standard Klingon cruiser, until it was replaced by the more powerful D-7 class. Compared with the D-7, the D-6 had fewer phasers and the disruptors had shorter range. One of the four shipyards building D-6 and D-7 class ships never converted to D-7 production, however, and continued to produce D-6 class ships; they may have been kept in production originally to fill the light cruiser or destroyer roles. Most of the additional D-6 production was used for variants. One of the hidden strengths of the Klingon Empire was the ready availability of cruiser hulls for support variants.

The D-6 battlecruiser was in service in 2250, and featured a crew complement of 440, a capacity of eight shuttlecraft, four science labs, five transporters, and three tractor beam emitters, and was armed with two Type-F missile launchers, four Type-2 disruptor banks, and seven Type-2 phaser banks. The D-6 remained in production until 2282, when it was replaced by the D-6B refit, which was introduced in 2270. The D-6B had stronger shields; it replaced the Type-F missiles with Type-As, and added a bank of Type-3 phasers. The D-6B remained in service until 2297, when it was superseded by the D-6K refit, introduced in 2285. The D-6K replaced the Type-A missiles with Type-Bs, the Type-2 disruptors with Type-3s, and three of the Type-2 phaser banks were replaced with Type-1s.

The D-6D drone battlecruiser was also in service in 2250, and was a conversion of the D-6 designed to provide long-range fleet fire support, though it was also capable of direct combat. D-6D ships were not intended to patrol alone, and usually operated as part of a fleet. The D-6D was largely similar to a D-6, but had a crew complement of 460, a capacity of ten shuttles and only a single transporter facility; it was armed with six Type-B missile launchers and seven Type-2 phaser banks. The D-6D remained in service until 2284, when it was replaced by the D-6DB refit, introduced in 2272. The D-6DB was largely identical, but featured stronger shields.

A third variant in service in 2250 was the D-6G commando cruiser. Designed as a heavy assault transport to deliver troops to planetary combat, the D-6G was one of the most effective commando ships in known space. Because heavy cruiser hulls were difficult to spare, however, very few were built. The D-6G had a capacity of 510, stronger shields than the D-6, carried up to eleven shuttles, had nine transporters for delivering troops, and boasted four tractor beam emitters. It was armed with seven banks of Type-2 phasers, and remained in production until 2282, when it was replaced by the D-6GB refit, introduced in 2272. The D-6GB variant featured improved shielding, and added a bank of Type-3 phasers; it remained in service until 2284.

Romulan

The Klingon Empire provided the Romulan Star Empire with advanced ships and technology starting in the early 2260s. The most important ships supplied were nine older D-6 class battlecruisers. While those were strictly second-rate ships to the Klingons, they were, at the time, the most powerful ships in Romulan hands. Later, the Romulans acquired more D-6s from the Klingons and converted some into variants.

The D-6R (KR) battlecruiser was introduced circa 2263 and featured a crew complement of 400, a complement of nine shuttlecraft, and was equipped with four science labs, five transporters, and three tractor beam emitters. It was armed with two Type-G plasma torpedo tubes, three banks of Type-1 phasers, and four banks of Type-2 phasers. The D-6R remained in service until 2288, when it was superseded by the D-6RB, which was introduced in 2276. The D-6RB (KRB) variant featured featured stronger shields than the D-6R.

The Romulans only converted a few of their D-6s to the D-6RG (KRG) commando battlecruiser variant. It was based upon the Klingon D-6G commando battlecruiser. The D-6RG, introduced in 2263, featured a crew complement of 500 — which included 250 Marines, housed in four barracks — a capacity of 12 shuttlecraft, and was equipped with four science labs, nine transporters to aid in deploying troops, and four tractor beam emitters. The D-6RG was armed with three banks of Type-1 phasers, and four banks of Type-3 phasers. The D-6RG remained in service until 2290, when it was superseded by the D-6RGB (KRGB) refit, introduced in 2278. The D-6RGB, while similar to the D-6RG, featured slightly stronger shielding.
